Our customers are continuously looking for innovative ways to improve their processes. As part of a large steering knuckle project, our challenge was to develop a concept to have eight or more parts on each fixture. Ahaus accepted the challenge!
Our engineers found innovative ways to achieve this by integrating the horizontal CNC machine tool pallet into the tombstone. In addition, they had to construct the tombstone of a special type of aluminum to achieve the machine tool weight restriction, and to handle the rigidity required for machining. This involved our use of Finite Element Analysis (FEA) to understand the effects of drill thrust and deformation of the tombstone during the machining process.
Once the engineering was complete our focus then shifted to achieving the tolerances required to produce the pallet features acceptable for the machine tool industry. In addition, the requirement involved each of the fixtures being within a few thousands of each other, so the customer had the complete flexibility to move fixtures from machine to machine without major machine offset issues.
The result was over 40 highly engineered and manufactured fixtures delivered on time, commissioned both on our floor and on the customers floor ready for production.
