By Filipp Pachomow. Step by step automation has taken over the various processes in metalwork manufacturing. One application where automation has until now not left its mark is polishing, a very important process in mould manufacturing. But soon that could all change with the RSC compressed air spindle system with a deflection unit from Biax.

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). The aim was to reduce processing times in mould manufacture using new methods. The aim was to polish the mould using the same machine immediately after milling. Also on board: Camaix from Aachen, the specialist for CNC, CAD and CAM technologies, Artifex from Kaltenbach, manufacturers of elastically bonded abrasive and polishing tools and Schweiger from Uffing am Staffelsee, the tool and mould manufacturers. "Thanks to the new deflection unit the contours of the workpiece are now sufficient to achieve a uniform contact pressure on the surface. And that is a prerequisite to obtaining a high surface quality" explained Martin Erle, technical application specialist at Biax.

The RSC pneumatic spindle system with a deflection unit from Biax always ensures a uniform surface contact pressure during polishing and deburring.

Burrs are removed from around 2,500 transmission and clutch cases every day at IDS Casting Service GmbH in Oggelsbeuren. IDS achieves these throughput rates reliably and smoothly with the help of pneumatic spindles sourced from the Biax company. t’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 re...
