Micro Machining Basics

Micro machining is specialized ultra-precision CNC manufacturing for miniature tiny components with micro-scale features. We adopt ultra-fine micro cutting tools, high-speed micro spindles and precision positioning systems to produce micro holes, micro grooves, micro thin walls and micro complex contours for high-end precision industries.

Micro Machining Frequently Asked Questions

Standard CNC uses regular tools above 0.5mm with micron-level rough tolerance. Micro machining uses ultra-fine 0.01mm tiny cutters, 80,000RPM high-speed spindles, closed-loop micro positioning systems and cleanroom environment to process miniature micro features with sub-micron ultra tight tolerances that ordinary CNC cannot achieve.

Choose micro machining if your part has miniature dimensions, micro holes, micro thin walls, sub 0.01mm tiny features, medical biocompatible micro implants, semiconductor sensor micro hardware or micro mold inserts requiring ultra smooth micro surfaces.

Yes. Our micro machining workshop is ISO13485 certified, stable processing Grade5 titanium, medical PEEK, 316L stainless steel and biocompatible plastics, with full biocompatible surface treatment solutions for implant micro components.

We fully support STEP, IGES, SLDPRT, X_T, STL, CATPart, 3DM and DXF 2D drawings. Complete 3D surface models are required for complex micro feature programming.

Our minimum micro cutting tool diameter reaches 0.01mm, enabling micro holes, micro slots and micro grooves as small as 0.01mm, with stable thin wall machining down to 0.02mm thickness without deformation.
