Machining Vespel® CR-6100

Vespel® CR-6100 can be machined on metal working equipment by standard lathe single point turning.
  • Use carbide tipped tools with a 5° to 15° rake angle at the front face and a positive (0 to 5°) back rake angle. 
  • For longer production runs, diamond tipped tools or inserts provide increased tool life.
  • Use feeds and speeds appropriate for turning aluminum.
  • Coolant is not normally required for turning, unless there is a particular need to maximize dimensional stability. 
  • Turned diameter surface finishes of 63 micro-inches (1.6 micro-meters) are typical using a visual surface finish reference guide.
  • Bushing grooves, axial and spiral type, can be generated using standard carbide tipped broaching tools or end mills.
  • As in machining all fluorocarbon materials, part temperature should be maintained below 572°F (300°C) to avoid the possible liberation of a fine particulate fume. See the DuPont MSDS for Vespel® CR-6100 if more detailed information is required.
