Mandelli spindle and motor spindle repair
Brochexpress is an independent workshop specializing in the repair, maintenance and diagnostics of Mandelli spindles and motor spindles — an Italian manufacturer renowned for its large-capacity horizontal machining centres, notably for aerospace and the machining of hard materials such as titanium.
Mandelli, an Italian benchmark for large-capacity machining
TLDR: Mandelli Sistemi (Piacenza, Italy, founded in 1932, Riello group) designs large-capacity horizontal machining centres, notably the Spark range, renowned for their fixed-table architecture and their solutions dedicated to machining hard materials for aerospace and energy.
Founded in 1932 by Renato Mandelli and based in Piacenza, the manufacturer has specialized in large-capacity horizontal machining centres intended for bulky and complex parts: aerospace structures, pump and turbine bodies, electric motor flanges, clutch bells. The Spark range, with its fixed-table architecture, stands out for its high-torque pivoting spindle heads, fitted with backlash take-up and machining vibration damping systems, as well as guidance solutions combining roller pads and Turcite prismatic ways for vibration control. Some machines, such as the Spark 1300 Titanium, integrate specific spindle drives with a coaxial gearbox to deliver high torque (up to around 2,500 Nm) at low speed for titanium roughing, while retaining high rotation speeds for finishing.
A range of spindle heads suited to machining massive parts and hard materials
TLDR: Mandelli spindle heads cover a wide speed range (5,000 to 30,000 rpm depending on configuration) with high torque and power values, including multifunction pivoting heads (milling/turning) for machining large parts.
The motor spindles equipping Mandelli machining centres cover a wide range of rotation speeds, from 5,000 to 30,000 rpm depending on the configuration, with high torque and power values suited to both heavy machining and high-speed finishing. The horizontal/vertical pivoting heads, found in particular on multifunction machines capable of combining milling and turning, integrate backlash take-up devices specific to Mandelli patents. On configurations dedicated to machining hard materials (titanium, superalloys), some spindles are combined with two-range gearboxes to offer both high torque in roughing and high rotation speed in finishing.

Frequently asked questions
Do you repair Mandelli multifunction milling/turning pivoting spindle heads?
Yes, we work on horizontal/vertical pivoting spindle heads, including multifunction configurations fitted with turning tool holders.
Do you work on spindles dedicated to machining hard materials (titanium, superalloys)?
Yes, we diagnose and repair the spindles and associated gearboxes, taking into account the specific high-torque constraints of these applications.
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 directly on site for large spindle heads?
Yes, our team travels to diagnose and, where possible, work directly on site to avoid the complete removal of bulky and heavy heads.
Do you offer a preventive maintenance contract for a fleet of Mandelli machines?
Yes, we set up preventive maintenance programmes tailored to your production rate and the criticality of your machines, particularly for aerospace and energy workshops.
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 the entire Mandelli range — spindle heads and motor spindles for large-capacity machining centres — with the responsiveness and rigour demanded by the most exacting industrial environments: aerospace, energy and heavy general engineering.
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.
