METHOD OF INTERRUPTED GRINDING Russian patent published in 1998 - IPC

FIELD: deep peripheral grinding of materials predisposed to defects in the form of burn and microcracks. SUBSTANCE: use is made of a grinding wheel rotated and moved relative to the workpiece. The wheel is composed of several elementary n=H/Ho cut-off wheels, where H and Ho - respectively are the heights of the composite and cut-off elementary wheels. The wheel is installed at angle α to the plane perpendicular to the axis of rotation, angle α is selected from condition α ≥ arccos(1-2t/D_o), where t-depth of grinding; Do - outside diameter of cut-off elementary wheel. As the wheel gets dulled and glazed, its dressing is performed at angle α = 0.. EFFECT: effective use of the entire peripheral working part of the tool, enhanced dimensional and common stability, capacity and quality of machining, reduced heat density of the process. 3 dwg, 1 ex
