The bonding system with highly porous structures made of selected premier quality grit offers these advantages Reduced thermal loading. Minimal dressing diamond wear. Universally applicable for pendular grinding processes, which significantly reduces the frequency of wheel changes in daily operation. Can be used on all commercially available grinding machines for tool and die making and machine tool building (e.g. Jung, ABA, Blohm, Elb, Magerle, Ziersch&Baltrusch, Geibel&Hotz, Jones&Shipman.) Cooling with emulsion is necessary, ensure good lubrication, especially on long-chipping materials. t Shape 1 , , Shape5 If Ti Note Profile surface grinding wheels available on request. tF iiiii + t Shape7 , i, Suitable for/ vc m/s AlMg <900 N <1400 N <55 HRC <60 HRC <67 HRC Carbide INOX Ti GG G) CuZn Plastics &GRP Wood Stone Varnish Uni -TT1 max 59 0150-0670 - 59 1106-1666- 0 59 2400-2620- 59 2760-2765- 0 0 Surface grinding wheel for unalloyed and low alloy unhardened steels Version Specially treated Aluminium Oxide for grinding unalloyed and low alloy unhardened steels. 590420/0670- Form 7 with recesses on both sides. 590560/0640- Form 5 with recess on one side.
