Machining metal stamping dies requires cutting steps, at least cutting or sawing the blanks on the die steel raw materials, and then rough machining. The surface and size of the fresh blank is relatively poor, so you need to go to the previous grinder for rough grinding. At this time, it belongs to rough machining, so the size requirement is not high, and the tolerance of 50 threads is generally enough. After rough machining, heat treatment is required. Generally, heat treatment is processed by a special heat treatment plant. There is not much to introduce in this area.
After the heat treatment, finishing is required. Generally, the grinding machine is used for finishing first. At this time, the size requirements are more stringent. Generally, the accuracy is about 0.01. Of course, this accuracy is not. The specific accuracy requirements should also refer to the complexity and precision of the metal stamping parts that need to be processed by the metal stamping die.
After the grinding machine is processed, the design drawings before the installation are processed. Generally, the hole is threaded first, and then the wire is cut to cut the required size and shape according to the drawing, and then the milling machine, CNC, etc. are used as the case. This specific also depends on the complexity of the metal stamping parts.
The equipment needed for metal stamping die includes sawing machine, lathe, wire cutting, electric spark, milling machine, drilling machine, grinder, etc. These are also equipment that a qualified metal stamping die fitter needs to operate skillfully.
