ABSTRACT:
A key deburring and polishing assembly for keys which have been cut on a key machine or for other metal elements which have uneven or hanging pieces remaining thereon has a frame having a base member and a front end plate and a back end plate connected on opposite ends of the base member and a cover which encloses the frame, driving mechanism mounted in the frame and fixedly connected to a cylindrical drum for rotating the same which drum defines a deburring and polishing chamber open at one end and can be aligned for operative association with the inner face of the front end wall so that abrading material which can be charged into the deburring and polishing chamber of the cylindrical drum by a suitable charging opening will not escape therefrom but with sufficient clearance to permit small particles to escape. The front end plate has an opening to permit a key or other element to be inserted and so positioned that when the cylindrical drum is rotated the inserted end of the key or other device will lie in the path of the rotating abrading material and thus enable the abrading material to deburr and polish the inserted end of the key or other element.
Additionally, the combination of a key deburring and polishing assembly as above described with a key making machine for driving the deburring and polishing assembly a jackshaft assembly on the key making machine.
