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.

A cutting fluid supplying device for a machine tool includes a machine tool having a structure body including a bed, a column disposed on the bed, and a spindle head disposed to the column and at least one of the ejection ports for ejecting a cutting fluid. The cutting fluid supplying device for a machine tool further includes a storage tank for storing the cutting fluid to be supplied to the machine tool, at least one of the cutting fluid flow passages for connecting the storage tank and the at least one of the ejection ports, and at least one of the pumps for applying pressure to the cutting fluid to supply the cutting fluid stored in the storage tank to the at least one of the cutting fluid flow passages. The at least one of the cutting fluid flow passages is disposed to penetrate through or disposed on an outer surface of the structure body so as to allow heat exchange between the cutting fluid and the structure body.

A coolant distributor comprising a head having a plurality of ports, each of the ports being fluidly coupled to a flow control valve. A cap is demountably coupled to the head. The cap comprises at least one fixed nozzle fluidly coupled to at least one port. A controller is coupled to the flow control valve, wherein the controller is configured to actuate the flow control valve to pass a cooling fluid through the at least one fixed nozzle to direct the cooling fluid to at least one predetermined cutting region of a machine tool and work piece proximate the coolant distributor.

A machine tool includes a thermoacoustic apparatus and a fluid supply apparatus, utilizes exhaust heat from a constituent apparatus of the machine tool to cool a heat exchanger included in the thermoacoustic apparatus due to a thermoacoustic effect. Thus, a cooling fluid is cooled which is used to cool a bearing and a machining point.

In a processing machine, a machine body drives at least one of a workpiece and a tool to process the workpiece by the tool. A processing chamber isolates the workpiece, the tool, and a nozzle from at least part of the machine body while housing the workpiece, the tool, and the nozzle. An internal temperature sensor measures a temperature of an atmosphere in the processing chamber. An external temperature sensor measures a temperature of an atmosphere around the processing machine. A temperature adjustment part raises a temperature of the processing fluid to be supplied to the nozzle when a measured temperature of the internal temperature sensor is lower than a measured temperature of the external temperature sensor, and/or the temperature adjustment part lowers the temperature of the processing fluid to be supplied to the nozzle when the measured temperature of the internal temperature sensor is higher than the measured temperature of the external temperature sensor.
