Cutting Tools Resist Heat, Hold Size
IMTS 2018: Crystallume’s Demon line of cutting tools is designed for extended cuts in difficult materials.
Useful for moldmaking applications, Crystallume’s Demon line of cutting tools is designed for extended cuts in difficult materials. Long tool life reduces the need to switch tools midway through the application. According to the company, the tools generate very little heat, hold size well, cut parts within tolerance and reduce the need for polishing. They also feature a coating designed to improve high-temperature stability for machining hardened steels.
To make the transition to hard turning, you'll need to switch from carbide to CBN inserts, but that is easier (and more economical) than you might think. It's making the jump to much higher surface speeds that might scare you off. It needn't. Here's why.
Fast CNC processing and high-pressure coolant contribute to removing metal at dramatic rates. But what should a shop know about cutting tools in high speed machining?
The more common twist drill point geometries often are not the best for the job at hand. By choosing the best point for the material being drilled, it is possible to achieve better tool life, hole geometry, precision, and productivity.
