Dormer Pramet’s family of economical milling tools has been enhanced with several new ranges for semi-finishing and finishing in die and mold applications. The launch features an assortment of CNHX05 double-sided inserts, with up to four cutting edges. Its unique patented wiper edges generate a high-quality surface finish, resulting in reduced machining time in both shoulder and face milling applications.
This is supported by a range of SCN05C cutters for productive copy milling of steels, hardened steels and cast irons. Available in 12mm-20mm diameters, the tool’s close pitch increases the number of teeth and enables at least 20 per cent higher productivity than standard pitch cutters.
It has been designed for contouring, profiling, plunging and face milling applications. Offering decreased levels of vibration, the tool has been optimised for smooth cutting of corners and pockets.
Meanwhile, Dormer Pramet has launched an insert with six-cutting edges, the double-sided WNHX04 insert. This too features a unique patented wiper edge to generate superior finish on component walls and face, reducing time in cut. This latest insert is compatible with a new range of economical and productive copy milling tools. The SWN04C cutter, available in diameters between 20-35 mm, offers a variety of differential pitch options to enhance surface finish and support the six-cutting edge insert.
Designed for smooth cutting in operations with long overhang, it can be used in contouring, profiling, plunging and face milling applications with a depth of cut up to 2 mm. As with the SCN05C cutter, the SWN04C range is suitable for semi-finishing and finishing applications in steels, hardened steels and cast irons for the mold and die segment.
In a recent example, the WNHX insert with WM geometry and new M4310 grade was used to machine tool steel at 0.50 mm depth of cut. With a cutting speed of 196 m/min and feed rate of 3,600 mm/min, the tool reduced machining time by 45 per cent, compared to a competitor’s equivalent.
Dormer Pramet, a global manufacturer and supplier of tools for the metal cutting industry, will exhibit its wide range of products at IMTEX 2019, to be held in January 24-30 in Bangalore.
The company’s comprehensive product program encompasses both rotary and indexable drilling, milling, threading and turning tools for use in a wide variety of production environments. Its products are used in a diverse range of industries all over the world, from maintenance departments and fabrication workshops to international suppliers for the railway, automotive and aerospace industries.
