Ballbar Testing & Analysis for CNC Machinery

We perform Ballbar testing and analysis on all CNC machinery and CNC equipment. If you need help in determining your root cause of your machining issues and need to help isolate a specific axis, control problem, lubrication problem or problems in other areas a ballbar test might be right for you. Ballbar testing is used as part of many Preventative maintenance PM programs as well as a predictive maintenance tool.

What can a ballbar test do for your machinery?

This is a precision measurement tool that collects axis movement when moving in circular motion. The Ballbar test will measure any deviation the machine makes from a perfect circle, recording data as the two axes work together. Problems with the machine such as squareness, backlash, level, bad ballscrews, bearings, reversal spikes, servo mismatch, stick slip, vibration, and other problems can be determined. Ballbar testing can also be beneficial in finding the optimum feedrate which a machine can run at depending on the size of the circular interpolation.
