HEULE was selected to provide the technology for a challenging project with a French foundry. The company also owns numerous cutting machines and carries out additional assembly work. The customer is a long-standing partner in industries such as wind energy, mechanical engineering, shipbuilding, transport, the automotive industry and aerospace.

For the extremely large workpieces, backward countersinking is a common issue. In the example described below, two methods have so far been used to machine the countersink. First, a relatively weak eccentric tool (with an effective length more than 80 mm, roughing/finishing) was used. Second, a manual screw-on backward countersink was used, which in itself introduced critical safety implications. Both methods resulted in long machining times, which led to high process costs for the customer.

Together with HEULE, a solution was developed which is extremely reliable and considerably reduces the machining costs for the customer.
