GOEKELER Messtechnik GmbH is a medium-sized, family-owned company based in Lenningen at the foot of the Swabian Alb near Stuttgart. Since 1984, the company has manufactured precision styli (touch probes) and accessories for coordinate measuring machines (CMM), surface, roughness and contour measuring machines (FOK), production machines and computed tomography systems. The product range includes straight styli, star styli and disc styli with probing balls made of ruby, silicon nitride, ceramic, carbide and diamond-coated balls, as well as shafts made of carbide, ceramic and carbon fiber. A special feature is vacuum brazing technology (Vacuum Styli Technology), in which the ball-shaft joint is produced automatically at around 800 °C in a vacuum brazing process. In addition to series production and semi-automated custom manufacturing from lot size 1 to 1000, the company offers DAkkS-calibrated CT-Check test artifacts, a repair service and a 3D configurator for special styli. Deliveries are made worldwide to measuring machine manufacturers and their end users.
