Abstract
An object is to provide a nozzle controller which can constantly cool a tool in a machine tool. A nozzle controller of a machine tool includes: a tool which is gripped in a spindle of the machine tool; a nozzle in which the angle and/or the position thereof with respect to the tool can be changed and which emits a fluid to the tool; a nozzle drive unit which drives the angle and/or the position of the nozzle; a contact acquisition unit which acquires contact between the tool and a work; and a control unit which controls the nozzle drive unit. The control unit calculates, when the contact acquisition unit acquires the contact, based on a length of the tool and a stroke of a feed axis in the direction of the spindle, the angle and/or the position of the nozzle such that the fluid emitted from the nozzle hits a side surface of the tool, and controls the nozzle drive unit based on the result of the calculation.
