MCD/CVD Inserts

JoyJet MCD/CVD inserts provide extreme wear resistance and thermal conductivity for ultra-precision machining of non-ferrous metals, composites, and abrasive materials with superior surface finishes and long tool life.

Properties of MCD/CVD Inserts

  • Hardness: MCD inserts offer extreme hardness (HV9000–10000); CVD diamond inserts also provide high hardness, ideal for high-temperature cutting.

  • Thermal resistance: MCD performs stably in high-precision dry cutting; CVD inserts exhibit excellent heat resistance, withstanding temperatures above 1200°C.


Applicable Materials of MCD/CVD Inserts

  • MCD inserts: Best suited for ultra-precision machining of non-ferrous metals, optical components, and composite materials.

  • CVD diamond inserts: Suitable for high-hardness materials such as high-temperature alloys, hardened steels, stainless steels, and titanium alloys.


Key Considerations for Selecting MCD/CVD Inserts

1. Workpiece hardness:

  • MCD: ideal for soft to medium-hard materials.

  • CVD: recommended for materials with hardness above HRC45.

2. Cutting parameters: 

Optimize cutting speed and feed rate based on the workpiece and application.

3. Insert geometry: 

Choose edge design according to application type (e.g., roughing, finishing, profiling, spherical surfaces).

4. Cooling method: 

Use cutting fluid or air cooling to improve tool life and ensure cutting stability.
