Lapping Machine

The lapping machine is a grinding device that smooths the surface of a workpiece using a lap coated or embedded with abrasive material.

Lapping Machine

It is primarily used for grinding high-precision planes, inner and outer cylindrical surfaces, conical surfaces, spherical surfaces, thread surfaces, and other profiles on workpieces.

The main types of grinders are disc grinders, rotary grinders, and various specialized grinders.

The grinder control system is controlled by a PLC and has a human-machine dialogue interface for display, where text is used for communication.

The human-machine dialogue interface allows for communication regarding equipment maintenance, operation, faults, and other relevant information.

The operation interface is user-friendly and easy to operate, with program control that is intuitive and convenient.

For safety reasons, misoperations in abnormal conditions are not allowed.

Real-time monitoring, fault detection, error alarms, and ease of maintenance are also provided.


A grinding machine grinds the surface of a workpiece using a lap that has abrasive coating or particles embedded on it.

It is primarily utilized for achieving high precision on plane surfaces, as well as for grinding inner and outer cylindrical surfaces, conical shapes, spherical shapes, threaded surfaces, and other profiles present on the workpiece.


Grinding is a crucial technique in ultra-precision machining, known for its high precision and versatility in processing materials. However, traditional grinding methods suffer from low efficiency, high cost, inconsistent precision, and quality control issues, limiting its application.

This project aims to address the limitations of traditional grinding and enhance the overall level of grinding technology. The project team has developed a new high-speed grinding machine that maintains nanometer-level precision and quality while reducing cost and improving efficiency.

Advanced processing and manufacturing, as well as optoelectronics, are two of China’s key development industries and are heavily reliant on grinding and processing technologies. The new grinding machine has already been adopted by more than a dozen units in China and has been exported to Australia twice, receiving positive feedback from users both domestically and internationally.

While the technology is currently limited to processing individual parts, further improvements are needed to optimize the grinding process parameters, expand the processing range, and enhance the performance of the machine. This will lead to wider practical use and commercialization, promoting its widespread application.
