SINGLE SURFACE LAPPING POLISHING MACHINE
Main Purpose:
Single surface lapping and plishing machines are used for metal parts, such as valve plate, wearing plate, rigid seal ring, cylinder piston ring and oil pump blade, etc.as well as processing thin and hard brittle non-metal components of silicon, germa- nium, quartz, glass, ceramic, sapphire, gallium arsenide, ferrite, lithium niobate etc. such as mobile phone, LCD panel, Tablet pc.
TECHNICAL CHARACTERS:
- Water-cooled with three working stations.
- Equipped with peristaltic pump.
- This machine can exert pressure by weight and pressure plate’s dead weight which can judge the pressure.
- There is cooling water circulation system between the lapping plate and tray to ensure machine running reliable for a long time operation, and achieve the desired grinding (polishing ) effects.
- The machine at work through the editing processing procedure in the man-machine interface?and then downloaded to the PLC. PLC will be run by the current downloaded program
- PLC controlling, which it is flexible and reliable.
- Touch screen, it is convenient to show alert information and state. Besides, the interface is friendly and the information is huge.
- 24VDC of control components, PLC is supplied by isolation transformer, external electric wave interference is lowered, and the safety of the machine is greatly raised.
