Description

OEM Machining Parts of Stainless Steel from Original Manufacturer in China

Also called precision machining, the CNC machining could reach a very high accuracy in geometical tolerance and dimensional tolerance. With our CNC machines and Horizontal Machining Centers (HMC) and Vertical Machining Centers (VMC), we can almost meet all of your required tolerance grades. CNC machining refers to the machining process proceed by Computerized Numberical Control (CNC for short). It is aided by the CNC to reach a high and steady accuracy with less labor cost. Machining is any of various processes in which a piece of raw material is cut into a desired final shape and size by a controlled material-removal process. The processes that have this common theme, controlled material removal, are today collectively known as subtractive manufacturing, in distinction from processes of controlled material addition, which are known as additive manufacturing.

Precision Machining Processes

The Machining processes are Turing, Facing, Boring, Milling, Drilling, Planning, Shaping, Grooving, Face Grinding, Cylindrical Grinding, Honing, Gear Hobbing, Threading, Lapping, Tapping.


  • Honing. This process uses honing hole diameters ranging from 0.8mm to 100 mm and has depth up to 280 mm. The linear tolerance is 0.001 mm, roundness of 0.0005mm, and straightness of 0.0005 mm. The surface finish is Ra0.05μm. Horizontal and vertical honing machines are used and include single-spindle, twin-spindle, and six-spindle.
  • Turning. This is the process of single point cutting of hardened pieces. Our hard turning process can machine parts with hardness over 58 HRC after heat treatment, maximum turning diameter of 26 mm, turning length up to 100 mm, dimensional tolerance of 0.005 mm, and roughness Ra0.2μm.
  • I.D. and O.D. Grinding. This process enables us to machine shafts with diameter with 750 mm, length within 1000 mm, roundness of 0.0004 mm, and cylindricity of 0.001 mm. The inner holes range from 3 mm to 100 mm.
  • Deburring. RMC's deburring capabilities include electrochemical machining, thermal energy method, and abrasive flow machining. These are used for hydraulic, automotive, and aerospace components with crossing holes and complex inner cavity to meet strict deburring requirements.
  • O.D. Centerless Grinding. This is used for shafts with diameter with 200 mm, length with 400 mm, diameter tolerance of 0.001 mm, cylindricity of up to 0.0005 mm. It is available for both through-feed and infeed.
