“…1,2 Electrical discharge machining/dressing (EDM/EDD) has the advantages of simplicity, no contaminant generation and no contact between the grinding wheel and the tool electrode, but the grinding grain distributed on the surface of the diamond grinding wheel is insulated, which affects the electric spark discharge process and the overall dressing effect. 3 Although the laser dressing overcome the problem in mechanical finishing, the higher investment and requirement for environment and protection was not avoided. 4,5 Electrolytic in-process dressing (ELID) is particularly suitable for precision grinding of metal binders, ultrafine granularity and ultra-hard grinding wheels, which solves the problem of continuous sharpness of metal ultrafine ultra-hard grinding wheels, but it is less efficient.…”

A high-precision continuous dressing technology, namely ultrasound-aided electrolytic in-process dressing method, was proposed in this paper, aiming at overcoming the difficulty in continuous dressing for fine diamond wheel during the super mirror processing, such as optics and aeronautics. Firstly, the influence of high-frequency ultrasonic vibration on electrolysis was analyzed on the basis of the mechanism of electrolysis. Then, the compared tests between the common electrolytic in-process dressing grinding and the ultrasound-aided electrolytic in-process dressing grinding of the grinding wheel were employed to observe the effect of dressing and the state of abrasive particle. It was found experimentally that under the latter dressing, the better dressing effect could be gained, and the number of abrasive particle per unit area, the sharpness of abrasive and the average grain protrude height were improved; meanwhile, the distribution of grains become more uniform. In addition, compared with the former dressing, the average distance between grains was decreased, and the microscopic roughness of grinding wheel physiognomy was increased in the latter dressing. Finally, the grinding experiment was carried out to illustrate the advantages of the ultrasound-aided electrolytic in-process dressing grinding. The experimental results revealed that the removal rate and machining surface quality were increased compared with the common electrolytic in-process dressing grinding.

“…However, it is di cult to precisely trim. EDM dressing is a non-contact dressing method for grinding wheel, which greatly changes the shortcomings of "hard contact" in the traditional mechanical dressing, it has the characteristics of high precision, high e ciency and low cost, and is widely used in the dressing of metal-bonded diamond wheel [4][5][6][7][8] . Graphite and brass were used as discharge electrodes in dressing experiments respectively.…”

Electrical discharge dressing has advantages of high precision, high e ciency and low cost, which is an effective dressing method for metal bonded diamond grinding wheel. In this paper, the in uence of discharge voltage, discharge current and power pulse width on the surface morphology of the grinding wheel were studied by single factor method. The grinding experiments of SiC ceramics were carried out and the surface morphology of the grinding wheel and the surface roughness of the workpiece after grinding a certain volume of SiC ceramics were analyzed. The experimental results show that large electrical parameters can improve the dressing e ciency, but the grinding wheel surface appears more adverse phenomena such as abrasive shedding, looseness, bond melting recasting. In the early stage of grinding wheel, surface damage is serious, and grinding workpiece surface roughness is poor. It provides a practical reference for the reasonable selection of EDM dressing of metal bond diamond grinding wheel.
