The results of a long-term scientific work in the field of the creation of machines, plants, devices for machinery finishing for the creation of innovation equipment based on screw rotors are shown. There are presented standard structures of machines ensuring machining a wide range of parts of engineering enterprises. There are formulated basic recommendations for a choice of machining operation environment as such one can use abrasives and non-abrasives of different granulation. These recommendations take into account material, mass, rigidity of the parts worked and a grade of screw rotors. There is shown an example of calculation and an experience of designing a plant for parts continuous grinding-finishing on the basis of a screw rotor of the IIId grade. Working drawings and technologies for manufacturing operation units of these machines and plants are offered.
