Tool manufacturer Pokolm Frästechnik describes the latest addition to its milling cutter portfolio as the high-performance milling system for roughing and prefinishing applications in the field of high-feed machining. With FOURWORX, milling specialist POKOLM claims a multitude of interesting properties that will enable users to advance into previously unattainable realms of performance.

The extra performance is made possible by the completely redesigned overall geometry of the milling system. The significant outcome is that even the smallest tool diameter of 16 mm boasts three inserts. With this branch novelty, cutting depths up to a_p 0.75 mm and feed rates up to f_z 1.2 mm/teeth can be achieved. And despite the small tool diameter, the innovative geometry enhances stability.

Similar attributes apply to the inserts. Despite the compact dimensions, a clearly visible and innovative reinforcing collar around the screw seat, together with a negative insert seat, provides for an extended service life. At the same time, chamfered outer edges protect the inserts against spalling around the circumference. A 3D chip pocket optimizes chip removal and cutting performance.

The corner radius of 1 mm stands for stability at the outer tool diameter – even at high feed rates. The extremely precise inserts possess four cutting edges. In four different grade/coating combinations and with two chip-breaker grooves, they allow the machining of a broad range of materials and are suitable for the machining steel, cast iron and SAH materials, such as titanium and Inconel.

Overall, the innovative system design leads to considerable reduction of the stress in the tool and to significantly enhanced stability, according to the company.

Even on less powerful machines, FOURWORX milling cutters enhances performance. Similarly, the new milling system also proves its capabilities with fragile workpieces and in deep cavities, both in wet and dry machining.

FOURWORX is available in diameters 16 to 42 mm as endmills, threaded-shank mills and with POKOLM's patented DUOPLUG system for optimised concentricity and maximum rigidity. All tools feature an internal coolant supply for process reliability.
