Abstract

PURPOSE:To prevent heat transfer of a work in autocutting operation and hold its chucked part to prescribed temperature, by using a heating unit in a chuck pawl part, thermally insulating member between the heating unit and machine main unit and a temperature control device, controlling a heating amount of the heating unit. CONSTITUTION:A heating unit 5 of ceramic heater is arranged between a chuck pawl part 1 and thermally insulating members 6, 7 of mica or asbestos cement. Heat transfer to an oil hydraulic chuck main unit 4 is prevented by a thermally insulating member 8 of synthetic resin. The pawl part 1 is kept at prescribed temperature by a temperature control device 9. The temperature control device 9 is connected to the detecting end of a thermocouple 10, embedded to the inside of the pawl part 1, to compare its detected temperature, on-off control the heating unit 5 and hold the pawl part 1 to prescribed temperature.
