In the machining process of CNC surface grinding machine, it is a common problem to encounter the trace of drawing on the workpiece surface, but it needs to be solved in time. Here are some effective solutions:

First of all, checking the state of the grinding wheel is key. Brushed marks are often caused by uneven wear of the grinding wheel or by the loss of abrasive particles. Therefore, the grinding wheel should be checked and trimmed regularly to ensure that it is sharp and has a smooth surface. If it is found that the grinding wheel is seriously worn or has raised abrasive particles, it should be replaced or re-trimmed in time.

Secondly, optimizing grinding parameters is also an important method to solve the drawing marks. Including adjusting the grinding speed, feed rate and grinding depth and other parameters to ensure that the cutting force in the grinding process is reasonably distributed to reduce the damage to the workpiece surface. Especially in the grinding stage, the grinding allowance should be appropriately increased to ensure that the traces left by the rough grinding are ground away.

In addition, the use of grinding fluid can not be ignored. The grinding fluid can not only cool the grinding wheel and the workpiece, but also play the role of cleaning and lubrication. If the grinding fluid contains impurities or abrasive particles, it should be replaced or filtered in time to maintain the cleanliness of the grinding fluid.

At the same time, choosing the right grinding wheel for the material characteristics is also the key. For materials with greater toughness, a grinding wheel with moderate hardness and finer particle size should be selected to reduce the generation of hair marks.

Finally, regular maintenance and maintenance of CNC surface grinding machine is also an important measure to prevent hair traces. Including cleaning the grinding chips of each part of the machine tool, oil anti-rust, check whether the transmission system is loose, etc., to ensure that the machine tool is in good working condition.

In summary, when there are traces on the surface of the CNC surface grinding machine, it should be started from many aspects such as grinding wheel status, grinding parameters, grinding fluid use, grinding wheel selection and machine tool maintenance to ensure processing quality and efficiency.
