A grinding wheel that is dressed with a diamond roller requires a J-grade wheel, whereas a grinding wheel that is dressed using a blade tool requires a slightly harder L-grade grinding wheel. The level of surface roughness required ranges from 0.4 μm R a for finish grinding to 1.4 μm R a for rough grinding of cam profiles and journals.

The perpendicular orientation profile to grinding direction was recorded in order to compare the worn profile wheel and the fresh profile wheel and consequently to obtain the wear gap, as presented in Fig. 3.This measurement was possible due to the fact that the workpiece thickness is lower than the grinding wheel width.

Off–hand grinding or non-precision grinding is where the grinding wheel is applied manually to the work or where the work is applied off-hand to the grinding wheel. Off-hand grinding includes snagging of castings/forging, tool sharpening, weld grinding, cutting off, bench grinding or pedestal grinding applications.

Two grinding wheel specifications were evaluated: a conventional one of ceramic grain and high performance (specification 3NQ80 L10 VS3, hereafter referred only as 3NQ); and a superabrasive one of cBN grain with vitrified binder (JB126 K150 VSS specification). Both grinding wheels were tested with wheel velocity (v s) of 80 m/s.

Grinding is one of the effective manufacturing processes with which to produce highly accurate parts with an ultra-fine surface finish. The tool used to remove materials in grinding is called the grinding wheel. Abrasive grains made of extremely hard materials (alumina, silica, cubic boron nitride, and diamond) having a definite grit size but a random shape are bonded on the circumferential ...

Grinding is a process for making board-shaped workpieces thin (approx. less than 1 mm thick) and flat by using a grinding wheel. The grinding wheel is an abrasive which uses synthetic diamond. Wheel segments (thickness: several millimeters, height: 3 – 5 mm) are arranged along a ring-shaped wheel base. There are various types of grinding ...

It is possible to determine the most affected areas of the wheel profile according to the grinding strategies applied. Based on this information, the most suitable grinding strategies and cutting conditions can be selected in order to reduce the thermal damage and wheel wear. All three grinding strategies could be adopted for crankshaft production.
