Coordinate boring machine, jig boring machine

Hauser OP3

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

Only available online until November 16, 2026!

The offer has been updated and now includes 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 significantly higher prices, up to three times my asking price. Please compare for yourself!

Due to the large number of inquiries: please only serious interested parties with a genuine intention to purchase, installment payments are not accepted! As long as the ad is online, the machine is still available. An inspection while the machine is powered on is expressly possible.
Only to be sold to appreciative users, such as watchmakers, precision engineering workshops, or testing workshops/prototype construction, not to profit-oriented dealers.

The coordinate drilling machine has been with its original 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 need for laborious manual cranking, as is the case with all other Hauser coordinate drilling machines.

The machine features thermal stabilization and expansion compensation. To this end, 2 heaters are provided, which are switched on separately before starting work and to maintain high accuracy and dimensional accuracy. This explains the factory-high positional accuracy of 0.002 mm.
It is worth mentioning 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 great 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 most likely no longer available in this form.

These machines are primarily used in the watch industry, gunsmithing, precision engineering, materials 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 wiring diagrams, etc. are available in their original form!

I prefer the machine to be collected by the buyer by means of a transport company or their own truck. Loading onto a truck is free of charge for the buyer. Shipping (direct transport without reloading) within the EU is still possib
