Micro CNC
High-RPM (60K+ RPM) spindles. Sub-micron positioning.
Watches, medical
Watch movements, surgical tools, electronics, fluidics.
FAQ
Smallest feature size?
Practical 0.1 mm. Below requires laser, EDM, or other micro processes.
Tolerance achievable?
±0.005 mm CNC micro-machining. ±0.001 mm with grinding.
Materials limitations?
Most CNC materials. Smaller tools mean lower torque — material selection per machinability.
Surface finish?
Ra 0.2 µm CNC. Better via grinding (Ra 0.1) or polishing.
Cost premium?
2-5× standard CNC. Specialty tooling, slower speeds, micro-CMM verification.
Major applications?
Watch movements, surgical instruments, microfluidic devices, fiber-optic connectors, medical implants.
