Deburring method for intersecting positions of spatial intersection holes

The invention relates to a deburring method, in particular to a high-precision deburring method for intersecting positions of spatial intersection holes, which belongs to the field of mechanical manufacture. The technical scheme includes that the deburring method comprises the steps for removing burrs at the intersecting positions of the spatial intersection holes: 1 machining functional holes ofparts; 2 machining intersection holes of the parts; 3 selecting proper materials for manufacturing a tool; 4 programming machining procedures of a numerical control milling machine; 5 chamfering the intersecting positions of the spatial intersection holes to remove burrs; and 6 removing tiny burrs in subsequent machining process. By the aid of the deburring method, deburring efficiency is higher,operation is simple, controllability is high, the danger that the burrs scratch inner holes during machining is avoided, and the deburring workload of the subsequent machining process is decreased toa large extent.
