Hauser OP3

HENRI HAUSER OP3 High-precision drilling machine / coordinate drilling machine / jig boring machine (Made in Bienne/Biel, Switzerland). Excellent condition!

Machine available online for only 3 more weeks (until November 16, 2026).

The offer has been updated with even more accessories! Tool package with a value of approximately 12,500 EUR. A unique opportunity for connoisseurs of these machines at a special price. Hauser coordinate drilling machines in this condition are now mostly only available from specialized dealers in Switzerland, but at considerably higher prices, up to three times my asking price. Please compare for yourself!

Due to the many inquiries: please only contact us if you are a serious buyer with a genuine intention to purchase; installment payments will not be accepted! As long as the advertisement is online, the machine is still available. An inspection while the machine is powered on is expressly possible.

To be sold only to appreciative owners, such as watchmakers, precision engineering workshops, or testing workshops/prototype construction facilities, not to profit-oriented dealers.

The coordinate drilling machine was with its first owner for 41 years and features the rare option of a motorized table drive/rapid traverse in the X and Y axes, as well as potentiometers. The stepless feed in the X-axis also allows for light milling and surfacing operations. This eliminates the tedious manual cranking required in all other Hauser coordinate drilling machines.

The machine features thermal stabilization and expansion compensation. For this purpose, 2 heaters are provided, which are switched on separately before starting work to maintain high accuracy and dimensional precision. This explains the factory-specified high positioning accuracy of 0.002 mm.

It should be noted that the machine has two Heidenhain digital displays with a total of 4 glass scales with 1My resolution, also for the quill feed. This is a major advantage for precise drilling and surfacing in depth with Wohlhaupter, spindle tools, etc. With the options mentioned and in this first-class condition, it is very rare and highly unlikely to be available again in this form.

These machines are primarily used in the watch industry, gunsmithing, precision engineering, material testing, and the optical industry, where the highest precision is required. Also ideally suited for engine construction/overhaul, special machine construction, etc. All documents, manuals, electrical diagrams, etc. are available in their original form!
