Derby 300-400-600

/ 345 axis machining centers

DERBY EVO was born from the the wide experience gained by Fagima in construction of machining centers with moving column. Studied in detail, using the most modern design and calculation systems, it is the best choice that can be found on the market today.

It is characterized by the high rigidity of structures and the absence of the fall on the Y axis. Rapid and high accelerations allow reductions of the cycles times, especially on large pieces. Available in 3 different versions on X axis strokes, 300 version is certainly the most balanced.

The structure starts with a monolithic base made up of enriched mineal casting (with annexed cast iron table) ad it is characterized by a high loading capacity without the needs of very complex foundations.

The column-holder carriage slides on it, through roller guideways (all X, Y and Z axis have such kind of guideways). Inside the column, two groups are located: the toll changer and the exchange arm. The standard configuration of the tools magazine has 42 positions (60 positions as an option). The column has been studied to grant the highest rigidity of the spindle-holder head.

An elegantly styled fairing with 2 front sliding doors gives a marked personality to the new Fagima machine, and a clear separation was ensured between the dry and the wet working area. The standard configuration is susceptible to large expansion and provides most suitable customization of the machine: an example is the turning / milling kit which unquestionably places this model at the forefront, underlining its clear distinction from competing products.

Things to know

Main structures of Derby Evo are made thanks to a new technique, alternative to traditional welded steel, cast iron and granite elements. It starts from making an external shell, that can be entirely or partially filled. The exploited conglomerate has a mix design of elements, specifically worked out to optimise the mechanical characteristics requested by the world of machine tools and machines in general. Several advantages come from this technique, especially for middle dimensions machines like Derby Evo:

◼︎High dynamical stability of the machine
◼︎Non-deformability over time
◼︎Minor vibration in the tool contact area
◼︎Minor thermal generation in the tool/piece area
