Mitutoyo Canada Inc. recently announced the availability of the Contracer CV-3200/4500 Series contour measuring systems. These instruments are designed to offer significantly increased productivity, with fast traverse speeds and enhanced accuracy. The new Contracer CV-3200/4500 Series machines feature a precision arc-scale built into the Z1 axis (detector) allowing the arc trajectory of the stylus tip to be read directly, thus minimizing error. Both series use a detector arm that lowers workpiece interference while expanding range in the Z1 (detector) axis. The arm is also equipped with collision auto-stop to assure measurement safety even during high-speed movement. Additional safety features in the joystick unit include a drive speed control knob and emergency stop switch. The Contracer CV-4500 features continuous measurement of both upper and lower surfaces via a double-sided, conical stylus. This continuous measurement data can be used to facilitate analysis of features that otherwise would be difficult to measure, such as the effective diameter of an internal screw-thread.
