The original construction of assembling and machining centers is offered that with the purpose of expansion technological abilities, increase of a universality, productivity and more complet usage of working space - assembly, instrumental and loading positions are disposed on surfaces of three spheres with an opportunity of their directional coincidence according to the requirements of realizable manufacturing processes. This the special attachments and mechanisms for coincidence positions of spheres which one raise the rigidity and accuracy of manufacturing processes is stipulated. The constructions assembling and machining of spherical centers were licensed.
The construction of self-placing backlash-free experimental bearing with barrel-type modular rollers is described. The procedure of its evaluation for contact strength, static and dynamic weight-lifting capacity is shown.
