A water temperature setting method for a processing apparatus for processing a workpiece held by a holding table by rotating at a high speed a spindle with a processing tool mounted thereto and supplying processing water to the processing tool. A set temperature for the processing water supplied to the processing tool is set to be higher than a set temperature for spindle cooling water supplied to a spindle unit that rotates the spindle at the high speed, in consideration of a lowering in temperature due to evaporation of the processing water scattered from the processing tool due to the high-speed rotation of the processing tool.

A fluid temperature control assembly in combination with a machine tool, and a method of adjusting the temperature of a fluid being supplied to a machine tool. The assembly is arranged to adjust the temperature of a fluid being supplied to the machine tool to maintain the fluid at a setpoint temperature at a location downstream of the assembly. The assembly comprises a radio frequency (RF) or microwave energy source to supply energy to the fluid as it passes through the assembly to heat the fluid, a temperature sensing arrangement for outputting a temperature signal responsive to the temperature of the fluid at the downstream location, and a control arrangement configured to receive the temperature signal and control the energy source with reference to the temperature signal to heat the fluid so as to maintain the fluid at the setpoint temperature at the downstream location.
