FIELD: machine building.
SUBSTANCE: invention relates to machine building and can be used, for example, in bearing industry for grinding of shaped working surfaces, in particular, rollers of bearings. Machine comprises bed with two pairs of guides, table that can reciprocate along longitudinal guides, on which there is device for fixation and rotation of processed part and device for straightening grinding wheels. Both pairs of guides are turned relative to longitudinal guides at an angle αand are installed mirror-like relative to each other. On each pair of unfolded guides there is a support, a grinding head with a spindle and a grinding wheel and mechanisms for supply and compensation of grinding wheel wear. Grinding heads are made rotary around axes parallel to axes of grinding wheels rotation.
EFFECT: higher accuracy of grinding of end shaped surfaces of machined parts with provision of their equal size along length.
