Tight tolerances and intricate geometries are no match for CNC precision machining, which can make what was once thought to be impossible, attainable. It is common practice to employ this technology for producing medium- to small-sized batches of a product's components. Greater precision, repeatability, and productivity are three of CNC precision machining's many benefits. The production and design processes are both made more versatile by this technology. Also, the final quality of CNC machined parts is generally superior to that of conventionally manufactured parts. CNC precision machining has some drawbacks, such as a high entry price and the necessity for qualified operators. The time spent setting up the machine tools and programming the CNC controls also means that this technology is not ideal for mass manufacturing.
