Easily achieving throughput rates of 150,000 cases

It’s a process that’s repeated every day in Oggelsbeuren. Cast by Albert Handtmann Metallgusswerke GmbH in Biberach, the die-cast aluminium components – destined for Mercedes A- and B-Class cars – are delivered to IDS, deburred and then moved on. The company uses four of its own automatic robot cells in two daily shifts along with four pneumatic deflecting spindles manufactured by the Maulbronn-based Biax Schmid & Wetzel GmbH & Co. KG to achieve these throughput rates. Biax is certain that it was able to offer an ideal and cost-effective solution to the task that IDS faced given the operating hour rate of a machine tool and the time it would take to remove the burrs from the cases by hand – and especially in view of the large throughput rates that the company was required to realise. When they arrive, the cases are first machine-blasted with stainless-steel filter-free blasting materials before they are transported by conveyor belt to the four deburring stations. The spindles used during this stage of the work are fixed in position while the robots guide the components through the process.

The art of scraping

Young people in particular are only familiar with scraping from the stories they’ve heard from older colleagues. The task, which also requires great strength, is to create very small depressions in the micrometre range on the machine guide way surfaces in order to ensure sufficient lubrication and to reduce the loads that the guides need to absorb and so considerably increase machine life spans.

Automated Polishing

The experts for pneumatic tools and spindles from Biax, a trademark of the Swabian family-owned company Schmid & Wezel from Maulbronn, have brought to the market the modular pneumatic spindle system„ RSC“ with a deflection unit that could fundamentally change the polishing and refinishing of surfaces. The system can be used both in CNC machining centres and with robots. The spindles can be changed automatically. In a machining centre the compressed air supply is fed through the coolant channel. Biax developed the innovation as part of the „IntegFINISH“ project of the Stuttgart Fraunhofer Institute for Production Technology IPT, who provide funding from the Federal Ministry of Education and Research (BMBF) within the framework of the support measure „SME Production Research Innovative“ that was supervised and managed by the Project Management Agency Karlsruhe (PTKA).
