What are the components of a CNC optical machine

1 Workbench

The worktable of the gantry machining center is basically rectangular. The large castings such as workbench, bed, column, crossbeam, and slide pillow are made of Mihana cast iron. The inner cavity of the castings is a honeycomb type composite arrangement structure with advanced design, all of which have undergone aging and secondary tempering treatment to eliminate residual internal stress and stabilize the material, ensuring the stability of workpiece processing accuracy and machine life.

The Longmen Gate consists of a crossbeam and two columns. It is divided into three types: beam fixing, beam locking with positioning blocks for segmented lifting, and beam arbitrary lifting.

Three types of sliding pillows can be structurally divided into open and closed types. The open structure slider is clamped onto the spindle box through a pressure plate, and the cross-sectional area of the slider is large; The closed structure slider is clamped inside the spindle box, and the cross-sectional area of the slider is small.

There are three basic types of knife magazines: turret type, drum type, and chain length type.

The processing of large and complex parts in the attachment head library usually requires a lot of attachment heads. Attachment heads are specially designed according to the processing requirements of the workpiece, generally divided into right angle heads, extended heads, special angle heads, and universal heads.

The CNC system generally adopts SINUMERIK840C and 840D from SIEMENS in Germany or 15 and 16 series from FANUC in Japan, and the CNC axis adopts full closed-loop control.

The precision of a 7-precision machine tool refers to its original accuracy under conditions where it is not subjected to external loads. Accuracy is usually represented by its opposite - the deviation from the ideal state (referred to as error), and the smaller the error, the higher the accuracy.
