MECAL MACHINERY s.r.l.

3-axis CNC+ 1 axis pneumatically managed floor-type vertical spindle machining centre, suitable for working aluminium and PVC profiles. This new Mecal machining centre, presented on last November for the first time, is equipped with a 3,8 kW electro spindle arranged for the quick-change tooling and with a 5-position tool magazine with automatic tool change. The workpieces are fixed with 4 pneumatic clamps, sliding on the tilting beam; this beam has a ±90 ° rotation range with pneumatic actuation. The locking clamps slide on precision guides, with manual positioning supported by a laser indicator managed by CN. The axis slide on precision linear guides and transmission through rack-pinion; the positioning is done by brushless motors with absolute encoder, managed by CN with a high-speed digital system. The locking clamps slide on precision guides, with manual positioning supported by a laser indicator managed by CN.

The 5-axis machining centre Geos MDT is characterised by extremely high machining capacity and, as in the case of the mitre saw, utmost versatility: the 18-position, rotary tool magazine is on the machine movable post and enables to reduce significantly the transition times between different machining types. The machining centre is equipped with a cutting module (MDT) devised to machine profiles completely, including the extruded bar sectioning and facing. The use of digital electronics enables to apply fibre optic for the data transmission, which guarantees high speed and total absence of interferences due to external factors. The motorised vices for locking the piece are independent and can be simultaneously positioned in very short times also during the machining cycle, to speed up production and to guarantee high accuracy standards of the finished product. Profile cross sections up to 550 x 380 mm with lengths depending on the underframe size of 7.800 – 13.990 mm can be machined. With the pendular mode the machining times are really very reduced; however, the user software is the biggest advantage. From 3D machining drawings can be generated with few “clicks” complete machining programs, which again make the user’s operation of the Geos considerably easier.
