Mold processing requires high accuracy requirements for processing equipment, and there are relatively many equipment involved. Next, I will introduce the accuracy instructions of several processing equipment, hoping to be helpful to you.

1. Electric spark
Mold processing has relatively high requirements for electric spark. EDM is to use pulse discharge between the two poles immersed in the working fluid to produce electrocorrosion during this process, and then erode the conductive material. It is a relatively special processing method. In order to ensure the accuracy of construction, it is necessary to ensure the processing accuracy of electric sparks, which can be controlled at 0.005mm.
2. CNC
The CNC machining range is relatively wide, mainly including the processing of high-order curved surfaces, the processing of positioning blind holes, and the processing of parts with relatively complex shapes. The accuracy requirements are 0.05mm~0.01mm.
3. Drilling machine
Drilling machines are used during mold processing, and the processing technology of the drilling machines is required to be 0.1mm. It is mainly reflected in the thimble vias, processing waterways, screw bottom holes and screw vias.
4. Grinder
The grinders involved in the mold processing process are mainly divided into round grinders and plane grinders, with general machining accuracy between 0.01mm and 0.02mm.
5. Milling machine
Milling machines are mainly used for the straight angle, chamfer and rough processing on the mold. Of course, they can also be used for the cutting of some small parts. The processing accuracy is generally required to be 0.05~0.1mm.
6. Lathe
The lathes in mold processing are mainly used on pins, punches, and guide columns, and the specific processing accuracy is generally 0.02mm.
7. Fine engraving machine tools:
The processing accuracy is: 0.005mm~0.01, which mainly processes CNC processing areas. Some manufacturers need to make copper electrodes and graphite electrode discharge electrodes during the production process. At this time, they can be processed with fine engraving machines, LOGO on the mold, and lettering and relief on our common metals.
