Subject of research. In the oil industry, parts such as a coupling that have differently directed tapered threads are widely used. The coaxiality of these threads is an indicator of the quality of workmanship and determines the performance of threaded joints. Purpose of work. Improving the manufacturing capacity of the coupling and the accuracy of coaxiality of their differently directed tapered threads. Method. Processing of internal conic smooth and threaded surfaces is carried out in parallel from one and two ends of the coupling, with one installation and position. Implementation. The technology of processing the internal surfaces of the coupling with tapered threads on both sides is proposed, various processing schemes are proposed, a multivariate processing technology is given, the designs of some technological tools and equipment for the implementation of technological processes are proposed. The main results. Some of the proposed options were tested in production, in which all the inner surfaces of the coupling and the ends are processed from one end of the coupling, sequentially, with one installation and position, and gave good results. Practical significance. The machine time for processing conical smooth and threaded surfaces is reduced by more than 1.5 times, the accuracy of coaxiality of multidirectional conical threads is increased by about two times. Conclusion. Application of the proposed technologies, designs of elements of equipment and accessories for their implementation will increase the efficiency and manufacture and operation of parts such as couplings, including their tapered threaded joints.
