The CT550 is based on the same machine concept as the CT450, but is designed for larger and longer workpieces. The spindle set-up, with up to 3 HF grinding spindles in a linear arrangement, can be optimally designed to meet customer requirements. The ideal grinding machine for internal, face, thread and taper grinding on long workpieces up to approx. 650mm in length, e.g. for the machining of the ends of machine spindles.
