Various faults that could be encountered during grinding and various solutions to overcome them are given below: (c) Reducing rate of traverse and work speed, and slightly decreasing the depth of cut. Grinding wheels have self-sharpening properties due to releasing of dulled grains and exposing new sharp ones. Due to greater forces on them during machining, they either fracture to present new sharp cutting edge, or get lodged out and new grains below it become exposed and take part in material removal. You’ll want to adapt this template a bit to reflect the style of language your company uses. : Your letter dated . In that case, grinding ratio is equal to the ratio of the amount of material ground per amount of wheel wear and the product of specific grinding power and surface finish on test piece. Wheel loading occurs when workpiece chips are embedded in the cutting face of the wheel, thereby reducing the rate of cutting because the depth of penetration is reduced. Nowadays, grinding is mainly used for the following purposes: (i) To remove a very small amount of metal from the workpiece to bring its dimensions within very close tolerances after all the rough finishing and heat treatment operations have been carried out. To grind means ‘to abrade’, to wear away by ‘friction’ or ‘to sharpen’. January 11, 2021. Average volume of one chip = f(1/6) wmax tmax l.
