Gühring tools milled a Bond car from solid material
When you bring together the three best products, you get the perfect process. Gühring and Blaser have combined a high-quality MQL oil with a solid carbide corner radii milling cutter for aluminium machining and an MQL tool holder. The result showcases the advantages that collaborative engineering can yield.

So, Blaser turned to Gühring, with whom the company has a long-standing, close working relationship. Previous projects had already shown that: “The coolant ducts in our tools have the perfect cross-sections to allow the oil to be transported well,” says Michael Gnatkowski, Sales Manager for the Automotive Sector at Gühring.

The RF 100 A
A particularly important factor for the machining of the Aston Martin: The nanopolished cutting edges of the RF 100 A enable low-vibration milling thanks to their micro support chamfers, thereby creating the ideal surfaces. This combination of polished cutting surfaces, a carbo-coating and targeted MQL internal cooling is the ideal prerequisite for machining even sticky aluminium alloys.
Economical and sustainable
MQL cooling
In order to get the perfect performance from this tool, the experts at Blaser defined the ideal interaction between air pressure and oil quantity for the cooling lubricant. This mix is transported through the tool’s IC channels directly to the cutting edge and workpiece surface, where machining takes place. Only as much oil as necessary is used here. This is where the benefits of MQL technology come to the fore: The application is very clean and cleaning is kept to a minimum. By saving oil, disposal processes are also eliminated, which makes sense in terms of sustainability.
In MQL technology in particular, tool holders also play a decisive role as an interface between tool and machine. So, for the Aston Martin, Blaser used an MQL clamping chuck for single-channel systems from Gühring’s GM 300 range.
The best products combined
Aleksej Wahnsiedler, Head of Industrial Partnerships at Blaser, also sees the project as proof of the perfect symbiosis of tool and cooling lubricant: “We are combining the advantages of both systems, thereby enabling us to generate a much bigger benefit.” This advantage is reflected particularly in better surfaces and longer tool lives. In this technological incentive, Wahnsiedler sees the common ground between the two companies: “That together we generate the added value that the customer is looking for.”

Maximum tool lives in aluminium
How real progress emerges from challenges is demonstrated by Dörr together with Gühring: By using the PKD Diver from Gühring, the company from Sankt Augustin quadruples tool life, reduces tooling costs, and elevates the surface quality of its components to a new level.
System 208 enhances stability
Unattended night shifts without risk: Veile Feindrehteile significantly increases process reliability and tool life in stainless steel machining with System 208. The result: stable processes, less scrap, and more cost-efficient production.
Mastering VA threads with ease
Decommissioning nuclear power plants demands maximum precision—especially for stainless steel threads. Weisser Bärwinkel relies on Gühring’s Pionex to master even tough materials. The result: more stable processes, longer tool life, and higher productivity.
