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 11/16/2026).

The offer has been updated with even more accessories! Tool package worth 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 prices yourself.

Due to the many inquiries: please only contact me 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 with the machine powered on is expressly possible.

To be sold only to a good and appreciative owner, preferably to watchmakers/manufacturers, not to profit-oriented dealers.

The coordinate drilling machine was 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 and a potentiometer. The stepless feed in the X-axis also allows for light milling and surfacing operations. This eliminates the need for tedious manual cranking, as with all other Hauser coordinate drilling machines.

Furthermore, it has the rare thermal stabilization and expansion compensation feature. Two heaters are provided for this purpose, which can and must be switched on separately before starting work to maintain high accuracy and dimensional precision. This explains the factory-high positioning accuracy of 0.002 mm with a resolution of 0.00.

It is worth noting 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 mentioned options and in this first-class condition, it is very rare and highly likely not available elsewhere.

These machines are mainly 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 the original.

Dimensions of the machine: Length = 1400 mm, Width = 1250 mm, Height = 1750 mm, Machine weight approx. 1500 kg.

Payment for the machine is made, as is customary for used machines, in full and net before loading, no partial or installment payments!

I prefer the machine to be picked up by the buyer via a freight forwarder or in their own truck. Loading onto a truck is free of charge for the buyer. Shipping (direct transport without transshipment) within the EU is still possible, depending on the country.
