Coating properties

This coating generation features a good crystalline structure.
It protects tools perfectly against abrasive wear and is
unsurpassed in graphite cutting.
Diamond Layer

Feature Competitor A

1. High Abrasive wear resistance. D
2. Good Coefficient of friction.(against Al)
3. High Precision. Base material

Advantages

Diamond coated i-Xmill possible to cut graphite workpieces
with substantially greater speeds and in significantly better Crystalline
quality. Competitor B
structure

Applications
1. Precision-structured graphite electrodes.
2. Micro-Electromechanical Systems. (MEMS)
3. Printed Circuit Boards. (PCBs)
4. Ceramics (greens, sintered) Dental, machinery.
