Abstract (en)
[origin: US4551902A] The device for mounting and removal of polishing wheels comprises a cup-shaped support of partially elastic material and fitted on the mounting face of a polishing wheel. A receiving plate is forcibly engaged within the support by elastic deformation of the cup and rigidly fixed to the end of a driving shaft. A duct formed in the bottom wall of the cup serves to discharge air at the time of assembly or to blow-in compressed air between the cup and the receiving plate for subsequent uncoupling of these two components and removal of the corresponding polishing wheel.
