The Microgage bore alignment kit for industrial applications is designed for aligning extrusion presses, rams, precision screws, lathes and turning centers, propeller shafts and stern tubes, bar feeders and many other applications.
This system consists of a cylindrical laser available in either a 2.250" or 1.000" diameter that is held in the bore, toolholder, chuck or shaft mount. The laser reference beam is projected to a digital receiver that is held in a mount with a similar precision bore diameter. This mount is reversible so that the receiver can catch the laser beam coming either through the bore tube or from the outside and measurement readings are then transmitted to a hand-held display. Readings as small as 0.0001" (0.003 mm) define the bore or shaft's alignment and guide the user to what changes are needed for optimal performance. Measurements can be made over a range of 80 ft, and simple fixtures expand the options for aligning a variety of machines. A computer interface can store readings and connect the system to common programs and spreadsheets.
