4-axis CNC machining centre with moving gantry structure, designed for drilling, milling, threading at any angle from -90° to +90° on bars or workpieces of aluminium, PVC, light alloys in general and steel. The 8,5 kW electrically-driven spindle with ISO 30 tool holder allows machining operations, including heavy-duty work, with optimum results in terms of speed and accuracy. The machine can be used in double mode (7000 model) so as to minimize machine downtime, as it is possible to change the workpiece (load/unload) in “cancealed” time. It is also possible to load and consequently machine different workpieces between the two working areas. The automatic tool magazine is available in a fixed solution on board the machine with 4/8 places, recommended for multi piece machining. Also available a 12-place automatic magazine on board the carriage, ideal to allow a faster tool change and useful for the double mode machining. The gantry is provided with a guard which, besides protecting the operator, also reduces the noise impact on the environment.

Configurations with 12-place automatic tool magazine on board the carriage
Configuration with one 4-place fixed tool magazine
Configuration with one 8-place fixed tool magazine
Configuration with 7-place fixed tool magazine
The automatic tool magazine comes in two different configurations. The first has one or two fixed 4/8-place magazines installed on the left-hand side of the machine and is specific for operation on a single work area in single or multi-piece mode. The second configuration excludes or integrates the fixed magazines, with an automatic 12-place magazine installed on the carriage moving on the X axis. This solution, required for machining in double operation mode (mod. 7000 mm only), considerably reduces the tool change times and consequently increases the machine productivity and efficiency.
The vice unit can ensure the correct and safe clamping of large aluminium, steel and light alloy profiles. The vice size and the long Y stroke of the electrospindle allow machining large profiles for all kinds of civil and industrial applications. Each unit slides on special linear guides on machine surface. The positioning is managed by the X axis. Counterblocks can be mounted quickly and accurately, making the machine extremely versatile. The vice unit is available optionally in double hold-down device version to machine two profiles in parallel.
The machine is equipped with two sturdy and precise pneumatic reference stops, used to machine one or two profiles in multi-piece or double operation mode (model 7,000 only). A laser system is available for accurately positioning the workpieces on the work surface; it reads each profile and sets the reference without the need for mechanical stops.
If necessary, it is possible to install additional vices beyond the standard machine equipment. In this way, it is possible to ensure perfect clamping of bars or bar sections even in complex cases in terms of number, size or types of profiles to be machined. Moreover, the additional vices allow greater versatility in vice position depending on the length of the workpieces and the machining to be performed.
The machine can be optionally equipped with an electronic device that automatically corrects workpiece dimensional errors in length, width and height. In this way, the accuracy of the machine is not influenced by the differences between theoretic and actual workpiece dimensions during machining. This device accurately probes the rough workpiece in several positions, correcting the machining along its whole length, even with deformed or warped profiles.
