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.
• Measurement is not conducted by a radiusmethod conforming to the standards, forwhich a reference axis is necessary.
• Measurement verification that meets theaccuracy required by the drawings cannot beperformed.
• Recorded profiles cannot be obtained.
Three-point method using an indicator and V-block has better resolution but is not sensitive to common lobing conditions.
• Reduction
