FIELD: machine building.
SUBSTANCE: invention relates to abrasive processing of articles and can be used in grinding machines for the complete processing of articles, in particular gear wheels for drives, on the same machine. Grinding machine contains the headstock of the product and two grinding heads. First grinding head has two grinding spindles with a grinding wheel for grinding the first and second flat, as well as non-flat external surfaces. Second grinding head has a grinding spindle with a grinding wheel for grinding the central drilling of the product. Second grinding head further comprises a clamping device, in particular in the form of a clamping mandrel, which grasps a drilling clamp in the drilling after grinding it clean. First, the first flat outer surface is grinded on one side of the article and the drilling surface is at least periodically parallel in time. Then, the clamping of the article is carried out by means of a clamping device in drilling with the release of the article from the clamping of the product by bag. Grinding of the released second flat outer surface is performed.
EFFECT: complete grinding of the product on one machine is ensured and the accuracy of its manufacture is increased.
