QUALITY

The trend towards higher levels of performance has lead to the deveiopment of ultra precision cutting tools of an accuracy known so for only in the use of precision milling tools.

Thickness tolerances of ±0.001mm (±0.1µm) and surface finishes of Ra 0.1µm have become standard.

For highly demanding accuracies such as required in the splitting process of thinnest alumirium or copper foils it is possible today to manufacture tools in guaranteed thickness tolerance of ±0.5µm.

Obtainable manufacturing tolerances of our precision tools

SOFTWARE

To supplement our supply of a complete tooling package as an initial installstion of a slitting line a software package for computer assisted set ups is offered. This software is written tailored to customers needs.

As a special service we can determine the tooling needed based on given slitting parameters.

GRINDING SERVICE

The Geringswalde factory can provide accurate regrinding services in a short turn-round time.

This offers reliable and professional know how from the machine knife manufacturer without the risk of losing accuracy of the tooling.

RESOURCES PLANNING

We can provide special containers and boxes for the storage and transportation of high precision tooling or can recommend specialists in the field.

KSF MICROPLAN

We offer a device for polishing and cleaning of parallel surfaces of circular tools (knives and/or spacers).

The machine has been designed for parts up to 450mm φ and is in conformity with CE-regulations.

RELIABILITY

The constant modernization of manufacturing equipment over the last 10 years has lead to an increase in capacity, which has clearly reduced the delivery time in favour of our customers.

Today, most common knives are available from stock. We aim for our customers satisfaction.

SEMINARS

In addition seminars about slitting belong to our range of customer services.

In such seminars we are transfering our know-how to our customers and we offer them fully fleched package solutions leading to winning margins and competitive advantages.
