Automotive Transmission machining solutions

The future of automotive transmission The challenges posed by energy and climate concerns call for lighter and more energy efficient engines with lower material consumption, less scrap and a minimum of carbon dioxide emissions. While electric cars, especially hybrids, are continuously increasing in number, vehicles of all kinds will contain gear boxes for the indefinite future. They will simply become more innovative, in aspects ranging from design and production planning to manufacturing and performance. With 75 years of close partnership with automotive manufacturers around the world,...

Outstanding surface finish Eight-edged smartness CoroTurn® 300 offers effective and high-quality turning for medium to finishing operations in turning centers and multi-task machines. Eight effective edges with excellent heat transfer provide predictable performance and wear. I nveio™ is a true technical breakthrough, providing turning predictability and long tool life along with high strength and excellent wear resistance. With GC4335 in place, there is now a complete grade chain available, off-the-shelf, for productive transmission manufacturing. CoroTurn® 300 features precision coolant...

Milling of gears and splines Quick and easy milling of splines The CoroMill® 171.4 cutter for small modules is easily applied in machining centers, multi-task machines and turning centers, making it possible to machine complete components in one set-up. CoroMill® 172 is another productive disc cutter that enables machining of the whole component in flexible, non-dedicated machines, such as multi-task machines and machining centers, as well as in hobbing machines. • Use CoroMill® 171.4 for module range 0.8–4 • Use CoroMill® 172 for module range 3–10 InvoMilling™ for productive small batch...

Power skiving for flexible productivity Power skiving is a continuous cutting process, much faster than shaping and more flexible than broaching and hobbing. This method allows for machining close to shoulders, which enables greater freedom in designing components. Power skiving is used for the productive mass-production of gear teeth and splines. With power skiving, the complete component can be machined in universal 5-axis machines in one single set-up. Power skiving benefits • High productivity and flexibility • Considerably reduced cycle time compared to conventional machining methods,...

Hard part turning Hard part turning with new-generation CBN grades For anyone working in transmission and hard part turning, there are good reasons to choose our new-generation Cubic Boron Nitride (CBN) grades. The grades' speed capabilities, more secure edge line and consistent tool life add value and result in lower cost per component. Designed to meet the demands of hard part turning, the grades achieve efficient and secure machining with excellent surface finish. Application area CB7105 Continuous cut, smaller depth of cut and smaller chip loads at high speed. CB7115 Continuous to light...

Geometry selection for best productivity The constant struggle for increased productivity balanced with stable and predictable performance continuously drives the Sandvik Coromant R&D team to challenge the status quo. Depending on machine and set-up stability, a selection of three levels of productivity are available: • Standard radius for maximum versatility • Wiper geometry for improved surface finish or higher feed in most conditions • Xcel geometry for high productivity in stable conditions • CoroCut® 1-2 insert with -XB geometry for tightest surface finish tolerances and highest...

Productivity booster An automotive customer initially had a cycle time of 22 seconds and a tool life of 95 components. By implementing PrimeTurning™ both speed and feed could be increased substantially, making the cycle time only nine seconds. The reduced cycle time resulted in a productivity increase of 244% for the customer. In addition, tool life was doubled, from the initial 95 components to 190.
