Fineblanking

The fineblanking process involves a total of three forces, which distinguish this technology from other punching or cutting processes.

Fineblanking creates smooth, quadrilateral, crack- and burr-free fineblanked surfaces, while the component itself is flat and level thanks to the clamping process. Additional finishing on the contours is generally not required. In industrial series production, this opens up entirely new technical and commercial opportunities. Feintool technology allows extremely complex, ready-for-assembly, multifunctional parts to be produced cost-effectively. Alternative methods exist. But they can only provide results that are “similar to fineblanking”, especially as regards fineblanked surfaces and flatness.

Dual clutch transmissions, continuously variable transmissions or hybrid drives and ever more gear steps: these are just some of the catchphrases defining the innovations and the future of automobile gear boxes. Modern car gear boxes are becoming increasingly compact, lighter and more complex with the aim of reducing fuel consumption. Feintool supports this development with precision fineblanked components, which are used in the latest generations of gear boxes. Modern automatic and dual clutch transmissions contain around 40 individual parts designed as fineblanked and formed components. For example, Feintool develops and produces synchro rings, planetary carriers and torque converter clutch discs. 

Intelligent tool concepts are the basis for successful fineblanking projects. 

This also includes the combination of multiple processing steps into a single press stroke, which significantly increases productivity – at speeds of up to 200 strokes per minute. Feintool uses this integrated approach and an awareness of interdependencies to develop a production concept that lets you get the best out of your resources and raw materials.
