PROBLEM TO BE SOLVED: To provide a spindle lubricating device considering a temperature change around the machine in a machine tool. SOLUTION: The spindle lubricating device of the machine tool is equipped with: a temperature sensor 1 for detecting the temperature around the machine; a speed sensor 5 for detecting the rotational speed of the spindle; a supply means 3 for supplying the lubricant to the bearing for the spindle in a manner that the supply amount is variable; and a calculation means 2a for calculating the supply amount by the supply means 3 based on the output signals of the temperature sensor 1 and the speed sensor 5.
