As a manufacturer of high-performance electric and hydraulic sewer pipe rehabilitation robot systems, Pipetronics GmbH utilises two in-house CNC machining centres fitted with a wide range of Big Kaiser tools and tool holders that are available in the UK from Industrial Tooling Corporation (ITC). With headquarters in the South German town of Stutensee, Pipetronics uses the Big Kaiser range of products for the production of its robots’ turned and milled components.

To ensure complete coverage of all production processes, Pipetronics purchased a Grob G350 five-axis machining centre and a Mazak i400 ST turn-mill centre. Both feature robot automation.

“To mill very close to the clamping device along the spindle, a slim, stable and precise tool holder is required, which is where tool-holder specialist Big Kaiser comes into the picture,” says Rolf Dettinger, head of CNC manufacturing at Pipetronics. “From my previous job, I have significant experience with Big Kaiser spindle tools and Big Daishowa tool holders. After being repeatedly disappointed by the quality of the default chucks used on the Grob, I finally contacted Big Daishowa and they kindly provided us with the Mega Double Power Chuck for testing.”

Seeing the impressive results during the test phase, Dettinger was so impressed that he ordered several Micro collet chucks from the Mega Chuck series for the Mazak machine in addition to the tested power chuck.

“For our application, the Big Micro Chuck collet chucks offer optimal performance characteristics for machining hard-to-reach workpiece areas, where conventional collet systems fail to deliver,” he says. “Thanks to its groove-free collet nut, vibration at high speeds are prevented. The key is that this Big Kaiser micro-collet system is slim enough to implement in all our machining operations.”
