Description

5-axis moving bridge CNC milling machine

The FCN is a moving bridge CNC machining centre developed by BERMAQ to meet the needs of the most demanding customers. It is a versatile, modular and robust machine, configurable with 3 to 5 controlled axes, providing solutions for the mould and model sector in wood, aluminium and resin.

Its moving bridge structure, high dynamic performance and power make it the solution for parts that demand high quality and precision in the finish. Companies in the automotive, marine, railway and aerospace industries, as well as manufacturers of aluminium moulds and models, take advantage of its large-format capacity.

Applications of the FCN milling machine

From aluminium moulds to solid wood furniture in a single centre

The modularity of the FCN lets it move from a large model to a series of technical parts or a board nesting job without changing machines. These are its most common applications:

Moulds and models: small aluminium and resin moulds and models for automotive, aeronautics and railway.
Furniture and joinery: solid wood, kitchen and bathroom furniture, doors, windows and staircases.
Large-format panels: machining for manufacturers of large panels and trimming of plasterboard sheets.
Nesting: nesting of parts on metal sheets and chipboard panels to make the most of the material.
Profiles and technical parts: machining of aluminium profiles in general and trimming of technical parts with a precise finish.

How the FCN milling machine works

3 to 5 controlled axes to suit the process

The FCN is set up with the number of axes each application requires, from 3 to 5 controlled axes. In its 5-axis configuration, the A axis rotates ±90° and the C axis ±200°, both at 135°/s, to machine three-dimensional surfaces and inclined faces in a single set-up. It also accepts a C-axis adaptation for aggregates.

Spindles of up to 20 kW with ISO or HSK taper

The air- or liquid-cooled milling motor delivers up to 20 kW, with a nominal speed of 12,000 rpm and a maximum of 24,000 rpm. The 18-position turret tool changer chains roughing, finishing and drilling without stopping production.

60 m/min dynamics on the X and Y axes

With feed rates of 60 m/min in X and Y and 25 m/min in Z, the FCN cuts idle travel time even on the longest machines. A precision of ±0.053 mm and a repeatability of ±0.015 mm ensure that every part in the batch is identical to the previous one.

Phenolic resin table with one or two working areas

The phenolic resin vacuum table, with a 140 m³/h or 250 m³/h pump, can be divided into one or two working areas to organise part loading by zones. The numerical control can be SIEMENS, HEIDENHAIN or FANUC.

Architecture and manufacture of the FCN milling machine

Robust moving bridge for large parts

The FCN moving bridge offers a working width of up to 3,800 mm and a Z height of 1,250 mm, and the range is completed by an extra-long XL version and XXL configurations for large parts. Its robustness guarantees continuous performance in demanding production environments.

Design validated by CAE analysis and kinematic calibration

BERMAQ’s engineering department designs the FCN with parametric 3D software and validates it through finite element analysis against vibration, thermal conduction and overload. Kinematic calibration keeps the tool tip static while the axes move, so parts can be machined accurately from any angle.

Adapt the FCN to your production

Modular configurations of the FCN range

Custom spindle: different power ratings up to 20 kW, air or liquid cooling and ISO or HSK taper.
Table and vacuum: one or two working areas and a 140 m³/h or 250 m³/h pump depending on the part format.
C axis for aggregates: extends the operations possible on the part without changing machines.
Special versions: the FCN-P XXL, with two independent bridges, machines parts up to 12 metres long or works in four simultaneous zones.

Materials compatible with the FCN milling machine

True versatility across light metals, wood and composites

The FCN is designed for non-ferrous materials and performs just as reliably in a mould shop as in a woodworking plant:

Aluminium: small moulds, profiles and sheet nesting with high-quality finishes.
Composites: trimming and machining of technical parts for automotive, aeronautics and railway.
Solid wood and panels: furniture, doors, windows, staircases and chipboard nesting.
Resins: moulds and models with precise surfaces ready for the next process.
Plasterboard: trimming of large panels with clean contours.

FCN, FCN-2 or FCN-A: choosing within the range

The FCN is the largest-format option in the family, with up to 3,800 mm of width, 1,250 mm of Z height and an 18-position turret. The FCN-2 adds a twin milling head to work in pendulum mode and double output, with speeds of up to 36,000 rpm. The FCN-A is the reinforced model with linear encoders, geared towards aluminium machining with a precision of ±0.025 mm. All three share the modular concept and dynamic 5-axis control.

Which companies the FCN is built for

The FCN suits mould and model makers, suppliers to the automotive, marine, railway and aerospace industries, and wood and panel manufacturers that need a single centre able to handle large parts, varied materials and changing batches. Because it is built to each customer’s requirements, there is no need to pay for features that will never be used.

Made in Spain and backed by BERMAQ technical service

Every FCN is built piece by piece at BERMAQ’s facilities, entirely in Spain with EU components, and verified to ISO 230-2 before delivery. The service includes pre-sales advice, training, a stock of original spare parts, specialised technical assistance and preventive maintenance packages to extend the machine’s service life.
