Its main function is to hold the grains together with varying degrees of ...
عرض المزيدThe standard vitrified bond straight grinding wheels are intended for operation at operating speed of 35 [m/s] (40 and 45 [m/s] depending on the grain size and hardness grade). For resinoid bond, the conventional operating speeds are correspondingly 50 and 63 [m/s].
عرض المزيدGrinding Machine. A grinding is metal cutting operation which is performed by means of a rotating abrasive wheel that acts as a tool.; These are mostly used to finish workpieces which must show a high surface quality, accuracy of shape and dimension. Mostly, it is finishing operation because it removes material in very small size of chips 0.25 – 0.5 mm.
عرض المزيدDuring grinding, the force of the grinding wheel pushes the workpiece into the regulating wheel which operates at a far slower speed than the grinding wheel, and against the support. This is how the workpiece is held in place, by pressing it between the regulating wheel and the grinding wheel.
عرض المزيدAlthough there are two methods of doing a grinding operation, one is wet grinding and the second one is dry grinding. Wet grinding: In wet grinding, during the grinding operation, we sprayed coolant generally water or any coolant to cool the surface so that the longevity of the grinding wheel increases and also we get a fine surface finish.

عرض المزيدExample: Find the metal removal rate for an external grinding operation of 6" diameter shaft with a .001" depth of cut and a 12 in./min. traverse. Removal Rate = 12 x .001 x 6 x 3.14 = .023 in 3 / min. Traverse feed depends upon the width of the wheel being used and the grinding operation being performed.
عرض المزيدGrinding pressure is the rate of in-feed used during a grinding operation; it affects the grade of wheel. A general rule to follow is that as grinding pressures increase harder wheels must be used. George Schneider, Jr., is the author of Cutting Tool Applications, a handbook to machine tool materials, principles, and designs.

عرض المزيدFor surface grinding operations, the process parameters, i.e. the linear feed, the cross feed, and the depth of cut, have a direct influence on the roughness of the ground surface. Higher values of any of them would result in a higher material removal rate, and therefore, a higher rate of generation of thermal energy.

عرض المزيدIn cylindrical grinding operation, the work is mounted between two centres and is rotated. A grinding wheel is mounted on a spindle and revolves at much higher r.p.m. than the work. The work centres are mounted on a table which can traverse at various feeds so that the entire length of the work passes to and fro in front of the wheel.
عرض المزيدPrior to grinding, a number of stages are involved in gear manufacturing: hobbing is a roughing operation which produces a gear profile with stock remaining for a final grinding process (see figure 1). hardening/heat-Treating is a group of processes used to alter the physical, and sometimes chemical, properties of a material.
