One measure of a tool’s usefulness is how many different jobs it can do. Another is its accuracy.
Mitutoyo’s new profilometer, the SurfaceMeasure 1008S, delivers on both counts. The sensor is guaranteed for an accuracy of 20 microns along with a vertical-axis repeatability of 0.5 micron, and it can handle inspections from panel gaps on automobiles to tire shapes, connector pins and food, the company says.
The tool is the most accurate in its class, which appeals even to customers performing jobs that don’t require that degree of precision, says Michael Browner, product manager for sensors at Mitutoyo America.
Generally, “having more accurate sensors and tools in a new application makes CNC machinists more comfortable with the unknowns for which they can’t make adjustments until the process is up and running,” he says.
The 1008S, which Mitutoyo describes as a two- or three-dimensional non-contact laser line sensor, is the first in a series. It can be attached to stationary as well as flexible inspection points, including the arms of robotic equipment, for real-time quality control. The scanner can also be used alone or in an array.
Performing inline non-contact scans on each item going through a production line lets machinists identify right away which ones aren’t meeting specifications, Browner says.
The quick turnaround enables them to avoid the quality-control gaps that occur with periodic inspections of samples by hand, sometimes forcing the scrappage of large numbers of workpieces—an expensive problem, especially for small shops that run on tight margins.
Scrapping costs can be even higher for firms working with exotic metals and alloys required in the aerospace industry as well as the developing electric vehicle market.
