Generalinformation ofSpphire surface polishing machineK900NC:

Usage:

This machine is mainly for doublesided lapping and polishing of hard, fragile materials like metal and nonmetal ones,especially for optical glass, crystals, quartz wafer,sapphire glass, lithium niobate,gallium arsenide, ceramic chips, ferrite, silicon wafer, valve plate, friction plate, stain sealings, cylinder piston ring, oil pump vane .

Features:

1.Japanese "SMC" electrical proportional valves and tension sensor closed loop feedback control, the pressing process switched linear pressure control the accuracy ± 2KG to meet a large area, thin pieces difficult, high-precision machining requirements.

2.The use of touch-screen interface, Swiss “ABB” and PLC program control system ensures the stability and safety of the machine and the system is compatible with grating thickness control system with best resolution of 0.001mm.

3. The use of Japanese “NSK” spindle shafting achieves precision and durability of the machine.

4.The operation would be more convenient since one handle can control the fast and slow rising and descending of upper plate.

5.Unique safety retaining mechanism could prevent the emergency of plate falling caused by accident expiration and power failure.

6. Unique automatic floating positioning device fo upper plate reduces the trouble caused by staggering and proofreading dics.

7. Ring gear and the retaining plate semi-automatic lifting system not only gives convenience to place and take workpiece and occlusal gear, but also could change the cruise to meet the matching requirement of high and low positions.

8.The operation of the whole machine driven by mono motor,, which makes perfect match for upper plate, lower plate , center wheel and speed. The cruise achieves forward and reversal and meets the demand of disc repair technic.
