Abstract
In a coolant supply apparatus for a grinding machine, a wheel unbalance prevention device is operated within the period from the switching to the closed state of a shut-off valve which is provided on a conduit connecting a coolant supply to a coolant nozzle, to the rotation stop of the grinding wheel and prevents the coolant remaining in a part of the conduit on the downstream side of the shut-off valve and in the coolant nozzle, from dropping on the grinding surface of the grinding wheel during the rotation stop of the grinding wheel. Thus, it can be prevented that the coolant locally penetrates into the grinding wheel to put the same out of balance.
Claims8
A coolant supply apparatus for a grinding machine having a grinding wheel attached to a wheel spindle rotatably supported by a wheel head, a coolant supply nozzle connected to a coolant supply through a conduit for supplying coolant toward a grinding surface of the grinding wheel, and a shut-off valve provided on the conduit for allowing the flow of coolant toward the coolant nozzle when in an open state and for blocking the flow of coolant when in a closed state, the apparatus further comprising:
- a wheel unbalance prevention device operable within the period from the switching of the shut-off valve to the closed state to the rotation stop of the grinding wheel and configured to prevent the coolant remaining in the coolant nozzle from dropping on the grinding surface of the grinding wheel so that the grinding wheel is not put out of balance due to the coolant which would otherwise drop on the grinding surface.
