Abstract:
[Problem] To provide a substantially cylindrical separable tool holder unit that at detects, in real time, at least the temperature and/or vibration of a rotary tool with which a rotary processing device is performing processing. [Solution] This separable tool holder unit comprises a chuck part that grips a rotary tool at the bottom of the chuck part is vertically coupled with a shank part that is joined to the top of the chuck section at the bottom of the shank part and is gripped by the main shaft of a rotary processing device at the top of the shank part. The chuck part comprises: an annular brim part that protrudes around the outer periphery of the chuck part at a vertically central position thereof; and a chuck-side coupling part that forms a taper part reducing in diameter upwards from the brim part and that has a cylindrical recessed space on the inside thereof. The shank part has a shank-side coupling part that has therein a taper recess part increasing in diameter downwards. The taper part of the chuck-side coupling part can be inserted into the taper recess part and engaged therewith in a nested manner. An insulated electronic board unit is inserted, from the chuck part, into the recessed space of the chuck part and receives the temperature and/or vibrations from the rotary tool.
