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.
By using the HEULE tool system, the customer saves at least 10 hours machining time per workpiece. The SOLO2 enables a massive optimisation of the process time and dramatically improves health & safety in the workplace for all employees.
The customer is very satisfied with the implemented solution. The reverse machining process was optimised and a significant improvement to the tool life achieved. The customer intends to contact HEULE for future reverse countersinking machining projects.
