The balance of grinding wheel

The balance of grinding wheel
Install wheel on the grinder should pay particular attention. Because the wheel at high speed working conditions, should be carefully examined before use, does not allow cracks. Installation must be firm and should be static balance adjustment in order to avoid personal and quality accidents.
Between the wheel and the wheel shaft or bore cylindrical flange, not too tight, otherwise the thermal expansion of grinding, grinding wheel easy to bursting, not too loose, otherwise prone to eccentric wheel, loss of balance, so as to cause vibration. Usually with the gap of 0.1 ~ 0.8mm, high-speed grinding wheel gap to be smaller. When the wheel clamping flange with two flange diameter should be equal to the outer diameter shall be not less than 1/3 of the outer diameter of the wheel. Application between the flange and the end face of the grinding wheel cardboard or oil and rubber gaskets and so do the pressure evenly distributed, the tightening force of the nut can not be too large, otherwise the wheel will break. Note that the fastening screw rotation, and the wheel should spin to the contrary, that is, when the wheel is rotated counterclockwise, with right-hand thread, so that the grinding wheel under the force will drive the screw nut more tightly.
