IMTS 2018: Quality Vision International will display its TurnCheck family of precision optical instruments for measuring shafts and other cylindrical parts.
Quality Vision International will display its TurnCheck family of precision optical instruments for measuring shafts and other cylindrical parts.Company-designed optics and are fully telecentric with each element designed to eliminate distortion. Supporting illumination consists of highly-collimated constant-wavelength light to eliminate a wrap-around effect found when lighting turned parts. The system is said to produce a crisp, uniformly illuminated and magnified image across the field of view with no edge effects or exclusion zones.
The system is intended to provide accurate measurements despite vibration and temperature variation often found in shop floor conditions. The system software automatically optimizes lighting, focus and image tools. Simple controls, easy loading and unloading, and intelligent software tools enabler fast setup time with no need for extensive operator training, the company says. Three model ranges are available to accommodate a parts as long as 1,200 mm.
Virtually every machine tool builder lists, as part of a machine's specification, accuracy and repeatability figures. What's generally not given is the method used to arrive at the figures. Though these methods are defined in linear positioning standards, not all builders use the same standards.
Measuring workpiece dimensions is relatively simple for machine operators but measuring workpiece geometry which involves more complex comparisons of part shape to an ideal shape--is now also practical on the shop floor. The gaging equipment for doing this is coming down in price while becoming easier to use.
Just because dial indicators have been around since the early 1900s, don't expect them to fade away with the last century. This tool's long-term popularity is well earned.
