What was the result? "No one among the customers had completely manufactured the benchmark mold insert on a single machine," he says. But that is precisely what Rotzoll and Schadeck did, with five axes in two set-ups. They did it on an RXP 601 DS in the Röders technical center, which, like all machines from this manufacturer, is known for its high dynamics and accuracy. Because good tools only run optimally if the machine can do the same," says Röders Sales Manager Oliver Gossel, who presented the features of the new RMS6 control generation in a separate part of the workshop program. The machines are, therefore, extremely rigid, vibration-resistant, and have a sophisticated temperature management system. Also critical is the high-speed control response, known as racecut. This means that the target/actual comparison takes place 32,000 times per second, resulting in a higher surface quality and the possibility of further machining reductions. "We use these 32 kHz controllers in all three control loops, i.e., position, speed, and current," the doctor of engineering emphasizes. This makes us twice as fast as our competitors in terms of control.
Going back to the example workpiece, most machining examples were produced before the workshop. All these steps were then explained in detail during the presentation. This included fundamental issues such as the advantages and disadvantages of hard machining, especially hard roughing. Or when and under what conditions die-sinking and wire EDM can and cannot be dispensed with according to the current state of the art. Highlights were also shown live on the Röders machine. For example, the hard drilling of the H7 with the new MOLDINO micro drills of the EMSBH-ATH series for the ejectors. Or achieving the necessary cylindricity or angular tolerance for the walls, i.e., the lateral sealing areas demonstrated in Soltau using the still less known groove milling process.
