Quality control in the technical dental.

AmannGirrbach AG company employs measuring devices by coordinates of Carl Zeiss

Madrid, December 2009.- manual work characterized the dental laboratories. Materials of high quality and precision to detail contribute to improving the health and well-being of patients. Most modern production processes ensure a high quality. To ensure that quality, AmannGirrbach offers 500 articles for the dental industry, from articulators or simulators of chewing, to wear material.

A dental prosthesis in high precision, which can reduce considerably the finishes and final reviews, is more important than ever in the area of dental technology. For the production of models, it is essential to count on devices manufactured with high accuracy to ensure an optimal dental prosthesis. It is therefore necessary to have precise measurement equipment to verify the quality of the manufactured parts. To offer customers high quality products, AmannGirrbach has implemented the combination of a machine for measuring coordinates with ZEISS CONTURA ® G2 touch technology with the team multisensórico O-INSPECT of óptico-táctil measurement.

Optimization of the quality assurance

Changes in the product portfolio, which increasingly require tighter tolerances and provide a greater number of surfaces of free-form, require new paths in quality assurance technology. AmannGirrbach immediately recognized that the quality was more than an obligation. The implementation of a CWC (Computer Aided Quality – computer-aided quality) system required obtain repeatable processes, resulting in extensive control over the quality of the produced parts. Mario Fröhle, responsible for quality of AmannGirrbach, emphasizes: ’quality control shortens and optimize the production process. But it must not be the only role of quality control employees. The easy handling of the ZEISS coordinate measurement teams is a key element. «Inspection has become so part of the day to day.»
machines of measurement for coordinates on the quality control have significantly shortened the verification processes and reduce the number of rejections. Pieces whose verification is less than ten minutes, can now check in three minutes by CNC processes. But shorten measurement times was not the only deciding factor, but rather also the growing number of shape and position tolerances required flexible methods in quality control. Here is where more patents are the advantages of the Carl Zeiss scanning technology. With this technology not only longitudinal tolerances can be verified, but also those of form and position. small quantities and different pieces require frequent changes in the configuration of the machines production fair here is important to have a system of measurement for coordinates and a consistent software correction values to provide to the operator of fast and reliable way.

Optical and tactile measurement with CALYPSO

Measuring software quality both in the CONTURA G2 MMC and MMC óptico-táctil O-INSPECT can check CALYPSO ®. In this way, the user works always under the same user interface, regardless of the metering equipment with which to verify the piece.
