BT Test Bar

Spindle test bars are a quick and easy way to verify the runout and alignment of your machine’s spindle after a crash, after the machine has been moved, or as a periodic performance check. Excessive runout and axial play in a machine tool spindle are the major causes of excessive tool wear and tool breakage. Use one of our high-precision spindle test bars to verify that your spindle is running accurately, to ensure consistent parts and a stable production environment.
