With the new MP6 geometry, Walter is rounding off its range for the medium machining of steel (secondary application: ISO M, K, S). The MP6 combines features for medium machining, such as a positive rake angle, with those of roughing inserts, such as a tough cutting edge. This makes the geometry a suitable link between the existing MP4 geometry for medium machining (with good chip-breaking on soft steels) and the RP4 geometry for roughing operations (with a tough cutting edge for high feeds).

Walter offers the MP6 geometry in CCMT, DCMT, TCMT and VBMT basic ISO shapes. A short primary chamfer on the cutting edge, which is characteristic of roughing inserts, ensures a high degree of stability, even in challenging conditions like when machining forged parts with interrupted cuts. The 18° rake angle, tough cutting edge and special chip-breaking geometry ensure chip control during medium machining.

Walter specifies feeds from 0.1 to 0.4 mm/rev and depths of cut from 0.4 to 4 mm as the range for the machining parameters. To prevent vibration on thin-walled components, Walter has given the MP6 geometry an open chip-breaker groove, which reduces cutting pressure even when machining at a higher depth of cut. This feature also makes the MP6 suited to unstable components and components with long overhangs, such as during internal turning. Its straight cutting edge makes it suitable for use as a chamfer insert, regardless of the application.

In addition, the new Tiger·tec Gold grades have a positive impact on tool life. WPP10G, WPP20G and WPP30G are adapted to different operating conditions, leading to increased tool life and performance across a broad range of applications.

Tungaloy has 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 high 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. Suitable for shoulder milling, slotting, side milling, pocketing, ramping and trochoidal milling, the size 12 addition to the TungForce-Rec enables manufacturers to extend their machining parameters and material removal rates.

The TungForce-Rec size 12 tool body retains all of the characteristics of the smaller TungForce-Rec 06, including a particularly thick core diameter and heavily supported backing behind the insert. This thick core diameter delivers improved stability during machining, especially 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 design provides greater screw-thread engagement security that ensures tool reliability and longevity when using the TungForce-Rec at high metal removal rates. As a further point, this combination also reduces vibration and improves surface finishes and insert life when machining at increased cutting parameters.

Tungaloy’s new TungForce-Rec 12 boasts a 50% higher tooth density than competing shoulder milling cutters of the same size. For example, this gives a 16 mm diameter cutter three insert pockets, while a 50 mm diameter tool can accommodate 12 inserts. The development allows the new shoulder milling series to run at a higher feed rate than competitor products, reports Tungaloy.

For the precision cutting of components and slots, Floyd Automatic Tooling is introducing the Alesa Nutex Star Mini system to complement the existing line of Nutex saws. The latest addition to the Nutex system incorporates a powerful interface with small shank diameters that helps to extend the application possibilities.

Available with a complete range of saw blade diameters and widths complemented by a comprehensive selection of tool holders, Floyd Automatic says that the Nutex Star Mini system is suitable for all machine shops.

Precision cutting is derived from the saw and holder having an identically ground seven-cam interface. This design makes the mounting of blades a self-centring proposition that is backlash-free. Furthermore, the saws can be supplied hollow-ground or in the proven ‘Plus’ design with side relief angle. The mounting process is rapid and precise credit to a central screw system that enables fast and easy fitting on the long solid-carbide holders.

Notably, the seven-cam design also ensures that cutting forces transmit evenly and tangentially, which enables the transmission of significantly higher cutting forces through the system, especially when compared with rival systems that offer two, three or four driving cams. The benefit for the end user is two-fold with improved precision and process reliability, particularly when cutting challenging materials such as aerospace or medical-grade alloys that demand increased torque.

To enhance swarf removal and prolong tool life, Alesa has developed the Nutex Star Mini system with through-coolant supply. The internal coolant supply delivers coolant directly to the saw surface via internal cooling channels in the tool shanks. These tool shanks are manufactured from steel or, optionally, solid carbide to enhance rigidity, performance, vibration dampening and tool life.
