Lagun spindle and motor spindle repair
Brochexpress is an independent workshop specialising in the repair, maintenance and diagnostics of Lagun spindles and motor spindles — a historic Spanish manufacturer of conventional milling machines and machining centres, with spindles ranging from the traditional SA40 taper to modern 15,000 rpm motor spindles.
Lagun, a Spanish manufacturer of conventional milling machines turned machining centre specialist
TLDR: Lagun built a solid reputation in Spain and across Europe with its conventional turret milling machines (FT, FTV series), widely used in general engineering workshops, before evolving its range towards modern 3- and 5-axis vertical machining centres, with the manufacturer claiming constant, day-to-day technical development.
Over the decades, Lagun built a solid reputation in Spain and across Europe thanks to its conventional turret milling machines, such as the FT and FTV series, widely used in general engineering workshops and still numerous in service today. These historic machines, robust and simple to maintain, earned the manufacturer a reputation well deserved by its products, praised by long-standing users on specialist technical forums. Lagun has evolved its range towards modern vertical machining centres, now covering travels from 850 to 1,620 mm (L850 to L1600 series), as well as a 5-axis range (evZ630 model) designed on an innovative architecture offering a high degree of customisation and automation — the manufacturer claiming daily work on the constant evolution of its 3- and 5-axis machining centres.
A range of spindles from the conventional SA40 taper to the 15,000 rpm motor spindle
TLDR: Lagun conventional milling machines feature an ISO/SA 40 or 50 taper spindle, with speed ranges from 50 to 4,200 rpm, while the modern L series machining centres offer BT 40 taper spindles reaching up to 8,000 rpm as standard, with a motor spindle option raising the speed to 12,000-15,000 rpm.
On Lagun conventional milling machines, such as the FTV series, the spindle is on an ISO/SA 40 taper (DIN 2080 standard), with a speed range of 50 to 4,200 rpm depending on the electrical frequency, a 127 mm quill travel and a chromed quill diameter of 85.70 mm, for a head tiltable ±90° laterally and ±45° front to back. On the FBF series horizontal milling machines, the ISO 50 taper spindle covers a range of 50 to 3,000 rpm. On the modern L series vertical machining centres (L850 to L1600), the BT 40 taper spindle reaches 8,000 rpm in standard configuration (belt-pulley), for a power of 7.5 to 15.5 kW depending on the model; as an option, a motor spindle raises the speed to 12,000-15,000 rpm, with through-tool coolant (20 to 40 bar) and an arm-type tool changer able to hold up to 30 stations.
