Double Sided Lapping & Polishing Machine

Product name:Double Sided Lapping & Polishing Machine

Item:DS-9B1M5T

Details:

Application:
Mainly used for high-precision double-sided lapping and polishing of optical glass, sapphire, ceramic, crystals, semiconductors, and other hard and brittle materials.Especially for the processing of ultra-thin workpieces.

Main feature:
1. Pressure precision control: PLC+PT+precision decompression realizes pressure open loop control;
2. Precision transmission system: high-precision, small-backlash, all-gear transmission;
3. Lower plate support: high-precision flat fluid bearing support;
4. Pin-tooth drive internal and external gears adopt pin-tooth drive, which extends the service life of the carrier and is convenient for maintenance;
5. ​​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.
