This bridge-type CMM meets the marketâs demand for an economical & entry-level CMM, sensor and software technology. Designed for general measurement. The SPECTRUM can be configured to meet your specific needs. Key Features: Carl Zeiss RDS-C5 articulating probe holder with our XDT multi-point sensor or Renishaw TP20 touch-trigger. Measure angled features in difficult to reach locations. The articulating probe holder offers +/- 180 degrees of bi-directional rotation and permits indexing steps of 5 degrees reaching 5,184 angular positions for either sensor. CAA (Computer Aided Accuracy) ensures computer-aided error correction of the dynamic deformations of the machine technology. Machine Technology The granite machine table underscores the sturdy construction of this measuring machine. 4-side air bearings from Carl Zeiss ensure more stability and measuring precision. The controller, software, sensors and additional components are ZEISS products and are optimally matched to each other. The computer-independent standard control panel permits manual control via the joystick at a measuring location away from the computer. Speed during CNC operation is controlled via the overdrive knob.
