Product Description
Overview
We offer custom Swiss machining service for steel parts. Our sliding-headstock Swiss-type CNC lathes with guide bushing support automatic bar feeding, live Y/C-axis tooling, cross drilling, tapping, threading, grooving and side milling in one single setup. The guide bushing greatly reduces workpiece deflection and vibration, ideal for slender, small-diameter steel parts with high length-to-diameter ratio. We process carbon steel, alloy steel and stainless steel, covering structural, high-strength and corrosion-resistant requirements. OEM custom from drawings or samples, prototype, small batch and mass production available. Widely used in automotive, hydraulic fittings, sensors, medical hardware, electronics, aerospace and instrumentation.
Key Advantages
✅ Guide bushing design, excellent straightness and concentricity for slim long steel parts ✅ One-setup mill-turn, complete turning + side milling + cross holes without re-clamping ✅ Tight tolerance: standard ±0.005mm, critical features down to ±0.003mm ✅ Mature cutting solution for different steel grades, control chip, chatter and work hardening ✅ Full range of surface treatments for steel: plating, heat treatment, passivation, polishing etc. ✅ RoHS & REACH compliant, free DFM review for micro and slender steel components ✅ High repeatability, stable batch consistency for mass production ✅ Strict QC: CMM, micrometer, thread gauge, roughness tester, hardness test available
