Claim Text:
1. A cutting fluid control device for a machine tool, which comprises: a cutting fluid undiluted-solution supply device configured to supply an undiluted solution of a cutting fluid to a cutting fluid tank; a water supply device configured to supply water for diluting the cutting fluid undiluted-solution in the cutting fluid tank; and a concentration sensor configured to detect the concentration of the cutting fluid in the cutting fluid tank, wherein the cutting fluid control device adjusts the amounts of supply of the cutting fluid and the water to control the concentration of the cutting fluid in the cutting fluid tank, the cutting fluid control device further comprising: an operating unit configured to input a machining condition of the machine tool; a computing unit configured to calculate the concentration of the cutting fluid based on the machining condition input through the operating unit; and an adjustment unit configured to adjust the amounts of supply from the cutting fluid undiluted-solution supply device and the water supply device so that the concentration of the cutting fluid in the cutting fluid tank is equal to the cutting fluid concentration calculated by the computing unit.
