Mechanical Tooling Toolmaking blanks
Single-Crystal Diamond Tool Blanks
Single-crystal pieces prepared to be made into precision cutting tools.
Good to know
- Crystal orientation influences cutting-edge preparation.
- Blank dimensions must allow for the final tool geometry.
- Inclusions and surface damage matter when producing a continuous edge.
