Custom Swiss CNC Precision Components

Swiss CNC precision components are high-accuracy, tight-tolerance turned and milled parts produced on automated Swiss-type sliding headstock lathes. Designed specifically for complex, slender, and micro-sized components, these machines feed bar stock through a sliding guide bushing while precision cutting tools operate immediately at the point of rigid support. This configuration eliminates deflection, enabling consistent execution of intricate geometries, deep ID/OD turning, cross-drilling, and micro-milling in a single setup.

Backed by mature in-house manufacturing capabilities-from multi-axis programming and precision Swiss machining to rigorous CMM metrology-we deliver production-ready components that align strictly with your engineering standards.

Key Features

Dimensional Accuracy: Maintains strict linear and geometric tolerances down to +/- 0.003 mm, minimizing assembly interference risks in complex mechanical systems.

Exceptional Repeatability: Sliding guide bushing support restrains tool-to-workpiece deflection during continuous automated machining, ensuring stable critical dimensions across production runs of 5,000+ units.

Complex Geometry Integration: Multi-axis live tooling enables simultaneous turning, off-center milling, cross-drilling, and tapping in a single clamping operation, eliminating repositioning errors.

Optimized for Small-to-Medium Slender Parts: Rigid bar-feeding dynamics and reduced overhang make Swiss machining the ideal process for components with high length-to-diameter (L/D) ratios.

Controlled Surface Integrity: Optimized cutting feeds, specialized tool geometries, and high-pressure coolant delivery reduce micro-burrs and achieve smooth as-machined finishes down to Ra 0.2 um.

Tight Tolerance Micro-Features: Capable of producing miniature bores, micro-threads, and thin-walled profiles without structural distortion.

Applications

Automotive: Fuel injection components, sensor housings, ABS valve spools, actuator pins, and turbocharger shafts.

Medical: Bone screws, dental implant components, surgical instrument shafts, pacemaker housings, and orthopedic connectors.

Aerospace: Avionics fasteners, instrumentation fittings, actuator bushings, and hydraulic valve spools.

Automation & Robotics: Precision encoder shafts, miniature gear blanks, linear guide pins, and sensor mounting studs.

Electronics: RF connector bodies, fiber optic ferrules, micro-pins, and structural grounding standoffs.

Industrial Equipment: Hydraulic spool valves, pneumatic fittings, meter measuring spindles, and high-pressure nozzle tips.
