SERVICES & PRODUCTS

Chamfer edge

CHAMFER

Chamfers are an improvement on a normal negative rake tool, ultimately allowing for a tool technician to program a simple tool path without compensation to produce the desired material surface.

CONTROLLED RADIUS

Edge Technologies produces diamond tools measuring a standard 0.25 microns peak-to-valley but have the ability to produce very low waviness tools measuring down to 50 nanometers.

STYLI

A stylus is a small 90 degree pointed diamond used for cutting master record recordings. Some styli require a mounted heating wire to bring the diamond to a required temperature for optimal machining.   

Boring and Milling Tool

 MILLING TOOLS

Our chemical process polishes the diamond edge without removing the diamond from the shank. This means less time, less money, and fewer steps for a resharpened tool.
