Step-Tec spindle and motorized spindle repair
Brochexpress is an independent workshop specializing in the repair, maintenance and diagnostics of Step-Tec spindles, motorized spindles and milling heads.
Step-Tec spindles and motorized spindles equip many machining centers and production milling machines operating under the highest precision demands, notably in aerospace, mould and die, and precision subcontracting. Drawing on our technical expertise, we support manufacturers — across France and Europe — in restoring their equipment and optimizing uptime. A properly maintained spindle is the guarantee of accurate, repeatable and productive machining.
Step-Tec — manufacturer of spindles and motorized spindles
Step-Tec AG is a Swiss manufacturer recognized for its high-performance motorized spindles, fitted in particular on GF Machining Solutions machines (Mikron, AgieCharmilles). Its solutions are found on many demanding 3- to 5-axis machining centers, in sectors such as aerospace, mould and die, medical and precision subcontracting.
Maintaining these assemblies requires in-depth knowledge of their architecture and appropriate inspection equipment. That is precisely what Brochexpress has provided for over 30 years, from our sites in Beaurepaire (France) and Lussery-Villars (Switzerland).
