Coordinate measuring machine in portal design using touching tips has bearings with spacing from each other of same or smaller than half of process path of sleeve

摘要

The machine includes bearings (9,10) with a spacing from each other being the same or smaller than half of the process path of the sleeve (2). An optimal gap results from a touching action of touching tip (4) on a measurement object (5) in variable gap of a guide bearing (9). It takes into consideration the rigidity of the guide bearings (9,10), due to the deformation of the touching tip (4) due to a minimal contact force caused by the measurement object (5) to provide optimal the measuring accuracy.
