The 2021 Kellenberger Model 100 Universal Cylindrical Grinder defines modern precision grinding with a 39.4-inch distance between centers and a 9.8-inch center height. Engineered with a water-cooled 15.4-horsepower spindle, it delivers exceptional stability and roundness accuracy down to 0.000008 inches. The B-axis swivels through 280 degrees for versatile multi-angle operations, while the workhead, equipped with direct drive and C-axis, ensures precise contouring and repeatable finishes. A FANUC 31i-B control with Kellenberger’s HMI provides seamless automation and real-time diagnostics for both external and internal grinding tasks. Compared to conventional grinders, the Model 100 stands apart with its dual high-frequency internal grinding spindles rated up to 120000 RPM, its reinforced workhead, and integrated Marpos gauging systems. Where traditional grinders rely on operator feel, this system’s intelligent B-axis, automatic balancing, and micro-correction tailstock elevate it into a true high-precision platform capable of micron-level accuracy in production or toolroom environments.
