Dial indicators, or dial gauges, are mechanical display instruments used to provide a readout of some small measurement not immediately discernable to the naked eye. Common dial indicators incorporate a dial display with arms and graduations on a circular scale, similar to a clock face. Internally, dial indicators incorporate a rack and pinion gear to read its probe position. In machining, dial indicators can be used to inspect variations in tolerance of machined parts, beam, ring, or rod deflection from its axis, calibrate a machine, manufacture precision tools, centering a workpiece in a lathe, inspecting for lateral run-out of a rotor, and other small measurements.
Mitutoyo America Corp.’s QM-Height Series measures height, height difference (step), inside/outside widths, inside/outside diameters, circle pitch, and free-form surface max/min heights to ±(2.4+2.1L/600) μm. Simple-to-use control panel enables most measurements to be made with one keystroke.
The multisensor MiSCAN Vision System is a coordinate measuring machine (CMM) with a microscopic-level scanning probe. The compact MiSTAR 555 is a space-saving in-line or near-line CNC CMM designed for high-speed, high-accuracy measurements with assurance from 10° C to 40° C.
Highly efficient and flexible, the Quick Vision Active CNC vision measuring system from Mitutoyo America uses advanced functionality to meet many contact and noncontact measuring needs in a wide field of view with interchangeable objective zoom lenses to meet the challenges of measuring small to large features.
