    摘要: A milling machine has a carriage, a main spindle seat extending along an axis, and a motor operable to drive displacement of the main spindle seat relative to the carriage along the axis. A deflection correction system includes a control unit, a displacement sensor, at least one pressure cylinder, and a pressure sensor. The pressure cylinder includes a cylinder body, and a control rod extended retractably into the cylinder body. The control unit is configured to determine a pressure range as a function of displacement detected by the displacement sensor, and to maintain fluid pressure in the pressure cylinder within a pressure range, thereby controlling the control rod via the cylinder body to position the second end portion of the main spindle seat relative to the axis.

    摘要: A spindle control system for a milling machine is provided. The milling machine includes a column, an overarm, a spindle for mounting a cutter, a first motor mounted on the column for driving movement of the overarm, and a second motor mounted on the overarm for driving rotation of the spindle. The spindle control system includes a distance sensor and a temperature sensor, each to be mounted on the overarm and to be disposed proximate to the end portion of the spindle. The spindle control system further includes a central control unit for determining a compensation parameter based on the displacement sensed by the distance sensor and the temperature sensed by the temperature sensor, and for controlling movement of the overarm by the first motor through a compensation distance based on the compensation parameter to compensate for at least one of the cutter deformation and the spindle deformation.

    摘要: A milling machine has a base, a work platform mounted movably on the base, and a ruler mounted on the work platform. The work platform is movable relative to a base axis. The thermal compensation system includes a sensor and a control unit. The sensor is configured to be mounted on the base for sensing a position of each of the work platform and the ruler relative to the base axis. The control unit is coupled to the sensor, and determines a work platform displacement and a ruler displacement according to the positions sensed by the sensor. The control unit further calculates a compensation value based on the work platform displacement and the ruler displacement. The control unit is configured to correct the position of the work platform relative to the base axis according to the compensation value.
