The SMART 3015 is a three axis Cutting Centre primarily intended for contour cutting. A laser beam is directed towards a focusing head that moves horizontally along a gantry on the X axis. The focusing head of the beam moves vertically on a platform along the Z axis. The X axis gantry moves horizontally the Y axis. The BA cutting centre uses rack & pinion to move the gantry. These are synchronized through the use of an electronic device. All axes are ball screw driven. The table carrying the parts is fixed. All the movements along the 3 axes are numerically controlled.
The primary structures of the SMART 3015 Cutting Centre are made of thermally stabilized welded material. The various components that make up the structures of the machine are assembled with a degree of precision compatible with the desired mechanical characteristics.
Precision ground, hardened steel ways having a rectangular section are used to support all the axes. The ways are protected from impacts and contamination by using metal shields or bellows. The motion guides can be placed in a slightly pressurized enclosure to protect them against certain aggressive environments.
All the axes include rack & pinion and are driven by Siemens AC servo drives and motors. The drive motors are installed so that mechanical play is eliminated when changing the direction of movement along the axis.The electrical energy delivered to the motors is controlled by transistorized variable speed devices. (PWM).
The optical path is that path that is travelled by the laser beam between its point of entry into the frame of the Cutting Centre and the point where it leaves a nozzle placed after the focusing lens.
The beam enters from one side of the movable gantry. It then reaches a totally reflecting mirror angled 45° with respect to the surface of the object carrying platform. The mirror is installed in a three dimensional adjustable device which sets the vertical direction of the beam on the focusing lens placed at the base of an optical guide.
The focusing lens is placed in a work head. The nozzle from which the beam emanates is located at the bottom of the work head.
Once the laser beam enters the work centre it encounters 3 optics (2 mirrors and 1 lens).
The inside space separating the focusing lens from the tip of the nozzle is protected by a pressurized assist gas that flows from the nozzle.
The work head is installed on an automatic profile tracking device which ensures a consistent focal distance (between the lens and the surface of the machined material). The entire optical path can be pressurized to prevent the entry of gases that would contaminate the mechanical and optical components. Depending on the power of the laser, it is possible to cool the optical components placed along the path of the beam to protect them against any excessive heating. The machine is supplied with total reflection mirrors and a focusing lens.
The exhaust of possible smoke or light residues as a result of machining is provided for through specific ducts whose pickup point is placed at the bottom of the object carrying platform. The link between the suction duct and the air exhauster (available as an option) is provided for.
