Allied Machine and Engineering, a manufacturer of hole-making and finishing cutters, has added new sizes to its AccuThread T3 thread-mill line. AccuThread T3 is now available in larger UN and ISO sizes up to 1”-8 and M24x3. Machine coding for the new sizes is included in Insta-Code, Allied Machine’s online thread-mill program generator.

Targeting high-production facilities, tool and die industries and high-temperature applications, the additional AccuThread T3 thread-mill sizes create a high-quality thread without the concern of breaking the tool in an expensive workpiece. Allied designed the tool to only machine three threads at a time, which reduces pressure and dramatically increases the chances of tool survival.

The AccuThread T3 is for machining hardened or hard-to-machine materials such as stainless steel, tool steel, and high-temperaturealloys in classifications P, S, M, H, K and N.

According to Allied the advantages of the thread-mill line include: improved tool life and a more precise thread form; the ability to cut harder materials and produce deeper threads than a standard thread mill; and improved cycle time and tool life.

Among notable features is left-hand cutting, which allows the tool to climb mill while it moves from top to bottom, creating a right-handed thread. Further features include the use of three teeth that cut minimal threads all at once and reduce side deflection, along with AM210 multi-layer PVD coating.

Among industries set to benefit are aerospace, agriculture, automotive, firearms, construction, marine, mining and renewables.

Milling challenging materials like tough steels, stainless steels, superalloys and titanium causes built-up or notched edges and broken inserts that increase tooling costs and cause unexpected downtime. To overcome these challenging ISO P, M and S materials, the next-generation Seco High Feed SP milling system features a combination of dedicated cutting geometries and insert grades, as well as optimised lead angles that combine to boost material removal rates, maximise chip evacuation and extend tool life.

According to Seco, one High Feed SP tool can handle a complete range of high-feed milling operations and materials. The tool optimises such operations as copy milling, ramping, pocketing, face milling and plunging to further reduce tooling inventories.

“Premature tool wear increases job costs and leads to unexpected machine downtime that lengthens production time,” says Benoît Patriarca, global product manager -high feed milling at Seco Tools. “The combination of dedicated cutting geometries and grades with optimised lead angles of the High Feed SP system allows for faster machining to shorten job turnaround times, while also providing a superior price-to-performance ratio.”

Designed for ease of use, High Feed SP milling tools provide simple fool-proof insert indexing that prevents operator mistakes, unexpected machine downtime and scrapped parts. Plus, users can quickly access product information through the Seco data matrix code scanning.

Seco offers a comprehensive range of High Feed SP tool sizes. The series includes:SP10 – two geometries, 10 grades, 32 to 63mm diameter; SP14 – two geometries, 10 grades, 50 to 100mm diameter; and SP18 – two geometries, 10 grades, 63 to 160mm diameter.

Horn has introduced two carbide grades for inserts used in its DAH82 and DAH84 high-feed milling systems, enabling their use for a wider range of materials. The expansion gives customers the ability to choose grades best adapted to their applications.

The new SC6A grade is suitable for machining materials in the ISO M group (stainless steels), as well as ISO S materials (superalloys) as a secondary application. The new IG6B grade is for machining ISO P materials (steels), while it is also suitable as a multi-purpose grade for other material categories, as is the pre-existing SA4B substrate.

With eight usable cutting edges, the sintered inserts offer a competitive price per cutting edge and hence economical machining. The positive geometry ensures a soft, quiet cut as well as good chip flow. Notably, the large radius of the insert’s main cutting edge also promotes a soft cut and,alongside an even distribution of cutting forces, ensuring long tool life.

In terms of machining parameters, the maximum cutting depth is 1 mm (DAH82) and 1.5 mm (DAH84). The DAH82 variant is available as an end mill and as a screw-in milling cutter in the following diameters: 20 (z = 2), 25 (z = 3), 32 (z = 4), 35 (z = 4) and 40 mm (z = 5), where z denotes the number of inserts. As a shell mill, it is available in diameters of 40 (z = 5), 42 (z = 5) and 50 mm (z = 6).

For diameters of 50 mm and more, the larger DAH84 system is first choice. The variants are available only as shell mills in the following diameters: 50 (z = 4), 52 (z = 4), 63 (z = 5), 66 (z = 5), 80 (z = 6), 85 (z = 6), 100 (z = 7) and 125 mm (z = 8).
