The paper deals with the issues of the improvement of technological procedures aimed at machining of geometrically complex part surfaces, including the complex automation of technological procedures, and the intensification of machining processes due to wide application of high speed and creep feed grinding methods. The paper highlights today's solutions in the area of design and production of high-tech grinding equipment to grind geometrically complex surfaces of engineering parts, in particular, those of outer surface profile of turbine blades. The presented equipment layouts and the figures of working areas enable one to implement the automated technological procedures of machining using high-performance grinding methods as cutting processes. These engineering solutions allow one to machine the most quantity of geometrically complex part surfaces in one set in one coordinate system, to implement the technologies of high-speed creep feed grinding both with single-layer wheels with nickel-galvanic bond and the grain of hard-to-cut materials without wheel dressing and with the wheels with the CBN hard ceramic bond with the cyclic dressing, and to implement the creep feed grinding procedures with continuous abrasive wheel dressing in cutting in two coordinates applying linear and circular interpolation.
