Specializing in Gear Metrology & Analyzing Systems

MicroGear delivers industry-leading gear inspection, metrology calibration, and custom electronic retrofit solutions for gear manufacturers, aerospace laboratories, and precision machining facilities worldwide. Retrofit your existing gear testing machinery with our flagship gear analyzing system, MicroCheck™ — an uncompromisingly versatile, computerized testing package engineered to run the entire measurement process automatically.

Test results with comprehensive composite inspection charts are displayed in real-time on your monitor, with automated pass/fail tolerance evaluation against AGMA, DIN, and ISO standards. The checking procedure is fast, automatic, and delivers 100% precision inspection with micro-inch resolution.

The Anatomy of Accurate Gear Testing

Total Composite Error (TCE / Fi”): Total variation in working center distance over one complete 360° revolution of the test gear.
Tooth-to-Tooth Composite Error (TTCE / fi”): Maximum center distance variation across any single tooth engagement angle (360/N).
Tooth Thickness & Pitch Fluctuation: Immediate micro-inch detection of tool wear, poorly deburred blanks, and spacing irregularities.
Flank & Profile Form Error: Real-time graphical visualization of axial runout, mounting axis tilt, and base circle deviation.
Turnkey Machine Retrofits: Direct electronic and mechanical integration for ITW, Schoppe & Faeser, Vari-Roll, Fellows, Parkson, and custom testers.
