CNC precision machining is a subtractive manufacturing process that involves removing material from a raw material or blank to create a finished product.

The process of CNC precision machining involves several steps. First, the CAD software is used to design the part that needs to be manufactured. Once the design is complete, the CAM software generates instructions for the CNC machine to follow. These instructions include the cutting path, the speed of the cutting tool, and other parameters.

The CNC machine then uses a cutting tool to remove material from the blank, following the instructions provided by the CAM software. The cutting tool can be a drill bit, a milling tool, or a lathe tool, depending on the design of the part. CNC precision machining can create parts with complex shapes and features, such as threads, grooves, and tapers, with high accuracy and repeatability.
