Precision Machining FAQs
What CNC machining capabilities does CIC offer?
CIC offers multi-axis CNC turning, 3-axis and 4-axis vertical and horizontal milling, precision OD/ID/surface grinding, and centerless grinding — covering the full range of rotational and prismatic component requirements from prototype through production.
What tolerances can CIC hold in precision machining?
CIC routinely holds ±.001" on general features and ±.0005" or tighter on critical fit surfaces. Our CMM coordinate measuring equipment verifies critical features in-process and at final inspection.
Can CIC machine complex alloys like titanium and Inconel?
Yes. CIC's experienced programmers and machinists regularly machine challenging materials including titanium alloys (6Al-4V), Inconel 718, 17-4 PH stainless, hardened tool steels, and other difficult materials requiring specific tooling and parameters.
Does CIC offer machining of castings and forgings?
Yes. CIC regularly machines both our own casting and forging pre-forms and customer-supplied castings and forgings. Our experience with pre-form machining helps achieve optimal material utilization and dimensional accuracy.
What is CIC's typical machining lead time?
Lead times vary by component complexity, material availability, and volume. CIC regularly delivers prototype machined parts in 1-2 weeks and production components on competitive lead times. Contact us with your specific requirements for a delivery commitment.
