DISPOSABLE GRINDING APPARATUS HAVING AN INTEGRAL MOUNTING HUB.

摘要

a disposable device for grinding, such as wheel (10) with concave centre, intended to be mounted on a threaded spindle (14) of a motorized rotary tool (16).the grinding wheel (10) comprises on one of its sides, and a locking nut (44) and, on the other hand, a flange support (28), both of which are secured in the stack (10) are removable without the use of adhesive, so that the grinding wheel is placed in compression when it is set the operating state of the pin tool and the motor under load of grinding.the nut (44) and the flange (28) are attached to one another by driving one end (52) of the nut (44), in such a way that it is to the outside on the surface of the flange (28). a basic package (60) is set and the wire clamping tool (14) of the motor (16) so as to come into contact with the external surface (38) of a substrate (28) during the operation of the machine (10).in a variant, a pressure cap (90) is fixed to the part (56) projecting to the outside of the nut (44) to come into contact with a shoulder on the pin of the tool unit, during the operation of the machine.
