Slotted Tools

Slotted tools or so-called segmented tools consist of a discontinuous abrasive layer either with geometrically defined or undefined cavities [KIRC10, p. 9]. Grooves can be perpendicular to the wheel perimeter or inclined.

The so-called T-Tool wheel consists of a metal bonded, segmented superabra­sive layer and can significantly reduce forces and temperatures in SiC grinding compared to the process with a non-segmented wheel [TAWA11]. Kirchgatter [KIRC10] examined several different designs for slotted grinding tool in outer diameter grinding applications. He highlighted that improper slot design can lead to dynamical problems in the grinding process, but proved a lower thermal damage of the workpiece. Slotted wheels allow for reduced cooling lubricant flow [UHLM10].

9.2.2.2 Controlled Abrasive Clusters

Yuan et al. [YUAH10] invented an electroplated tool with controlled abrasive clusters (CAC) and used it successfully to grind carbon/epoxy composites with reduced wheel loading. The use of covers during the electroplating process allows the control of shape and pattern of superabrasive grit clusters.
