Lapping machine: A grinding machine that uses a grinding tool coated or embedded with abrasive to grind the surface of a workpiece. Mainly used for grinding high-precision flat surfaces, inner and outer cylindrical surfaces, conical surfaces, spherical surfaces, threaded surfaces, and other profiles in workpieces. The main types of grinding machines include disc grinding machines, rotary shaft grinding machines, and various specialized grinding machines.

1、Disc grinder: divided into single disc and double disc types, with double disc grinder being the most commonly used. In a dual disc grinder, multiple workpieces are simultaneously placed in a cage located between the upper and lower grinding discs, and the cage and workpiece move parallel to each other through an eccentric or planetary mechanism with a motion plane. The lower grinding disc rotates, while the upper grinding disc parallel to it can either not rotate or rotate in the opposite direction to the lower grinding disc, and can move up and down to press the workpiece (pressure adjustable). In addition, the upper grinding disc can also rotate around the column by an angle with the rocker arm for easy loading and unloading of workpieces. Double disc grinding machine is mainly used for processing two parallel surfaces, one flat surface (requiring additional attachments to press the workpiece), outer cylindrical surface, and spherical surface (using grinding discs with V-shaped grooves). When processing the outer cylindrical surface, due to the fact that the workpiece needs to slide and roll, it is necessary to choose the appropriate type and arrangement angle of the retaining frame holes and grooves. The single disc grinder only has one lower grinding disc, which is used to grind the lower surface of the workpiece. It can process workpieces of different shapes and sizes on the same disc, with high grinding accuracy. Some grinding machines also come with mechanisms that can automatically calibrate the grinding disc during the grinding process.

2、Rotary Grinding Machine: The workpiece or grinding tool (adjustable grinding ring or grinding rod) is driven to rotate by a spindle that rotates in both directions. It has a relatively simple structure and is used for grinding inner and outer cylindrical surfaces.

3、Specialized grinding machines: Depending on the type of workpiece being ground, there are center hole grinding machines, steel ball grinding machines, and gear grinding machines.

In addition, there is a type of centerless grinding machine that uses a principle similar to centerless grinding to grind cylindrical workpieces.

Characteristics of Grinding Machine
1、Automatic grinding machines are high-speed grinding machines and precision grinding machines. Using sandpaper tape, the electrical appliances are sprayed with Japanese Izumi, Fuji, and whole machine plastics, and the color is microcomputer color.
2、The guide rail is a Taiwan linear guide rail.
3、The scraper adopts a card lock design, which can adjust the deformation of the scraper and ensure the quality of grinding.
4、This automatic grinder, high-speed grinder, and precision grinder can be used for mechanical scraper and manual scraper grinding.
5、Special grinding wheel design, no pressure sensation on the grinding cloth belt, no deformation during scraping, no ripple phenomenon, ensuring grinding accuracy.
6、Grind the angle degree to match the efficiency of various special printing.
7、The grinder is equipped with a dust cleaning device, which can reduce industrial pollution and benefit the health of workers and the maintenance of equipment.
8、Automatic grinder, high-speed grinder, and precision grinder are easy to operate without the need for professional skills.
