Doudle-sidelapping Machine

Main Application：

This machine can be used for double-side lapping and polishing of metal parts such as valve plates, valve discs, friction plates, rigid sealing rings, cylinder piston rings, and oil pump vanes; as well as non-metallic hard and brittle materials including silicon, germanium, quartz crystals, glass, ceramics, sapphire, gallium arsenide, and lithium niobate.

Equipment Principle and Features:

The machine body adopts an optimized design with a double-arm structure, featuring high rigidity and strong pressure-bearing capacity, which can meet the requirements of high-speed and stable operation under high load.

The lower plate, upper plate, and sun gear are each driven independently by motors. All motors are variable-frequency motors controlled by variable-frequency speed regulators, enabling operation at any speed within the effective setting range. They can achieve smooth stopping, acceleration, deceleration, and direction reversal, effectively preventing the breakage of thin and brittle workpieces.

The planetary gear transmission adopts a pin tooth structure, ensuring stable transmission without impact. The planetary gears have a long service life, and the pin teeth can be lifted to facilitate loading and unloading.

During the descending process of the upper plate, fast descent and slow descent are set. The slow descent stroke is adjustable within the cylinder stroke range, and the slow descent speed can also be freely adjusted according to the impact resistance of the workpiece.

This machine adjusts and controls the processing pressure through a precision electro-pneumatic proportional valve. The processing pressure can be set according to different processing technology requirements, with high pressure control accuracy.

It adopts an advanced PLC system and a touch screen operation panel. All process parameters and process recipes can be modified and set on the touch screen, and the entire processing process can be automatically completed according to the set process parameters.

The gears and all moving parts are equipped with a centralized lubrication device, ensuring good lubrication and a long service life of the entire machine.
