Digital Indicator

Digital Indicator●To check for runout when fitting a new disc to an automotive disc brake.

Runout can rapidly ruin the disc if it exceeds the specified tolerance (typically 0.05mm or less). ●In a quality environment to check for consistency and accuracy in the manufacturing process. ●On the workshop floor to initially set up or calibrate a machine, prior to a production run. ●By toolmakers (moldmakers) in the process of manufacturing precision tooling. ●In metal engineering workshops, where a typical application is the centering of a lathe's workpiece in a four jaw chuck.

The DTI is used to indicate the run out (the misalignment between the work piece's axis of rotational symmetry and the axis of rotation of the spindle) of the work piece, with the ultimate aim of reducing it to a suitably small range using small chuck jaw adjustments. ●In areas other than manufacturing where accurate measurements need to be recorded, eg physics.
