The CL EXTREMA machining center produced by SYSTEM ROBOT AUTOMAZIONE SRL is a 5-axis CNC machine, designed for high-precision machining on materials such as aluminum and composites. This 2008 machine is particularly suitable for the aerospace, marine, railway, ground transportation and energy industries thanks to its ability to process large structural components and complex shapes.
The CL EXTREMA machining center is equipped with a mobile portal structure with Cartesian axes, which guarantees great rigidity and stability even under dynamic stress. The machine stroke is 4000 mm on the Y axis, 3000 mm on the " or customized structures.
The heart of the machine is a 30 kW electrospindle, capable of reaching a rotation speed of 22,000 rpm, ideal for high-speed milling of aluminum and laminated materials. The machine includes an automatic tool changing system with a capacity of 8 tools with HSK 63A cones. The control is entrusted to a SELCA S4045 PDH system with 3D incremental encoder, which allows precise and continuous management of the axes and the use of oriented tools, including rigid tapping.
The CL EXTREMA is designed for processes that require high removal capacity, maintaining high precision. It is ideal for milling on glass or carbon fiber reinforced materials and can be used for complex molds, patterns and structural components. To use the machine, it is necessary to correctly configure the parameters in the numerical control, select the appropriate tool and set the speed and feed rates according to the material to be machined. The feed speed reaches 70,000 mm/min on the X and Y axes and 60,000 mm/min on the Z axis.
Among the accessories that can be combined, we find dust extraction systems, cooling devices, and laser measurement systems for tool calibration. For optimal maintenance, it is important to keep the tracks and lubrication systems clean, regularly check the wear of the tools and monitor the condition of the electrospindle.
To evaluate whether a used CL EXTREMA machining center is a good choice, it is essential to check the condition of the guides, the spindle, and the electronic components. A thorough inspection of the structural integrity and capabilities of the control system will help determine the overall condition of the machine. Buying a used model can offer excellent value for money, especially if accompanied by a 12-month warranty as offered by trusted retailers
