The machine is equipped with a suction hood mounted on the electrospindle, which can be connected to a centralized extraction system or an industrial vacuum to effectively remove chips and dust generated during milling. The hood is motorized, and its height is managed directly from the operator panel based on the tool length.
• Suction hood for collecting machining chips
• Pneumatic engagement and disengagement of the hood
• Motorized hood height adjustment, controllable via operator panel
• Connection manifold for suction hose

The machine is equipped with a laser protection system that defines the working area during machining, along with rigid guards near the electrospindle to protect against material projection. This solution eliminates the need for bumpers on the bridge or safety mats with sensors.
Additionally, SLS and STO safety systems are integrated, which regulate machine speed during specific operations and disable motor torque in emergency situations.
• Safety laser scanner
• Rigid guards on the bridge and electrospindle
• Safety function with Safely Limited Speed (SLS)
• Safety function with Safe Torque Off (STO)

The machine is equipped with a three-axis system designed to ensure precision and excellent dynamics. The axes are driven by high-precision brushless motors and a gantry system with rack and pinion, guaranteeing smooth, fast, and accurate movements.
