Note: The lapping process can only remove a slight thickness of the workpiece surface. If ultra-thinning (≤100μm) is required, a special thinning machine is needed.

Working Principle

1. As a precision lapping equipment, the workpiece rotates counterclockwise on the lapping disc, obtains pressure through gravitational force, and simultaneously generates relative rotation and friction with the lapping disc, thereby achieving a precise lapping effect and ensuring the flatness and smoothness of the workpiece surface.
2. The equipment adopts an oil-pressure suspended guide rail design. The guide rail floats the moving parts through pressure oil to achieve pure liquid friction with extremely low friction coefficient, which can effectively ensure the stability of movement and processing precision. Combined with diamond dressing file/diamond hone, it can precisely dress the lapping disc, ensuring that the lapping disc achieves excellent surface roughness and further improving processing precision and consistency.

Core Product Features

1. Ultra-High Precision Processing: The flatness of the lapping disc can reach ±0.002mm, and the flatness of a workpiece with a diameter of 50mm after processing can reach 1/4 wavelength, meeting the strict requirements of high-end precision processing.
2. Adjustable and Controllable Pressure: Adopts weight block pressure application method, which can flexibly adjust the pressure according to the workpiece material and processing requirements, adapt to the lapping and polishing standards of different workpieces, and ensure processing consistency.
3. Convenient and Efficient Operation: Adopts PLC program control and touch screen operation panel. The rotation speed of the lapping disc, timing duration and lapping time can be directly input and set on the touch screen. The speed is adjustable, the operation is simple and easy to understand, which reduces the difficulty of manual operation and improves production efficiency.
4. Constant Temperature and Anti-Deformation Design: The lapping disc is equipped with a water-cooled circulation system. The cooling circuit does not pass through the surface of the lapping disc and will not wash away the lapping fluid. It can accurately control the temperature at a low temperature with an error of only ±1℃, effectively solving the problem of workpiece deformation caused by heat generation during lapping, and improving product qualification rate and processing efficiency; at the same time, the gravity-operated cylinder has a protective locking function, which can maintain its original state in the event of power failure or air failure, ensuring the safety of equipment and workpieces.
5. Batch Processing Capacity: Equipped with 3 workstations, supporting 3 sets of independent pressure and self-locking systems, which can perform lapping and polishing of 3 sets of workpieces at the same time, greatly improving the efficiency of mass production and reducing production costs.
6. Complete Auxiliary System: Equipped with a lapping fluid (or coolant) circulation and automatic filling system, ensuring uniform supply of lapping fluid, reducing waste, and at the same time ensuring the stability of the processing process and extending the service life of the equipment.
