METHOD FOR CENTERLESS GRINDING Russian patent published in 2004 - IPC

FIELD: machine tool manufacture, possibly grinding, for example of raceways or beads of outer or inner races of rolling bearings in centerless round grinding machine tools. SUBSTANCE: method comprises steps of mounting article by its surface to be ground onto multistep self-aligning correcting support unit and lower support unit; using first support unit having prismatic shoes, balance beams of first stage and yoke for providing stabilization of rotation axis of article in direction of grinding it; performing grinding at arranging said members of multistep self-aligning support unit with inclination by predetermined angles μ₀, μ₁, μ₂, and arranging lower support unit with inclination by angle β relative to vertical line; selecting values of above mentioned angles according to condition of guaranteed correction of harmonic components of out-off-roundness of profile in preset range of their spectrum. EFFECT: enhanced accuracy of ground surface, namely improved roundness degree of article. 2 dwg
