Abstract
A temperature control device includes a machine body temperature sensor which measures a machine body temperature at a portion separated from a spindle device, a return oil temperature sensor which measures a temperature of cooling oil which circulates in a machine tool and which is collected by the temperature control device, an oil controller which includes at least two oil control modules, each having a cooler and which control the temperature of the cooling oil so that the temperature of the cooling oil detected by the return temperature sensor is synchronized with a reference temperature set based on a machine body temperature, in which tanks thereof communicate with each other, and the at least two oil control modules are connected in parallel to the machine tool, and a piping connection manifold for uniformizing convergence of the cooling oil to the machine tool and branching to each of the oil control modules.
