Processing mode

1, the machine compact size, save space; using gantry structure, good stability, strong rigidity.

2. The maximum pressure of the machine tool is 1200kg, the double oil cylinder is pressurized, and the electro-hydraulic proportional valve accurately controls the pressure.

3. 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.

4. 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.
