Comau spindle and motor spindle repair
Brochexpress is an independent workshop specialising in the repair, maintenance and diagnostics of Comau spindles and motor spindles — the Italian manufacturer from Turin founded in 1970, a world leader in industrial automation and machining centres for the automotive industry, historically linked to the Fiat group.
Comau, Italian leader in automation and automotive machining since 1970
TLDR: Comau (COnsorzio MAcchine Utensili, Turin, Italy, founded in 1970-1973 by bringing together several machine tool manufacturers from the automotive sector working for Fiat) is today a world benchmark in automated machining centres, industrial robotics and production systems for the automotive industry.
Born in 1970 from the grouping of a number of machine tool manufacturers in the automotive sector working for the Fiat group, Comau developed over the decades by integrating several manufacturers from Turin and abroad (M.S.T., Morando, I.M.P., Colubra Lamsat, Berto Lamet, TEA, UTS, and the Spanish company Mecaner) to become a world benchmark in automatic welding, painting and machining centre systems. The Powertrain Machining & Assembly business unit develops new-generation horizontal machining centres, such as the SmartDriveComau 800L, designed for high-volume production of automotive components, with a modular architecture (X and Y axes under the spindle, Z axis under the part) and close integration with automated loading and unloading systems, delivering a 5% gain in overall line efficiency (OEE) compared with conventional systems.
A range of spindles and motor spindles with direct drive by linear motors
TLDR: Comau horizontal machining centres use motor spindles with an HSK 63 interface, reaching 16,000 rpm, with translation axes driven directly by linear motors and rotary tables with direct torque motor drive, for speed and long-term stable accuracy.
Comau horizontal machining centres are fitted with linear motors and motor spindles delivering speed, dynamic performance and long-term stable accuracy, with reduced maintenance requirements. On the 1GXL model, dedicated to cylinder head machining, the spindle runs at 16,000 rpm with an HSK 63 tool taper, combined with a 23-tool magazine and a two-position pallet changer allowing loading and unloading in hidden cycle time. The translation axes are driven directly by linear motors, while the rotary tables, available in 4 or 5-axis versions, also use direct torque motor drive — an architecture that removes intermediate mechanical elements for better dynamics and increased stability over time. On centres dedicated to crankshaft machining (SmartRevComau range), a compact swivelling spindle equips the vertical configurations with automated loading.

Frequently asked questions
Do you repair the HSK 63 motor spindles of SmartDrive horizontal machining centres?
Yes, we work on these spindles, whatever the rotation speed configured.
Do you work on the swivelling spindles of crankshaft machining centres, SmartRevComau range?
Yes, we diagnose and repair these spindles, whatever the vertical or horizontal configuration.
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 older Comau machining centres still in automotive production?
Yes, we diagnose and repair the spindles whatever the age of the machine.
Do you offer a preventive maintenance contract for a fleet of Comau machines?
Yes, we set up preventive maintenance programmes tailored to your production rate, particularly relevant for the automotive industry.
