<p>An apparatus for supplying cutting liquid automatically according to optimal cutting liquid supply conditions, including variation with time during operation, predetermined for every tool of a machine tool. Optimal supply conditions of the cutting liquid supply (Q) are preset in a control means (5) for respective types of tools (1). The control means (5) comprises a main control section (5a) for mainly controlling the driving of a spindle unit (2) equipped with the tool (1), and an automatic supply control section (5b) for controlling the cutting liquid supply (Q) automatically, wherein the automatic supply control section (5b) delivers an input signal (Vin) corresponding to a supply condition (preset) to a variable frequency generating means (5c). The variable frequency generating means (5c) generates an output frequency signal (F) corresponding to the input signal (Vin) and delivers it to a cutting liquid supply means (3). The cutting liquid supply means (3) supplies a cutting liquid in amount (Q) proportional to the output frequency signal (F) to the tool (1) from a cutting liquid tank (3a) using a supply pump (3c).</p> |
