The invented improvement is that an overtravel-limit switch is newly added in the circuit which can uplift the tool head sliding plate of the existent Y4232C type gear-shaving machine. During finishing, through regulation of the stop block travel of the overtravel-limit switch, it can make the normally opened contact of the 12XK overtravel-limit switch to close up 0.5-1.5 sec. ahead of 13J or 15J relay, and thus the goal that the tool head can lift the tool 0.5-1.5 sec. ahead of stop is attained. |
