Esco spindle and motor spindle repair
Brochexpress is an independent workshop specialising in the repair, maintenance and diagnostics of Esco spindles, motor spindles and rotating heads — the historic Swiss manufacturer of turning from coil or bar stock, and the originator of the unique Escomatic® principle.
Esco, Swiss world specialist in turning from coil stock
TLDR: Esco (Les Geneveys-sur-Coffrane, Switzerland) is the historic manufacturer behind the Escomatic® principle, a unique approach to turning in which the material, fed from coil or bar, remains stationary while the tools, carried by a rotating turning head, revolve around it to remove chips.
Unlike conventional lathes, Esco's Escomatic lathes rely on a unique principle: the material, fed as coil or bar, has no rotational movement; it is the tools, supported by a rotating turning head, that revolve at minimal distance around the material. This high-performance principle delivers unmatched productivity at low cost, with cycle times reaching up to 100 parts per minute on the most productive configurations. The range covers several machine generations (D2, D5, NM6, NM8 Flexi), with accuracy down to ±3 to 4 µm, meeting the requirements of varied industries: watchmaking, medical, connectors and automotive.
A range of rotating tool-holder heads and second-operation spindles
TLDR: Escomatic machines use a rotating head able to carry several tool sets (up to 2 x 2 CNC-driven tools) turning at up to 8,000 rpm, combined with independent cross slides and, on the most advanced configurations, a C-axis sub-spindle for second-operation work.
On the Escomatic NM8 Flexi, the material is straightened up to 8 mm in diameter, then fed into the guide bush at the centre of the rotating head, on which two sets of two CNC-driven tools work in parallel at up to 8,000 rpm. Facing this main spindle, two independent cross slides allow simultaneous machining of two parts. On the most complete units (DUAL device), one station groups up to six tool-holder spindles and, optionally, four additional turning tools, with a three-axis CNC slide carrying a C-axis sub-spindle that picks up finished parts at cut-off to complete their machining in a second station.
Esco spindles covered (non-exhaustive list)
- Escomatic rotating tool-holder heads, up to 8,000 rpm
- Second-operation spindles and C-axis sub-spindles, DUAL device
- Multiple tool-holder spindles (up to 6 spindles per station)
- Spindles of independent cross slides for simultaneous machining
- Escomatic automatic lathe spindles, all generations (D2, D5, NM6, NM8)
Interfaces and specifications
The Esco rotating heads and spindles we repair can reach 8,000 rpm, with machining accuracy typically of ±3 to 4 µm — specifications to be confirmed on quotation according to the exact reference of your machine.

Frequently asked questions
Do you repair the rotating tool-holder heads of the Escomatic principle?
Yes, we work on these heads, taking into account their mechanism revolving around stationary material.
Do you work on the C-axis sub-spindles of the DUAL device?
Yes, we diagnose and repair these spindles, dedicated to picking up parts after cut-off.
What is the average lead time for a full overhaul?
Allow around 20 working days in the workshop, depending on the condition of the spindle and the availability of parts (bearings, seals, specific components).
Do you work on historic Escomatic lathes (D2, D5) still in production?
Yes, we diagnose and repair the spindles whatever the generation of the machine.
Do you offer a preventive maintenance contract for a fleet of Esco machines?
Yes, we draw up preventive maintenance programmes tailored to your production pace, particularly relevant for very high-output lines.
A reliable partner for your industrial performance
Whether it is an emergency on-site intervention, a full workshop overhaul or a preventive maintenance programme, Brochexpress brings its expertise to your production. As an independent workshop, we work across all Esco (Escomatic) spindles and motor spindles — rotating heads and spindles of automatic lathes running from coil or bar stock — with the responsiveness and rigour demanded by the most exacting industrial environments: watchmaking, medical, connectors and automotive.
Our teams are at your disposal from our sites in Beaurepaire (France) and Lussery-Villars (Switzerland) for a study of your needs, a diagnosis or a personalised quotation.
