KELLENBERGER
K1000
THE PREMIER CLASS FOR THE HIGHEST DEMANDS
The KELLENBERGER K1000 universal cylindrical grinding machine sets new standards for precision and versatility because it meets the rigorous demands of prototype production as well as small to medium series. It is particularly suitable for industries such as tooling, automotive, electrical, and aerospace. Since it is designed for both durability and accuracy, its solid machine table and reinforced bed provide exceptional static and dynamic rigidity. This combination ensures reliable performance in high-precision applications.
With center heights of 200/250/300 mm and center widths of 1,000/1,600 mm, the KELLENBERGER K1000 is highly versatile. It can accommodate a wide range of workpieces weighing up to 300 kg. Moreover, the generous X-axis strokes of 365 mm and Z-axis strokes of 1,150/1,670 mm further expand its capabilities. addition, the machine offers a high-resolution, high-precision and directly driven hydrostatic B-axis, while the directly driven internal grinding spindles with speeds of up to 90000 rpm are further
highlights
Because the KELLENBERGER K1000 is engineered for maximum shape accuracy, it is equipped with hydrostatic guides on all main axes, which ensure outstanding precision. Additionally, the direct-drive B-axis and the turret grinding head swivel three times faster than conventional systems. This significantly increases productivity while simultaneously reducing non-productive times. This design is especially advantageous when multiple grinding wheels need to be used during the same operation. Moreover, with over 30 grinding head variants, including external and internal spindles, the machine offers unmatched flexibility for complex grinding tasks.
User-friendliness is also a key advantage of the KELLENBERGER K1000. For example, the 19″ touchscreen interface, which is powered by the advanced FANUC 31i-B CNC control system, ensures intuitive operation. Furthermore, the innovative BLUE Solution User-Interface allows even inexperienced operators to program and execute grinding tasks both quickly and confidently. Thanks to this seamless integration of advanced technology and user-centric design, the KELLENBERGER K1000 consistently delivers top-tier performance while also optimizing productivity.

FEATURES AND OPTIONS
The universal cylindrical grinding machine KELLENBERGER K1000 universal internal cylindrical grinding machine combines functional design with high-precision technology. Hydrostatic guides guarantee maximum dimensional accuracy for grinding tasks with interpolating axes.
High positioning speeds and accuracies are guaranteed by direct drives for the rotary axes. Generous X- and Z-axis strokes in combination with the platform concept for grinding head positions and dressing systems ensure universality and enable application-specific configurations.
The proven integral transport concept (hook machine) has been retained and reduces the machine’s commissioning times and ensures a compact installation space. Durable hydrostatic guides and energy-efficient concepts guarantee a high level of investment security.
The KELLENBERGER K1000 can be extended with the following components to further increase production capacity:
- Increased coolant pressure up to 10 bar
- Interface for fire extinguishing system
- Automatic door drive
- Replacement aid for grinding discs and tailstock
CONTROL AND SOFTWARE
The KELLENBERGER K1000 is equipped with the FANUC 3i-B:
- FANUC i-F Plus with 19″ touch display
- Intuitive operation thanks to BLUE Solution with OBJECT Guide and ISO Guide
- Clear, self-explanatory screen pages
- Integrated technology calculator
- Online operating and maintenance instructions
