The main purposes: this equipment is mainly used for lapping and polishing both sides of the parallel surface of thin metal and hard brittle nonmetal parts, such as silicon, sapphire crystal, ceramic, optical glass, quartz crystal and other semiconductor materials. Technical characteristics: the machine is according to four planetary gears motion principle. This machine adopts the way of the inner gear ring lifting. The cylinder pushes spiral cam to drive the ring gear lift when it ups and downs. It is controlled by a three manual valve device which is installed in the right side. The gear ring can be adjusted. Double motor driving. The main motor drives the upper lapping plate, the lower lapping plate and the inner gear ring to rotate by a series of variable speed, and the sunwheel is driven by the auxiliary motor. Both the main motor and the auxiliary motor are frequency conversion. The lower lapping plate, inner ring gear and the sun wheel rotate in the same direction, but the upper lapping plate opposite. The machine is equipped with safety lock cylinder, when the upper lapping rises to the up limitation, the inserting plate comes out to prevent it falling down so that ensure the operator and equipment safety. Plc control is flexible and reliable. It adopts touch screen as man-machine interface device, which displays the alarm and in real time information of machine status, it is very friendly and with large amount of information.

Main purpose it's designd for grinding parts with two parallel grinding wheels simultaneously. Various high precision and thin parts with parallel side surfaces, no matter they are made in metal or nonmetal material, can be processed. Such as bearing, valve, seal, oil pump vane, piston ring, ceramics, etc. Technical characters: 1. Cnc system chooses mitsubishi e60 withfriendly interactive interface and reliable performance. 2. The parts’ processingfor the upper and lower surfaces is simultaneous with high precision, and without assisted positioning ( such as disks ) 3. The program about the double disc grinding and wheel dressing control makes itto get high precision grinding. 4. Wheel head feed adopts precise ball screwunit. Feeding scale value: 0.001 mm. 5. Wheel head spindle is driven byconverter, 150-950rmin. 6. The motor of the feeding carrier adoptsconverter control; the speed is 1-10rpm. 7. Filtered by magnetic and paper tapetwo steps, the coolant recycle after oil temperature controll er. 8. Adopt hinged carrier plate mechanism(patent no:zl200820052659.1), which is easy to open to make aconvenient change and dressing of the grinding wheel. 9. Themachine body adopts casting boxlike structure with good shock absorption andreliable rigidity and thermal stability; wheel heads spindle are set byvertical configuration.
