Subdivided into 3-axis, 3+2 axis (positional 5-axis) and full 5-axis milling. The cutting tool rotates at high speed and moves along multiple axes to remove material from fixed workpieces.
Key features: flexible for complex 3D geometries, cavities, contoured surfaces and profiling; 5-axis milling can process undercuts and curved surfaces in a single setup.
Typical applications: mold cavities, structural components, engine parts, custom mechanical pieces, complex curved-surface workpieces.
The workpiece rotates at high speed while the cutting tool feeds along the workpiece surface to produce rotationally symmetric parts. It includes conventional turret lathes and Swiss-type lathes for micro precision components.
Key features: high efficiency for rotary parts, excellent concentricity and roundness; Swiss machining delivers ultra-high precision for small, slender components.
Typical applications: shafts, pins, bolts, bushings, connectors, fasteners, micro medical implants.
Specialized hole-making processes including drilling, reaming, tapping and boring, performed on dedicated CNC machines or integrated into milling/turning centers.
Key features: accurate hole positioning, consistent thread quality; boring achieves higher precision and better surface finish for inner diameter holes.
Typical applications: threaded holes, precision bearing bores, mounting holes, hydraulic valve bodies.
Uses abrasive grinding wheels to achieve ultra-high dimensional accuracy and fine surface finish, including surface grinding, cylindrical grinding and internal grinding.
Key features: achieves micron-level tight tolerances and low surface roughness, suitable for hardened workpieces and high-precision mating surfaces.
Typical applications: bearing components, mold inserts, precision shafts, gauge parts, high-precision sealing surfaces.
Removes material via controlled electrical sparks between the electrode and workpiece, including sinker EDM and wire EDM.
Key features: processes extremely hard materials, intricate cavities, sharp internal corners and thin walls without mechanical cutting force or contact stress.
Typical applications: fine mold details, hardened steel parts, complex electrode cavities, narrow slot machining, aerospace turbine blade cooling holes.
Integrates milling, turning, drilling and other processes on a single machine tool, completing all operations in one clamping.
Key features: eliminates clamping errors from multiple setups, improves machining accuracy and production efficiency for complex compound parts.
Typical applications: complex aerospace components, hydraulic valve bodies, precision mechanical parts with both rotary and 3D features.
