Large milling machine with swivelling parts

According to the processing characteristics of large rotating parts, this series of machine tools uses the world-wide popular column displacement scheme, the three-way movement is concentrated in the tool, which can ensure that when changing the machined parts, the three-way drive load remains unchanged, with stable dynamic characteristics. Its structure in the form of a cross on the statin body movement is X direction, the machine spindle box in the column for up and down movement is the machine Y direction. Column in transverse support. The movement of the column on the transverse cutters is represented by the Z direction of the machine, and the machined parts are supported by two hydrostatic central frames and rotate at both ends as an axis A. To improve the work efficiency, the milling part can be arranged symmetrically with respect to the machined parts, Both sides can be processed at the same time.

Processing range and productivity

This series of machine tools is especially suitable for milling turbine rotor or other parts with rotating characteristics, with a large machining range, strong load capacity, high rigidity and machining accuracy of the machine tool as a whole, and good precision preservation, which enhances the performance and manufacturing accuracy for machining rotor grooves, especially inclined grooves and grooves with a circular arc. This series of machine tools can meet the black processing of medium 600 disc milling machine to achieve high torque of 7000 Nm, and at the same time, achieve stable and high-precision clean processing of small diameter milling machine with CNC interpolation.

High-precision, high-stability, high-load indexing rotating device

The special structure of the support plates of the front and rear supports of the rotating device allows the rotor to generate minimal frictional force when rotating, avoiding deformation of the front and rear ends of the rotor due to the frictional moment of the supporting parts. The transmission uses precision worm gears with twin leading screw and worm gears, and high-precision angle encoders are installed for comparison at any time to ensure the accuracy of the rotor indexing.

Excellent feed drive system

River drive is adopted for large stroke, avoiding many drawbacks of long screw drive. River transmission, the use of international advanced double engine, double teeth lift technology. Troubleshoot at any time to ensure transmission performance.

In order to adapt to different working requirements, this machine tool series adopts three different guide configuration: precision large-scale guide swing to meet the needs of high-speed, high-reactivity machining; inlaid steel casting guide slide to meet the requirements of powerful heavy cutting; large size swing guide damping unit inlaid steel casting guide slide to meet the requirements of high-speed, heavy cutting.

High rigidity spindle transmission system

The main drive of this series machine tools uses gear mode, the spindle transmission structure has the advantages of good rigidity, high accuracy, fast reaction speed, low vibration. Positioning accuracy and other advantages. This machine is equipped with an oil radiator for circulating cooling of the spindle gears and reducer bearings, so that the heat of the main drive during operation is discharged with circulating oil from the machine body. A constant temperature is maintained in the main drive system, which guarantees stable operation accuracy.
