YHM77110 Vysoce přesné vertikální oboustranné lapování povrchu
This Lapping equipment is mainly used for grinding and polishing both sides of the parallel surface of thin metal and hard brittle nonmetal parts, such as valve plate, friction plate, oil pump blades and sapphire etc.
Technické znaky
Technical characteristic：
● It uses Gantry structure, with good stability and strong rigidity.
● Maximum pressure is 1500 kg, with double oil cylinder, precisely control of pressure by electro-hydraulic proportional valve.
● Upper tray adopts 304 stainless steel, strong corrosion resistance.
● Both the upper and lower plates are equipped with cooling-heating structure, The surface temperature is controllable.
● The speed of the sun gear, inner gear ring, the upper and lower plates can be adjusted independently, and the overall speed can match each other.
● The machine is compact in size, space saving.
Aplikace
The device can be machined, including ceramics, sapphire, etc.
