Graphite machining is not simple cutting. The most frequent defects are edge chipping, surface burrs, dimensional deviation and excessive dust. Unlike metals, graphite cannot be deformed; once chipped, the workpiece is hard to repair. Many manufacturers fail to stabilize quality because they use standard metal cutting tools and parameters on graphite.

Key Advantages

Special diamond tools: Long service life and smooth cutting surface for high-volume graphite processing.

Parameter tuning for different graphite grades: Adjust speed for isostatic graphite, extruded graphite and carbon-carbon composites.

Inspection after each process: Dimension check with CMM to guarantee tolerance before delivery.

Custom surface treatment preparation: Machining reserved allowance for SiC coating and impregnation.
