CVD thick film diamond (CVD-D), the star among diamond cutting materials
For machining hard-brittle materials such as ceramics, glass and glass-ceramics, hard metal, MMC and fibre composites such as CFRP and GFRP. Due to the lack of a bonding matrix, the diamond content is much higher than with PCD. In the group of ultra-hard cutting materials, binderless CVD-D is one of the hardest, artificially produced diamond cutting materials.
CVD-D is characterised by a high hardness as well as a high wear resistance. These properties make CVD-D the perfect cutting material for machining abrasive materials. Compared to PCD, which is damaged by the abrasive particles due to its soft metallic binder phase, the CVD-D cutting edge remains stable due to its binderless anchoring in the diamond matrix.
If CVD-D is used correctly, the tool life can be increased by up to 10 times (and even more) compared to PCD!

With CVD you can machine materials like:
- Aluminum >10%Si
- GFRP
- CFRP
- MMC
- Carbide >8% Co
- Tungsten copper
- Tungsten
- Graphite fine-grained
- Magnesium
