Kellenberger K-TURN 1000: Revolutionizing Machining with an Integrated Grinding, Turning, and Milling Solution

As of August 9, 2025, Kellenberger, the premium grinding machine brand under the Hardinge Group, has officially launched a groundbreaking machine named the K-TURN 1000. This is not just a conventional grinder, but a multi-functional machining center that, for the first time, integrates turning, milling, and grinding processes on a single platform. The introduction of the K-TURN 1000 marks a significant advancement in the ""Done-in-One"" manufacturing philosophy, promising to deliver superior efficiency in precision and productivity for the precision machining industry.

The ""Done-in-One"" Philosophy: Optimizing Precision and Productivity

The core advantage of the K-TURN 1000 lies in its ability to perform all operations on a complex workpiece in a single clamping. In traditional manufacturing, a part often has to be moved between different machines (lathe, mill, grinder), with each re-clamping operation posing a risk of cumulative errors that reduce overall accuracy. By completely eliminating these re-clamping steps, the K-TURN 1000 ensures the highest levels of concentricity, roundness, and positional accuracy.

Furthermore, this philosophy helps to significantly shorten production time. Eliminating transport, waiting, and setup times between machines dramatically reduces the total lead time. This not only increases productivity but also lowers operating costs, labor expenses, and the required factory footprint.

Technical Analysis and Key Technologies

To realize its multi-tasking capabilities, the K-TURN 1000 is equipped with advanced technologies. The machine features a versatile grinding head that can be precisely swiveled and positioned, enabling external, internal, and face grinding. In parallel, a compact yet powerful turning-milling unit, using a Capto C5 tool interface and equipped with an automatic tool changer, allows for contour turning, drilling, slot milling, and even gear cutting operations.

The entire system is controlled by a powerful Fanuc 31i-B CNC controller, complemented by Kellenberger's intuitive interface software, which simplifies the programming and operation of complex cycles. With a distance between centers of 1,000 mm and a swing diameter over the table of 520 mm, the machine can process a wide range of components, from shafts and machine tool spindles to parts for the hydraulics and aerospace industries.

Market Impact and Target Applications

The launch of the K-TURN 1000 targets manufacturers requiring extremely high precision and components with complex profiles. Key target industries include machine tool building, aerospace, automotive (especially transmission parts), hydraulics, and mould and die production. By offering an all-in-one solution, Kellenberger is helping its customers enhance their competitive edge, meeting the market's increasingly stringent demands for quality and delivery times.

This is a strategic move by Hardinge to solidify its leading position in the high-end machine tool segment, reflecting the trend of technology integration to create smarter and more efficient manufacturing solutions.
