Performance Description
The BT spindle test bar is primarily used to verify the precision of machine tool spindles' tapers, as well as to check the taper fit between the spindles and bores in various CNC machines and precision instruments. A standard tool in both machine tool manufacturing and repair processes, this test bar is especially designed to assess the radial runout, axial play, coaxiality, parallelism, and alignment with guide rails of spindle sleeve components. Made from high-quality tool steel and rigorously heat-treated and precision-machined, the test bar boasts exceptional rigidity while maintaining a lightweight design, ensuring a taper fit accuracy exceeding 85%. Commonly available spindle specifications include BT, BBT, HSK, ISO, SK, and CAPTO, among others.
