The face of winners: (from left to right) Christian Neuner and Jakob Nordmann from Open Mind MIND, with Konstantin Brodowski, Daniel Swoboda and Director of Marketing Tobias Völker from Haimer Those involved in this project took the very limited space conditions into account when clamping with the extra slim and low-vibration Haimer Power Mini Shrink holders.

This, in turn, allowed us to achieve greater depth of cut and a higher metal removal rate.”įor the finishing process, they went with the full radius version of the solid carbide endmill from the Haimer Mill Alu series because of its micro-geometrical properties, which are designed for smoothness and top surface quality. “This allowed us to achieve significantly more rigid clamping and less vibration than we would have had if we used standard tool holders. “We clamped the coated, cylindrical extensions of the Duo Lock tools using the Haimer Power Shrink Chucks,” says Daniel Swoboda. They offer a degree of sharpness with just the perfect balance in terms of abrasiveness and resistance. These fine balanced tools feature superior length repeatability. He specifically chose a four-flute cutter with a corner radius from the Duo-Lock Haimer Mill Alu series. This system consists of carbide tool heads that are connected to different extensions via an extremely stable interface. That’s why Daniel Swoboda opted to use the modular Haimer Duo-Lock tools for the roughing applications. Though already using the shortest tools possible, the application specialists still required tool lengths up to 278 mm. The limited accessibility also impacted the type of tools selected. What’s more, access to many of the parts was extremely difficult, which is why those responsible decided to make the statue in two set-ups, for which a Lang macro grip 5-axis clamp was used as a fixture. The long and thin shape of the delicate tail section was equally difficult to master, as it was extremely sensitive to vibration. Machining of the panther’s head proved especially challenging, in particular the extremely detailed mouth and teeth. As for the milling machine, they chose the linear, 5-axis DMG Mori HSC70 machining center located in the Haimer Application Center, which is ideally suited for precise aluminum machining and excellent surface finish.
That’s why Jakob Nordmann, application engineer at Open Mind, set up camp in Igenhausen, Germany for a few weeks, where he teamed up with Haimer applications engineer Daniel Swoboda to set up the programming and machining infrastructure. Hypermill has lots of functions that allow CAM users to truly put a machine’s power to the ultimate test to achieve the desired goal.” In many ways, the panther analogy very much applies to us.
DMG ENGINEERING SOFTWARE
Manager of Global Engineering Services Christian Neuner explains: “A model such as this one is a great opportunity to put the versatility and flexibility of our software to the test. They showed no hesitation in answering ‘yes’ to the question of whether an application engineer was up for the job of programming the unusual showpiece and joining us on the milling project. Their Hypermill CAM system is widely used in 5-axis machining centres and the company is experienced in programming completely freely shaped contours. In their search for “teammates” for the panther project, Haimer turned to Open Mind, a longstanding partner and CAD/CAM manufacturer based in Wessling, Germany.
DMG ENGINEERING HOW TO
The panther model demonstrates how to efficiently work with difficult, free-form components. Haimer works in very much the same way by incorporating the perfect synergy of its high-tech products with most modern machine tools and the best in class CAD/CAM software.”
Each player must possess excellent technical skills and contribute them into a perfect team. Head of the Haimer application center Konstantin Brodowski sees even greater parallels: “Hockey isn’t just about speed and brute force. The panther is a masterful part showing that 5-axis-milling with its tool holders and solid carbide endmills, can compete with the sport of hockey in terms of speed, power and dynamics. The family company develops, manufactures and sells high-precision metal cutting products, and came up with the idea of milling a panther out of aluminum at their own application center.
DMG ENGINEERING PROFESSIONAL
Haimer, headquartered in Igenhausen, located just 30 minutes from Augsburg, is a proud fan and sponsor of the professional hockey team. The “Augsburger Panther”, a member of the DEL (German Hockey League) are the most renowned ‘panthers’ around.
