Abstract: After analyzing the processing method of the flow control sleeve’s inclined holes, if taking the primary positioning method to pro-cess each two opposite holes on total four surfaces, it is proved that it can’t be achieved by the current facilities that exist in our company, such as vertical machining center, horizontal it’s hard to make the complete drilling mould. The special drilling mould with separate struc-ture and also can be used in combination way is designed. Respectively take the special drilling mould’s six surfaces and the two surfaces of the V-type block to position in the drilling machine, not only successfully resolve the sleeve’s inclined.
