The trampoline processing is mainly composed of the bed body, the column, the headstock, the tailstock and the workbench. Its movement mode is the main motion of the main shaft and the axial movement of the main shaft. The table can realize the vertical and horizontal movement and can make the rotation angle. The main shaft and the mast support can be moved up and down, and the tailstock can be moved horizontally by the guide rail, which mainly performs the cutting process on the boring machine.
This type of processing is mainly used on some large or more complex holes, and its surface roughness accuracy can reach 1.6-0.8μm. It can also correct the original deviation axis and position.
