Cause analysis and countermeasures of surface grinding and scratch of double disc grinding machine

The double disc grinding machine is one of the commonly used equipment in machining, which is mainly used to process the workpiece made of various metal materials. However, when using a grinder for processing, there are sometimes problems with surface grinding and scratches. These problems will not only affect the surface quality of the workpiece, but also may lead to the scrap of the workpiece, bringing great losses to production. Therefore, it is very important to understand the causes of surface grinding and scratches and take corresponding measures.

First, the feeding guide is worn and uneven, resulting in uneven feeding

During the double disc grinding machine process, the workpiece needs to be sent between the grinding wheel and the guide wheel for grinding. If the feeding guide is worn and not straight, it will cause the workpiece to be offset during feeding, which will make the grinding force uneven, and eventually lead to surface grinding and scratching. Therefore, when using the machine, it is necessary to regularly check the wear of the feeding guide, and timely replace the seriously worn guide to ensure the stability of the workpiece during feeding.

Second, the guide plate is not parallel to the grinding wheel face

The guide plate and the grinding wheel of the equipment work together. If the guide plate is not parallel to the grinding wheel face, it will lead to uneven forces on the workpiece during grinding, resulting in plane grinding and scratches. Therefore, when adjusting the grinder, it is necessary to ensure the parallelism of the guide plate and the working surface of the grinding wheel, so that the workpiece is evenly stressed during the grinding process.

Third, the end face of the grinding wheel is too small, so that the outer edge of the grinding wheel bears most of the cutting amount, resulting in the grinding wheel becoming dull

The grinding wheel of the grinder is the main cutting tool. If the end inlet of the grinding wheel is too small, it will make the outer edge of the grinding wheel bear most of the cutting amount, resulting in the grinding wheel becoming dull, which affects the grinding effect, resulting in plane grinding and scratches. Therefore, when selecting the grinding wheel, the appropriate grinding wheel model and specification should be selected according to the material and processing requirements of the workpiece.

4. The distance between the baffle plate and the guide plate is too large or too small, resulting in poor ring positioning or large workpiece movement resistance

The distance between the inlet and outlet baffle of the double disc grinding machine and the guide plate has an important influence on the positioning and movement of the workpiece. If the distance is too large or too small, it will lead to poor ring positioning or workpiece movement resistance, thereby affecting the grinding effect, resulting in plane wear and scratches. Therefore, when using the grinder, the distance between the apron and the guide plate should be adjusted according to the size of the workpiece and the processing requirements to ensure the stability and processing accuracy of the workpiece.

In short, the causes of surface grinding and scratching are many. In order to reduce the impact of these problems on production, we need to regularly check and maintain the equipment to ensure the normal operation of the equipment and the processing quality of the workpiece. At the same time, we also need to continuously improve our skill level and understanding of the equipment to better cope with various problems and improve production efficiency.
