CNC Machining
SIYUAN Machinery’s CNC machining services are optimized for speed, flexibility, and superior quality no matter the volume of parts. Here’s what sets us apart.Â
Our in-house Machining workshop can assure customers’ casting ,forging or sheet metal parts finished with accurate and strict tolerance.
Our engineers who own 20 years experience and our skilled workers play an important role during the whole project production.
Just castings or forgings without machining can not reach the desired tolerances and surface requirements. However, for most situation, the machining are needed to match the customer’s unique specifications and to make sure that the finished metal parts could work properly with other parts. Even for the investment casting parts, which have much better surface and tolerance grade than other metal forming process. still need additional machining process.
OUR CNC machining service includes CNC machining center service CNC Turning service ,CNC Milling service , Turning Milling Compound Machining, Surface Grinding.
