Grinding tool capable of sensing grinding state and grinding system including same

The invention relates to a grinding tool and a grinding system comprising it.

Abrasive tools generally use bonding agents to consolidate abrasives into different shapes, so as to be widely used in grinding, cutting, polishing and other processing of workpieces. With the diversified development of the precision machinery industry and the semiconductor industry, each component requires higher and higher precision and production speed, so the specifications of grinding tools are becoming more and more complicated. In addition, in order to keep the grinding tool in a good grinding state during processing, those skilled in the art know that the grinding tool needs to be trimmed. Therefore, when and what dressing conditions must be used for the grinding tool is also an important key technology. However, since the surface morphology of the grinding tool is constantly changing, it is necessary to rely on experienced operators to constantly check the state of the grinding tool during the grinding process in order to ensure stable and good grinding quality.

In order to try to solve the above problems, the Republic of China Invention Patent No. I722478 provides a method for optimizing the grinding wheel processing map. It uses the controller of the grinding machine to first obtain the reference processing map of the grinding wheel from the data platform, and then uses the optimization included in the controller. The module operation generates a magnification value to form an optimized processing map. Although the aforementioned method can reduce the reliance on the operator's experience, the original problem still exists when using a grinding wheel without a ready-made reference processing map, and even with an optimized processing map, the operator still needs to frequently interrupt the grinding process. To confirm the current state of the grinding tool.

In addition, the Republic of China Invention Patent No. I624741 provides an intelligent grinding machine equipment for automatic detection and grinding. It first uses an intelligent encoder to edit the overall processing sequence or parameter setting program of the processing system, and then grinds on the surface grinder. The unit is equipped with a grinding detection unit, so it can automatically detect the overall appearance of various workpieces during the processing process. When the grinding wheel unit performs plane grinding on the workpiece, the load force and cutting force parameters generated by the grinding wheel unit reach a predetermined parameter. , the smart encoder will automatically execute the edited sequence or parameter setting program and transmit instructions to control the overall operation of the surface grinder to generate an optimal grinding path, thereby shortening the grinding stroke distance and improving processing efficiency. However, if you want to use this technology, you can only purchase expensive specific grinding equipment, which cannot effectively reduce the manufacturing cost; in addition, because the grinding detection unit is installed in the surface grinder, it can only obtain processing signals indirectly and cannot be widely used. various technical fields.
