Product description
Parameters
1. Main purpose
This machine is mainly used for high-precision double-sided grinding and polishing of silicon wafers, optical glass, ceramic wafers, quartz crystals, semiconductors and other hard and brittle materials.
1. Pressure precision control: PLC+PT+precision decompression realizes pressure open loop control;
3. Precision transmission system: high-precision, small-backlash, all-gear transmission;
4. Lower plate support: high-precision flat fluid bearing support;
5. Pin-tooth drive internal and external gears adopt pin-tooth drive, which extends the service life of the carrier and is convenient for maintenance;
6. Transmission system: Three motors are driven synchronously. The speed of the upper plate, the lower plate, the ring gear, and the sun gear (either forward or reverse) can be set at any speed. The county has a formula function
