A telping ball bar is a simple, but useful device that provides a quick and inexpensive way to characterize machine tool errors. The device consists of a telping shaft, with precision balls mounted on both ends (Figure 1). The shaft allows the balls to move apart or together along a straight line, but does not allow any other motion.

Why Is Ballbar Testing Important? Ballbar testing is a process of measuring machine tool performance. It uses a ball bearing mounted on a linear guide to produce a circular motion. As the ball moves, it produces data that can be used to assess the machine's performance in terms of accuracy, repeatability, and symmetry.
