Ceramic Products Processing Suggestions

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 of boron nitride ceramic materials:
Boron nitride ceramic materials can be processed with standard high-speed steel cutting tools. For the processing of harder PBN-E and composite materials, cemented carbide tools or diamond tools are recommended.
Grinding can be carried out as required, and standard taps and dies can be used to machine threads.
The machining process should always be kept dry, without the use of cutting oil and coolant.
Cutting tools should be sharp and clean, and do not use cutting tools with negative inclination.
When processing materials, be careful when jamming and clamping to avoid excessive pressure. Down-milling technology should be used to prevent missing edges and corners.
