Roturn 400 C turns with consistent high quality
The pipes for these systems are coated steel pipes that have to be threaded on both sides. When looking for a lathe that could produce them quickly and with consistent good quality, one of the companies Donner contacted was KNUTH Machine Tools.“We are already using lots of KNUTH circular saws, lathes, and a drill press and are very satisfied with the quality,” says Donner. Andreas Hendrich, responsible for KNUTH’s sales in northern Germany, responded to Minimax’s requirements directly on site: “We knew that we wanted to provide Minimax with an optimal production solution and at the same time with precision lathing to ensure the reliability and safety of the end customers’ systems.” Hendrich recommended the Roturn 400 C CNC inclined bed lathe, whose heavy-duty inclined bed lathe frame guarantees high rigidity and good chip removal. In addition, the precise linear guides in the X and Z axes ensure high stability and accuracy even under high loads. “It guarantees high process reliability, especially for this sensitive part production,” says Hendrich. With its 15-kW main shaft motor, the Roturn 400 C is capable of high torque in all speed ranges, and the Siemens 828 D basic control meets all current control technology requirements. With the easy-to-use dialogue-oriented user controls, the machine operator can quickly and accurately adjust settings and perform maintenance.
