Machining of Carbon Fiber & Glass-Filled Composites

Solid micrograin carbide tested for milling of carbon fiber and glass-filled composites by Garr Tool available from Cutting Tools aka General Cutting Tools in Chicago Illinois.

There are many challenges to machining composite materials. Keeping the material from delaminating is key for success. Our tools have higher rake angles and combinations of left hand and/or right hand spirals to help eliminate ‘fraying’ of the laminate.

Please specify what type of end cut your job requires (i.e. – no end cut, burr type, end mill type, or drill point)

Having a quality dust collection system helps prolong tool life and quality of parts

‘Clamping’ of part to table can cause stress fractures in material

Please specify what coating, if any, your job requires:

– Polycrystalline Diamond (increases tool life up to 20x of an uncoated carbide mill)

– Amorphous Diamond / DLC (increases tool life up to 10x of an uncoated carbide mill)

– Alcrona Coated (increases tool life up to 5x of an uncoated carbide mill)

– TiCN Coated (increases tool life up to 3x of an uncoated carbide mill)

Series 700 Fiberglass Router – for cutting glass-filled epoxies

Series 701 Kevlar Router – gives a clean edge when trimming Aramid Fibers (Kevlar)

Series 702 Carbon Fiber Router – for trim milling of single layer panels

Series 703 Carbon Fiber Router – for rough cutting of stacked panels with or without honeycomb cores

Series 740 – Dagger

  • For enlarging existing holes in skin panels, but can drill from solid
  • For near reamer finishes in carbon and glass fiber materials
  • Coatings of choice for this series are polycrystalline diamond and amorphous diamond

Series 780 – 8 Facet Point (Non-Coolant Fed)

  • Double angle drill point geometry reduces cutting forces to eliminate exit burrs
  • Works well in carbon fiber especially when the honeycomb core is either titanium or aluminum
  • Works in glass-filled epoxy, harder plastics, softer steels, CFRP (Carbon Fiber Reinforced Plastic), and aluminum
  • Can be coated with a variety of coatings depending on your application

Series 780K – 8 Facet Point (Coolant Fed)

  • Double angle drill point geometry reduces cutting forces to eliminate exit burrs
  • Works in glass-filled epoxy, harder plastics, softer steels, CFRP, and aluminum when running through-the-spindle coolant
  • Coolant fed tooling is not for use in carbon fiber as it may delaminate the material
  • Coatings of choice for this drill are either Helica or Alumastar

Series 790 – Modified Brad Point

  • Designed for drilling CFRP
  • Excellent entry and exit hole quality
  • Designed to prevent delamination
  • Good for drilling panels and paper honeycomb core
  • Coatings of choice for this drill are polycrystalline diamond, amorphous diamond, or helica for extra tool life
