Test Dial Indicators

The dial indicators (or comparative gauges) are high-precision measuring instruments used to check the deviations of a surface from a reference point. They are essential for machine tool setup and component quality control, as they can detect differences on the order of 0,01 mm or even 0,001 mm.

• Types:Face (Plunger Type): They have a spindle that moves linearly up and down. Ideal for measuring flatness and perpendicularity.Test indicators (Lever Type): They have a rotating stylus (lever). They are extremely versatile for measurements in hard-to-reach areas or for checking radial deviation (run-out) on lathes.
• Applications: * Alignment of parts in the lathe chuck.Checking parallelism on milling machine tables.Measuring wear on brake discs or engine shafts.
• Use with Magnetic Base: For the indicator to operate, it must be mounted on a stable magnetic base with articulated arms, so that it remains stationary during the measurement.
