ABSTRACT:
BACKGROUND OF THE INVENTION
The invention relates in general to the field of polishing techniques and, more particularly, to the polishing of metal materials. Specifically, the invention relates to a technique for polishing aluminum, stainless steel, and brass.
Increased metal use and rising costs of metals have caused focus to be placed on the refurbishing of metals through polishing. Generally, conventional metal-polishing techniques do not allow for the capability to effectively polish a detailed and ornate metal object in a consistent fashion because of hard-to-reach comers and insets. Thus, it would be beneficial to have a metal-polishing technique that is capable of overcoming the shortcomings of conventional methods.
SUMMARY OF THE INVENTION
The present invention relates to a technique for polishing metal objects such as, for example, those made of aluminum, stainless steel, and brass. The technique employs a metal-polishing apparatus which includes a double-jointed arm assembly and a table assembly. The arm assembly includes a brush assembly, a handle, and an actuating device. The double-jointed nature of the arm assembly advantageously allows an operator to effectively polish a detailed and ornate metal object. The table assembly has a frame, a rotatable table-top assembly, and a mechanism for securing the metal object. The metal object to be polished is placed on the tabletop assembly and allowed to rotate with respect to the frame. The present invention also relates to the preparation, polishing, and post-polishing methods employed with the metal-polishing apparatus. The present invention enables aluminum, brass, and stainless steel objects to be effectively polished, and therefore refurbished, by removing a significant amount of damage (i.e., scratches) from the metal object.
