The P45 CNC end milling machine has been designed to perform a partial contouring operation on the profile head. . This operation allows to prepare the profile for the next welding operation with the result of obtaining a seamless fusion. Thanks to its 3 interpolated axes and a specially shaped milling cutter, the machine performs the milling following the profile shape previously loaded on the CAD-CAM. The machine can accommodate 4 profiles simultaneously in order to optimize cycle times. Thanks to the powerful CAD-CAM that works on a 3D basis all the operations can be easily edited by configuring speed, feed and displacement parameters. The 3D graphics give back to the operator the real removal that the machine will then perform limiting programming errors and possible collisions.
