Improve quality and lower costs with roundness verification.

Verification of geometrical tolerances, including roundness, is a must in today's quality-conscious environment.Roundness measuring machines with the ability to perform product verification in conformity with ISO, JIS and other standards are indispensable to any quality control system that aspires to implementing high-grade quality assurance. Heightened awareness of production quality and higher quality goods will help enhance your corporate image with the buying public.

Roundness verification attempted using basic measuring tools involves the following drawbacks:

Once roundness measuring machines are introduced into quality control:

Simple, beginner-friendly operation

High accuracy even though it is a low-end machine

Large LCD panel displays measurement results and recorded profiles in an easy-to-view fashion

The built-in high-grade thermal printer prints out measurement results and recorded profiles on demand

Compact design means small installation space

Options that further enhance usability

Four easy steps to measurement

Clamp the workpiece to the jig.

Bring the detector into contact with the workpiece.

Press the [CONDITION (setup recall)] button, as needed.

Press the [START] button.
