Device for measuring the contours of parts, CMI-Z25

Metrology Technology Research & Development (Taiwan)

Description

Contour measurement principle:
  • The measurement principle of this instrument is based on measuring rectangular coordinates using X- and Z-axis sensors, displaying the coordinate points of the workpiece surface contour, and transmitting the coordinate data to a PC through electronic components.
  • The obtained coordinate data is then mathematically processed by the software according to the technical task requirements.
Contour measurement functions:
  • Measurements include: horizontal and vertical dimensions, linear distance, radius and diameter.
  • Angle measurement: horizontal and vertical angles.
  • Position tolerances: parallelism and perpendicularity.
  • Shape tolerances: straightness, crown profile, arc profile and circle profile.
  • Auxiliary geometry: auxiliary points, lines and circles.
Technical features:
  • The machine table and Z-axis column are made of natural granite, ensuring stability, deformation resistance and high reliability.
  • The use of high-precision contact sensors along X and Z axes improves automation and enables automatic surface measurement.
  • Key components are made of special alloys and undergo stress-relief treatment, ensuring durability and accuracy.
