DEVICE FOR FIXING GRINDING WHEELS Russian patent published in 2001 - IPC

FIELD: abrasive treatment, particularly, fixing the grinding wheel for depth peripheral grinding of materials predisposed for appearance of burns and microcracks. SUBSTANCE: device contains housing mounted on the spindle, wheels in the amount of not less than three which are fixed with radial space to each other on the housing. The wheels are inclined at the acute angle to the surface which is perpendicular to the rotation axis. The journals of the ends of the stepped housing receive face planes provided with rigidly fixed wheels. The face planes are interconnected through springs. The device of control the mutual arrangement of the wheels is made of hydrocylinders. The working spaces of hydrocylinder are formed by the housing and the face plates. The middle journal of the housing receives rigidly fixed middle wheel. The face plates can simultaneously and symmetrically move in the axial direction relative to the middle wheel. EFFECT: enhanced efficiency, quality, and capacity of treatment due to interrupted grinding. 2 cl, 6 dwg, 1 ex
