Maintenance of grinder suction cup

 At present, the honing head of honing machine is mainly made of inlay technology. After finishing the surface of machined parts, the machining aperture will become 5-500mm.

For large cylindrical hole, valve hole, cylinder, box hole, connecting rod hole, etc., the proportion of aperture and hole depth can be about 10, or larger. 

Under relative conditions, honing can also be processed For example, the surface roughness of cylindrical honing teeth is mostly different. When honing, it can reach ra0.04 microns or less. The machining accuracy is about it7-4. For some Plane Honing teeth, the surface quality may be slightly worse.

The surface of permanent magnetic casting chuck or electromagnetic chuck is the basis of whether the grinding accuracy of the workpiece can meet the requirements, and it should be maintained from time to time.

If the accuracy of the work object is not up to the standard or the disk surface is damaged, the disk surface needs to be ground again, and the accuracy of the disk surface has been asked to meet the requirements, so as to ensure the grinding accuracy of the workpiece.
