Walter, with operations in North and South America, has introduced a new version of its Walter Prototyp Proto·max ST high performance, solid carbide milling tool. It is designed for optimum performance on steel with secondary applications in stainless steel.
The Proto·max ST Z-5 is well suited for dynamic milling, which maintains a constant tool-engagement angle. This allows large depths of cut to be taken, fully utilizing the entire cutting edge of the tool. This is normally combined with radial chip thinning, accomplished by taking a small radial depth of cut; around 10-15 percent of the tool diameter is actually engaged in the cut.
This combination allows for very high speeds, plus very high feed rates and deep depths of cut, typically leading to high material removal rates and lower cutting forces.
