Analysis of the causes of poor grinding of plane-parallel grinding machine and countermeasures.

The plane-parallel grinding machine plays a vital role in the machining industry, which is mainly used for grinding the parallel and vertical surfaces of the workpiece. However, in the actual use process, the operator may encounter the problem of poor grinding, which not only affects the processing quality of the workpiece, but also may lead to a decrease in production efficiency.

First. The common causes of poor grinding

1. Grinding wheel problem: uneven grinding wheel wear, improper particle size selection or hardness mismatch may lead to poor grinding.

2. Grinding fluid problem: The concentration and type of grinding fluid are not selected properly or not replaced in time, which may affect the grinding effect.

3. Workpiece clamping problem: workpiece clamping is not strong or improper clamping method, which may lead to vibration and displacement during grinding.

4 grinder parameter setting problems: such as grinding speed, feed, grinding depth and other parameters are set unreasonable, will also affect the grinding effect.

5. Environmental factors: changes in environmental factors such as temperature and humidity may also affect the grinding effect.

Second. Coping methods

1. For the grinding wheel problem: check the wear of the grinding wheel regularly and replace the new grinding wheel in time; Select the appropriate grinding wheel size and hardness according to the workpiece material and processing requirements.

2. For the problem of grinding fluid: select the appropriate type and concentration of grinding fluid according to the material and processing requirements of the workpiece; Replace the abrasive fluid regularly to avoid contamination and failure.

3. For the workpiece clamping problem: improve the workpiece clamping method to ensure that the workpiece clamping is firm and stable; For the workpiece with special shape, special fixture can be designed to improve the clamping accuracy.

4. For the problem of grinding machine parameter setting: according to the workpiece material, processing requirements and grinding wheel performance and other factors, reasonable setting of grinding speed, feed, grinding depth and other parameters; Regular maintenance and maintenance of the grinding machine to ensure that it is in the best working condition.

5. For environmental factors: control the temperature and humidity of the processing workshop within a reasonable range to avoid the impact of environmental factors on the grinding effect.

Third. Summary and Suggestions

There are many reasons for poor grinding of plane-parallel grinding machine, which requires the operator to accumulate experience and summarize in actual operation. The problem of poor grinding can be effectively solved by selecting grinding wheel and grinding fluid reasonably, improving workpiece clamping mode, optimizing grinding machine parameter setting and controlling environmental factors. At the same time, it is recommended that enterprises increase investment in staff training, equipment maintenance and process optimization to improve the processing quality and production efficiency of the plane-parallel grinding machine.
