China bronze CNC machining products from casting, forging or bronze profiles.
Bronze is a kind of copper-based alloy with Tin. The hardness and strength of bronze increase with an increase in Tin content. The ductility is also reduced with the increase in tin percentage above 5. When aluminium is also added (4 to 11%), the resulting alloy is termed aluminium bronze, which has a considerably higher corrosion resistance. Bronzes are comparatively costly compared to brasses due to the presence of tin which is an expensive metal.
Like many other alloys, copper and copper-based alloys can be formed into highly complex parts, making them ideal for the sand casting and investment casting process. Constant cost fluctuations can make these materials very price sensitive, making waste very costly, especially when considering CNC machining and/or forging as a manufacturing process to produce your production part. Pure copper is not usually cast.
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.
Exactly what the “controlled” part of the definition implies can vary, but it almost always implies the use of machine tools (in addition to just power tools and hand tools). This is a process used to manufacture many metal products, but it can also be used on materials such as wood, plastic, ceramic, and composites. The CNC machining covers many different processes such as milling, turning, lathing, drilling, honing, grinding...etc.
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.

The precision machining workshop at RMC takes care probably the most important step in the supply chain after casting. State-of-the-art vertical and horizontal CNC machining centers and other CNC machines could make sure the accuracy of the castings and guarantee the machined castings are finished on time. All machines are well-organized and taken into production at high production effeciency and good cost-effective mothods. If needed, all the machined dimensions could be measured by the CMM and the related reports could be issued as per customer's requirements.
