Example Embodiment
[0014] Example one:
[0015] Such as figure 1 As shown, the present invention is an ultrasonic vibration micro-EDM workbench based on a micro-EDM machine tool, which includes a pre-tension spring 4, a piezoelectric ceramic 5, a machine tool base 6, a power supply 7, an adjusting resistor 8, a piezoelectric Actuator housing 9, push rod 10, working fluid tank 11. When the quality of the processed workpiece 3 is small, the dynamic follow effect is better. The ultra-sonic vibration micro-EDM workbench can adopt high-frequency ultrasonic vibration, the frequency range is 38KHz-42KHZ, and the processed workpiece is fixed in the working fluid tank 5 with bolts. And immersed in the working fluid, the processing effect is better. The number of laminated piezoelectric ceramics 5 is three. The piezoelectric actuator housing 9 functions to protect the piezoelectric ceramic 5 and is made of corrosion-resistant stainless steel. The specific dimensions are determined according to the dimensio...
Example Embodiment
[0020] Embodiment two:
[0021] Such as figure 1 As shown, when the rough machining is performed, the number of laminated piezoelectric ceramics 5 is five in order to obtain greater machining efficiency. Others are the same as in Example 1.
Example Embodiment
[0022] Embodiment three:
[0023] Such as figure 1 As shown, when the size of the processed workpiece 3 is small, mechanical fixation is difficult. The processed workpiece 3 is fixed in the working fluid tank 5 by adhesive bonding and immersed in the working fluid. After the processing is completed, the workpiece is removed by dissolving in an organic solvent. Others are the same as in Example 1.
