METHOD FOR BAR CUTTING INTO PLATES WITH THE USE OF DISCS HAVING INNER CUTTING BLADES Russian patent published in 2005 - IPC

FIELD: abrasive machinery, particularly devices for bar cutting into plates.

SUBSTANCE: method involves fixing and tightening disc on body; rotating body around its axis; introducing bar into disc orifice for a distance equal to sum of a given plate thickness and width of cut; linear moving bar on cutting blade of the rotary disc; cutting plate from the bar; pulling disc closer to bar; supplying cutting technological means in front of cutting area for cooling cutting blade and behind of cutting area for cleaning cutting blade from products of bar cutting; retracting bar into initial position. Blade pulling is performed during cutting operation by reducing disc dimensions in radial direction by performing uniform blowing gas flow having negative temperature over edge thereof. Blowing is performed along disc perimeter outside cutting area.

EFFECT: increased quality of cut plates due to vibration reduction.
