New A2520 series from WNT for Titanium Milling

Added to MTDCNC by WNT (UK) Ltd on 15 March 2013

The latest range of indexable insert milling cutters from WNT is aimed at high performance machining of titanium, superalloys and stainless steel components. By providing a stable and robust insert location, along with eight cutting edges per insert the A2520 series offers increased performance, productivity, and security when machining these materials.

The cutter bodies are designed to handle a wide range of milling operations, including slotting, turn milling, face milling and reverse copy milling and are available with cylindrical, screw thread or shell mill style shanks, all with through tool coolant as standard. Cutter diameters range from 32 mm to 80 mm dependent on the style of body selected, with each body accepting the new round (RHNU) inserts.

The double-sided inserts feature a series of four precision indentations around their periphery to enable accurate indexing when the edge becomes worn, giving eight cutting edges per insert. The insert geometries have undergone extensive development in order to achieve optimum performance and simplify the machining process on these ‘difficult to machine’ materials.

For titanium, stainless steel and super alloys there is the M31 geometry that features a deep chipbreaker that creates ideal chip formation at elevated feed rates. It also has a highly positive geometry for a smooth cutting action and quiet machining. The M31 geometry inserts are available in two grades, HCN5235 and HCF5240.  When machining martensitic heat resistant Cr-Ni steels the geometry of choice is M32, which is designed with wider chip pockets to assist swarf removal in high feed applications. These inserts are only available in grade HN5235.

The combination of robust cutter bodies, insert geometries designed for these materials ensure that the 2520 series of button insert cutters will deliver volume metal removal thanks to high performance cutting data of up to 0,6 mm per tooth feed rates, and a maximum of 3 mm depth of cut (theoretical 5.5 mm). This makes them ideal for a wide range of applications in the aerospace, automotive and general engineering sectors.
