Energie- und Ressourcenverbrauch im Focus der GrindingHub

von Angelika Albrecht

Nicht erst seit dem Russland-Ukraine-Krieg setzen steigende Energiekosten das verarbeitende Gewerbe unter Druck. In Deutschland werden schon länger die höchsten Industriestrompreise Europas gezahlt. Zugleich muss sich jedes Unternehmen der Herausforderung stellen, CO2-Emissionen deutlich zu reduzieren und ressourcenschonend zu produzieren. Das trifft auch die Schleifbearbeitung. Ob auf der jüngsten digitalen Schleiftagung des Werkzeugmaschinenlabors WZL der RWTH Aachen oder auf der im Mai stattfindenden Fachmesse GrindingHub in Stuttgart: Branchenexpertinnen und -experten beschäftigen sich intensiv mit der Frage, wie entlang der Prozesskette Einsparungen beim Energie- und Ressourcenverbrauch zu realisieren sind.

Neben den steigenden Energie- und Rohstoffkosten haben auch gesetzliche Bestimmungen und erweiterte Kundenanforderungen maßgeblich dazu beigetragen, den Stellenwert der Energieeffizienz in der Schleifbearbeitung zu erhöhen. Das Schleifen gilt innerhalb der Prozesskette als energieintensives Fertigungsverfahren, da ein vergleichsweise geringes Werkstückvolumen mit hohem Aufwand zerspant wird. Verbesserungen in der Ökobilanz sind jedoch alles andere als trivial, können oft nur in kleinen Schritten oder in der Peripherie der eigentlichen Fertigung realisiert werden.

Über die GrindingHub 2022 in Stuttgart

Vom 17. bis 20. Mai 2022 findet erstmals in Stuttgart die GrindingHub statt. Sie ist die neue Fachmesse und das neue Drehkreuz für die Schleiftechnik. Ausgerichtet wird sie, künftig in einem Zweijahres-Turnus, vom VDW (Verein Deutscher Werkzeugmaschinenfabriken), Frankfurt am Main, in Kooperation mit der Messe Stuttgart und der Schleiftagung sowie in ideeller Trägerschaft des Industriesektors „Werkzeugmaschinen“ von Swissmem (Verband der Schweizer Maschinen-, Elektro- und Metallindustrie).

Die Schleiftechnik gehört in Deutschland zu den Top-4 Fertigungsverfahren innerhalb der Werkzeugmaschinenindustrie. 2021 hat die Branche, laut Schätzungen des VDW, Maschinen im Wert von 805 Mio. Euro produziert. Gut 80 Prozent gingen in den Export, davon etwa die Hälfte nach Europa. Die größten Absatzmärkte sind China, die USA und Italien. Für den Weltmarkt liegen dem VDW Daten bis einschließlich 2020 vor. Unter den Top-Produzenten führen China, Deutschland und Japan die Weltrangliste an. Weltweit produzierte die Schleif-technik 2020 Maschinen im Wert von 4,3 Mrd. Euro.
