Tactile measuring is mostly carried out in CNC controlled tool grinding machines or cheap setting aids. Presetters and measuring machines with dial gauge holders have been no more up-to-date for a long time already, as measuring in a tactile way is too unprecise, too circumstantial and most of all for modern cutting materials too dangerous. Even the least touch pressure always carries the danger of damaging the tool cutting edge (CBN/PKD), what would incapacitate the expensive cutting materials, thus tools at the end. Furthermore, measuring in a tactile way has the disadvantage of being able to take up only single measuring points. A for processing relevant tool cutting edge consists as is well known of sometimes thousands of measuring points for being able to check parameters as cutting edge angle, concentricity, radius contour and so on. Such measuring and checking operations are realized with ZOLLER presetting and measuring machines by image processing technology, µ-precise, independent of the operator and first of all without any touch. Even measuring of threedimensional objects, such as chip space (front rake angle, flute depth, protective chamfer), cutting edges on the circumference (chamfer width, clearance angle 1 and 2, drop…) or frontal area (cutting edge rounding, chisel angle, offset,...) is managed with ZOLLER image processing technology by CCD camera and special measuring methods. These methods of ZOLLER are clearly faster, as they deliver a big number of measuring points at the same time, and are more precise, as the calculation factors in all of the area models and they work without touching.
