YHM77110 High-precision Vertical Double-sided Grinding (polishing) Machine
This machine is used for double-sided grinding and polishing of metal parts such as valve plates and friction plates, as well as thin parts made of non-metallic hard and brittle materials such as sapphire and ceramics.
● The machine tool adopts gantry structure, with good stability and strong rigidity, and the maximum polishing pressure is 1200kgf.
● Double oil cylinder pressurization, pressure sensor feedback, electro-hydraulic proportional valve to precisely control the pressure.
● The 4 speeds of sun gear, inner gear, upper plate and lower plate are independently set.
● The upper and lower plates have built-in constant temperature design structure.
