Double Sided Lapping & Polishing Machine

Double Sided Lapping & Polishing Machine

Product name:Double Sided Lapping & Polishing Machine



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. Precision pressure control: PLC+PT+electrical proportional valve+tension sensor+low friction cylinder, achieving high-precision pressure control. 
2. Upper plate damping device: vibration damping elastic connection method suitable, ensuring the smoothness of high-speed rotation of the upper plate.(Lapping)
3. Upper plate centering device: It achieves flexible floating of the upper plate, so as not to cause harm to the processed products during the start stop stage. (Polishing)
4. Upper plate anti falling device: mechanical locking and bearing unloading double safety hooks, locking more reliably after the upper plate is raised, with high safety.
5. High precision speed control: Using PLC and human-machine interface self programming to achieve low-speed smooth and synchronous start stop operation control. 
6. Precision transmission system: High precision small backlash full gear transmission, key gears are treated with carburization, and the transmission is smooth and vibration free
7. Lower plate support: high-precision flat bearing support, improving equipment accuracy and smooth operation; Automatic oil pressure detection alarm, avoiding oil-free operation.
8. Maintenance free: automatic centralized lubrication device.
9. Whole machine vibration reduction: Anti vibration structural design makes the equipment more stable.
