Metal inclined hole drilling method of composite materials

Metal inclined hole drilling method of composite materials

A metal inclined hole drilling method of composite materials comprises the following eight steps: 1, positioning and tightly clamping; 2, performing helical milling to obtain an inclined hole with the diameter being 12.3; 3, drilling to obtain a through hole with the diameter being 9.3; 4, drilling...

description A metal inclined hole drilling method of composite materials comprises the following eight steps: 1, positioning and tightly clamping; 2, performing helical milling to obtain an inclined hole with the diameter being 12.3; 3, drilling to obtain a through hole with the diameter being 9.3; 4, drilling to obtain an M16 thread bottom hole; 5, boring to obtain a counterbore hole with the diameter being 17.4; 6, tapping by using a machine tool to obtain an M16*2 thread; 7, manually tapping to obtain an M16*2 thread; 8, disassembling the tooling after completion of machining. Aiming at the common typical characteristic of aerospace products, namely the connecting inclined hole, the method solves the problems that cutter relieving is easy to occur in the metal inclined hole machining of composite materials, the machining precision is low and the drilling jig dependence is high, provides an effective solution for the inclined hole drilling of a special shaped housing on which the drilling jig cannot be mounted, and fur
