CNC Machining is the best precision process for metal prototype manufacturing

Sanwo CNC Machining Services Capacity

Though Production tools and methods are changing day by day, CNC machining is always standing out as the most accurate process for metal parts manufacturing from long time ago till now. Unlike the additive process, CNC machining is a subtractive process to manufacture a product directly from a 3D design using the computerized numerical control programming controlling the tools and cutters; it removes material from a Block of Metal and gets the product out from machining. At Sanwo, we have more than 1000 square work plant for only CNC machines and more than 30 Big Size high precision CNC machines for only Metal Machining; in the meantime, our experienced programmers and technical engineers are skillfully to make the product manufacture fast and cheaper than every supplier in China for prototyping and metal low volume productions.

CNC Cutting, CNC Milling and CNC Turning

Sanwo CNC machining Center includes the CNC Cutting, CNC Milling and CNC Turning process. Our CNC Cutting and milling process with advance software and quick-change cutters allows for complicate internal and external 3D geometries Shape metal to be Generated in a rapid delivery time, and our CNC Turning capacity is available for one piece prototype through to hundred and even hundred-thousands Pieces production . our General Tolerance for CNC Metal cutting, milling and turning is DIN-2768-1-Fine, We are willing to follow your 2D assembly tolerance on every part from your project and provide you the best possible precision tolerance.

EDM Sparking and Grinding

EDM short for Electrical discharge machining is a process for Metal square pocket holes, CNC unreachable under cuts and internal cavities making, the EDM process is to make the metal difficult and impossible area out in shape by bath eroding.

At Sanwo we also provide Grinding service for work piece surface like high precision shaft on centrality and roughness or assembly contact surface on flatness to get the most precision match.
