Using Mirror Sodick EDM and its producing technology

Sodick mirror EDM is a highest state with metal cutting, also it is the most effective methods of improve the everyday living of mechanical components and mold die components. Just after mechanical cutting, Mirror is a reflection of a image to became good roughness. Regardless of the kind of stainless steel processing methods, there’s always kept the micro marks in the top of machining parts, undulating area phenomenon is looked, which can often be seem after roughing machining together with the naked eye, and after precision finishing the finish, the valley phenomenon continues to can be observed by magnifying glass or perhaps microscope. This kind of surface has the name surface finish. The parameters of your surface roughness is made up with highly parameter, spacing ranges and integrated ranges.

The dependence on Sodick EDM mirror is key in the pattern of the metal manufacturing, specially: for machining a mold accessories, striking die manufacturing, carbide punch and die places manufacturing. Mirror powder compounded Sodick EDM compounded powder mirror machining is actually a new technology developed a lot. By adding the specific number of conductive silicon, aluminum and various fine powder, it may possibly change the spark discharge state, significantly slow up the surface roughness, as well as surface properties (dress yourself in, corrosion, etc. )#) is definitely greatly improved.

Using the heat treatment while in the mold spare portions

The heat treatment process will be to make the parts purchase the required hardness, scenario, engineer should strictly control the inner stress to assure the dimensional firmness when machining portions, different materials have various methods of heat procedure. With the recently available development of pattern industry, more and many more types of materials are being used, besides Cr12, 40Cr, Cr12MoV, carbide, structure punching manufacturing which require bigger work intensity plus force demanding, the fresh material alloy powder snow is good various, such as V10, ASP23, such material includes high thermal firmness and good organization of your state

Let’s take an illustration of die components by using material Cr12MoV, if quenching after uncertain machining, there’s huge stress left while in the parts, which easily bring on crack when finely-detailed machining or alternative manufacturing process. so provide draw the poise after quenching get rid of the quenching stress. Quenching temps controlled within 900-1020 ℃, in that case cooled to 200-220 ℃ cooked cooled, then immediately melted 220 ℃ tempering, using these services is called one-time hardening approach, it can purchase a higher strength plus wear resistance, it can improve the performing life of the blanking punch which should currently have higher abrasion. In case the machining parts by using complex shapes and most corners in development, tempering is deficiency of to eliminate worry, we should arrange the worry relief or aging treatment for a variety of times to release the worry.

For V10, APS23 and various alloy parts, it may possibly withstand high-temperature tempering, we will use the 2nd hardening process by using 1050-1080 ℃ quenching, in that case tempering with temps 490-520 ℃ to get multiple times, you may obtain more great impact toughness plus stability, it works for the a stamped mold which frequently failure to chipping. The buying price of powder alloy fabric is higher, nonetheless its performance is definitely good, it will often be widely used when you need it in the metal manufacturing.

The analysis of the mold precision manufacturing

A set of mold is composed of many spare,and the quality of the mold accessories  made a direct impact on the quality of the whole mold , and the final quality of the    parts is guaranteed by the high precision machining.

As for the most of the domestic manufacturing enterprises, the precision machining   usually includes  grinding, EDM and fitter treatment. Meanwhile ,we should control the deformation of parts, internal stress, shape tolerances , dimensional accuracy, and many   other technical parameters, in the real production ,the operation will be more difficulty.

For the mold parts machining, generally known as adaptive processing for different  materials, different shapes and different technical requirements .

According to the different shapes of the parts ,we can divide the parts into  three   categories:they are shafts, sheet metal and shaped parts, their common process includes   heat treatment  - grinding - Electric Discharge - surface treatment-assembly

1:heat treatment

By heat treatment process, the die components can reach the required hardness while controlling the internal stress, ensuring dimensional stability when machining the parts,   Normally ,different materials have different way to do the heat treatment. With the recent development of the mold industry, there’re more types of materials to be used, Beside the material Cr12, 40Cr, Cr12MoV, carbide, but for some work intensity, force demanding convex and concave mold, the choice ,we also use V10, ASP23 for better  thermal stability and good performance .

2 Grinding

There’re three types of grinding,: surface grinder, cylindrical grinding and tooling grinding .We should  strictly control the finishing deformation and cracks when grinding, even for the micro crack ,it will influence the overall mold performance.

3:  Electrical machining

In the modern mold factory,  electrical machining is necessary , especially for the molds of the precision sheet metal stamping parts.All kinds of special-shaped with high      hardness parts can be machined by electrical machining ,it is divided into two kinds of wire EDM and E.D.M.

4: Surface treatment and assembly

The marks and Scar is the place where the stress is concentrated ,also it is the     source of crack propagation, so after processing, we should do the surface hardening to the parts and  dispose of processing problems by grinding ,and do the radius treatment to the   sharp holes and sides . In generally ,there will be about 6-10μm deterioration of the hardened layer when E.D.M, the color is gray,  hardened layer is brittle .so before using ,we need to eliminate the hardened layer by  surface polishing .

During the  grinding, electric machining, some machining will be magnetized ,it is   very easy to suck some small things, so before  assembly ,we should prior to the workpiece for demagnetization and clean the surface with ethyl acetate.In the assembly process,  we should prepare all mold accessories for assembly ,and make lists of assembly,the assembly usually start from the mounted guide pins and bushings, and then loading mode frame and punch and die, and adjust  the gap, especially for groups with punch and die gap then  mold testing, write the detailed report. If any problems,we’re able to check by    reverse thinking method, it is from the process after step forward, from finishing to roughing, check each until you’re able to find the  problem.

The maintenance of metal stamping tools

Today we’d like to introduce some precautions of punches and dies when the maintenance of stamping stamping manufacturing


1:We should pay attention to the original conditions of the molds when disassemble or assemble the punches and dies .It is convenient to load the mold later.

2:If adding the lips or shifting ,we should mark the thickness in the spare parts and make good records.

3:Before replacing the punches ,it is necessary to make sure whether the punching die can be fit perfectly .and check the clearance between insert punch and die block is smooth and uniform.

4: After repairing the punches by grinding,the length of the punch will be shorter,so we need to add the clips to achieve the effective length.

5: If changing the broken punch ,we should find out the reasons and check whether it is caused by clipping in the dies,if yes ,when assemble the punch and die ,whether there’s enough gaps .

6:We should place the die in a flat level when assemble the dies,then knock the surface of the dies by copper rods. Never place the dies in a inclined direction with large strength.There must be chamfer under the bottom of dies,in order to check whether it’s in the same level after assembly.

7: After assemble the punch ,die and other mold accessories,we should check whether all parts are installed wrong or installed backwords ,check the taper is traffic or not,check whether the new replacement parts need to reduce the material .Check he mold part which is need to be locked ,check the screw of the mold plate ,check the part whether is locked from the inside to the outside.

Note die sharpening and repair

1 edge wear and burr measurement 

Field habits determined by hand stamping burr size and determine the sharpening timing, the error is too large. Of course, the degree of edge wear and edge blunt only by detecting stamping burr height and thickness, burr distribution uniformity of size, shape and position accuracy and blanking plane quality stamping, the master edge wear, edge change blunt, identify the timing of sharpening. 

General stamping burr height micrometer available. To improve measurement accuracy, each measured three last consecutive punching punch and die member, and each mold accessories is measured at least 3 to 5 points, averaged. For complex shape and thin materials and small size, precision stamping, available tools, microscopes, the optical projector precision measurement. 

2 metal stamping size and shape and position accuracy measurements 

After repeated sharpening, the die size will change. In particular, the majority of> 3 to 6 mm material thickness of plate and slab material blanking part blanking die, smooth consideration by the die hole punch to shirk the workpiece or waste, on the small conical recess mold hole, to prevent workpiece or scrap gathered and plug in the die. The die edge the wall pour out material, after grinding the upper surface of the horizontal size will inevitably produce an increment. Excessive gain in order to avoid repeated sharpening its size exceeds the allowable value, leaving out of the stamping size unqualified.Therefore, before sharpening should refer to the values ​​given are calculated and measured stamping after grinding size, to stamping size qualified so far. 

Inaccurate positioning device or gauge pin wear, rotating, feeding into the distance deviation increase. For continuous blanking part, often be caused by stamping inside and outside round concentricity error is too large, dividing the incision problems such as uneven cloth, it is in the repair test mode requires special attention. 

Measurement tryout stamping presses the normal operation for some time, punching a certain number of stamping. Measurement of hedge pieces should first observe the red section quality to determine the uniformity of the gap. Then detect the burr height and uniformity of last crossed detected size and shape and position accuracy. 

3 clearance measurement 

Accurate determination of the new system and overhaul or repair to all kinds of die clearance inspection and molding, one of the primary means of repair mode quality, die fitter and punching to adjust the basic skills of the workers. 

Plasticine indentation and fill the mold cavity is in a case where there is no practical and accurate clearance measurement instrument, more economical, accurate and reliable clearance measuring method. With a uniform thickness that is greater than twice the stamping material thickness does not exceed 5 mm plasticine, relying on manual clamping gently closed state to meet the design and then gently mold to remove the plasticine, observation and measurement to stay in plasticine on the upper and lower mold indentation, you can get the exact gap value. For blanking die, indentation on the mold can be controlled just pressed into the plasticine 0.8 to 1.5mm position; forming die majority should be embossed in the clamping state. However, stretching, flanging and the like of the mold, but also due to the simultaneous detection of the mouth portion of the fillet radius of the die size and uniformity, so when the platen punch into the die 2 to 3 times the material thickness of the punch member is appropriate. 

4 die installation and commissioning of 

Installation and adjust the die must be particularly careful. Because die especially large and medium-sized die, not only very expensive, but also the weight trace difficult to move, personal safety should always be the first place. Unlimited digital device, die, in particular, nor die guide mechanism between the upper and lower mold should be added to a mat board. Clean up in the press table to be tested mold clamping state placed in the appropriate position of the press countertops. Selected ram stroke press process documents and die design requirements in the mold onto the table before the raised bottom dead center position and raised to 10 ~ 15mm larger than the mold is closed, by adjusting the slider rod, mobile mold, to ensure that the handle is aligned with the handle hole and appropriate die height. General blanking die first fixed lower mold (do not tighten) and then fixed on the mode (tightening), platen T-bolts are advised to use the appropriate torque wrench to tighten (mold) to ensure that the same bolts with consistent and ideal pre-clamping force. Manual winding the tight thread appears due to physical, gender, texture error caused by the preload is too large or too small, can be effectively prevented the same thread PRELOAD ranging, causing lateral displacement of the upper and lower molds, the gap change the stamping process, the nibbles stripping blade mouth, such as failure occurs. Tryout before the mold to conduct a comprehensive lubrication and normal production of the materials used in air travel to start the die 3-5 recognition mold functioning properly and try red. Adjust and control the punch into the die depth, check and verify the die-oriented, feeding, shirk, lateral pressure and suppress institutions and device performance and operational flexibility, and then appropriately adjusted so as to achieve the best technical condition. Small, medium and large die trial red 3,5,10 discontinued beginning of the seizure, red 10, 15, 30, qualified try for re-examination. Crossed detection, red cut surface and burr inspection ORCHID Dimensions are in line with the shape and position accuracy requirements before delivery of production. 

5 standard prefabricated parts and reserves 

For die standard components should focus on prefabricated and leave some reserves for selection at any time in the process of manufacturing and repair die. In particular, the main working parts, including: a variety of round punch side of the blade, scrap cutter, and a variety of templates, die handle, mold, lateral pressure device before backgauge device ...... should full range of specifications reserve 3 to 5 sets or more, commonly used sizes, should be more reserve.

The mold speed milling Technical Overview-Part1

I. Introduction 

In the modern  mold production, with increasing high aesthetics and functional requirements of the plastic parts, plastic parts internal structure is designed to be more and more complex, the exterior design of the mold are becoming increasingly complex, free-form surface increasing proportion corresponding mold structure is also designed to be more and more complicated. Mold Accessories processing technology put forward higher requirements, should not only ensure the manufacture of high precision and surface quality, but also to the pursuit of the beauty of the machined surface. With the deepening of the high-speed processing technology, especially in promoting the development of machine tools, CNC system, tool systems, CAD / CAM software and other related technology, high-speed processing technology has been increasingly used in the mold cavity processing and manufacturing. 
CNC high-speed machining as the most important one in the mold manufacturing advanced manufacturing technology, is a set of efficient, high-quality, low power consumption at an advanced manufacturing technology. Compared to conventional machining, the cutting speed and feed speed has been greatly improved, and the cutting mechanism is not the same. Cutting speed cutting essential leap unit power metal removal rate of 30% to 40%, a 30% reduction in cutting forces and tool cutting life expectancy has increased by 70% to stay in the workpiece, cutting heat The amplitude decreased low-level cutting vibration almost disappeared. With the increase in cutting speed, rough material removal rate per unit time, cutting the time to reduce the processing efficiency, so as to shorten the product manufacturing cycle, improve the market competitiveness of the products. At the same time, high-speed processing of a small amount of fast-forward the cutting force reduces the chip's high-speed discharge to reduce the the workpiece cutting forces and heat stress deformation, increase the possibility of poor rigidity and thin-walled parts machining. Due to the reduction of the cutting forces, the speed increases so that the cutting system frequency away from the low-order natural frequency of the machine, while the surface roughness of the workpiece is most sensitive to low-level frequency, thereby reducing the surface roughness. Electrical processing and the step of grinding and polishing can be substituted in the mold high-hardened steel (HRC45 ~ HRC65) during processing, the use of high-speed cutting, thereby avoiding the manufacturing of the electrodes and time-consuming electrical processing, significantly reduce the fitter grinding and polishing amount. A growing need in the market for thin-walled mold workpiece, high-speed milling can also be successfully completed, and in high-speed milling CNC machining centers, a mold clamping can complete the multi-step processing. 
High speed machining of the mold process to produce a huge impact, changing the traditional mold used annealing → ​​milling machining → ​​heat treatment → grinding or EDM → hand sanding, polishing "complex and lengthy process, and can even be used to replace all of the original high-speed machining process. High-speed machining techniques can be applied to the the hardened mold cavity directly processing (especially semi-finishing and finishing), EDM electrode machining, Rapid Prototyping Manufacturing has also been widely used. Mass production practice shows that the application of high speed cutting technology can save about 80% of the mold in the subsequent processing manual grinding time, saving nearly 30% of the processing costs, the mold surface machining accuracy of up to 1 m, the tool cutting efficiency can be increased by 1. 

Second, high-speed milling machine 

Speed ​​cutting technology is one of the main development direction of cutting technology to a higher level with the development of the basic technology of CNC technology, microelectronic technology, new materials and new structure. Due to the mold special processing and high-speed processing technology, the technology and process systems for high-speed machining of molds (machine tools, CNC system, tool, etc.) put forward higher requirements than the traditional punch and die. 
　 A high stability of the machine tool support member 
High-speed cutting machine tool bed support member should have a good dynamic and static stiffness the the hot stiffness and damping characteristics. Most of the machines are high-quality, high rigidity and high tensile gray iron as a support member material, add some machine tool companies still base a high damping characteristics of polymer concrete to increase its vibration resistance and thermal stability This will not only ensure the machine accuracy and stability, but also prevents the cutting tool chatter. The closed bed design, overall casting bed, symmetrical structure of the bed with clouds of ribs is also an important measure to improve machine stability. The company's R & D departments of some machine tools in the design process, but also using modal analysis and finite element structural calculations to optimize the structure of the machine more stable and reliable support member. 
　 2. Machine spindle 
The performance of high-speed machine tool spindle is an important condition for achieving high-speed machining. High-speed cutting machine tool spindle speed range to 10000 ~ 100000m/min, and 15kW spindle power greater than. Axial gap between the shank and spindle control spindle compressed air or cooling system is not greater than 0.005mm. Also requires the spindle performance (that has a very high angular acceleration and deceleration) with rapid acceleration, rapid accurate stop at the specified location, high-speed spindle often hydrostatic bearings, aerostatic bearing, hot-pressed silicon nitride (Si3N4) ceramic bearings magnetic bearing type structure. Lubrication to use more oil lubrication and jet lubrication technology. Spindle cooling generally use the spindle internal water-cooled or air-cooled. 
　 3. Machine drive system 
To meet the needs of high speed machining of the mold, the high speed machining machine tool drive system should have the following characteristics: 
(1) a high feed rate. Studies have shown that, for small diameter tool to improve the speed and the amount of feed per tooth helps reduce tool wear. The feed rate range of 20 ~ 30m/min, such as the use of a large lead ball screw drive, feed rate up to 60m/min; linear motor allows speeds of up to 120m/min feed. 
(2) a high acceleration. Three-dimensional complex surface contour of the high-speed machining requirements drive system has good acceleration characteristics, to provide high-speed feed drive (fast forward speed of 40m/min, 3D contouring speed of 10m/min) to provide 0.4m/s2 to 10m/s2 acceleration and deceleration. 
Most machine manufacturers closed loop position servo control lead to large-size, high-quality ball screw or lead screw bulls. With the development of motor technology, advanced linear motor has come out, and successfully applied to theCNC machine tools. No mass inertia advanced linear motor driven CNC machine tools, advanced, hysteresis and vibration problems faster servo response speed and improve the the servo control accuracy and precision machining. 
　 4. CNC system 
Advanced CNC system is a key factor to ensure the quality and efficiency of high-speed machining of mold complex surface, the basic requirements of the numerical control system of high-speed machining of the mold: 
(1) high-speed digital control loop (Digital CONTROL loop), including: a 32-bit or 64-bit parallel processor and 1.5Gb more hard disk drives; very short sampling time of a linear motor 
(2) the velocity and acceleration feedforward control (Feed forward control); crawl control of the digital drive system (Jerk control). 
(3) advanced interpolation method (based on NURBS spline interpolation), to obtain a good surface quality, precise dimensions and high geometric accuracy. 
(4) pretreatment (Look-ahead) function. Requires a large capacity buffer register, pre-reading and checking more than one block (such as DMG machine can block up to 500 the Simens block system up to 1000 to 2000), in order to be processed surface shape (curvature) occurs change to take timely measures to change the feed rate to avoid excessive cutting. 
(5) error compensation function, including fever caused by thermal error compensation due to the linear motor spindle quadrant error compensation, the measuring system error compensation. In addition the requirements of high-speed machining of the mold on the data transmission speed is also high. 
(6) data interface, such as RS232 serial port transmission speed of 19.2kb, while many state-of-the-art machining centers have adopted Ethernet LAN (Ethernet) for data transfer speeds of up to 200kb. 
　 5. Cooling lubrication 
High-speed machining using coated carbide cutting tools without cutting fluid, in the case of high-speed, high-temperature, efficient cutting. This is because: the high speed rotation of the milling spindle, cutting fluid to reach the cutting area must first overcome a great centrifugal force; even if it overcomes the centrifugal force into the cutting area, may also be due to the high temperature of the cutting area and immediately evaporated, the cooling effect is small even not; cutting fluid causes the intense temperature changes of the cutter blade, easily lead to cracks, so dry cutting oil / gas cooling and lubricating. This manner can be provided with high pressure gas quickly blown away by the cutting of the cutting zone, so that the large amount of cutting tropical go, while the atomizing the lubricant can be provided in the the tool blade portion and the workpiece surface to form a thin layer of micro-protective film, can be effectively extend tool life and improve the quality of the parts of the surface.

The application of high-speed stamping technology

With the rapid development of electronic communications, electrical appliances, automobiles and home appliances and other products, the growing demand for precision stampings, technical requirements are also increasing, and the application surface more and more widely, so a large number of ordinary presses can not meet the production and super mass production, production and technical requirements. High-speed precision press high speed, automation and continuous punching is an effective way to improve press productivity. Due to the number of times per minute than the tonnage of high-speed precision presses slide stroke similar to the ordinary presses more than five times higher, so high-speed precision presses not only high precision stamping parts, surface quality, and long mold life. 

In recent years, the stamping technology to keep the speed, precision and intelligent direction, the momentum of development of advanced high-speed presses, and therefore the emergence of a number of high-speed precision press and ultra-high-speed precision presses, such as Germany Las special company, Münster, Switzerland nbsp, Schuler, Germany, Japan, the rate of energy and electricity production companies, the development of small-tonnage high-speed precision presses, Number of strokes up to 2,000 times / minute, 3,000 beats / minute, 4,000 times / minute. In the load state, but also up to the standard super precision requirements. This indicates that high-speed precision press technology has developed to the ultra-high-speed ultra-precision stage. 

Some foreign companies of small tonnage of high-speed precision presses Number of strokes divided into four speed grades: normal speed ≦ 250 beats / min, times high speed> 250 to 400 beats / min, high-speed> 400 to 1,000 times / min, super- speed ≧ 1,000 times / minute. Large tonnage of high-speed precision press slide the relatively low number of trips, such as 300 tons of large-scale high-speed precision presses, the number of slide stroke range is only about 160 to 400 beats / min, 100 tons of fin dedicated high-speed precision presses The slide stroke number range is generally about 150 to 250 beats / min. 

Punching speed presses tonnage, slide stroke length and the number of products, process structure and materials process performance, automatic feeding speed and precision of many different elements, it is difficult to use simple numbers as the divided each grade boundaries, Therefore, the international high-speed precision presses range of rapid change is still yet to make a clear definition, usually the punching speed of 5 to 10 times higher than ordinary presses speed collectively referred to as high-speed precision stamping. From the situation of most enterprises in China's high-speed precision press, Chong times speed according to the the average slider minimum and maximum number of strokes or greater than the mean of 10 to 20% of the impulse rate is more reasonable and reference significance standards. Because the maximum number of strokes of the high-speed precision presses slider generally refers to the number of load-stroke. Imbalance presses running significantly increased when the number of trips up to a certain value, the dynamic changes of the dead under the slider, must be resolved so that the quality of the coil material feeding speed, mold performance and life equipment strength, stiffness and precision, the failure of automatic monitoring and stability, vibration and noise as well as lubrication and cooling system and a series of technical problems. Therefore, the application of high-speed precision presses the red times speed is critical.
