Jetstream Tooling Integrated (JETI) toolholders from Seco Tools bring the benefits of high-pressure coolant (HPC) to round, positive turning inserts for profiling and pocketing in difficult-to-cut materials. JETI toolholders eliminate hoses and spare parts associated with HPC, while 3D-printed coolant clamps provide internal coolant channels for cutting zone cooling and chip control. The precision delivery of HPC by the tool holder’s internal coolant channels allows increased cutting speeds and feeds for shorter part cycle times.
 
“JETI toolholders permits shops to step up their pocket machining operations,” says Seco product manager Frederik Samuelsson. “Combining the benefits of HPC, round turning inserts and favourable dynamic turning methods ensures manufacturers can attain optimal cutting speeds and feed rates while achieving higher metal removal rates for increased productivity. This combination of technologies also optimises chip control and evacuation to improve tool life, while increasing turning process reliability and reducing tooling costs per part.”

JETI toolholders use a single-screw design on the coolant clamp for fast insert indexing and changes. An easy plug-and-play solution, without hoses, integrates effortlessly to avoid long set-up times and maximise machine utilisation. Jetstream Tooling is available for 72 holders for maximum application coverage. Square shank sizes are available in metric 2020, 2525 and 3232, and imperial 12, 16 and 20, with Seco-Capto sizes C3, C4, C5, C6 and C8.

In addition to simplifying set-up times for faster job changeovers, JETI toolholders with a Seco-Capto connection come with a pre-drilled hole to install a Balluff chip. With this feature, shops can incorporate the tool holders into an RFID system to manage data gathering and transfer without manual entry.

At the AMB 2024 exhibition in Germany toward the end of last year, Hainbuch won the exhibition’s award in the precision tools category for its Maxxos T212 mandrel. The expert jury presented the mandrel with the trophy from six nominated products.

Increasing process stability is crucial for optimising production. Hainbuch offers an innovative solution with its new Maxxos T212 mandrel. Thanks to the hexagonal pyramid shape, the company says its Maxxos mandrel delivers maximum accuracy and feed rates.

The hexagonal mandrel achieves a significantly higher holding power than the round Mando mandrel, while also enabling up to double the torque transmission and corresponding cutting rates. Hainbuch offers the Maxxos T212 mandrel in 12 sizes for diameters from 8 to 200 mm.

Maxxos T212 mandrels have no draw bolt. They are therefore suitable for workpieces with blind holes and very short clamping lengths without any loss of clamping length. The pull-back effect means they will deliver benefits during the five-sided machining of workpieces on both turning and milling centres.

Thanks to the hexagonal pyramid shape, the segmented clamping bushing with the hexagon socket sits on the clamping pyramid with an absolute positive fit in every clamping position. The resulting vibration damping has a noticeably positive effect on tool life and therefore contributes to sustainability in production. In addition, compared with the previous solution, the bayonet quick-change lock saves time when switching segment clamping bushings during the set-up of different diameters.
