Micro machining services produce tiny components under 10mm with intricate details using micro-tools down to 0.05mm diameter. Achieving ±0.001mm tolerances via high-speed CNC, EDM, it's vital for medical, electronics, aerospace miniature parts like sensors and implants.
What Is Micro Machining?
Micro machining creates parts smaller than 10mm with features under 1mm using specialized CNC, EDM, or laser tools down to 0.05mm. Precision to ±0.001mm.
This subtractive process handles micron tolerances for tiny gears, nozzles. Differs from standard by spindle speeds >60k RPM, vibration-free setups. TwoTrees desktop CNC prototypes micro features.
How Does Micro Machining Work?
Micro machining uses high-speed spindles (60k+ RPM), micro endmills (0.05mm+), and mist coolant on rigid CNC for precise material removal. CAM optimizes chip loads.
Vibration isolation, thermal stability key. EDM for non-conductive. TwoTrees TTC450 mills 0.2mm+ features on soft metals.
