    摘要: An apparatus in a machine tool controls the flow of coolant in accordance to tool contact with a workpiece. The preferred embodiment measures and stores a torque value exerted upon a spindle motor under no-load conditions and compares this value to an operating torque value upon the same spindle motor. When the tool contacts a workpiece and the operating torque exceeds the stored no-load torque value by a predetermined amount, a solenoid operated valve is opened and coolant is permitted to the area of tool engagement with the workpiece.
