Glass fiber is a commonly used reinforcing material. It has the advantages of good lightness, insulation, heat resistance, corrosion resistance, etc. However, this material is difficult to machine, it has poor heat conductivity, severe tool wear, low efficiency, and deteriorated cutting conditions. It can also cause problems such as fiber pulling, delamination, and tearing during processing. Glass fiber materials are widely used in many fields, such as aircraft, ships, and automobiles.
PCD (Polycrystalline Diamond) milling tools are engineered for high-precision machining of glass fiber–reinforced plastics (GFRP), carbon fiber–reinforced plastics (CFRP), and other fiber composite materials.
With superior wear resistance, sharp cutting edges, and excellent surface finish, these tools are ideal for applications requiring minimal fiber pull-out, reduced delamination, and extended tool life.
High Precision Cutting – Ensures accurate dimensions and tight tolerances in composite machining.
Exceptional Wear Resistance – PCD cutting edges maintain sharpness over long production runs.
Superior Surface Finish – Reduces fiber protrusion and eliminates fuzzing for a smooth finish.
Reduced Heat Generation – Minimizes workpiece damage and resin melting.
Long Service Life – 10–20 times longer than carbide tools when machining abrasive fibers.

Fr4, as a glass fiber reinforced epoxy resin board, is widely used in circuit board manufacturing and requires extremely high processing accuracy and surface quality. Small holes and narrow grooves on the circuit board are prone to burrs, which affect the installation of subsequent electronic components. Using double-edge milling cutters made of ultra-fine grain PCD material, with sharp， can precisely cut Fr4 materials. PCD double-edge milling cutters in the processing of Fr4 materials not only can complete the processing tasks efficiently， but also can significantly improve product quality and reduce cost increases caused by processing defects.
G10 is an insulating material made of glass fibers and epoxy resin， commonly used in mechanical parts， insulation components， etc. During processing， stable dimensions and no delamination are required. G10 materials have high strength and are prone to delamination and cracking during processing. The symmetrical double-edge design of PCD double-edge milling cutters makes the cutting force distributed evenly， reducing the deformation of the material.
