Solid machine table with reinforced machine bed provides very high static and dynamic rigidity and stability

Automatic indexing axis 1° with high positioning accuracy

Hydrostatic guides in all main axes for maximum shape accuracy in sanding tasks

THE PREMIER CLASS FOR THE HIGHEST DEMANDS

The KELLENBERGER 1000 series was developed for the high demands of precision production of prototypes as well as small and medium series, e.g. in tool and mold making, the automotive and electrical industries and the aircraft industry. The solid machine table with the reinforced machine bed provides very high static and dynamic rigidity and stability, a prerequisite for high precision.

With center heights of 200/250/300 mm, center widths of 600/1,000 mm, generous X-axis strokes of 365 mm and Z-axis strokes of 1,150/1,670 mm, the KELLENBERGER 1000 covers a wide range of workpieces weighing up to 300 kg. The automatic 1° indexing axis with high positioning accuracy and the direct-drive internal grinding spindles up to 60,000 rpm are further features.

The KELLENBERGER 1000 is equipped with hydrostatic guides in all main axes for maximum shape accuracy in grinding tasks with interpolating axes. The B-axis has a direct drive. The turret grinding head swivels around three times faster and positions with an accuracy of less than one angular second. This reduces non-productive times and thus increases productivity, especially when processing requires the swiveling in of different grinding wheels. Over 30 grinding head variants with external and internal grinding spindles are standard on the KELLENBERGER 1000.

Operator guidance is via an intuitive 19″ touchscreen interface on the latest FANUC 31i-B CNC control system. The innovative BLUE Solution software enables even inexperienced operators to program quickly and intuitively.

FEATURES AND OPTIONS

The new KELLENBERGER 1000 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 1000 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 1000 is equipped with the FANUC 31i-B:

  • FANUC 31i-B 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
