As a part of researches on temperature control of machine tools, the means to measure the circuit constants in temperature-control circuits, which must be established in order to design such a circuit , when the spindle head is cooled by jacket cooling, has been. studied. The following results were obtained : (1) The most appropriate position to mount the detector for temperature control, is the ournal part of the spindle head, which is closest the cooling unit. (2) In the case that the construction of spindle head enables the measurement of cooling capacity, the cooling capacity needed can be estimated by first varying the cooling capacity at steady state, and then observing the changes in temperature, to derive the relationship between the temperature elevation and the cooling capacity. (3) The transfer function for the temperature elevation of spindle head may be assumed to be a series of a dead time element and a first order lag element. (4) The above function is adequately obtained by observing the step response and the frequency response within a short period of time, say a few minutes
