YH2M8432 Màquina lapidadora de doble superfície

This machine can be used for lapping/polishing double-surface of thin components such as glass/ceramics/sapphire/carbon arsenide/ferrite/ lithium niobite .

Personatges tècnics

Característiques tècniques:
● 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;
● Gear ring up and down can be realized through cam bushing driven by air cylinder;
● Sun wheel is driven by 1.5KW motor with reduction gears;
● Lower polishing plate, and inner gear rings are directly driven by reduction gears, stepless variable frequency for speed-regulating, stable start &stop without impact.
● 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.
● All control parts adopt 24v power supply, which can assure safety of the operator and equipment.

The device can be processed workpiece including valve plate, friction plate, rigid seal ring, cylinder piston ring, oil pump blades, silicon, germanium, quartz crystal, glass, ceramics, sapphire, gallium arsenide, lithium niobite etc.
