Efficiency redefined

Excessively high feed rates can cause uncontrolled vibrations, thermal overload of the spindle bearings, or, in the worst case, tool breakage. As a result, machines are often operated well below their actual potential. 

This is where the experts at Pokolm came in. They developed the Fourworx® high-feed milling cutter, which promises four times the performance in rough and medium-duty machining of various materials.

Fourworx®’s technological superiority is based on a modified force distribution. The sophisticated geometries of the tool and cutting inserts enable a 50% reduction in stresses within the tool. 

Less stress in the tool also means significantly less load on the spindle bearings and a reduction in thermal stress. The result is a significantly extended machine service life. This allows cutting parameters that were previously reserved for high-performance machining centers to be achieved even on machines with lower specifications or with unstable clamping setups.

This high number of teeth in a very compact space is the key to process stability: The load is distributed across more teeth, which drastically improves smoothness. Even with the smallest tool diameter of 16 mm, three cutting inserts are used. In practice, this means higher feed rates while minimizing the risk of failure.

Fourworx® truly shines in deep cavities and when machining unstable workpieces. The innovative 3D chip pocket, combined with the standard internal coolant supply, ensures highly efficient chip evacuation. Even in deep pockets, chips are not cut multiple times, which significantly extends the service life of the four cutting edges. 

Fixed cutting inserts, a negative insert seat, and the geometry of the carrier ensure that cutting forces are transmitted axially directly into the spindle. This minimizes radial forces and the associated radial vibrations. The result: a smooth cut and positive effects in deep cavities.
