Precision CNC Machining of an ULTEM® Drill Guide for the Medical Industry

Precision CNC Machining of an ULTEM® Drill Guide for the Medical IndustryGemini Plastics, Inc. manufactured this precision CNC machined surgical drill guide, used to direct a drill bit to a target at precise angle. Precision was key, and we worked closely with the customer to perfect the design and define the inspection requirements for this part.

Working with ULTEM®, a strong, heat resistant plastic frequently used in medical applications, we utilized our modern CNC turning equipment to fabricate the part to its 0.844" O.D., 0.130" I.D., and 1.75" length, then polished it to a 16 RMS finish. Rigorous inspections, including dial caliper, micrometer, dial indicator, and pin gage, were conducted both before and after buffing to ensure the overall dimensions were within the very tight +.000"/-.001" tolerances and that the true position on the diameters was within .003". We successfully delivered this high-quality component, along with material certifications and inspection verifications, to the customer within a 6-12 week turnaround.
