In its continuous rolling equipment, there are some inclined positioning surfaces in the windows of the parts of the foot roll stand. These inclined positioning surfaces are used to position the rolls and bearing seats, so their positioning accuracy requirements are relatively high. Due to the relatively narrow positioning space, it is impossible to use the angle milling head on the boring machine or milling machine for processing. It is usually processed on the slotting machine. However, since these processing surfaces are inclined, it is difficult to clamp the workpiece, align the tool, and measure. It is difficult to meet the use requirements. It is highly dependent on the skills of the machine tool operator, with low efficiency and low yield. Summary of the invention
