AI Technical Summary
The existing chuck structure design of the grooved wheel in multi-wire EDM machines results in insufficient positioning accuracy, making it difficult to meet the requirements of high-precision machining. This leads to a large deviation in the coaxiality between the grooved wheel and the machine tool spindle, affecting machining efficiency and product quality.
The system adopts a combination structure of positioning seat and positioning element. The positioning seat is coaxially mounted on the lathe spindle, and the first and second positioning elements clamp the grooved wheel from both ends to achieve coaxial positioning of the grooved wheel, thereby enhancing clamping stability and accuracy.
It improves the positioning accuracy of the grooved wheel, reduces machining vibration, enhances the dimensional accuracy and surface finish of the groove, extends tool life, and improves machining efficiency and product qualification rate.
