Abstract: A temperature regulation system and a temperature regulation method are applicable to a machine tool. The temperature regulation system includes a cooling fluid storage tank, a heating fluid storage tank, an internal circulation subsystem, an external circulation subsystem and a computing unit. The internal circulation subsystem includes a first valve. The external circulation subsystem includes a plurality of flow channels and a second valve and a third valve disposed on the plurality of the flow channels. The computing unit controls the first valve, the second valve and the third valve to switch flow directions of the plurality of the flow channels among the cooling fluid storage tank, the heating fluid storage tank and machine tool. Therefore, a thermal balance of the machine tool can be effectively maintained.

Abstract: The disclosure is a thermal stability control system and a control method thereof for a machine tool. The control system mainly consists of a machine cooling sub-system composed of a pump, at least a cooling loop and a tank for storing cooling fluid, a cooling fluid cooling and heating sub-system, a heater and a micro controller. The cooling fluid cooling and heating sub-system further consists of a condenser, an evaporator, a directional valve, an expansion valve and a compressor. The micro controller dominates corresponding operation combinations of turning on/off the heater, enabling/disenabling the cooling fluid cooling and heating sub-system as a heat pump or a cooler by activating/releasing the directional vale, and adjusting upward/downward the driving frequency of an inverter duty motor to drive the pump to change the flow rate of cooling fluid through the cooling loop according the real time load of the machine tool.

Abstract: A device of the axial-directional oil chamber of hydrostatic spindle comprises integrated oil seal structures at both the axial direction and the radial direction. The oil seal structures increase the work area of the oil chamber by extending and thus connecting an axial-directional oil seal edge to a radial-directional oil seal edge. Then, the rigidity of the axial hydrostatic bearing can be increased, and thus the application capability of the hydrostatic spindle can be upgraded to perform the multi-task machining from the mono-task machining.
