Mecal “MC 316” fabrication centre has been designed for automatic milling, drilling, tapping and cutting operations on aluminum profiles. The unit consists of a loading magazine, servo material pusher, machining station, cutting station, and motorized unloading table.
The operators will load multiple stock lengths on the in-feed table. The profiles are fed one at a time through the rotating ring style (turret) milling/drilling station equipped with multiple electro-spindles. Machine features horizontal and vertical clamping systems to hold down the extrusion during the machining and cutting. After the milling, the pusher advances and the cut is performed by a ∅ 550mm (21.6″) blade capable to make straight, miter cuts and notches. After cutting, the parts are transferred onto a belt conveyor which then carries them out from the cutting station. A pneumatic pusher will move the parts cross wise on the out-feed table.
Mecal “MC 316” is a feed-trough aluminum CNC fabrication centre designed for milling, drilling, tapping and cutting operations on aluminum profiles. The whole system consists of a loading magazine, servo material pusher, machining station, cutting station, and motorized unloading table.
The operator loads multiple stock lengths on the in-feed magazine.
Operator aligns the profile by using the reference plate located on the right end of the table as well as by pulling the profile towards him against the reference stops.
Motorized belt conveyor advances until the first profile reaches the feeding area, then pneumatic alignment rollers clamp and align the extrusion.
Profiles on the loading table are automatically fed into the machining and cutting unit by a servo controlled pusher. The linear motion system is consisting of profiled linear guides, linear bearings and a high precision helical rack and pinion drive.
The pusher is equipped with a gripper arm that can be adjusted both vertically and horizontally by servo motors. Optionally, the gripper arm can also rotate around its axis within 0°-180°.
Low friction plastic rollers avoid any possible scratch supporting the profiles while fed in the milling and cutting stations. Vertical rubber rollers properly guide the extrusions during the feeding process.
The milling/drilling unit features a rotating ring (turret) equipped with 4 electro-spindles (6 as optional). The turret can rotate continuously from 0° to 380° (-190° +190°) controlled by CNC. Tool cooling is provided by an MQL (Minimum Quantity Lubrication) system. The profiles are automatically fed one at a time through the rotating turret. An horizontal and vertical clamping systems holds down the extrusion while performing machining and cutting operations in order to minimize vibrations.
After the milling, the pusher advances and a 550mm blade performs straight, miter cuts and notches. The cutting unit features a CNC controlled descending motion as well as horizontal and vertical clamps. Venturi type blade lubrication.
A narrow belt conveyor carries the machined part out of the cutting station. When the part is completely ejected, the conveyor belt stops and the pusher moves the finished part on a motorized cross belt conveyor that will advance step by step. These belts are wear resistant and have low friction coefficient.
Mecal “MC 316” feed-trough aluminum CNC fabrication centre is the ultimate goal for the manufacturers that are looking to maximize their volumes along with the automation, thus the ideal solution for aluminum window manufacturing.
