Ultra High Precision Tooling Material

SUMICRYSTAL UP

  • General Features

The field of ultra-precision machining, which includes machining of magnetic discs and polygon mirrors, are seeing rapid developments in recent years. SUMICRYSTAL UP has the performance and the high reliability that makes it the optimal material for creating cutting tools for these applications.

  • Characteristics
  • SUMICRYSTAL UP is a high quality and uniform material with stable wear resistance. Cutting edges do not chip easily.
  • Since the shape is uniform, the amount of allowance removed during formation of the cutting edge is small. Cutting edge formation can be done easily.
  • Standard Type
  • Economy Type

A cubic type with 6 faces surrounded by (100) faces. The growth faces on the periphery are left as is, resulting in a large volume. The unique characteristic of this type is that it is economic.
