Description

Technical Field

[0001] The utility model belongs to the technical field of machining, and particularly relates to a special double-sided lapping machine for small workpieces. Background Art

[0002] Machining refers to the process of changing the shape, size or performance of a workpiece through a mechanical device. Compared with manual machining, machining reduces the amount of manual operation. The double-sided lapping machine belongs to the category of machining equipment and is suitable for grinding small workpieces.

[0003] A double-sided lapping machine refers to a high-precision mechanical device specifically used for lapping and polishing two parallel surfaces of a workpiece. The double-sided lapping machine consists of a base plate, an upper lapping plate, a lower lapping plate, a material plate and a driving component. The material is placed on the material plate, and the driving component is controlled to move the upper lapping plate and the material plate to realize the lapping process of the upper and lower end surfaces of the material.

[0004] However, it still has the following drawbacks in actual use:

[0005] For the existing double-sided lapping machine, during use, when the driving component is started, the gear disk on the lower lapping plate rotates around its own axis while revolving, so as to realize the grinding of the lower end surface of the small workpiece on the gear disk. However, it is not convenient to filter and recycle the cleaning liquid or coolant, resulting in the waste of the cleaning liquid or coolant because they cannot be recycled.

[0006] 2. For the existing double-sided lapping machine, during use, when the driving component is started, the upper lapping plate grinds the upper end surface of the small workpiece, and the small workpiece is sprayed with water by a flushing component. However, the cooling effect on the small workpiece is poor, which will have an adverse effect on the small workpiece due to high temperature and reduce the quality of the small workpiece during grinding.

[0007] Therefore, we provide a special double-sided lapping machine for small workpieces to solve the above problems. Summary of the Utility Model
