AluStep for milling wood, plastic, resins and metals

Alustep can perform two-dimensional cutting and engraving milling, and three-dimensional milling such as bas-reliefs and complex geometries.

The powerful 7 kW spindle at 40.000 rpm and the large work surface make it a CNC pantograph excellent for large format work on: wood, plastic, resins and light metal alloys.

AluStep components

  1. High speed spindle
  2. Machine console with XMC CNC interface
  3. Doors on each side
  4. High speed and stiffness mobile bridge
  5. Automatic tool changer with 15 tool stations
  6. Removable top cover
  7. Removable drawers for the collection of machining chips

High speed electrospindle

AluStep is equipped with a powerful 7 kW electrospindle at 40.000 rpm which allows you to carry out milling and engraving jobs on a wide range of materials. The HSK 40 cone attachment allows you to always have a rigid and balanced hold on the tool.

Worktop with mechanical and vacuum fastening

The ground aluminum worktop ensures a perfectly flat work surface. Thanks to the steel threaded inserts, the pieces can be firmly fixed mechanically, while the texture of the worktable and the powerful vacuum pump allow an exceptional vacuum fixing for both large slabs and small pieces.

OSAI control system

AluStep is equipped with a latest generation OSAI integrated system consisting of: axis motors, CNC drives and command console (HMI). The HMI operator interface allows you to have all the commands necessary for piloting AluStep, making it possible to: import machining, analyze the project from the 2D/3D preview and start machining. The machine is fast and precise, while still guaranteeing a high degree of ease of use.

Available optional

Pneumatic tangential head with oscillating blade

The tangential oscillating blade offers an additional tool to obtain a precise and clean cut on medium density and hard materials with thicknesses up to 100 mm. Through the pneumatic disengagement, the head can be easily activated or deactivated according to the processing needs.

Interpolated fourth axis

Fourth continuous interpolated and indexed axis, with 4 dependent jaws sealing system for cylindrical machining. Rotation supported by precision cycloidal gearbox and brushless B-axis motor with encoder.

Suction system for workpiece fastening

Worktop with suction holes for holding the pieces being processed and suction system with vacuum pump, silencer for noise reduction. Ease of operation, maintenance and installation.

Mechanical probe

Retractable probe with radio transmission for measuring and centering the piece.

Print marks camera
