Gears and splines

Gears

Achieving close tolerance gears in the soft stage is a common challenge.

For mass production of gears in the module range 3–10, an indexable insert cutter is a cost-efficient alternative to regrindable, high-speed steel or solid carbide hobs. For smaller module sizes and smaller production volumes, we recommend disc cutters with full profile inserts and InvoMilling, which is an excellent choice for prototyping.

 

CoroMill® 176

CoroMill 176 is designed for gears in the module range 3–10. Its ability to reach high cutting speeds, combined with user-friendly insert changing, will reduce cycle times, making it the high-productivity gear milling choice.

 

 


Splines

If you are looking for flexible spline milling, disc cutters such as CoroMill® 171.4 and CoroMill 172 are good choices for shorter series. Thanks to the indexable carbide insert design, your component can be machined in flexible, non-dedicated machines, such as multi-task machines and machining centers, as well as in hobbing machines.

 

CoroMill® 171.4 and CoroMill® 172

CoroMill® 171.4 and CoroMill 172 disc cutters offer versatile and time-saving solutions for milling splines in the module range 0.8–3 (CoroMill 171.4) and 3–10 (CoroMill 172).

 


 
Power skiving

Power skiving is used for productive mass-production of gear teeth and splines. Power skiving makes it possible to machine the complete component in universal 5-axis machines in one single setup. The machining cycle time is reduced considerably compared to conventional machining methods, such as broaching, shaping, and hobbing.

CoroMill® 178, PM-HSS, and solid carbide cutters are available in module sizes 0.2–6 (DP 120–4), and CoroMill® 180 indexable insert cutters in module 2–8 (DP 12–3).

 


 
InvoMilling™

InvoMilling is a versatile method for manufacturing gears in modern multi-task machines or 5-axis machining centers, and opens up new, cost-efficient ways to produce geared components without dedicated hobbing machines.

Since the complete component can now be machined with just one setup, in just one machine, overall production times can be reduced dramatically. With the right tools, you can increase cutting data and lower the cost per machined gear wheel significantly.
