Description

Technical Field

[0001] The utility model relates to the technical field of ultrasonic electric spark dressing, in particular to a device for powering a disc electrode. Background Art

[0002] Electrospark dressing can solve the shortcomings of traditional mechanical dressing, such as low dressing efficiency and poor precision, and obtain a grinding wheel with high sharpness and high shape precision to meet the processing requirements of complex surface hard and brittle materials such as free-form surfaces. In ultrasonic electrospark dressing, the disk electrode rotates continuously during the processing, and the electrode loss will be evenly distributed on the circumference of the electrode. It will not wear in one direction all the time like traditional electrospark machining, which fully extends the service life of the electrode.

[0003] At present, in the relevant technology, the size of electrical parameters has a great influence on the material removal efficiency and surface morphology of the grinding wheel during ultrasonic electric spark dressing. Therefore, continuous power supply to the electrode has become a key issue in the electric spark dressing process. The existing methods of continuous power supply to the electrode are mostly to connect the power supply to the electrode surface or edge through the electrode frame using wires or cables, and supply power through wire contact. However, this method may result in continuous power supply or unstable electrical transmission. Utility Model Content
