SS 440C Machining Capabilities Capability Technical Description Jucheng Advantage Hard Turning Turning 440C in its fully hardened state (58-60 HRC) using PCBN (Polycrystalline Cubic Boron Nitride) inserts. Eliminates the need for grinding on some geometries, reducing cost while maintaining tight tolerances (+\/- 0.005mm). Bearing-Grade Grinding Precision ID\/OD grinding to achieve roundness and concentricity within 1 micron. We produce custom bearing races and rollers that meet ABEC dimensional standards. Cryogenic Treatment Deep freezing parts after heat treatment to convert retained austenite to martensite. Ensures maximum dimensional stability and hardness for parts used in precision metrology or aerospace. Superfinishing Polishing ground surfaces to Ra 0.05\u00b5m to reduce friction and wear.
