Walter is launching a new range of thread milling tools called Thrill·tec that combines the machining steps of core-hole drilling and threading in a single tool and operation. This is also true of the TC645 Supreme circular drill/thread mill, which additionally produces a chamfer at the thread entry.

Combining work steps improves productivity and makes this three-in-one thread milling cutter ideal for mass and small series production alike. High-volume producers can benefit from longer tool life and shorter machining times. Furthermore, the ability to multi-task results in significantly less machine downtime for tool changeovers. The TC645 Supreme pays dividends for small-scale manufacturers because they only have to use one tool, reducing changeovers and tool positions in the machine.

The left-hand cutting thread milling tool is suitable for multi-tasking operations, credit largely to the milling geometry on its face and the internal coolant supply. According to Walter, the tool optimises chip removal, even at high cutting speeds, and demonstrates high feed per tooth. As a result, the tool is suitable for blind-hole and through-hole threads in dimensions of 2 or 2.5xD. The universal thread milling cutter is for use on all ISO materials from P, M, K, N and S up to 48 HRc, due in large part to Walter’s WB10TJ grade coating.

In addition to high process reliability and universal operation, the main advantage of the TC645 Supreme is its cost efficiency. Faster machining and reduced indexing times keep the cost per thread relatively low. Walter is offering the TC645 Supreme in dimensions of M4 to M12, UNC8 to UNC½ and G1/16 to G¼. Additional variants will become available as the line expands.

Guhring premiered a host of new cutting tool innovations at the recent MACH exhibition in Birmingham, UK. For instance, the company gave a show debut to its RT100 InoxPro range of solid-carbide drills for stainless steel and titanium alloys. When machining these challenging materials, tool wear can be a formidable opponent to productivity and performance. According to Guhring, the new RT100 InoxPro overcomes these challenges with new geometry that optimises chip formation. This design combines with an ultra-smooth Perrox coating that enhances wear protection and an optimised carbide substrate that delivers a balance of hardness and toughness.

Available in 3xD, 5xD and 7xD variants and from 3 to 20 mm diameter in 0.1 mm increments, the company says this through-coolant series will improve feed rates and tool life by more than 50% while enhancing process control and chip evacuation.

The milling portfolio from Guhring continues to rapidly expand. Since the previous MACH show in 2022, the manufacturer has added a wealth of innovations, including the new SkyLiner series of end mills for the rough and finish-machining of aluminium and non-ferrous materials. Especially suited to pocketing and wall applications featuring thin-wall sections with depths up to 3xD, the new Alu RF100 SkyLiner F delivers smooth surface finishes at high feed rates, reports Guhring.

This three-flute tool is offered in diameters from 6 to 20 mm with axial through-coolant ducts, a 0.2 mm corner radius and a variable helix that makes the range suitable for finish milling. Accompanying the Alu RF100 SkyLiner F at MACH was the Alu RF100 SkyLiner R for rough machining in aluminium.

Mapal says that its new NeoMill-Alu-QBig indexable insert milling cutter stands for top performance in the high-volume milling of aluminium. The tool manufacturer thus offers an economical solution for use on high-performance machines, such as those found primarily in the aerospace industry.

With its NeoMill-Alu-QBig solid-carbide roughing cutter for aluminium, Mapal says that machine shops can achieve a material removal rate of more than 18 l/min on high-performance machine tools. At the same time, it is of course also possible to use the high-volume milling cutter on less powerful machines. The tool manufacturer is thus taking into account the fact that aircraft parts often see manufacture on machines with spindle outputs between 40 and 80 kW, for which there was previously no suitable milling cutter in the company’s portfolio.

In order to maximise the material removal rate, Mapal designed the new aluminium volume milling cutter for use at spindle speeds of up to 35,000 rpm (with a diameter of 50 mm). For a tight fit, despite high centrifugal forces, screws with high tensile strength hold the indexable inserts firmly in the prismatic seat. In addition, countersinks on the indexable insert ensure weight savings. The tool body features a fine balancing system. Four threaded bores enable precise adjustment in order to protect the machine spindle at high speeds and achieve the smoothest possible surface finishes.

In addition, Mapal placed focus on low cutting forces and highly precise indexable inserts. High chip volumes with very high achievable surface finishes of Ra 0.8 µm and Rz 4.0 µm for rough and fine machining are thus achievable with the tool.

Seco Nanojet solid-carbide reamers enhance chip control with an innovative through-coolant outlet for optimal chip evacuation. This design eliminates costly scrapped parts, jamming and edge damage to increase safety, part quality and tool life.
 

Critical reaming operations require stable, secure, predictable tools. On blind and through-bores, Seco Nanojet solid-carbide Reamers extend the performance of the company’s Nanofix products with through-coolant outlets that stop chip jamming and enhance application stability. Seco says that the proprietary design of these new tools delivers a powerful, precise stream of lubrication directly to the cut zone for optimal chip evacuation and tool life. Along with production stability, shops can rely on Seco Nanojet to maintain cutting speed and part quality, reports the company.

This versatile range of multi-flute reamers comes in eight grades and more than 10 geometries, along with custom sizes and tolerances. The tools work with any precision toolholder. They hold tolerances from 10-15 µm and produce surface finishes from Ra 0.2 µm to Ra 1.2 µm. Seco inspects each Nanojet solid-carbide reamer and documents its measured diameter for consistent performance.

Many industries, including general engineering, automotive and aerospace rely on secure, reliable reaming to avoid costly scrap. According to Jean-Bernard Hantin, product manager at Seco, manufacturers realise that poorly manufactured or incorrectly specified reamers can jeopardise high-value parts. “Nanojet solid-carbide reamers provide cost-efficient performance with much needed quality and stability,” he says.

Seco Nanojet solid-carbide reamers are available in stock and custom diameters down to 1.461 mm. Through the online Seco MyDesign tool configurator, machine shops can obtain custom tools with the stability, reliability and availability of commodity products.
