PowerMax

Camozzi Machine Tools large format, 5/6 axes, horizontal platform for hi-accuracy and high-feed rate milling of Aluminum and Titanium.

PowerMax is a large working volume, 5 axes (6 in case the rotary table is selected), horizontal, subtractive manufacturing center for Aluminum and Titanium parts.

PowerMax’s 3 linear axes travel along parallel sets of linear guides and optical scales mounted to thermally-symmetric sub-structures, driven with high-torque, high-power, coupled gear-motors controlled via Siemens, Fanuc, or Heidenhain CNCs. The same approach has been adopted for its C and A axes.

These choices for its design assure to PowerMax superior static and dynamic positional accuracies at high speeds and accelerations in its working envelope for a constant chip removal rate throughout the entire milling volume.

The design provides PowerMax with superior static and dynamic positioning accuracies at high speeds and accelerations in its working envelope for a constant chip removal rate throughout the entire milling volume.


Kinematic Configuration is partially reversed

The milling head moves:
- horizontally along X with the column
- vertically along Y within the column
The part being milled moves horizontally along Z axis on the pallet.

In the 6 axes version, the pallet is replaced by a moving rotary table.


Benefits

  • Feasibility
    Manufacturing of complex geometry Al and Ti parts
  • Quality
    Tight tolerances and surface finishing throughout the entire working volume
  • Capacity
    Large milling volume
  • Productivity
    Reduced machining time
  • High ROI/Low TCO
    Low capital investment and low operational cost

Features 

Three versions

PowerMax S for Aluminum
PowerMax S for Aluminum

Two polar axes heads with electro spindles with torque up to 100 Nm and power up to 125 KW.

The stiffness of the PowerMax allows it to keep a constant feed rate when machining in 3, 4, 5, or 6 axis, holding the dynamic tolerance while milling on 3D surfaces.

Dynamic tolerance is the maximum allowed difference between the given tool path and the followed path by the machine (accuracy on machined part).

Good dynamic is needed to be fast and accurate. Good dynamic can be obtained only out from a specific structure and performing kinematics.
