Tungaloy adds insert density and speed to shoulder milling series

Related Vendors

Cutting tool manufacturer Tungaloy has now expanded its Tungforce-Rec Series of square shoulder milling cutters to include size 12 inserts and associated tool bodies.

The Tungforce-Rec range is a high-density shoulder milling cutter with a secure insert clamping system that boasts excellent process security. Incorporating all of the benefits of the existing size 06 V-bottom Tungforce-Rec inserts, the new size 12 inserts offer an extended cutting edge length that is twice as long as the existing size 06 inserts. Perfect for shoulder milling, slotting, side milling, pocketing, ramping and trochoidal milling, the size 12 addition to the Tungforce-Rec now enables manufacturers to extend their machining parameters and material removal rates.

The Tungforce-Rec size 12 tool body retains all of the impressive characteristics of the smaller Tungforce-Rec 06. This includes a particularly thick core diameter and heavily supported backing behind the insert. The thick core diameter delivers improved stability during machining, particularly when cutting at elevated speeds, feeds and depths of cut. Likewise, increased support behind the insert permits the use of longer insert clamping screws. This provides greater screw-thread engagement security that ensures tool reliability and longevity when using the Tungforce-Rec at high metal removal rates. This combination also reduces vibration and improves surface finishes and insert life when machining at increased cutting parameters.

The new Tungforce-Rec 12 boasts a 50 percent higher tooth density than competing shoulder milling cutters of the same size. For example, this gives a 16 mm diameter cutter 3 insert pockets and a 50 mm diameter tool can accommodate 12 inserts. This new development allows the impressive new shoulder milling series to run at a higher feed rate than competitor products.

The Tungforce-Rec 12 offers cylindrical shank tool bodies available with standard or long length shanks for additional reach into cavities and difficult to access faces. Furthermore, the series is available with modular heads with a self-centring screw coupling and also as shell mills. Tungaloy has introduced a total of 26 inserts in geometries that include the MM style for general-purpose machining with a nose radii ranging from 0.4 to 3 mm and also the AM style for aluminium alloy machining with a nose radii of 0.4 and 0.8 mm.
