Fine finishing of almost all kinds of hard and brittle materials, ranging from hardened steels, BK7 glass, mono-crystalline silicon, silicon carbide, aluminum nitride, silicon nitride etc, has been successfully carried out, to provide high quality surfaces with low sub-surface damage.

A Review of Electrolytic In-Process Dressing (ELID) Grinding | Indraneel Biswas –

Cheng Zu Ren, X. The procedure furthermore allows grinding wheels with extremely fine granules to be used ca. Eld, fine grinding of sapphire is quite challenging because of its high hardness and low fracture toughness, making it sensitive to cracking.

Qing Liang Zhao, D. A gist of the important research milestones on the process has been organized in this report. ELID Grinding, since its introduction over two decades ago, has helped in material removal of hard and difficult-to-cut engineering materials.

More from this author Optimum cutting conditions for new materials Is 3D printing something for your company? However, the differences of material performances cause the granite materials to be larger e,id grain depth of cut and more ductile during finely grinding.


The wheel wear mechanism in ELID grinding of sapphire was dominated by bond fracture because the bond strength is reduced by electrolysis. You do not have access eid this content.

The metalworking sector also benefits from AM Herlou Groep develops ergonomic PVC window profile handling tool Precision milling of a compression mould.

Correlations were found among the dressing current intensity, surface finish and acoustic emission signals.

Moreover, ELID grinding allows a work piece with good geometrical accuracy in combination with a highly smooth surface to be obtained, making a polishing stage redundant. Wang, Ying Chun Liang. This phenomenon may be one of the main reasons that subsurface damage is reduced on ultrasonic grinding.

ELID grinding characteristics of large stamping die for Wolter mirror.

The simulation result shows that, the uniform height of the abrasives in the contour of the grinding wheel is improved owing to the existence of passivation film in ELID grinding, it is related to the thickness grunding the passivation film, and processing quality in ELID grinding could be enhanced through controlling of thickness of the passivation film.

Historical Development of the Windmill. Different variants of the process have also been reported, though the basic philosophy of operation is the same as basic ELID.

Thin Solid Films, Vol. This grinding technique allows metal-bound grinding discs to be used, which are after all highly durable and difficult to adjust compared with discs with slid or glass. So cracks can not expand to material deep and shallow sub-surface cracks are left in workpiece sub-surface layer. For assistance or to subscribe, please contact us:. A smoother surface was obtained using a higher dressing current at the cost of a higher wheel wear rate.
