Install the wheel on the grinder should?

Wheel is working at high speed, then fly or easily spill caused no casualties. So be especially careful before using checks, does not allow cracks. The installation must be reliable, and to go through static balance adjustment, so it will not cause injury.
Between the wheel and the wheel shaft or bore cylindrical flange, not too tight, otherwise the grinding thermal expansion, easy to wheel 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 wheel diameter. Application of the end surface between the flange and the wheel cardboard or oil and rubber, and so do the pad, the pressure evenly distributed, the tightening force of the nut can not be too large, otherwise the wheel will break. Note the tightening screw rotation, and the wheel should spin in the opposite, that is, when the wheel is rotated counterclockwise, with right-hand thread, so that the diamond reinforced concrete in force, will drive the screw nut more tightly.
