The equipment is mainly used for fine grinding and polishing of high precision optical glass, quartz, crystalloid, metal and non-metal high precise plane elements. It's equipped with a high-powered worm reducer and a large-thrusted ball bearing. Deflection of the granite working platform is very small even at different environments and different temperatures. Its plantform made of stainless steel. The water tank is clean, good-looking and easy to wash. The output torque is high.

Based on the LP16A, the active wheel rotation mechanism added to the PL16B Plane Precision Ring Polisher, when processing bigger components it can play a very good function of totation. On the basis of LP16B, SLP16B increased PLC numeriacal control operating system. Operating mode is LCD human-machine interface, thus having the functions of transmission system stepless speed regulation, timing control, counting control, sequence control and remote fault alarm. Equipment operating is very simple and flexible, fully satisfies the requirement of high precision opti-electronic components processing technology. 

On the basis of SLP16B, working ring and correction disk swing mechanism added to SZLP16B, which can ensure the work piece and correction disk can swing back and forth when they are rotating. On one hand the durability of the polishing disk's face form can be well maintained, on the other hand the processing blind can be overcome, durability of the milling disk's face form also can be well maintained, thus working efficiency as well as processing precision enhanced, production cost reduced.
