MACHINE TOOL AND HEAT DISPLACEMENT SUPPRESSING METHOD FOR MACHINE TOOL

摘要

PROBLEM TO BE SOLVED: To suppress heat displacement by a simple constitution in a machine tool and a heat displacement suppressing method for the machine tool. SOLUTION: A cutting oil supply pipe 22 for supplying cutting oil from a storage tank 21 to a cutting part 20 and a cutting oil discharge pipe 23 for discharging the cutting oil to the storage tank 21 are provided. A temperature sensor 36 for detecting a discharge temperature Toutof the cutting oil is mounted on the cutting oil discharge pipe 23. A temperature sensor 37 for detecting the lower surface temperature TBis mounted on a bed 11. A control device 38 drives and controls a cooler unit 27 so that the discharge temperature Toutof the cutting oil may be the lower surface temperature TBof the bed 11 and adjusts and controls a supply temperature Tinof the cutting oil to be supplied to the cutting part 20.
