EAS500 MicroTIR with 1 tower and 2 probes

Micro TIR + Engine Assembly Systems

Accuracy is the most important measurement metric, but efficiency and usability are almost just as critical. That means having a gage that is straightforward to use by operators of all skill levels, which is an absolute necessity. Our MicroTIR gages are quicker to set up, easier to use than a CMM, offer higher accuracy with more reliable results.

Designed specifically for checking total indicator readings (TIR) on OD, ID, and faces of cylindrical parts, the MicroTIR is focused on maximizing throughput. The friction-free ultra-precise air-bearing rotary table provides a stable, robust, and maintenance-free reference axis with certified system accuracy better than 5 millionths of an inch (5m” or 0.125mm)

The MicroTIR gage basic configuration includes a single-precision lever-type electronic indicator, probe fine adjust, gage stand, rotary air-bearing with tilt and center worktable mounted to an inspection grade granite surface plate, and MicroTIR touch screen display providing a turnkey system.

The user interface displays the results in a traditional analog-style needle and digital format. The maximum and minimum readings and TIR are captured removing potential operator error and user subjectivity. You can input part numbers and descriptions and your results can be saved or printed for customer verification or as a traveler for the part.

This versatile system allows you to measure and verify TIR on a wide array of parts ranging from gears, pistons, and jet-engine components for in-house inspection or incoming part inspections for vendor compliance.
