Longitudinal cutting

Since 1913 Dienes stands for excellent quality, exclusive know-how and effective innovation. With 6 international sites and nearly 500 employees Dienes is one of the worldwide leading partners for the industrial cutting and the service performances belonging to it like e.g. the professional regrinding of the slitting tools.

Optimization of quality and productivity during longitudinal cutting.

Increased dust production, insufficient tool service lives and cutting edge qualities, time-costly tool positionings - those are the problems with which many machine users are permanently confronted. The use of too old cutting and positioning technologies often does not allow another product quality. Increasing working costs and unused capacities are often topics for machine reequipments or new machine acquisitions.

The technology of longitudinal cutting according to the known procedure is not new but the focused knife use and above all the choice of the right knife positioning system leads to considerable savings, a reliable product quality and a maximized machine use.

The effectiveness of an automatically operated longitudinal slitting plant does not only depend on automated individual processes but on an optimal design of single components.

We dispose of about 1200 different types and designs of slitting systems. The knowledge on a cutting tool's correct design for a special application has improved considerably explaining the high number of systems in recent years. It starts with the geometric design of the cutting tool and follows onto the parameters material, tool hardness, measurements, position, tolerances and surface quality. All those parameters can and have to be optimized for a special design.

The cutting tools for high tech processing machines, i.e. machines that have to be used to their full capacity because of high investments, should be optimized in a way that they support the machine's maximum productivity.

Experience shows that it is often cheaper to use expensive and abrasion-proof cutting tools with a longer service life.

For high performance machines the use of bottom knives with tungsten carbide inserts in combination with top knives made from powdered high performance speed steels is gaining more and more acceptance.

The experience of using these materials for years has been showing that the high tool costs are quickly amortised due to a higher service life and consequently higher level of capacity.
