CNC Swiss Screw Machining
Our CNC Swiss screw machines produce complex parts up to 1.5 inches in diameter with tolerances as tight as .0002 inches. Secondary capabilities include slotting, cross-drilling, and cross-tapping, reducing downtime while maintaining precision. Ideal for aerospace and medical components requiring high accuracy.
CNC Milling
Equipped with 3- to 4-axis CNC mills, we handle parts up to 18 x 32 inches using dual pallet systems for faster production. Our milling services support large-scale manufacturing with consistent quality, serving industries requiring complex geometries and tight tolerances.
CNC Turning
Our 2-axis CNC lathes machine parts up to 10 inches in diameter, specializing in high-volume runs. With capabilities for secondary operations like threading and grooving, we ensure dimensional accuracy and surface finish quality for industrial applications.
Quality Assurance
We maintain AS9100D and ISO 9001:2015 compliance through rigorous inspections, including first-piece, in-process, and final checks. Advanced equipment like CMMs and optical comparators ensures every component meets exact specifications, supported by AS9102 first-article reports.
Engineering Support
Our engineers collaborate on blueprint reviews to enhance manufacturability, as demonstrated by consolidating a multi-component RF switch into a single stainless steel part. This approach improves performance and reduces assembly steps, delivering cost-effective solutions for clients.
