Grinding Wheel Dressing on the Roughness of Workpiece Surface

It is confirmed from years of industry experience that metal polishing materials grinding wheel dressing on the roughness of workpiece surface can start with the selection of technology and polishing materials and other aspects.

First of all, the technical analysis from polishing material grinding wheel:

A. If grinding wheel can not meet the roughness in dressing the roughness of the workpiece, you can try to increase the speed of grinding wheel within the scope of the grinding wheel speed, to increase the surface roughness of the workpiece. From the other hand, you can also try to decrease the speed of grinding workpiece. The aim is to increase the relative speed of grinding wheel and workpieces.

B.  If the effect is not ideal by using the first method, you can also reduce the longitudinal feed of workpieces to reduce the strength of grinding wheel and bows and arrows, which can also prevent the large area burn of workpieces.

C. The flow of cutting fluid and coolant also need to be controlled in the working process, and it is important to change clean cutting fluid and coolant in order to reduce the likelihood of debris jam grinding wheel blowhole.

D. If the above several conditions have been improved, the pattern of the workpiece still can not meet the requirements for the roughness of the workpiece, then it need to adjust the grinding wheel balance precision, rotation accuracy of grinding spindle and the running smoothness of the workbench. The stiffness of the machine tool and the entire process system and the vibration of cutting grinding also need to be checked or adjusted.

Secondly, the selection from polishing material grinding wheel:

Generally speaking, we should choose the appropriate grinding wheel to grind the grinding wheel workpiece. Abrasive that has an affinity with the workpiece materials should be selected: If the workpiece materials are soft and sticky, you should choose hard abrasive products; If they are hard and brittle, you should choose softer abrasive products.

If you choose to use a grinding wheel whose diameter is larger, you can increase the width of grinding wheel. If the granularity of grinding wheel is fine, it can reduce the roughness values on the workpiece surface.

Finally, from the aspects of grinding wheel dressing diamond pen:

In the process of grinding wheel dressing workpieces, the diamond pen with good wear resistance and suitable blade shape and installation angle can make the abrasive cutting edge obtain good contour and lower surface roughness according to the scientific and reasonable grinding technology.
