Trouble-free despite dirt

The roller table at Haas Maschinenbau GmbH uses energy chain and bearing technology from igus®

Haas Maschinenbau GmbH is a family business that manufactures both individual components and entire machines customised to customer requirements. For a recent customer project, the machine manufacturer designed a 10 metre long roller table that is asynchronously adjustable in width and in which four hydraulic lifting and lowering vacuum platforms were installed. Both roller conveyor halves are driven separately and enable the transfer and removal of caravan roofs that have been milled to size on an upstream CNC machining centre. Once the component has been picked up, additional bends and folds are made along the entire length of the component.
For energy supply, however, the problem was that the entire system generates a lot of dirt, which affects the individual components. The milling machine produces aluminium chips, wood shavings and fine dust from composite materials, which are inevitably introduced into the conveyor system. Due to the long length of the roller conveyor, twisting and turning during the change in width could not be avoided; a high-precision guide system using recirculating ball bearing guides would have led to malfunctions and blockages.
All feared problems could be counteracted by using energy chain and bearings from igus®. The application is in trouble-free operation, which makes the end customer in particular very satisfied today. The customer has no maintenance requirements for the entire motion technology. Furthermore, this is guaranteed with a simultaneous significant reduction in overall costs. The budget could therefore be adhered to and a follow-up system with igus® products is already in prospect.
