boron nitride ceramic materials processing
Because of its excellent machinability, boron nitride ceramics can be processed into complex shapes with minimal tolerance to meet the processing requirements of related products. So what should we pay attention to in this process?
When machining boron nitride ceramic materials, although standard high-speed steel cutting tools can be used for machining, but for the machining of pbn-e and composite materials with hard materials, cemented carbide tools or diamond tools are recommended.
In addition to cutting, the boron nitride ceramic material can also be grinded as required, and the standard tap and die can be used for thread processing. The machining process should always be dry without the use of cutting oil and coolant.
As a cutting tool for boron nitride ceramic materials, it is necessary to keep it sharp and clean, and do not use a negative angle cutting tool. When processing materials, care should be taken to prevent excessive pressure from being applied during clamping and clamping, and the down milling technology should be used to prevent edge and angle missing.
No matter what the processing technology is, the boron nitride ceramic material should always be kept in a dry state, and it should be kept in a sealed bag or a drying oven to prevent moisture, otherwise it may affect the processing effect and the quality of the ceramic material after processing, which is not conducive to its application.
