Machining Guidelines
Boron nitride ceramic materials have excellent machining properties and can be processed into complex shapes with very small tolerances as required. The following matters should be paid attention to in the processing:
- Use standard high-speed steel cutting tools; for harder PBN-E and composites, use cemented carbide or diamond tools.
- Grinding can be carried out as required, and standard taps and dies can be used for threads.
- Always keep the process dry; do not use cutting oil or coolant.
- Keep tools sharp and clean; avoid negative inclination tools.
- Use caution when jamming and clamping to avoid excessive pressure.
- Utilize down-milling technology to prevent missing edges and corners.
