precision watch glass surface lapping polishing machine for Optical glass flat polishing

Precision Vertical Double Surface Lapping Polishing Machine  is  used for precision lapping/polishing of double surfaces of metal parts,such as valve plate,wearing plate, rigid seal ring,cylinder piston ring and oil pump blade,as well as laminated non-metal parts of hard&brittle materials like silicon,germanium,quartz,glass,ceramic,sapphire,gallium arsenide,ferrite,lithium niobate,etc.

Technical features:
1. This machine’s each axis of tray, lower plate ,upper plate bears weight by TRB(tapered roller bearing) and DGRB(deep groove ball bearing),machine precision can be assured;
2. Gear ring up and down can be realized through cam bushing driven by air cylinder;
3. Sun wheel is driven by 1.5KW motor with reduction gears;
4. Lower polishing plate, and inner gear rings are directly driven by reduction gears, stepless variable frequency for speed-regulating, stable start &stop without impact.
5. Upper polishing plate is directly driven by one reduction gears, stepless variable frequency for speed-regulating, stable start &stop without impact, the ideal polishing speed can be achieved for different material polishing.
6. All control parts adopt 24v power supply, which can assure safety of the operator and equipment.

1.Moisture-proof packaging+Wooden Box.
2.Special packing requirements available.
