Carl Zeiss IMT with his technology MASS is one of the mates from does more than 10 years of the company Grass. This company, founded in 1947, is one of the first manufacturers of ironingwork for furniture and machines of processing. The differential value of Grass are the extractor systems equipment equipment of modern drawers, which in addition to opening and close, do it silently thanks to the inventive system of amortiguación ‘Soft Close'. Even, some of these pieces of furniture no longer have fencers, but they open and close automatically of tactile way. Besides, some work electronically and can program for distinct tasks, as for example that it open only a drawer, so that the drawers close to different order or so that a determinate drawer of hygiene keep closed. This technology that allows to create intelligent drawers, does that to his time the manufacture of the systems of guides are more difficult. Thus, it demands carry a strict and effective control of quality. “If the dimensions of our components do not fit with accuracy, the drawer will not displace slightly by the rail”, explains Ehgartner, operario of measurement in Grass, “the customer notices it quickly”. From the implementation of the Or-Inspect of Carl Zeiss, Grass has reduced to the half the work that requires the control of quality. “Before, the manufacturing of the reports of verification of the first samples required of long”, stands out Mark Ehgartner. “In place of two weeks, at present need so only five days”. For this reason, Grass purchased, in the year 2000, the machine of measurement by coordinates Prismo Vast of Carl Zeiss, that offered an excellent accuracy and precision. It used mainly for the control of quality of the first samples of the component.
Previously, Grass used five distinct devices for his controls of quality, in which the employees needed some two weeks to elaborate a report of verification. All this work came to simplify it the technology MASS of Carl Zeiss with the machine of optical measurement-tactile Or-Inspect. “The advantage is that the user can change between tactile and optical measurement”, stands out Mario Sheiber, regional executive director of the subsidiary of Carl Zeiss IMT in the west of Austria. Another of the advantages that offers is, beyond all doubt, his software Calypso. “We wanted to avoid that our employees had to learn the operation of a new software”, stands out Ehgartner. This software retains automatically all the measures and with so alone presses a button, the employee can elaborate a statistics that gives him all the necessary information of a glimpse, in place to have to annotate manually, as in the past it realised in each one of the 420 measures of a table. The Or-Inspect installed in Grass verifies thousands of components to the year.
