Tool manufacturer HAM uses Knoll’s innovative Aerosol Master 4000 ATS minimum quantity lubrication system to achieve high-quality machining results. The ultra-fine air-oil mixture provides cooling for materials ranging from aluminium to titanium while significantly reducing costs.

Minimum quantity lubrication (MQL) is still firmly embedded in many minds as a dirty and stickier process. A biased opinion, strongly contradicted by Raffael Eberle, who together with his parents Petra and Günter Eberle manage the business of the tool manufacturer HAM Präzision: “You can't make such a statement. It comes down to the right MQL system. With the aerosol dry lubrication process provided by Knoll, an ultrafine air-oil mixture is generated that ensures the necessary lubrication and cooling during the machining process. Consumption is minimal; one shot glass of lubricant per hour is enough. No sticking or dirt can arise.”

The trained production engineer knows exactly what he's talking about: “After all, we are focussing intensively on machining as an area of application of our products.” HAM Präzision — Hartmetallwerkzeugfabrik Andreas Maier in Schwendi, Upper Swabia — has been producing solid carbide and polycrystalline diamond tools since 1969. “We have a standard range that covers many applications. But we primarily see ourselves as a solution provider for particularly demanding machining tasks. We help our customers optimise their processes, minimise cycle times and save on tool changes. To this end, we develop special and combination tools, which make up around 70 percent of our sales volume overall.”
