High Performance Gear Milling

By Christer Richt -April 10, 2012

As demands for quality and efficiency increase, Sandvik Coromant responds with new designs, materials, and tooling for enhanced gear milling productivity.


Sandvik saw the need expressed by the industry for a performance shift in gear milling around 2005. At that time, high-speed steel (HSS) tools were being replaced with newly developed, state of the art indexable insert tools based on modern cemented-carbide grades, along with new insert and cutter body designs. Gear milling is changing along with machine tool and software technology, as well as industry applications.


With the new CoroMill 176 hob concept, Sandvik has taken a very large step forward in gear milling technology and performance. A higher level of tool precision and rigidity has been achieved through a new patent-pending interface between insert and tool. The resulting stability also enables much higher metal removal rates, while also generating good surface quality. The possible material removal rates are   completely new to the gear milling industry. It is  good news that it works both on newer machines and older ones. The output can double or in some cases even triple output with the new 176 cutter. The Coromant Capto tool holding concept is also recommended to add strength and stability to gear milling tools.


New gear milling solutions  starting with module sizes from 3 up to 30 are now available from Sandvik. These include transmission components in equipment such as wind power, mining, marine, industrial gearboxes, agriculture, land moving, and heavy vehicles.


The question or doubt. Can the tight precision demands for high-speed transmissions, such as for heavy vehicles, really be met with indexable insert tools?


 The standard that working well is solid, precision-ground HSS tools. Now Sandvik is able to meet quality 9, according to DIN, —and under favorable conditions, even quality 8. This level is required before heat treatment of gears. Part of this comes down to the fact that the tools are delivered with inserts mounted and with a measurement protocol according to DIN 3968. Subsequent insert indexing then requires a clean environment and skilled people to consistently reach these levels. The motivation in the industry to now change from solid HSS tools to indexable insert tools is higher productivity, increased tool life, and elimination of the logistics surrounding HSS tools for re-grinding and re-coating.


What will be the future offerings of Sandvik Coromant within gear milling?

Today  hobbing from module 4 up to module 18 is available. At the end of 2012, the ambition is to cover the area from 3 up to 30 with indexable solutions. Disc-type milling cutters will be available from module 3 up to module 40. With the InvoMilling method,  even a wider range will be available. 

Industry the opportunity can take full advantage of the CoroMill 176 concept, which is being made available from module 3 to 9. There is a huge savings potential with the application of this concept. In most cases around 50 percent time savings can be achieved compared to existing solutions used in the industry, and in some cases even 80 percent savings have already been achieved. Moreover, these results are reached with lower tooling costs, making the transition to indexable insert technology very advantageous.
