Abstract
Description
technical field
[0001] The invention belongs to the field of processing equipment, and relates to a double-cutter blind hole fixed-depth machining numerical control machine tool. Background technique
[0002] Due to the deepening of oil production depth, the consumption of oil production perforating guns is increasing. At the same time, the deeper the depth of the underground or the pressure on the seabed, the more stringent the wall thickness requirements for perforating guns, resulting in blind holes. Depth requirements are also getting stricter. However, since the length of the pipe is more than 10 meters before processing, its straightness cannot be guaranteed, and the processing depth limited by the numerical control system for the curved pipe cannot fully guarantee the processing accuracy. The convex surface is often processed too deep, and the concave surface is often processed insufficiently. , such processing can only meet the processing accuracy with large dimensi...
