摘要： PROBLEM TO BE SOLVED: To efficiently cut a tubular or rod-shaped product by omitting rise and fall of a grinding wheel head between the uppermost position and a stand-by position. SOLUTION: Position information of a grinding wheel 11 is taken from an encoder into a control device 20, and a grinding wheel head 15 provided with the grinding wheel 11 driven by a grinding wheel motor M is controlled to a set height position by a pitch feed screw 16 driven by an elevation motor 12. In cutting a pipe P, the control device 20 sets a correct stand-by position H0 computed based on an inputted diameter of the pipe P, and preliminarily lowers the grinding wheel head 15 to the stand-by position H0. During a series of work for cutting the pipe P of the constant diameter, the grinding wheel head 15 keeps stand-by at the stand-by position H0 higher than an upper surface position A of the pipe P for a stand-by margin β, so work efficiency is improved. A current value supplied to the grinding wheel motor M may be taken into the control device 20, so the upper surface position A of the pipe P is detected based on the position of the grinding wheel head 15 at the timing when the current value exceeds a specified value for setting the stand-by position H0. In this case, the diameter of the pipe P need not be inputted into the control device 20.
