What are the precautions in the operation of internal grinder?

Internal grinder is mainly used to grind the surface and end face of cylindrical, conical or other shapes of internal holes. Grind the unqualified parts inside the workpiece to make the rest of the workpiece more in line with the requirements. There are many similarities between internal grinder and external grinder, as well as the types of workpieces processed and polishing methods, but the difference is that the positions of polished workpieces are different. The internal grinder grinds the inside of the workpiece, and the external grinder grinds the outside of the workpiece. In the internal grinder, except its principle and operation are different from other grinders, its fault maintenance methods and maintenance emphasis are also different.

These common problems can't be ignored, and we will always encounter them when we use them in workpiece production, so we must solve them so as not to affect the normal use of the equipment in the future. We can unify the use and operation principles of related equipment and help you introduce the correct use of equipment.

1. Workpiece types suitable for internal grinder grinding

Internal grinder is mainly used for grinding workpieces with internal circular holes and internal conical holes. In real life, such as bearing inner hole, this kind of internal grinder can be used for polishing, which can improve the grinding efficiency and accuracy. It is suitable for grinding various workpieces of air-conditioning compressors, various workpieces in bearing processing industry, various automobile parts, and grinding through holes, blind holes, stepped holes, conical surfaces, end faces, conical holes and spherical surfaces of various high-precision and ultra-high-precision aerospace and ship parts.

2. How to solve the taper problem of internal grinder?

The taper problem of internal grinder shows that the accuracy of the equipment is declining and needs to be adjusted properly. If the internal grinder has taper, it should be adjusted according to the structure of the grinder to eliminate taper. The operator can loosen the fastening screws on the bracket first, and then adjust the grinding tool appropriately.

3, internal grinder grinding blind hole

The blind hole of internal grinder is easy to become sharp, which leads to the decline of grinding accuracy. The main reason for this problem is that the concentricity of the equipment is not good or the workpiece is not clamped well. Operators can find out the cause of the problem from many aspects.
