1. Benchtop Micro Mills
– Compact and designed for desktop use.
– Used in labs, workshops, and small-scale production.
– Examples: Sherline Mills, Taig Micro Mills.
2. CNC Micro Mills
– Computer-controlled for high precision in complex micro-machining.
– Used for prototyping and micro-part production (e.g., watch components).
– Examples: Roland MDX-540, Haas OM-2A.
3. High-Speed Micro Mills
– Designed for ultra-high spindle speeds (up to 60,000+ RPM).
– Used for micromachining hard materials (cera.jpg)
s, composites).
– Examples: Kern Micro HD, Makino iQ300.
4. 5-Axis Micro Mills
– Allow multi-directional machining for intricate geometries.
– Common in aerospace and medical implants.
– Examples: DMG MORI Ultrasonic 20 Linear, Kern Pyramid Nano.
5. Desktop CNC Micro Mills (Hobbyist/Educational)
– Affordable options for makers and students (e.g., PCB milling).
– Examples: Bantam Tools Desktop CNC, Nomad 3 by Carbide 3D.
6. Ultra-Precision Micro Mills
– Used in optics and semiconductor industries (sub-micron accuracy).
– Often incorporate laser or diamond tooling.
Key Features to Consider:
– Spindle Speed (Higher RPM = finer cuts).
– Travel Range (Small work envelope but high precision).
– Control System (Manual vs. CNC).
– Material Compatibility (Metals, plastics, ceramics).
