Material: POM ; tolerance: dowel holes ±0.015mm other holes and dimensions are ±0.05mm
Characteristic: easy to deformation after machining
CNC machining process:
1. rough machining left 3.0mm, then put in boiling water for half a houre:
2.strike product on work plate by double sided adhesive, machining left 1.0mm;
3.place product at room temperature for 3 days;
4.strike product on work plate by double sided adhesive, precision machining to meet all tolerance requirment 。
in rough milling, the CNC speed is 5000 RPM, the feed is 4mm, in precision milling, the CNC speed is 12000 RPM. rough and precision milling both using white stell milling cutter
