摘要： 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.

摘要： This disclosure relates to a temperature control system that may be applied to a machine tool. The system includes a cooling circulation and a controller. The cooling circulation comprises a pump, a cooler and a solenoid valve. The pump may be driven by a variable frequency motor so as to flow through the spindle of the machine tool. The cooler is serially connected with the liquid pump, and may cool the liquid coolant. The solenoid valve connects to inlet and outlet of the cooler, and may prevent the liquid coolant flows through the spindle from flowing back to the cooler. The controller is electrically connected with the variable frequency motor, the cooler and the solenoid valve. Further, the controller is connected to the machine tool to detect several parameters, so as to control the variable frequency motor, the cooler and the solenoid valve.

摘要： 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.

摘要： A clamping and positioning device includes a base, a rotary member, a moving assembly and an elastic member. The rotary member is rotatably disposed on the base and includes a stopping surface facing the base. The moving assembly includes a moving member movably disposed on the base to have a first and a second position. When being at the first position, the moving member is pressed against the rotary member to allow the stopping surface to apply a normal force to the base; when being at the second position, a gap is formed between the moving member and the rotary member so the normal force applied by the stopping surface of the rotary member is released from the base. The elastic member has two ends connected to the base and the moving member, respectively. The elastic member normally causes the moving member to be at the first position.
