When we carry out Ball Bar Test on CNC Machine Services in Ahmedabad, our focus is on understanding how a machine behaves when asked to follow a perfect circular path. Just a few errors can reveal quite a bit of a backtrack, mismatch of the servo, wrongly aligned geometry, or even reversal of an axis. Machines that are running daily and have been relied upon at {companyName} for our work, seem to be quite stable superficially, but in fact, the hidden motion errors slowly but surely become bigger and finally, they influence the accuracy of the part. The ability of the ball bar setup to convert circular motion into measurable data helps us interpret the true health of a CNC system without dismantling or interrupting production for long durations.
