Custom CNC Milling & Turning Services
High-precision CNC milled and turned parts with tight tolerances down to ±0.005mm. Fast prototyping to mass production -- from 1 piece to 1,000,000+, no MOQ restrictions.
Two Pillars of
Precision
CNC Milling
Our multi-axis CNC milling services tackle the most complex geometries -- from intricate aerospace housings to precision optical components. With 100+ milling centers, we deliver consistent accuracy at any volume.
CNC Turning
Specializing in rotationally symmetric and cylindrical components, our CNC turning department -- anchored by 350+ Swiss-type turning centers -- produces micro-precision parts with exceptional concentricity and surface finish.
