Boron Nitride Machining
Shanghai Yuepeng is equipped with multiple CNC lathes and CNC milling machines, backed by extensive machining experience. We offer customized boron nitride ceramic products and profiles with extremely tight tolerances, tailored to customer requirements. During the machining process, the following precautions should be observed:
- Boron nitride ceramic materials can be machined using standard high-speed steel cutting tools. For harder and composite materials, carbide or diamond tools are recommended.
- Grinding operations can be performed as needed, and standard taps and dies can be used to machine threads.
- The machining process should always be kept dry, with no need for cutting oils or coolants.
- Cutting tools should be sharp and clean, and tools with negative rake angles should not be used.
- Care should be taken when clamping and securing materials to avoid applying excessive pressure. Climb milling techniques should be used to prevent edge and corner chipping.
