Felder Format-4 spindle and motor spindle repair
Brochexpress is an independent workshop specializing in the repair, maintenance and diagnostics of Felder Group and Format-4 spindles and motor spindles — 4 and 5 axis CNC machining centres dedicated to wood and wood-based materials (joinery, interior fitting, furniture).
Felder Group and Format-4, CNC machining centres for wood
TLDR: Format-4 is the CNC and production machinery brand of the Austrian Felder Group. Its 4 and 5 axis machining centres ("profit" ranges) are fitted with high-speed motor spindles with HSK tool change.
Felder Group (Austria) sells its machines under several brands, including Format-4 for professional CNC machining equipment. Format-4 machining centres ("profit" series, for example H200, H350 or Profit3) are used by joiners, interior fitters and furniture makers for milling, drilling, sawing and machining complex shapes.
Many of these machines circulate on the second-hand market: a fleet in continuous operation, and therefore recurring needs for maintenance and overhaul of Format-4 spindles and their motor spindles.
High-speed 5 axis Format-4 motor spindles
TLDR: On the 5 axis machines observed, the Format-4 motor spindle is a gimbal unit (A and C axes), liquid cooled, with ceramic bearings and an HSK F63 interface.
As an example, a listing for a Format-4 Profit H350 centre (2018) describes a 12 kW (S6) 5 axis motor spindle, maximum speed 24,000 rpm, range 1,000 to 24,000 rpm, with full power available from around 12,000 rpm. This configuration is described with an HSK F63 interface, liquid cooling of the spindle, air-cooled ceramic bearings, and optional additional clamping of the A and C axes.
The maker of the motor spindle is not stated in that listing. Exact specifications vary with the model and year of the machine.
