Description

[0002] The horizontal boring machine is the most widely used boring machine. It is mainly used for hole processing, and the boring accuracy can reach IT7. In addition to expanding the holes cast or processed on the workpiece, the horizontal boring machine can also mill planes, drill, process end faces and the outer circle of flanges, and cut threads, and is mainly used in single-piece small-batch production and repair workshops. The roundness error of the processed hole is not more than 5 microns, and the surface roughness is Ra0.63-1.25 microns. The main parameter of the horizontal boring machine is the diameter of the main shaft.

[0003] The existing horizontal boring machine cannot correct the roundness runout or total runout of the workpiece during the processing of the cylindrical workpiece. Only after the processing is completed, the roundness runout or total runout tolerance value can be measured. However, the tolerance of the roundness runout or total runout of the cylindrical workpiece has strict tolerance requirements. If the tolerance does not meet the requirements after the processing is completed, the batch of defective products may be produced, which needs to be repaired or even scrapped, thereby increasing the labor cost and wasting time, and there is room for improvement.
