Micrometer

July 31, 2008


The QuantuMike line of micrometers provides accuracy at ±1 micrometer throughout its measuring range and also is dust and water resistant-rated IP65. A coarse thread feeds the spindle at 2 millimeters per thimble-revolution instead of the standard 0.5 millimeter. The increase in thread lead is made possible by high-precision thread cutting and testing techniques. Trials on typical workpieces show that compared to conventional micrometers the gage’s spindle positioning time is reduced by about 60% while overall measurement time is decreased by as much as 35%. In tests where a conventional micrometer took 53 seconds to position and measure six diameters on a single, stepped workpiece, the gage performed the same measurements in 22 seconds.
