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.

With meticulous attention to detail, the team at Subi Performance is technically ahead of the curve as it applies its creativity to set new standards in the tuning, assembly and repair of high-performance combustion engines. To support the company’s growth trajectory, it has invested in Big Kaiser spindle tools that are available in the UK from Industrial Tooling Corporation (ITC).

“I had to rebuild the end bearing on a Subaru boxer engine, which required a boring head,” says Andre Wojtkowski, founder and owner of Subi-Performance. “I came across the spindle tools from Big Kaiser, a company belonging to the Big Daishowa Group. In an e-mail, I described my problem to Jochen Renz, the technical manager at Big Daishowa and later we spoke on the phone. He applied his extensive know-how and suggested the Big Kaiser SW 53 tool might be the perfect fit for reverse machining.

“What can I say – the tool turned out super and the final result exceeded all my expectations,” he adds. “And since my business revolves around special tasks related to engines, I then made an appointment with Stefan Lenhart, a Big Kaiser application engineer to talk about future projects and possible uses of other tools in the range.”

Utilising fine-boring heads from Big Kaiser, Subi-Performance now covers the entire diameter range from 20 to 203 mm, starting with the EWN 20 and EWN 32 for machining camshaft lanes, as well as the EWN 41 for crankshaft bearing lanes and the EWN 68 for cylinder fits.

At Subi-Performance, the Smart Damper is used in combination with complete spindle tools. The special feature of the Smart Damper is its dynamic damping system that eliminates vibration when using long tools.
