Hoffmann Group 47 Form UiSiiY Ceramic bonded external cylindrical grinding wheels High performance external cylindrical grinding wheels in ceramic bonding. The grinding wheel structure incorporates the optimum match of grit volume and bonding volume; bonding strength and manufacturing process are characterised by: High cutting effectiveness and reduced grinding times with low wear, Low thermal loading, cool cutti ng. Long cycles between dressing operations mean reduced downtime. 594125-4565 - Specification: 89A 80J5 AV217. Aluminium oxide for general purpose use. 594590/4595 - Specification: 454A 80J10 V3. Sintered aluminium oxide for longer working life and better metal removal rate. Particularly suitable for high alloy steels / HSS. Application: For general use in external cylindrical grinding (straight/ oblique longitudinal grinding, recess grinding). For use on all grinding machines generally used for tool and die making, and machine tool building (e.g. Kellenberger,Studer,Schaudt,Tschudin,etc.) Cooling with emulsion is necessary, good lubrication on long-chipping materials is absolutely necessary.
