Abstract
A cutting tool comprising a two-sided cutting blade positionable in a tool holder to form a blade hob. The inventive cutting tool can be used to duplicate the generation action of single or multi-threaded, multi-gashed hobs. The two-sided cutting blade comprises one or more tooth profile shaped cutting teeth located at each end of a cutting blade body. The cutting teeth on respective ends are axially offset from one another. The cutting blade is moved to a number of generating positions to generate the desired tooth surface on a workpiece.
Claims15
A cutting tool for producing gears and other toothed articles comprising:
- a tool holder having an axis of rotation;
- a two-sided cutting blade positioned in said tool holder, said cutting blade having a blade body, a first cutting end and a second cutting end with each cutting end having one or more toothed-shaped cutting profiles, the one or more toothed-shaped cutting profiles on said first end being spaced by an axial offset amount from the one or more toothed-shaped cutting profiles on said second cutting end.
The cutting tool of claim 9 wherein said tip surface is relieved from the front surface to the back surface in a straight or non-linear manner.
A cutting tool for producing gears and other toothed articles comprising:
- a generally cylindrical tool body having an axis of rotation;
- one or more toothed-shaped cutting profiles projecting from said tool body at a first location and one or more toothed-shaped cutting profiles projecting from said tool body at another location, the one or more toothed-shaped cutting profiles at said first location being spaced by an axial offset amount from the one or more toothed-shaped cutting profiles at said another location.
