MODIFICATION OF THE BACKING-OFF LATHE TO THE NC SCREW-GRINDING MACHINE
Long Wang · Journal of Yangzhou University · 2001
Techniques of modifying a backing\|off machine to a NC screw\|grinding machine are presented. After analyzing the particularities and the motion characteristics of the latter, the system includes a 3 coordinate AC servomotor, a grinding wheel whose angle is fixed during the process and a emery wheel as the grinding\|wheel dressing tool. The NC screw\|grinding machine after modified can not only calculate the sectional shape of the grinding\|wheel simultaneously while grinding, but also program for the grinding\|wheel dressing and the whole grinding process automatically.
