Equipment Highlights

Equipment Highlights

·The size of the machine is compact, save space; the gantry structure, good stability, strong rigidity.

·The maximum pressure of the machine tool is 1200kg, the pressure of the double cylinder is pressurized, and the pressure is precisely controlled by the electro-hydraulic proportional valve.

·The rotation speed of each shaft of the sun gear, inner ring gear, upper plate and lower plate can be adjusted separately, and the overall speed can be matched.

·The upper tray is made of special stainless steel, which has strong corrosion resistance and deformation resistance; the upper and lower trays have built-in cooling and heating structures, and the temperature of the disk surface is controllable.
