Grinding wheel processing device control system and method

The invention relates to a control system and method for a grinding wheel processing device, in particular to a working mode of a grinding wheel processing device.

In the application of precision grinding machines, the maintenance of the precision of the grinding wheel plays a very important role. For the grinding of the grinding wheel, in addition to the sharpness of the grinding wheel surface, the size of the contour of the grinding wheel must be kept accurate before the grinding machine can be used. When machining with a grinding wheel, a finished product of good quality is obtained.

However, after the grinding wheel is ground for a long time, the grinding wheel itself will wear and need to be trimmed frequently. For grinding machines, dressing the grinding wheel is a necessary and repetitive task. In general, when grinding a wheel or a dressing wheel using a grinding machine, the processing tool 91 is controlled to be machined or trimmed along the contour 92 of the article or dresser 93 in a single direction, and as shown in Fig. 1, in order to avoid processing The single grinding amount of the appliance 91 is too large, causing the processing tool 91 to be damaged, and most of the way, the delamination grinding along the contour 92 is adopted. In this manner, in addition to having to move along the same contour 92 in each layer of processing, since the processing tool 91 will only be processed in a single direction along the contour 92, long-term use will cause severe wear on one side of the processing tool 91, which must be The processing tool 91 is removed by the grinding machine mechanism, and the processing tool 91 is re-processed on the other side that has not been seriously worn out. Otherwise, if it is directly replaced, it will inevitably result in unnecessary waste of materials and assembly and disassembly mechanism time. Consumption, under the characteristics of the grinding machine industry, which is aimed at high-speed production, this will undoubtedly seriously drag down production efficiency and lead to a decline in corporate profits. On the other hand, when other paths are to be used for processing, users need to make complicated modifications and readjustments.
