Destructive pitch measurement of cooling channels in tungsten carbide rods for the measurement of cooling channels in drill blanks developed the CT-9000. The measuring system in conjunction with the measurement software metric and the image processing software profile check allows a non-destructive measurement of slope (swirl). Others including Car Digital Video Recorder, offer their opinions as well. With the 2D measurement software metric plus are performed manually following the special angle 4 C measurements and logs: pitch measurement of the cooling channels, diameter, of the blank Center distance of the cooling channels (Center to Center), maximum distances of the cooling channels and the bore diameter of the cooling channels. Raw rods kidney-shaped cooling passages be performed automatically with the image processing ProfilCheck and compared in relation to nominal values and recorded with: diameter of the blank, width of the kidney-shaped cooling channel, outer radius of the kidney-shaped cooling channel from the Center, inner radius of the kidney-shaped cooling channel of the Centre, distance measurement from the Center to the kidney-shaped cooling channel measurement in degrees of torsion of the kidney-shaped cooling channel to the Centre, area measurement in square millimeters of the kidney-shaped cooling channel. The hardware: The CT-9000 is built on an aluminium base plate. The extremely high-quality 14-step zoom lens is combined with special lighting. The optical system which is mounted on a precision stage is adjusted in Z and X by spindles with a gradient of 0.5 mm or on request with two digital gauges.

The complete optical system with cross table can be moved on the precision linear Pack in Y and fixed. A USB 2.0 is used as a camera camera with 1600 x 1200 pixels. The calibration of the two programmes, metric plus and ProfilCheck is 0.1 mm and certificate by glass scales with Division. The blank is inserted in the prima and shifted in focus. Depending on the diameter Einlegeprismen can also be used here. The clamp is is carried out if required by a U-bolt after successful measurement of the first page of the blank the rotary table is twisted by 180 (with locking pin) and the precision guidance in the correct focal length and carried out the second measurement (measurement angle 4 C in software metric plus). The measurement with the image processing software ProfilCheck must be carried out only on one side. The measurements and documentation are extremely fast and easy to create. As a result, the payback period of the CT-9000 is exceptionally short.
