Description

technical field

[0001] The invention relates to the technical field of auxiliary accessories for numerical control machining, and in detail is an automatic grinding fixture for numerical control machine tools with simple structure, high degree of automation, convenient use, high positioning and repeat positioning accuracy, reduced labor intensity and high production efficiency. Background technique

[0002] Currently, grinding or grooving of workpieces is usually accomplished by manual clamping close to the grinding wheel. During the grinding process, repeated measurements are required to ensure the processing requirements. This method not only increases the labor intensity of the staff, but also depends on the experience of the staff to determine the amount of grinding during the grinding process, thereby reducing the accuracy of clamping positioning and repeated positioning, and it is difficult to maintain the consistency of multiple workpieces. , and reduce the processin...
