Abstract
PURPOSE: In a steel tube cutter for cutting steel tubes with a plurality of cutting tools, to ensure ideal cutting by automatically balancing the cutting depths of said cutting tools without manual adjustment.
CONSTITUTION: Tool-rest driving DC serbo-motors 1a and 1b, independent from each other are used as a standard motor driven at a constant speed dependent on the feed speed of cutting tools that is determined in accordance with cutting condition and as a follower motor driven while maintaining the balance thereof with said motor 1a respectively. The load current of said serbo-motors 1a and 1b are detected by current detectors 10a and 10b, and said follower motor 1b is controlled by using the compensation value obtained dependent on the difference of load current value between said both serbo-motors 1a and 1b. Further, when detected by a motor load detecting circuit 13, the continuance of no-load by a motor-load detecting circuit 13 for a fixed period of time is judged to indicate the breakage of said cutting tools and said cutting tools are reversed.
