Composite material processing characteristics

Composites processing is fundamentally different from metal processing. In metal processing, the machined material is softer than the cutting tools, and the machined material will form continuous, serrated intermittent chip deformation during the cutting process. The processing of composite materials is itself a series of brittle destruction processes, in which the impact of the cutting edge causes the hard fiber to shatter, forming a powder or brush-like debris.

Diamond Coated Tools And PCD Tools For Compostie Materials

Composite materials are typical difficult to process materials, easy to tear, burr, delamination, thermal damage and other processing problems, the sharpness, wear resistance and stability of the cutting tools put forward extremely high requirements. For processing composite materials, the tool is usually cut with diamond coating tools or PCD tool.

End Mills for Composite materials

Diamond coated Multi-flute endmill features:

The optimized carbide matrix makes the hardness of the tool matrix high.
Submicron WC particles, which can achieve high wear resistance;
Left/right cross edge design, in order to improve the sharpness of the tool, effectively reduce the lamination and burr generation;
Strong close tooth design, improve processing efficiency and accuracy;
Adopt sharp positive front angle design, reduce chip force and cutting heat, avoid defects such as tear and burr of composite material;
Nano-diamond coating, slow tool wear, tool life doubled.
