What is a mold core:
The mold core refers to the precision part used for the critical operation of the center part of the mold.
The general structure of the mold core is extremely complex, the processing is very difficult, and the cost is very high.
Often the labor expenditure for manufacturing is much greater than the material itself.
The choice of mold core material is directly related to the cost of the mold and the service life of the mold.
What are the common mold core materials?
The materials used for general processing mold cores are P20, 738, 738H, 718, 718H, NAK80, 2316, 2316A, S136, etc., and the materials for hardened molds are 2344, 8407, SKD11, SKD61, etc.
When producing this single crystal cutting tool, the information we need to confirm with the customer includes:
the type of mold core that the customer needs to process, the size of the cutting tool, the size of the arc, and the size of the included angle.
It would be even better if there were detailed drawings of the Tools.
The following is a simple drawing drawn by one of our customers when he consulted us about single-crystal tools for processing optical die cores.
Single crystal cutting tools produced by Moresuperhard can achieve dimensional accuracy:
1. The size of the tooltip arc can be 120°~140°
2. Arc accuracy can achieve R1±0.05, and higher requirements can achieve R1±0.01.
3. The surface roughness of the tool is within 10nm
4. Edge waviness within 200nm
