How is the layout of horizontal machining center?

The various types of horizontal machining centers vary with the horizontal and vertical, table feed movements and axle box feed movements, but overall, the basic parts, spindle parts, The numerical control system, the automatic tool change system, the automatic pallet change system and the auxiliary system are composed of several parts. The CNC milling machine has no tool change system, and its layout features are similar to the machining center.

Horizontal machining center usually adopts mobile column, the table does not lift, T-shaped bed. The T-shaped bed can be made into one body, so that the rigidity and accuracy are better maintained, and of course the casting and processing technology is poor. The casting and machining technology of the separate T-shaped bed are greatly improved, but the connecting part should be positioned with positioning keys and special positioning pins, and large size bolts are used to ensure rigidity and accuracy.

The vertical machining center column generally adopts the structure of the double column frame structure, the spindle box moves between the two columns, and moves up and down along the guide rail. This structure has high rigidity, good thermal symmetry and high stability. Most of the small horizontal machining centers use a fixed column structure, the bed is not large, and they are all integral structures.

The movement of each coordinate of the horizontal machining center can be completed by the table movement or the spindle movement, that is to say, the movement in a certain direction can be completed by the tool fixed and the workpiece moved, or by the workpiece fixed and the tool moved.
