Aug 26, 2017· As a relatively newgrindingtechnology,ELID(electrolytic in-process dressing) is widely used in some businesses. The oxide layer plays an important role inELID grindingperformance. The purpose of this work is to investigate the state of the oxide layer onELID grindingwheel surfaces based on workpiece-cathode and tool-cathode. The thickness and surface topography of the oxide layer were ...Get Price
TheELID-grindingmethod is applied to wide ranges of practical uses in precision manufacturing. As shown in the figure, the conductive wheel (metal bond) serves as the positive electrode, and the negative electrode is installed opposite to thegrindingsurface of the wheel. The clearance between these two electrodes is set at 0.1 to 0.3 mm. D ...Get Price
ForELID grindingthe interaction between the abrasive grain and the workpiece surface is modeled by a spring-damper system (because of the existence of the oxide layer), while for rotary dressing the contact is rigid and stiff. ... 19.6Summary.

ELID. ELID grinding produces good surface characteristics on CVD -SiC films. Tools finished with ELID have wear rates that are less dependent upon the lay of surface finishes. Also wear is minimal when contract pressures are below a critical maximum value, which is coincident with a transition from powder to nonpowder wear mechanisms.Get Price
Covering methods that offer high-rate material removal and others that provide extremely high-quality surface finish, this book examines conventional, new, and lesser-known methods including ductile grinding, belt centerless grinding, lapping, polishing, double-side grinding, laser-assisted grinding, ultrasonic machining, and the new electrolytic in-process dressing (ELID) grinding method.Get Price
