Equipment Highlights

Equipment Highlights

● The machine tool has upper and lower throwing discs. The diameter of the upper disc is 1300mm, and the diameter of the lower disc is 1900mm. The upper disc can be turned over at 90 degrees. The lower disc is a power disc driven by a frequency conversion motor to drive the reducer to rotate. The upper disc is driven by the lower disc to rotate. The upper and lower discs can be used as installation workpieces or polishing discs. The size of machinable workpieces is ≤ 1850.

● The upper plate can be horizontally moved to form a reciprocating motion to ensure the flatness and smoothness of the workpiece processing. The horizontal movement stroke of the upper plate is 1100mm.

● The machine tool is controlled by PLC and touch screen. The process parameters under different pressure conditions can be preset in the touch screen. The lower disk motor is driven by variable frequency motor to realize stepless variable frequency speed regulation.
