Graphite machining has unique difficulties. The most frequent quality issues are edge chipping, surface burrs, dimension drift and heavy dust. As a brittle material, graphite cannot be bent or deformed like metal; chipping often leads to direct scrap. Many processors use standard metal cutting parameters and end up with unstable yield.

Key Advantages

Diamond cutting tools adopted: Longer tool life and smoother machined surface for bulk graphite production.

Process adjusted by graphite grade: Separate cutting schemes for isostatic graphite, extruded graphite and carbon-carbon composites.

In-process dimension inspection: CMM testing to lock tolerance before shipment.

Machining allowance reserved for post-treatment: Ready for impregnation and SiC anti-oxidation coating.

Typical Products

EDM graphite electrodes, sintering graphite fixtures, graphite crucibles, graphite plates, graphite rods, graphite bearing blocks, graphite insulation parts. Jiecheng Graphite adjusts processing plans according to graphite material grade and end-use environment to reduce rejection rate.
