Find The Gear Shaper Cutter That Suits Your Needs
Gear cutting is the process of creating a gear from metal, plastic or wood. It is a complicated procedure that has a few stages such as: hobbing, broaching, machining, shaping, forging, extruding, casting, and powder metallurgy.
A gear shaper is a machine tool used for cutting the teeth of internal or external gears. The name shaper relates to the fact that the cutter engages the part on the forward stroke and pulls away from the part on the return stroke.
The cutting tool is also gear shaped having the same pitch as the gear to be cut. However number of cutting teeth must be less than that of the gear to be cut for internal gears. For external gears the number of teeth on the cutter is limited only by the size of the shaping machine. For larger gears the blank is usually gashed to the rough shape to make shaping easier.
The principal motions involved in rotary gear shaper cutting are as follows:
1. CUTTING MOTION: The downward linear motion of the cutter spindle together with the cutter.
2. RETURN STROKE: The upward linear travel of the spindle and cutter to withdraw the latter to its starting position.
3. INDEXING MOTION: Slow speed continuous rotation of the cutter spindle and work spindle to provide circular feed, the two speeds being regulated through the change gears such that against each rotation of the cutter the gear blank revolves through n/N revolution, where "n" is the number of teeth of the cutter, and "N" is the number of teeth to be cut on the blank.
4. COMPLETION OF CUTTING OPERATION: The indexing and reciprocating motion continues until the required number of teeth with the required depth are cut all along the periphery of the gear blank.
Types of gear shaper cutters
Gear cutters are highly specialized tools, and it is important to invest in one that comes from a trusted and recognized brand. Moreover the cutters can be made accordingly to the clients specifications. Although gear shaper cutters are designed to cut any type of gear in spur or helical and can cut internal or external, you can place an order for different cutter depending on the rest of the components you want to use it with.
If you are interested in cutting internal gears with spline holes and a smaller diameter, then the Shank type sharper cutters can be very effective. The shapers can also be designed in such a way that they are able to cut external gears depending on the applications the gears are to be put to.
Where the external disc type cutters cannot be used, the shaper cutters can be a solution - for roughing and finishing the external gears. It is also possible to design the disc cutters to cut splines, serrations, sprockets and any other involute forms. For chain sprockets, timing gears and other module cutters, there are special gears which can be used to design them. Consequently Gear Shaping Cutters are very vital in ensuring that you have your gears well cut and ready for the job at hand.
