Die Produktion muss laufen

The company, which is located in Großmehring near Ingolstadt, has been operating under the name Schabmüller Automobiltechnik GmbH (SMI) since 2003. Before this, the company, founded in 1978 by Franz Schabmüller, was active in the field of special vehicle construction. In 1988, the company entered the automotive supply industry. With the machining and assembly of cubic engine and chassis parts, Schabmüller became a service provider for the automotive industry.

Nowadays, with around 150 employees, Schabmüller is a premium supplier, particularly for automobile manufacturers with high production volumes. Schabmüller can include Daimler, Audi/Porsche and Jaguar/Land Rover in its list of references. However, the most important customer is the VW Group, for which SMI has commissioned its largest plant to date for the production of cylinder head covers. The plant contains 16 machining centres, 26 robots and a number of peripheral machines for downstream machining steps. SMI produces ASM cylinder head covers here for the customer. These consist of a left and right cylinder head cover for the VW 3.0 litre V-group engine, fully assembled with camshaft bearing covers. Over 320,000 sets are produced annually.
 

Before large-scale series production really took off, SMI produced solely with stand-alone machines: One job at a time was processed manually on a machining centre with one worker. When SMI then received an order in 2013 to manufacture bearing frames for the VW Group, which were to be produced in a quantity of 970,000 parts, manufacturing had to be reorganised. “It was clear to us that the tool volume would no longer be manageable for us if we equipped seven or eight machines for the same order”, Häckl explains. “It would have been difficult for production management to keep an eye on the quality of the tools and to follow their reconditioning in terms of deadlines. The production must go on and not stop because a tool is missing somewhere.”

But that’s exactly what had happened in the past. For example, five drills were used up in one night, and the early shift started the day with one last remaining tool. Nobody understood what happened. In other areas, a lack of systematic tool withdrawal resulted in the fact that worn tools ended up in the drawer together with new ones, leading to bottlenecks since this had not been recognised in time. Managing Director Häckl is clear: “Due to this lack of verifiability of tool removals, we kept having huge problems in production.” 
 

Toolmanagement Dienstleistungen sind maßgeschneidert auf die Bedürfnisse des Kunden. Bei Schabmüller umfasst das Komplettpaket die Disposition der Werkzeuge, ihre Voreinstellung, Ausgabe und Wiederaufbereitung, technischen Support der Serienfertigung, Werkzeug- und Taktzeitoptimierungen sowie Standzeitoptimierungen. Die Werkzeugausgabe ist zentral in der Fertigung platziert. Neben einer Reihe von horizontalen Schubladenschränken aus dem UNIBASE­-Programm hat MAPAL bei Schabmüller auch Vertikalschränke installiert. Deren hohen Schübe bieten sich vor allem für große Komplettwerkzeuge an. 

Rund 90 Prozent der von SMI benutzten Werkzeuge sind projektbezogene Sonderwerkzeuge. „Diese Sonderwerkzeuge setzen wir ein, um möglichst kurze Taktzeiten zu erreichen“, erläutert Michael Stockbauer, Anwendungstechniker und Toolmanager bei MAPAL. „Mit Standardwerkzeugen würde man diese Zeiten nicht schaffen.“ Zusammen mit Kollegen ist Stockbauer drei bis vier Mal pro Woche vor Ort in Großmehring. Wenn ein neues Projekt eingefahren werden soll, ist MAPAL sogar täglich im Haus.
