Machines voor ultra-precisie bewerkingen

Ultra-precision is defined in terms of dimensional tolerances, accuracy of form and surface roughness. These requirements can only be met by the use of dedicated machines, such as the lathes built by the Dutch specialist machine manuf acturer ?Hem b r u g B.V.?. The many factors that have an influence on the cutting process are briefly discussed. The special engineering solutions, to eliminate intolerable eff ects and necessary to achieve the required precision results, are described. Finally examples of machines as built by the Dutch manufacturer are illustrated and their specification briefly mentioned.
