(Bienne/Biel, Switzerland) This quality will never be produced again! Coordinate drilling machine/precision drilling machine with tool package in excellent, exceptional condition, second-hand (owned for 41 years). The coordinate drilling machine features the rare option of motorized table drive in the X and Y axes, along with potentiometers. This eliminates the tedious process of manually positioning each coordinate over longer distances using hand cranks. Furthermore, it has the rare thermal stabilization and expansion compensation system. This is achieved through 2 heaters that can and must be switched on separately before starting work and to maintain high accuracy and dimensional precision. This explains the factory-set high positioning accuracy of 0.002 mm with a resolution of 0.001 mm. What is truly unique is that the Hauser has two Heidenhain digital displays with a total of 4 glass scales with 1My resolution, including for the quill feed. This is a major advantage for precise drilling and surfacing in depth with Wohlhaupter, spindle tools, etc. With the aforementioned options and in this first-class condition, it is very rare and most likely no longer available. Those familiar with these machines, which are primarily used in the watch industry, gunsmithing/defense industry, precision engineering, material testing, and the optical industry, understand the value of these masterpieces of mechanical engineering. It is also ideally suited for engine construction/overhaul, technical universities and training, materials technology, special machine construction, etc. All documents, manuals, electrical wiring diagrams, etc. are, of course, available in their original form!
