Class Information
Number: 82
Name: Turning >
Description: (1) This class includes inventions for producing articles of predetermined section, usually circular, by means of cutters brought into engagement with the exterior of a rotating work-piece or by means of cutters revolving circumferentially around and in engagement with that portion of the work-piece to be shaped. It contains mainly metal-working machines, but is not confined thereto, including all such mechanisms of the above-named structure and function as are not specifically classified elsewhere.
