摘要： 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.

摘要： A core support system includes a support structure. The support structure includes a frame and a support member having a saturatable engagement layer disposed over the frame. A method of machining a core material incudes applying a fluid to an engagement layer of a support structure and saturating the engagement layer with the fluid, disposing a core material on the engagement layer, causing the fluid to freeze to secure to the core material to the support structure, machining the core material, melting the frozen fluid to release the core material from the support structure, and removing the core material from the engagement layer.

摘要： A machining accuracy diagnosing device includes a diagnosing information acquiring, an opening time setting unit, a cutting time setting unit, and a machining accuracy influence amount predicting unit. The diagnosing information acquiring unit acquires at least one of a room temperature inside the plant, a set temperature of a temperature regulating device, an air temperature outside the plant, a wind speed outside the plant, an opening degree of the door or the shutter, and a machine body temperature. The opening time setting unit sets an opening time of the door or the shutter. The machining accuracy influence amount predicting unit predicts an influence amount of opening of the door or the shutter on the machining accuracy based on the acquired information for diagnosis, the set opening time of the door or the shutter, and a set scheduled machining start time and a set scheduled machining end time.

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： The invention provides a method for modeling and compensating for the spindle's radial thermal drift error in a horizontal CNC lathe, which belongs to the field of error compensation technology of CNC machine tools. Firstly, the thermal drift error of two points in the radial direction of the spindle and the corresponding temperature of the key points are tested; then the thermal inclination angle of the spindle is obtained based on the thermal tilt deformation mechanism of the spindle, and the correlation between the thermal inclination angle and the temperature difference between the left and right sides of the spindle box is analyzed. According to the positive or negative thermal drift error of the two points that have been measured and the elongation or shortening of the spindle box on the left and right sides, the thermal deformation of the spindle is then classified and the thermal drift error model under various thermal deformation attitudes is then established. Then the influence of the size of the machine tool's structure on the prediction results of the model is analyzed. In real-time compensation, the thermal deformation attitude of the spindle is automatically judged according to the temperature of the key points, and the corresponding thermal drift error model is automatically selected to apply the compensation to the spindle. The method is used to distinguish the thermal deformation attitude of the spindle in a CNC lathe, and the thermal deformation mechanism is used to predict the radial thermal drift error of the spindle.

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 regeneration device for regenerating a coolant dispersion with phase change material includes: a redispersion unit for redispersing the coolant dispersion, the redispersion unit including a restrictor; and a recooling unit that enables freezing of a phase change material by dissipating heat stored in the coolant dispersion. The recooling unit is arranged so that dissipated heat is at least partially recuperated in order to heat up the coolant dispersion to an inlet temperature.
