Coordinate Measuring Machines

High-Precision-Co-Ordinate

Additional rotary axis for high precision co-ordinate measurement machines

Precision rotary axes specifically developed to increases the flexibility, productivity and efficiency of your CMM.

Typical applications include:

  • Increase your CMM’s application range and effective measuring volume, flexibility, productivity and efficiency. Significantly reduce inspection times.
  • Simplify the measurement of symmetrical or prismatic components such as camshafts, crankshaft, gears and aircraft engines.
  • Scanning or touch probe applications.
  • Simplifying your measuring procedures and part programming.
  • Stylus configurations become easier with fewer stylus systems required.
  • Travel paths are shorter leading to reduction in temperature influences.
