HSK63A Spindle Runout Test Arbors Calibration Bar
The HSK63A test bar is for HSK A63 spindle runout testing. It is the precision calibration arbor for static accuracy, also for the calibration of the measuring unit of the balancing machine tool dynamic preset.
The spindle runout arbors offer a quick and easy way to verify that a machine spindle is running true after a crash, machine installation, or relocation, or simply as a periodic performance test.
The spindle test arbor helps identify excessive slop or axial play, a factor that will greatly reduce machine performance and lead to excessive tool wear and breakage. Regular spindle inspection and calibration will ultimately reduce downtime and prevent costly repairs of the machine tool spindle and related bearings over the long term.
The spindle test bar has a lot of different names such as spindle run-out arbor, spindle test mandrels, calibration arbor, runout test bars, round mandrel, spindle taper test bar, test arbor and calibration tool.
