WNT milling system improves stability and process security

The 2011-07 milling system from WNT is of particular interest to users of machining and turning centres with high speed spindles but with low torque moments, low powered spindles and turning centres with driven tooling.

With its 7 mm insert edge length, combined with a maximum depth of cut of 6 mm at feed rates up to 0.06 mm per tooth, 2011-07 inserts, and associated cutter bodies, are claimed to maximise the available power to generate maximum metal removal rates.

The 2011-07 inserts also benefit from WNT's latest Hypercoat CVD tool coating system that enables the carbide substrate to operate at elevated temperatures, meaning higher cutting speeds and longer tool life. Supporting these elevated cutting speeds is the fact that every cutter body is equipped with through tool coolant as standard. The cutter body design also maximises the number of inserts per cutter, to allow further improvements in metal removal rates.

To ensure process security WNT has looked at numerous elements of the insert and cutter body design. In particular the use of a notch system on the insert to securely locate the insert onto the cutter body.

With indexable insert cutter available from 10 mm diameter, and inserts available in grades suitable for steel, stainless steel cast iron, heat resistant materials and titanium, 2011-07 is also proving to be a viable alternative to solid carbide milling cutters.
