Introduction to the Structure of Large CNC Vertical Turning Machine in Longmen Machining Center

The workbench of the gantry machining center is basically rectangular. The large castings such as workbench, bed, column, crossbeam, and slide pillow are made of mihanna cast iron. The inner cavity of the castings is a honeycomb composite arrangement structure with excellent design, and all have undergone aging and secondary tempering treatment to eliminate residual internal stress and ensure the stability of the raw materials, ensuring the machining accuracy of the workpiece and the service life of the machine< Br/>


2. Longmen



The gantry is composed of a crossbeam and two pillars. It is divided into three types: fixed crossbeam, segmented lifting of crossbeam locked by positioning blocks, and arbitrary lifting of crossbeam< Br/>


3. Sliding pillow



Sliding pillows can be divided into two types structurally: open and closed. The sliding pillow with an open structure is clamped onto the spindle box by a pressure plate, and the cross-sectional area of the sliding pillow is large; The closed structure of the slider is clamped in the spindle box, and the cross-sectional area of the slider is small< Br/>


4. Tool magazine



There are three basic types of tool libraries: turret type, drum type, and chain length type< Br/>

5. Attachment header library



The processing of large and complex parts generally requires many accessory heads. The attachment head is specially designed according to the processing requirements of the workpiece, generally divided into right angle head, extended head, and special viewpoint head< Br/>


6. CNC system



The CNC system is generally selected from German or Japanese companies, and the CNC axis adopts full closed-loop control< Br/>


7. Accuracy



The accuracy of a machine tool refers to its original accuracy without being subjected to external loads. The accuracy is generally measured by its dissonance; The deviation from the ideal situation (referred to as error) is used to indicate that the smaller the error, the higher the accuracy< Br/>
