Laser system measures ground parts diameters

Auburn Hills, Michigan – Marposs, a world leader in measurement, inspection, and test technologies, has announced its Aeroel Grindline Laser System designed specifically for measuring the outer diameter and taper of parts finished by through-feed or plunge centerless grinders such as electric motor shafts, shock absorber rods, pins, steering racks, and more. Highly accurate and extremely flexible, Grindline enables 100% inspection, detecting out-of-tolerance parts to reduce scrap and labor costs while improving quality.

The Grindline+.X System relies on an Xactum Laser Gage installed at the output of the grinder for measuring parts after the machining process without the need for stopping production. The ground parts, after being cleaned, pass through the laser beam where hundreds of measurements are recorded along the axis of the piece and processed by the software. The measured diameters are displayed and compared with the pre-set nominal value: if the process drifts beyond the pre-set control limits, the Grindline software automatically compensates for wear of the grinding wheel to keep the product within the desired tolerance limits. The collected data can be processed in real time or downloaded to a remote computer.

The exclusive data processing software, featuring automatic shape recognition of ground parts, can gage up to 10 different diameters on components while ignoring all shape irregularities that could compromise measurement results. Chamfers, grooves, threads, through holes, or drops of emulsion on the work piece are unable to deceive the system.

Grindline systems feature Aeorel’s exclusive NO-VAR Technology, which prevents measuring drift due to changing room temperature. Standard systems come with an Xactum Laser Gage, CE-200 Operator’s Interface Panel with LCD display, 19" rack mount version, pre-installed Grindline+.X software, and a 5m connecting cable. Depending on the system, measuring fields are available up to 40mm or 80mm, measuring diameters from 0.06mm to 38mm or 0.75mm to 78mm, with a repeatability of ±0.1mm or ±0.3 mm.
