MECAL MC 304 ATLAS CNC Profile Machining Center

Cantilever type vertical spindle CNC machining centre designed to work on extruded aluminum and light alloy. Machine can be configured with 3 or 4 CNC axis.

The machine is equipped with a 5,5 kW, 18000 rpm electro-spindle with ISO30 tool holder system and a 8 positions tool magazine.

CNC unit of the machine performs milling operations through linear and circular interpolation (compound movements) on 3 axes (X-Y-Z). Axis A is the spindle rotation axis that allows the spindle to be tilted on any angle within ±90° around X-axis. This enables processing on any angle within ± 90°. Spindle can work on 3 faces with standard tools and work on both ends with disc cutter (end-milling operations). 

Programming is done by using Mecal’s geometrical assisted CAM software Mecal CAD3D as well as standard ISO codes.

Two machining zones can be used independently (pendular mode) so that loading/unloading times are masked and machining length is used efficiently.

  • Cantilever type vertical spindle CNC machining centre
  • Axes drive system is consisting of a servo controller and a brushless DC servomotor. Position is tracked by an incremental encoder integrated in the drive motor
  • Work piece clamp bars slide on precision linear guide rails
  • Working area can be divided in two zones so that two separate working stations can be utilized
  • By using the disc cutter, it is possible to carry out end-milling operations on both the ends of the work piece
  • Milling operations are performed with linear and circular interpolation of the X-Y-Z axes
  • Pneumatically operated flipping reference stops
  • Tool magazine is mounted on the mobile upright beam and travels with it. This allows a quick tool change operation during machining
  • Tool cooling via Minimum Quantity Lubrication
  • All slide ways and ball screws are lubricated through an automatic central lubrication system
  • Front light curtains and side/rear safety metal screens
  • Capability of machining composite door panels via special wide grip clamps and a suction hood around the spindle

  • Available standard lengths: 7400mm (24.3') / 9400mm (30.8') / 11400mm (37.4')
  • Spindle power: 5.5kW
  • Spindle rotation speed variably up to 18000 rpm
  • Tool clamping system is ISO30
  • 8 positions tool magazine
  • Clamps open to a fix stroke and accommodate components up to max. 650mm (25.6") width
  • Electronic NC interface with a PC running on Windows 10 OS.

  • Electric spindle air cooled, ISO30, 18000 rpm, 5,5kW
  • Tool magazine with 8 tools capacity
  • 4 x Pneumatic clamps
  • Drawers for chips collection
  • Start up tool kit
  • Front light curtains and side/rear safety metal screens
  • Electronic NC interface with a PC running on Windows 10 OS.
  • CAD CAM 3D Graphic software

  • Automatic Positioning Clamps (MMI). Each clamp bar is equipped with a brushless DC motor-reducer assembly. Therefore, each clamp bar becomes an independent axis controlled by CNC unit. The program will display the locations for the clamps. With the confirmation of the operator, clamps are positioned simultaneously.
  • Extra clamps (DPM or MMI)
  • Set of two intermediate stops to allow working with max 4 parts loaded on the machine
  • Extra tool magazine for aggregate tools
  • Probe for the automatic detection of the tool length
  • Bar code reader
  • Electrospindle 7,5 Kw
  • Electrospindle 7.5 Kw with encoder
  • CAM 3D Machining simulator
  • Drawer set for the chips and scrap pieces collection
  • Interface drive for third party window making software
  • CADLink 3D Driver to import STEP or IGES files
  • Horizontal 2 spindle aggregate
  • Saw blade aggregate Ø 120 – 215 mm (∅ 4¾" - 8.46")
