What is a ballbar test?
A ballbar test monitors machine tool spindle movement as it follows a programmed circular path and compares the machine path to an imaginary perfect circle.
How does a ballbar test work?
The machine does a circular interpolation around a fixed point, usually on the machine table, and the telescoping ballbar measures any deviation between the fixed point and the spindle.
After the test is complete, the software compiles this data and calculates the machine criteria such as, backlash, squareness, and machine positional capability.
Can ballbar testing be done on lathes?
Lathes can be tested, but are trickier than horizontal or vertical milling machines due to the limited space within the machine and ability or inability to travel over center.
