Comprehensive category for machine tools that perform material removal processing of metals, resins, wood and other materials using cutting tools. Primarily handles stationary cutting machines including NC lathes, CNC milling machines, machining centers, drilling machines, boring machines, gear cutting machines, and hobbing machines. Supports high-precision machining through program control to general machining with universal machines, used for manufacturing precision parts such as automotive components, aircraft parts, molds, and jigs. Clearly distinguished from non-cutting processing machines like grinding machines and electrical discharge machines, as well as press machines and forming machines, targeting only processing machines based on the fundamental principle of material removal using cutting tools.
