Typical Machined Parts
Processing Methods
1. The machine tool is compact in size and saves space; it adopts gantry structure, which has good stability and strong rigidity.
2. The maximum pressure of the machine tool is 1200kg, the double oil cylinder is pressurized, and the electro-hydraulic proportional valve precisely controls the pressure.
3. The speed of each shaft of the sun gear, inner gear, upper plate and lower plate can be adjusted independently, 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 a built-in cooling and heating structure, and the temperature of the disk surface is controllable.
