Improving of Machining Efficiency of Threads and Conical Surfaces of Diverse Directions by Managing Static Technological Relationships

Abstract

In the work, the design of the tool – boring bar for parallel machining of conical surfaces and threads in coupling-type parts with opposite directions, same inclination, coaxial conical surfaces and threads is given, and their generalized design features are presented for the machining of couplings of different types and sizes. With the application of the designed tool - boring bar to machining of inner surfaces of couplings, their machining accuracy, especially accuracy of coaxiality of threads, thus the load-carrying capacity of the couplings increases, the technological cost of their production is reduced, and the efficiency of their use is ensured.
