Seco Tools is offering a new family of versatile, highly productive solid-carbide end mills: the JSE510 series. Redesigned to offer more rigidity, chip control and tool life, the company says the new milling cutters achieve the lowest possible costs per metre of machined steel, stainless steel, cast iron, titanium and some aluminiums. The cutters provide high process reliability across a broad application range.

JSE510 cutters offer higher versatility in comparison with the previous version of this product range, not just for general engineering, contract manufacturers and job shops, but those specifically serving the aerospace, medical and automotive industries. Seco’s design for the JSE510 stands up to tough milling applications with a versatile carbide grade, advanced polished SIRA coatings and a strong, sharp cutting edge. To extend tool life further, the tools offer a vibration-damping variable pitch design and an optimised helix.

Seco’s JSE510 family includes 216 tools in four geometries, with two length variants in the three and four-flute version: normal (LV2) and long (LV3). The two-flute JSE512 handles the large chips produced in helical interpolation or peck drilling, keyways and slotting applications, while the three-flute JSE513 offers universal milling performance for ramping, full slotting and side milling. The four-flute JSE514 is for side milling and slotting, as well as dynamic milling. Finally, the ball-nose end-mill geometry of the JSB512 offers the versatility required for finishing operations.

“These cutters offer productivity in less stable machining conditions or when pushed hard to balance productivity and tool life costs,” says Rob Mulders, solid end mills global product manager. “This versatility makes the JSE510 series particularly useful when shops face increased tooling costs because of a greater variety of applications and materials.”

Dormer Pramet has expanded its offer for true 90° shoulder milling in various materials.

With improved cost per edge, the company’s new range of TNGX16 inserts and STN16 cutters feature larger double-sided inserts with six-cutting edges, providing greater depths of cut (up to 10 mm) and higher feed compared with its existing TNGX10 range.

By offering low cutting resistance, the assortment improves the connection between passes, creating high surface quality. This reduction in forces leads to smooth, quiet machining for additional process security.

Positive geometry and through-coolant offer improved chip evacuation across a range of materials, including steels, stainless steels, cast iron and non-ferrous metals.

Dormer Pramet’s TNGX16 assortment is available in radii from 0.4 to 1.6 mm and in a range of grades. Three geometries, F, M and FA, support the insert. F is the first choice for low to medium carbon content steel. A high positive geometry with narrow peripheral land makes F geometry suitable for light to medium machining.

M geometry is for machining carbon steel, stainless steel and cast iron. This positive geometry with medium T-land makes it suitable for light to medium machining.

For use on non-ferrous metals, FA is a high positive geometry with a sharp cutting edge. The polished insert face reduces adhesion to machined material.

Meanwhile, STN16 tool holders provide a higher number of teeth for greater productivity in comparison with the original assortment. The differential pitch offers smooth machining in diameters above 50 mm.

The new MaxiMill 275 milling system from Ceratizit suits the rough machining of high-alloy stainless and refractory steels, materials often found in the manufacture of turbocharger housings and exhaust manifolds. Ceratizit’s MaxiMill 275 face milling system is suitable for processing flat surfaces on these components. The tool is robust in its construction and design, with a maximum number of indexable inserts for efficient machining. Inserts are ground all around to ensure a smooth milling action, high-quality surfaces, long tool life and high efficiency.

The face milling of turbocharger components presents huge challenges for cutting tools due to the demanding nature of the material – often refractory cast steel containing niobium. In addition, the features of turbocharger housings and exhaust manifolds frequently create insecure machining conditions, bringing a requirement for tool stability so that it cuts effectively and achieves the necessary quality.

“Our development team began the process by designing the cutter body to be extremely stable and have low vibration,” says Detlef Erdei, application manager automotive at Ceratizit. “We were then able to optimise the number of cutting edges based on the diameter.”

This work resulted in the largest MaxiMill 275 with 125 mm diameter featuring 18 teeth, while the smaller 63, 80 and 100 mm diameter variants have 7, 10 and 14 teeth respectively.

The Ceratizit development team paid particular attention to the accuracy of the insert seat, which keeps the indexable insert firmly and precisely in place using a wedge clamp.

Ceratizit’s indexable inserts have also been refined thanks to the use of a special cutting material for the highest thermo-mechanical demands. Furthermore, a positive geometry with a 20° rake angle enables the inserts to cut effectively and guarantee a smooth machining action.

Kennametal has introduced its HiPACS drilling and countersinking system for aerospace fastener holes. Designed to drill and chamfer holes in one operation, the high-precision tool meets the aerospace industry’s stringent accuracy requirements, while delivering long tool life when machining composite, titanium and aluminium aircraft skins.

“Most fastener hole tools used today are complex made-to-order tools with long lead-times,” says Georg Roth, product manager at Kennametal. “HiPACS uses standard, off-the-shelf components for quick delivery and low cost per hole, by allowing the drill and chamfer insert to be indexed independently from one another. What’s more, it’s the
only indexable drilling and countersinking system on the market that can hold the aerospace industry’s required fastener hole chamfer tolerances in just one operation.”

Designed to be clamped in a standard hydraulic chuck, the HiPACS modular system consists of three components that are fast and easy to assemble: a reducer sleeve with a built-in high-precision pocket seat which, in conjunction with a standard hydraulic chuck, provides ultra-secure clamping and a runout of no more than 3 µm to increase tool life and hole quality; a PCD countersinking insert that eliminates the need for expensive custom solution step drills, thus reducing manufacturing costs while meeting the industry’s accuracy requirements; and two series of solid-carbide drills – both diamond-coated and PCD-tipped – covering all material combinations found in a typical aerospace assembly. In addition, the straight shanked tools allow for length adjustments in increments of 10 mm.

It is possible to utilise the new HiPACS drilling and countersinking system on all machines typically used for aerospace applications. In less stable conditions, such as robot end effectors, the diamond-coated carbide drills offer long tool life and high hole quality.
