As with any electrical appliance, a certain amount of heat will be produced by an angle grinder while it is in use. However, if it gets too hot to comfortably hold, this should be taken as a sign of a fault. If the heat has come about after using the appliance for a significant period of time, turn off the appliance and rest it for a while.
Creep feed grinding is a slow, one-pass operation that makes a deep cut of up to one inch in steel materials at low table speeds between 0.5 and 1 ipm. It is not suitable for conventional grinding machines, but for those which are compatible with it, it offers high productivity and cost effectiveness.
If impossible to change machine location, mount grinder on some vibration insulating material. Be certain insulation is thick enough to be effective. If it is not sufficient, the natural. frequency of grinder normally damped out by rigid construction may be emphasised and combine with external vibration to make conditions worse.
