The latest milling system from WNT (UK) further enhances the Sheffield-based cutting tool specialists reputation for delivering cost-effective and highly productive cutting tool solutions to its customers.
The introduction of the 2011-07 milling system is of particular interest to users of machine tools (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 feedrates up to 0.06 mm/tooth, 2011-07 inserts, and associated cutter bodies, offer distinct advantages to users of this type of machine tool, maximising 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 deign. In particular the use of a ‘Notch’ system on the insert securely locates the insert into 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. With one cutter body suitable for cutting a wide variety of materials, just by changing the insert grade cutter stocks can be dramatically reduced. In addition, 2011-07 further reduces consumable cutting tool costs by eliminating the requirement for expensive regrinds and the management of that process.
