Core competence fine blanking

Effective processes for demanding components and assemblies
As a specialist in fine blanking and due to our particular know-how, we are able to apply the fine blanking technology in a particularly effective and economical way. As a result of the fine blanking process we supply high-quality parts and assemblies including every surface finishing. We offer you a comprehensive process know-how for component design, the realization of complex components thanks to our own tool development as well as a modern, economical production and flexibility.

In addition to the design and manufacturing of fine blanking tools, we also offer design consulting, fine blanking, forming, hard and soft turning, pointing (clutch bodies) and precision grinding. Our portfolio also includes heat treatments, surface finishing, joining techniques, plastic jacketing and deburring techniques – each service carried out in cooperation with high-performance partners.

Even more precise, even better
In the fine blanking process – in contrast to other cutting and punching processes – triple-action presses ensure more precise dimensional accuracy, improved surface and flatness values, as well as tear-free and cut-free edges of the workpieces. The economical technique allows for the simultaneous forming of components; thus, a time-consuming reworking of the workpieces is no longer required.

For the production of high-precision parts we currently use 14 fineblanking machines from 280 to 1,400 t which can process material thicknesses up to 14 mm and even cut helical gear products with highest quality – 7 of these machines (with 280 to – 700 t) are available at our plant in Remscheid. Through targeted cold forming and precisely defined annealing parameters, the Mendritzki strip steel plants supply the ideal base material for the production of the specific components.

Economical and efficient deburring
In addition to the classic barrel finishing grinding process, we use automated belt grinding and brushing processes. No matter how components have to be deburred, we offer the right technology. In addition to the classic processes such as belt grinding, brushing or barrel finishing, we use highly automated systems that – particularly with large quantities – combine high efficiency with maximum process reliability through guaranteed double-sided machining. This allows us to deburr small and large components just as efficiently as prototypes and large series.

Belt grinding / brushing
We are known for a high level of expertise in the automated deburring of magnetic components with a maximum size of approx. 60 mm x 60 mm. A manual insert and hand pick for “large parts” is possible, too. The position detection and positioning of the components is performed efficiently and precisely thanks to a camera system with a turning station. This way, we can process components with a partial thickness between 2 mm and 7 mm. The maximum throughput is 10,000 parts per hour up to a size of 40 mm x 40 mm. The fully automatic feeding of the raw parts and the palletizing of the finished product by robot makes finova even more efficient.

Economical and precise for high volumes
In the process of double-face grinding components are ground to thickness on both sides and very precisely. The workpieces are successively inserted through the grinding wheels by means of a transport disk. A huge advantage: with the technique of double-face grinding – also called disc grinding – workpieces in large quantities can be reworked economically.
The CNC-controlled surface grinding machines, such as the double-surface grinding machines, are characterized by highest accuracy in the micrometer range and by the ability to cope with high allowances. Double-face grinding results in high surface qualities and defined surfaces.

We specialize in the production of toothed clutch discs, which we sharpen and process using state-of-the-art CNC technology. Modern control and labeling systems ensure traceable and error-free components. We have 5 ultra modern plants for sharpening / demarcating, which exhibit – among other things – position-oriented loading and in-process measuring systems.

When it comes to precise components with smallest tolerances, finova is the right choice. We combine modern automatic turning machines to further process semi-finished parts with individual measuring and testing technology and, thus, ensure safe processes. In addition to the driven tools, our lathes also feature automated loading and unloading as well as partly in-process measuring systems.

We also offer various heat treatment processes in cooperation with our partners. These include quenching and case hardening in multi-purpose chamber furnaces, bainitic hardening in salt bath continuous flow systems, distortion-free hardening in quench hardening plants, inductive hardening and annealing.

For surface refinement, we rely on partners who specialize in corrosion and wear protection processes such as KTL coating, Zi|Ni coating and phosphating. Powder coatings can be applied to the workpieces in every desired RAL color.

Often, only the proper combination of steel and plastic makes the right product. In addition to high-precision steel components, we also supply these as hybrid components with plastic – and just as precisely. For this we work together with strong partners from our network. There are virtually no limits to the choice of materials, not even for fiber-reinforced plastics.
