Effective strategy to solve common problems of double end grinding machine

When using a double-end grinding machine for processing, some common problems are often encountered. The following describes and provides effective strategies to address these issues.

1. Grinding burn:

Grinding burn is a problem caused by heat generated during grinding. The key factors are the grinding speed, the cooling effect of the grinding fluid and the load between the grinding wheel and the workpiece. Solutions include adjusting the grinding speed, choosing a more suitable grinding fluid to provide adequate cooling, and ensuring appropriate wheel and workpiece loads. In addition, the grinding wheel is lubricated and trimmed regularly to ensure its grinding performance.

2. Taper of parts:

The taper of a part refers to the inclination of the position in the plane of the workpiece. The cause of this problem may be the position of the grinding head or the uneven grinding width of the grinding wheel. The solution is to ensure the accuracy of the position of the grinding head, use a grinding wheel of uniform width, and correct the taper of the part by adjusting the grinding parameters and the clamping force of the workpiece.

3. Grinding edges:

Grinding edge collapse is the material displacement or deformation generated during the grinding of the workpiece edge area. It may be caused by excessive grinding pressure or the grinding wheel grinding width is not matched. The solution is to adjust the grinding parameters, such as reducing the grinding pressure, to ensure that the width of the grinding wheel ADAPTS to the workpiece, in order to reduce the generation of grinding edges.

4. Smoothness:

The smoothness of the workpiece is the key index to evaluate the grinding quality. If the workpiece surface roughness is too high, it may be caused by grinding wheel wear, insufficient grinding fluid or improper grinding parameters. Solutions include regular inspection and replacement of grinding wheels, ensuring adequate supply of grinding fluid, and adjusting grinding parameters as needed to obtain the desired level of smoothness.

5. Workpiece thickness deviation:

The workpiece thickness deviation may be caused by the deformation of the workpiece during grinding or the uneven initial thickness. Solutions include ensuring the accuracy of workpiece clamping and positioning, optimizing grinding parameters to reduce workpiece deformation, and adequately pretreating the workpiece before grinding to improve initial thickness uniformity.

By adopting the above strategy, the common problems of the double-end grinding machine can be effectively solved, the processing quality and efficiency can be improved, and the workpiece can meet the required requirements.
