In the peeling machines from the german company Schumag, the outer shell on the steel professional bars, after passing through the professional rolling mill, is taken away. Steel bars with diameters between 5 and 450 mm are peeled.
Feeding industrial rollers professional guide the bars into the turning operation. They have to maintain a continous feed rate of the steel bar with cutting forces up to 100 000 N. The feeding rollers are locked to the drive industrial shafts with, ETP-HYLOC, a hydro-mechanic locking element from ETP Transmission AB, Sweden.

Potatoes, apples, carrots – they can all be peeled with the help of a knife. The knife edge cuts easily through fruit and vegetables. A much tougher job to do, the Peeling Machines from Schumag in Aachen, Germany has. The life time of the feeding rollers very much depends on the material of the bars and how the rollers are used. The rollers have to create and maintain the necessary feed rate into the machining process also at cutting forces of up to 100 000 N (when using high tensile steel material). Because of this the surfaces of the rollers gets a continous wear and needs to be replaced frequently.

As a consequence of the maintenance work there will be frequent service stops which creates down time and loss of professional production. In comparison with mechanic clamping elements with many screws the hydraulic type will save a lot of time. The feeding rollers are clamped with a hydro-mechanic hub-shaft connection, ETP-HYLOC. This clamping unit from ETP Transmission is very easy to operate for fastening and loosening. This creates a good start for minimizing the down time when changing the feed rollers.
