Glass-reinforced thermoset polymer matrices are synthetic polymer reinforcements that have been developed and used in many applications.
CCT Precision Machining is an industry leader in Thermoset Machining/Garolite Machining. We are able to maintain tolerances, create features and produce parts that even the material manufacturers deem impossible. By using high speed spindles capable of turning at 30,000 RPM, tightly controlled work envelopes and cutting edge work holding systems, CCT Precision can machine high pressure laminate components from the most simple part to the most intricate part on any of the 25+ machines in our facility.
- 27” x 15” x 13” Work Envelope
- Tolerances to +/- .00025” (0.006 mm)
- Hole Diameters to 0.003” (0.076 mm)
