This test arbor is suitable for calibrating your machine spindle or tool presetter. Helps reduce down time and costly repairs, identifies potential problems with spindles and bearings.

BT spindle test bar is mainly to check the accuracy of the machine spindle cones and various CNC machine tools and precision instrument spindle and hole taper check, BT spindle test bar is a standing tool in machine tool manufacturing and repair work, mainly used to check the spindle sleeve Radial circular runout of similar parts, axial movement, coaxiality, parallelism and the accuracy of parallelism with the rail test, inspection rod made of tool steel, after heat treatment and precision machining, the structure has sufficient rigidity.

RicoCNC tooling systems has expanded its line of precision test bars with models for BT30, BT40 and BT50; ISO30, CAT40 and CAT50; and HSK50A, HSK63A, HSK63E, HSK63F, HSK80A, and HSK100A. These test bars are designed for easy and quick confirmation of accurate machine spindle alignment. Regular inspection of the spindle with a test bar can improve tool life by helping operators reduce TIR.
