Aluminum double-miter cutting-off machine COMPOUND CUT

for profilesCNC

Twin-head cutting-off machine with 9 controlled axes which include the automatic movement of the mobile head, electronic management of two rotation axes of the cutting units, blade feed and vertical translation of the cutting units to maximise the work area. It allows reaching angles from 45° (internally) to 22°30’ (externally) on horizontal axis and from 0 to 45° on vertical axis with decimal cutting precision. The feed of 600 mm widia blades can be carried out on two axes, optimising the cutting chart in the vertical direction, to cut profiles more than 500 mm in height and ensure an optimal adjustment of blade exit speed and stroke. The HS (High Speed) version has a higher speed X axis and all the protections required for automatic machining operations, also with the machine unattended. The inclination of each head, up to 22°30’ outwards, is obtained by means of a mechanical transmission with high-precision gear motor and brushless motor with absolute encoder. The tilting is performed by means of an electric actuator with recirculating ball screw and brushless motor. To ensure an optimal positioning, the positioning accuracy is checked upstream of the kinematic transmission chain, through a rotary absolute encoder. The blade feed is carried out on two axes. The vertical translation, associated with the blade exit movement, increases the cutting diagram height dimension significantly, allowing for maximum use of the large diameter of the blade. The tool trajectory is managed by the software based on the cutting program, on the profile and on the head inclination.
