Koba Q3 Ball Cube

A quick monitoring system for CMMs (coordinate measuring machines)

Range of Application

​

  • The Q3 Ball Cube provides 28 different combinations of distance between the centers of the spheres. Evaluation of these measured distances represents the accuracy of the CMM.

  • Fast measuring cycles allow monitoring with little impact on the availability of the CMM.

  • If the Ball Cube is used as a monitoring standard, a calibration is unnecessary. In this case the results from rotational monitoring measurements are referred to the initial measurement of the cube after carrying out a complete calibration of the CMM.

  • Use of the Q3 Ball Cube can reduce the costs of inspection equipment monitoring significantly. Re-calibration intervals for CMMs can be clearly extended as long as the ball cube inspection does not show any unacceptable deviations.

Design Features

​

  • Extremely rigid carbon fiber tube construction with stainless steel angle joints for short- and long-term stability.

  • The specially manufactured carbon fiber tubes are free from any variation in length caused by humidity and provide maximum stiffness with low weight.

  • The combination of carbon fiber tubes and stainless steel angle joints guarantees a low coefficient of thermal expansion.

  • The probing elements are highly precise ceramic balls of AI2O3.

  • Low weight and easy handling

  • Evaluation software is also available.
