The following theme, Lathe work, Welding operation, milling machine work, NC machine work. etc.,are practiced in training factory of Fukushima National College of Technology. Lathe work has moreopportunity of the accident than other machine tools. For example, the accidents which student is ro tating chuck with chuck handle happen 10 times in a year. In this paper. therefore. the simple safetydevice was developed, and this equipment was installed in 11 lathes in training factory. As a result,1) The safety device was able to be prevented the accident of chuck handle dispersion. Because of thelathe did not start. when the chuck handle was not put in the equipment.2) Operating condition and work situation of the all lathe machines were able to be grasped accuratelyby the 3 colors speciﬁcation light. It would be possible to carry out the appropriate guidance.3) Safety device is maintained easily by the control equipment is simpliﬁed. There is no malfunctionand trouble since the safety device was installed. It is found that the safety device is very effectivefor prevention of accident.
