Ballbar Testing


A Ballbar is one of the best tools for checking the contouring accuracy of CNC machine tools. Ballbar tests show how two axes work together to move the machine in a circular path.
The Ballbar can identify a range of machine geometry and motion errors, as well as giving an overall indication of machine contouring performance.
Renishaw software diagnostics enables analysis of specific machine errors including backlash, reversal spikes, lateral play, servo mismatch, squareness, straightness, and scaling errors.

A Ballbar test can be performed on new machine installations to baseline machine performance, or it can be performed at defined intervals to track machine capability and wear.  A Ballbar test should always be performed after a machine crash.
