Marposs, announced in a press release dated June 25, 2020 its new Aeroel Grindline Laser System designed for measuring the outer diameter and taper of parts finished by through-feed or plunge centerless grinders. These include parts such as electric motor shafts, shock absorber rods, pins, steering racks and more. Grindline enables 100% inspection, detecting out-of-tolerance parts to reduce scrap and labor costs while improving quality, according to Marposs.
The Grindline+.X System relies on an Xactum Laser Gauge 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 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 data processing software, featuring automatic shape recognition of ground parts, can gauge 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, according to the company.
Grindline systems feature Aeorel’s NO-VAR Technology, which prevents measuring drift due to changing room temperature. Standard systems come with an Xactum Laser Gauge, CE-200 Operator’s Interface Panel with LCD display, 19” Rack mount version, pre-installed Grindline+.X software, and a 5m long connecting cable.
Depending on the system, measuring fields are available up to 40mm or 80mm, measuring diameters from 0.06 to 38mm or 0.75 to 78mm, with a repeatability of ± 0.1mm or ± 0.3 mm.
