MACHINE TOOL DRIVING APPARATUS

摘要

PURPOSE: A machine tool driving device having the temperature controller of a hydraulic oil is provided to reduce an initial operation time in winter time and to reduce machining error by preventing the overheat due to drive heat in summer time. CONSTITUTION: A machine tool driving device comprises a temperature controller(10) of hydraulic oil. The temperature controller of the hydraulic oil comprises a cooling line(30), first and second on/off valve s(40,60), a heating line(50), a temperature sensor(70) and a controller(80). The first switching valve is installed in the cooling line. The second on/off valve is installed in the heating line. The heating line interlinks the inlet of the compressor and the outlet of the evaporator.
