• Ultra-high accuracy contour tracing
• Ultra-high accuracy roundness, form, and GD&T testing
• Cylindricity testing & measuring
• Internal thread forms
• Knife-edge sharpness
• Involute forms & serrations
• Ball screw Gothic arch forms

While the typical CMM is an extremely versatile instrument, many precision measurements simply cannot be properly made due to size, tight-tolerance requirements and the like. For such situations, IIA utilizes ultra-high accuracy purpose-specific measurement devices including a contour tracing profile scanner and a form tester that can measure roundness, cylindricity, flatness, run-out, perpendicularity and many other GD&T (Geometric Dimensioning & Tolerancing) requirements.

Both instruments are continuous contact, bridging the best of the analog and digital worlds. These instruments are also fully automated and programmable.
