Abstract
An automatic cutting liquid supply apparatus which automatically supplies a cutting liquid to each tool of a machine tool in accordance with predetermined optimal cutting liquid supply conditions that include variations over time during operation. The optimal supply conditions of the cutting liquid supply quantity (Q) are preset for each type of tool (1) in a control device (5). The control device (5) is constructed from a main control section (5a), which mainly controls the driving of the main shaft units (2) on which the tools (1) are mounted, and an automatic supply control section (5b), which automatically controls the cutting liquid supply quantities (Q). An input signal (Vin) corresponding to the supply conditions (preset) is inputted into the variable frequency generating device (5c) from the automatic supply control section (5b). The variable frequency generating device (5c) generates an output frequency signal (F) that corresponds to the input signal (Vin) and transmits this output frequency signal (F) to the cutting liquid supply device (3). The cutting liquid supply device (3) supplies cutting liquid supply quantities (Q) that are proportional to the output frequency sig…
