YHM77115 high precision vertical double-sided grinder

The machine is a high-precision, high-efficiency (grinding and polishing) high-end CNC machine tool that can withstand great grinding (grinding and polishing) pressure. The equipment has the functions of precise loading of large pressure, controllable workpiece thickness and size, rapid dressing of superhard grinding disc, etc. It is mainly used for double-sided grinding (grinding and polishing) of thin parts made of non-metallic hard and brittle materials such as valve plate, valve plate, friction plate, rigid sealing ring, cylinder piston ring, oil pump blade, etc. and silicon, germanium, Shi Ying crystal, glass, ceramic, sapphire, carbon arsenide, ferrite, lithium niobate, etc.

Equipment Highlights


Equipment Highlights

(1) The equipment is equipped with a double-screw guide pressure loading system and a precise closed-loop control system of the grating ruler, so that when the equipment works under a large working pressure, it can better ensure the stability of the grinding and polishing process and quality.

(2) The equipment adopts a high-rigidity, high-speed, high-precision hydrostatic bearing support turntable and independent motion multi-axis sealing device, which improves the yield and efficiency of sapphire processing.

(3) the use of electric spindle high-speed linear dressing device to trim the diamond grinding disc, improve the accuracy of the diamond grinding disc retention and efficiency.

(4) The upper plate floating structure composed of spring and universal joint bearing and automatic horizontal correction device are used to improve the stability and uniformity of high pressure polishing loading.
