To meet the requirement of heavy dressing, Multipoint Diamond Tools are used. Fine Quality Octahedronal Diamonds are set in a distinguished pattern, where height of all the diamonds are maintained within a close tolerance to achieve superior finish and efficient dressing.
The main features which distinguishes this type of tool from Single Point Dresser is that the contact area between the tool and the wheel is divided into several parts.
Each Diamond takes a proportion of the infeed. If we consider 5 diamonds with an infeed of 20 microns the individual diamond contributes only to an extent corresponding to 4 microns. This greatly improves the performance of the diamond to stretch life span, it proved to be economical. |
