Abstract
PURPOSE: To correctly bring a grindstone into contact with a flaw of a workpiece, by enabling lifting the grindstone by a constant distance from the movement locus of the workpiece.
CONSTITUTION: When a grindstone 4 is elevated out of contact with a workpiece 23, the decrease in the current of a motor 6 is detected by a discrimination circuit 15 and a separation detection signal is supplied to a control calculation circuit 18. At that time, an elevated position signal of the grindstone 4 entered into the circuit 18 from the body 12 to of a detector 11 through an input circuit is temporarily stored in the circuit 18. An arm 2 is tilted further to elevate the grindstone 4. When the difference between the temporarily stored signal and another elevated position signal applied from the body 12 the control calculation circuit 18 through the input circuit 19 has become a quantity corresponding to a value set in a distance setting unit 20, the elevation of the grindstone is stopped ant the grindstone is retained at a prescribed height H from movement locus 22.
