Description

Technical Field

[0001] The utility model relates to the technical field of spindle grinding, in particular to a surface grinding device for spindle processing. Background Art

[0002] In the field of machining, surface grinding is a common process used to improve the surface finish and precision of workpieces.

[0003] The main axis refers to the axis that receives power from the engine or motor and transmits it to other parts. The main axis is also called the optical axis, which is the abbreviation of the main optical axis. It has a symmetrical diameter in the optical system. For example, the main axis of a spherical mirror is a straight line passing through the center of the mirror and perpendicular to the mirror surface. The main axis of a lens or optical axis optical system is the line connecting the centers of the lens surfaces.

[0004] However, during the grinding process of the spindle, the surface of the spindle is often grinded with the help of a single grinding wheel to improve the surface finish and precision. However, during the operation of the grinding wheel, because it is a single-position grinding operation, it is easy to cause over-grinding or under-grinding due to wear of the grinding wheel or position deviation, resulting in a large error with the ungrinded position, and then easily causing the spindle to be scrapped due to the error. Therefore, the overall practicality is not high. Utility Model Content
