Product Description
Overview
We provide custom CNC turn mill composite machining service for stainless steel parts. Our multi-axis turn-mill centers complete turning, Y/C-axis live-tool milling, cross drilling, tapping, threading, grooving and boring in one single clamping. It avoids tolerance accumulation caused by repeated re-fixturing, ensuring excellent concentricity, positional accuracy and consistent batch quality. Stainless steel features superior corrosion resistance, high mechanical strength, high temperature resistance and hygienic property. We support OEM & ODM, custom by drawings or samples, prototype, small batch and mass production. Widely used in medical equipment, food machinery, fluid valve, marine fittings, automation hardware, sensors, instruments and aerospace.
