Composite Materials

PCD and diamond-coated tool sourcing for CFRP, GFRP, graphite and abrasive composite machining.

Composite material machining scene with CFRP panel, clean edges and PCD cutting tools
Application review

Industry machining overview

Composite material machining is sensitive to delamination, fiber pull-out, burrs and rapid abrasive tool wear. PCD, diamond-coated carbide and custom geometry tools are often reviewed when clean edge quality and stable tool life are important.

Delamination control
Burr reduction
Abrasive wear resistance
Clean edge quality

Buyer questions before tool selection

  • What composite material and thickness are you machining?
  • Is the workpiece CFRP, GFRP, graphite, honeycomb or stacked material?
  • Is delamination, burr, fiber pull-out or edge chipping the main problem?
  • Is the operation trimming, routing, drilling or countersinking?
  • What trial quantity and quality standard should be used?

Useful information for quotation

  • Composite type, thickness and stack structure
  • Operation type and hole or edge requirement
  • Current defect: burr, delamination, fiber pull-out or chipping
  • Dry or coolant machining condition
  • Trial quantity and expected repeat demand
