Abstract

PURPOSE:To work right slots even if the speed of revolution of a main shaft changes in the first thread cutting working and thread cutting working after that of one screw. CONSTITUTION:A pulse generator 4 is connected to a main shaft 2 that can freely be revolved, and a plurality of synchronous pulses NP per one revolution of the main shaft and one specified revolution location pulse 1P at a specified revolution location during one revolution of the main shaft are generated to a NC device 5. The NC device 5 synchronizes with said NP in succession to feed starting action, of which a FF18 switches reset signals PST OFF, on the basis of numerical value information by means of an instruction tape PT and distributes pulses, and delivers distributed pulses XP to an X-axis servo-motor 6 in a shape that responds to said 1P. In this case, the NC device 5 is formed in such a manner that it builds in a false, specified, revolution location pulse NIP generating circuit 20, N1P is generated before a fixed time from a point of time when said 1P is produced and thread cutting action is started in response to the output.
