Abstract: A cutting machining apparatus 1 includes: a head 5 including a spindle drive 51 that rotary drives a rotary spindle with a tool 20 secured to a tip of the rotary spindle; a proximity sensor 34; a signal acquirer obtaining a signal waveform of a detection signal that is output from the proximity sensor 34 when the rotary spindle 52 is rotated in a state in which the head 5 is moved so that the proximity sensor 34 faces a lateral side of the tool before and after cutting machining of the workpiece W using the tool; and a determiner determining whether or not the tool 20 is broken based on whether or not there is a difference in signal waveforms obtained before and after the cutting machining.

Abstract: A workpiece holder 1 includes a holder head 11 and a holder body 12. The holder head 11 includes a chuck unit 13 for holding a workpiece W, a support pedestal 111 for supporting the chuck unit 13, and a hook 113 provided on a distal end portion of an arm 112 extending from the support pedestal 111. The holder body 12 includes a cylindrical body portion 121, a retained portion 123 that is arranged inside the body portion 121 and rotated around the cylinder axis J1 to be in either a retained state in which the retained portion 123 is retained by the hook 113 on the −Z direction side or in the released state in which retaining by the hook 113 is released, and a disk spring 126 for biasing the retained portion 123 in the −Z direction.
