REST OF GRINDING MACHINE TOOL Russian patent published in 2006 - IPC B24B5/307 B24B19/06 

FIELD: machine tool manufacture, possibly rests of round grinding machine tools for centerless grinding, for example of rolling raceways or beads of outer or inner races of rolling bearings.

SUBSTANCE: rest includes strut in which lower support for compensating weight of article and multi-step self-aligning correction support are mounted. Correction support includes members symmetrical relative to their own rocking axes, namely balance beams and bearing shoes whose positions in support are determined by angles μ₁ , μ₂ where μ₁ - angle formed by radius passing through rotation center of article and rocking axis of bearing shoes and by radius passing through rotation center of article and rocking axis of balance bean of first step; μ₂ - angle formed by radius passing through rotation center of article and rocking axis of bearing shoes and by radius passing through rotation center of article and contact point of supporting surface of one arm of bearing shoe with article. Said multi-step support is asymmetrical relative to axis of last step. At least one member of one step has predetermined angles μ₁ and(or) μ₂ different from angles μ₁ ,_{μ2 of remaining members of the same step.}

EFFECT: enlarged diameter range of worked products, enlarged band of suppressed harmonics.
