This machine is mainly used for light guide plate, valves, ceramic, sapphire, cell phone panels, metal materials such as precision mass production of small parts and large parts of the single-sided polishing. The machine has four processing jobs, the appropriate configuration pressurized cylinder four parts. Grinding disc counterclockwise rotation of the workpiece to be machined parts to drive the rotation ring, cylinder pressure on the parts to be machined lend, to be machined parts for the relative friction and grinding disc polishing operation to achieve the purpose of the machine. The machine comes with hydraulic suspension repair disk body, the grinding surface grinding disc for precision correction. The machine adopts PLC control, touch screen operating system, its speed control, time control, process control and other various operating modes directly on the touch screen settings. The machine frame is welded thick-walled rectangular pipe and eliminate the stress of dealing with aging. Countertops and sinks made of stainless steel, beautiful and clean easy to clean. Machine based on the requirements of high-precision processing technology, compact design, reasonable, body rigidity, smooth non-impact, low noise. 2 Main technical parameters of grinding disc diameter 620mm platen speed from 0 to 60 rev / min (can be set according to customer requirements) Processing range ≤ Φ210mm basin diameter 780mm timing 99 minutes 59 seconds pressurized cylinder four, the maximum gas pressure 90KG grinding disc power source pressure 0.6MPa Total power 5KW 380V 2.2KW 380V Dimensions 1500 × 940 × 2000mm Total weight about 1300kg machine any special needs can be based on user requirements and design, manufacturing
