PURPOSE: To realize removal of cuttings automatically and in a short time by the captioned device which removes cuttings accumulated on a table of a machine tool by equipping a main shaft of the machine tool with an electromagnet and adsorbing thereby the cuttings on a table and further discharging them.
CONSTITUTION: An adsorptive part 11 formed by winding a coil 12 around a magnetic material and a fitting part 13 of nonmagnetic material are united in one body by means of a holder 10 for removing cuttings. A coil 12 equipped with a terminal 14 is connected to an outside power supply. When a program of cuttings removal is started, the holder 10 is fitted in a main shaft 2, and the power supply is automatically connected to set the coil 12 conductive, then the adsorptive part 11 is magnetized to adsorb cuttings on a table 5. After completion of this adsorption, the holder 10 is carried to a discharge part, and conductivity to the coil 12 is turned off, then the adsorptive part 11 is demagnetized, and cuttings drop into a discharge part.
