What is Precision Machining?
Precision machining refers to the process by which a machinist uses Computer Numerical Control (CNC) equipment to remove excess raw materials and transform remaining materials into specific shapes and sizes, all the while maintaining tolerance, or dimensional accuracy.
CNC precision machining leverages the latest precision technology, including computer-aided design and computer-aided manufacturing software, to fabricate finished materials according to customers’ exact specifications. These precision-machined components are typically small, with tight tolerances.
