Working Principle Of Grinding Using Electrolytic In Process Dressing

Grinding is machining process where material is removed by the action of abrasive particles whereas Electrolytic-in-process-dressing grinding (ELID Grinding) is an in-situ dressing method used for metal-bond wheels. This technique being greatly successful for fine grain wheels to obtain high surface finish of higher order and for the machining of hard ceramics by applying a small cutting depth

Jun 01, 2002 Fig. 2 shows the mechanism of ELID grinding for a metal-bonded diamond wheel. After truing [], the grains and bonding material of the wheel surface are flattened.It is necessary for the trued wheel to be electrically pre-dressed to protrude the grains on the wheel surface. When pre-dressing starts [], the bonding material flows out from the grinding wheel and an insulating layer composed of

Dec 09, 2012 These unconventional conditioning processes may take place on the working surface of the abrasive tool, simultaneously with the grinding process, thus combining in-process truing and dressing. Electrolytic in-process dressing conditioning, mentioned previously, has been particularly successful in increasing productivity and quality when using

Electrolytic In-Process Dressing (ELID) is a relatively new but quite efficient technology especially serves this area. Benefiting from electrolysis effect, ELID continuously maintains an oxide layer on grinding wheel which can considerably reduce normal grinding force. This In-Process dressing eliminates redundant wheel dressing so as to

The Electrolytic In-process Dressing (ELID) is a new technique that is used for dressing harder metal-bonded superabrasive grinding wheels while performing grinding. Though the application of ELID eliminates the wheel loading problems, it makes grinding as a hybrid process. The ELID grinding process is the combination of an electrolytic process

Aug 12, 2017 Electrolytic In-Process Dressing (ELID-) grinding is a method for grinding hard and difficult to machine materials, such as ceramics in mirror surface quality. This is possible due to the chip absorbing ability of the generated oxide layer during electrolysis and the self-controlled sharpening process that results from a combination of preprocess dressing and in-process dressing of conductive grinding wheels whilst grinding
