Kammerer Gewindetechnik GmbH, a manufacturer of thread technology from Hornberg in the Black Forest, now uses a processing machine with robot automation to produce its screw drives. The new machine tool enables automated production processes for small to medium batch sizes. This now gives employees more time for the production of non-automatable pieces from batch size 1.

Since an old production machine at Kammerer had to be replaced, the management decided on a lathe from the CTX 2500 series from DMG Mori with automated support from a robot. The system developed by DMG Mori called Robo2Go enables automated, flexible workpiece handling for small to medium batch sizes. New workpieces are prepared thanks to the simple programming via the DMG interface; teaching the robot is not necessary. The operation is intuitive and dialog-guided. The robot removes the raw parts from a magazine. Both shaft parts and chuck parts can be processed.

The shortage of skilled workers is also an issue at the Black Forest thread technology specialist. “We can now use our staff to produce complex components and small batches down to batch size 1,” says Martin Huber, Lean Manager at Kammerer in Hornberg. “This offers the opportunity to increase output while at the same time having a shortage of personnel.” However, automation also results in challenges for employees: “A stable process and good chip drainage are absolutely necessary for automation,” explains Huber. “Chips that were previously removed by the employee are now a problem and can get into the chuck, for example. This negatively affects the accuracy of the voltage. This is challenging for employees, but also offers an opportunity to improve and stabilize processes. In some cases the process needs to be changed. Alternative tools and cutting values also offer a solution here.”

Trapezoidal screw drives are currently being processed on the new machine. In the future, the spindles for ball screws will also be manufactured in shorter dimensions and in batch sizes of 25 to 100 pieces, with both hard turning and soft turning possible.

Kammerer offers all manufacturing processes for producing threads, including spindles with a thread length of up to 15 m and a diameter of 160 mm. The overall program includes ball screws, ball screws, trapezoidal screws, sliding screws, worms, worm shafts, customer-specific assemblies and complete systems. Kammerer thread technology is used worldwide in machine tool construction and general mechanical engineering, in medical technology, precision engineering, handling automation and robotics as well as in aircraft and automobile construction.
