The 2+4 EVO reducing and sizing mill uses a patented pass design. A reducing group with 2-Roll stands with high reduction is followed by a sizing group with 4-Roll stands with low reduction. While the 2-Roll high reduction guarantees the desired metallurgical structure, the 4-Roll low reduction provides excellent surface finish and size tolerance.

The mechanical action used to break the particles and reduce the size can be diverse and different mill exist that will use the milling principles. Use of 2 solid surfaces : the solid is pressed or frictionated against 2 solid surfaces. The solid is cut - Shear forces or pressure waves are used to break the particles.

To mill pocket corners or arcs, using a smaller diameter tool and programming it to required drawing radius, thus controlling arc of engagement in single or multiple passes, aids in reducing chatter. On the other end of spectrum, sometimes too low chip thickness makes the cutting edge rub part surface as opposed to cutting it, causing ...

As the end mill enters the corner, the percentage of engagement increases the number of teeth in the cut. This drastically increases the cutting forces, causing chatter. To reduce chatter when machining corners, consider using circular interpolation to produce a bigger corner radius than indicated by the part print.
