Multifunctional DHC INOX and DHC SLOT solid carbide cutters The new DHC INOX from FETTE has four cutting edges, and was specially developed for cutting stainless steel, titanium, nickel-based alloys and short-chipping aluminum. The high number of teeth makes it particularly suitable for high tooth feed when trimming. DHC stands for Different Helix Cutter: different spiral angles of 41° and 44° on the sequential cutting edges, combined with large rake angles, also reduce force magnitudes and vibrations, allowing an increased volume removal rate. The short version of the cutter can increase the feed rate by up to another 40%, and does this at the same time as achieving finished quality! The newly developed DHC SLOT from FETTE has three cutting edges. It is ideally suited to slotting work thanks to its large chip spaces and its extremely good chip removal. Each cutting edge has a different helix angle (33°/35°/37°) combined with a further increase in the rake angles. These tools therefore satisfy the high performance demands made of the DHC cutters. And this applies to the full spectrum of machined materials. In summary, the advantages of using the new DHC specialized cutting tools can be described as follows: - Economical machining of stainless steel, titanium and nickelbased alloys, short-chipping aluminum - Finished quality achieved even when roughing - Multifunctionality: one working pass is saved - Process reliability with significantly increased tool lives - Increased volume removal rate - Shortening of production times - Reduction of production costs
The new Flatball solid carbide copying end mill avoids zero speed at the centre The new Flatball from FETTE is a particularly valuable addition to the HSCline family of end mills. Its particular geometrical feature is the implementation of the face cutting edges. These consist of two semicircles, and are arranged in such a way that the smallest cutting circle diameter is always 2 mm. This avoids the cutting centre working with the awkward zero speed. This is helpful for minimizing wear at the cutting center whilst at the same time reducing heat dissipation, so increasing tool life and raising process reliability. What is more, in contrast to conventional ball nose copying mills, larger stroke intervals can be achieved with the same surface quality when contour milling, thereby significantly reducing cutting times. Another advantage of using these mills is the reduction in residual material in the floor/wall region that is a consequence of the smaller corner radius in comparison with conventional ball nose copying mills. This new Flatball, which is offered in a range of diameters from 6 - 12 mm, successfully takes an important development step in the direction of reducing costs in the field of its main application, tool and mould construction.
µ-Jet and Air-Jet indexable inserts ? dynamic precision in ideal time The new µ-Jet generation of indexable inserts from KIENINGER unites the maximum possible material removal performance with top precision when roughing, machining remaining material and semifinishing in die and mould making. The improved chip curler geometry significantly increases the rate of chip removal. The tool life is also extended, which saves hard cash. Very smooth running permits reliable working. The pressed centre of the cutting edge guarantees outstanding chip removal even at high feed rates. The advantages of the new µ-Jet indexable inserts are of full benefit to all HSC machines ? not just to the latest models. µ-Jet indexable inserts are also available with integrated air cooling under the name of Air-Jet. The cooling channels here are directly integrated into the indexable insert, so providing the highest possible protection for the cutting edge.

LMT-Fette introduces new carbide insert technology to the forming tap market with its HPF Carbide Insertable Forming Tap - an industry first. The HPF is the only tap to feature a replaceable carbide insert on a steel body. The carbide insert allows for cutting speeds 2-3 times higher than that of an HSS form tap, at a fraction of the price of a solid carbide tap. Furthermore, the excellent wear resistance characteristics of the carbide insert lead to increased tool life – up to 30x. This results in a lower cost per tapped hole. The HPF features a hardened steel shank, designed with four drive tangs that help to handle the torque present in a tapping operation. Each steel shank is made to DIN specifications for added reach capability. The carbide inserts are available with or without “lube grooves” for optimized tool life, in through or blind holes, and are available in UNF sizes of 3/8-24 to 3/4-16 and metric fine sizes from M10 x 1.0 to M18 x 1.5. The HPF carbide inserts are TiCN Plus coated for use with a range of materials. The HPF is capable of tapping all ductile materials up to 32 Rc. The pure hardness of the carbide insert enables the HPF to form work piece materials considered too hard for HSS or powdered metal form taps. These taps can be run with high tensile strength materials, such as aluminum, steel or stainless steel. LMT-Fette’s HPF is designed for high production tapping applications including automotive, aerospace and general machining. The HPF demonstrates the innovative technology that defines LMT Fette as the market leader in both O.D. and I.D. thread forming products. LMT-Fette blends precision European engineering with application expertise, resulting in advanced metalworking solutions that increase up time, productivity and product quality. LMT-Fette will continue to be on the forefront of metalworking technology with new products in milling, turning, tapping, thread rolling and gear cutting.

New center provides engineering, service and tool management support / High-speed production facility at LMT company Onsrud Today the Leitz Metalworking Technology (LMT) Group celebrated the opening of their Automotive Support Center (ASC) for the North American Automotive industry in Auburn Hills/Detroit. The Automotive Support Center is a central element of the growth strategy with which the LMT Group aims to substantially increase sales in the North American market over the next few years. Attendees participating in this important event included dignitaries from the City of Auburn Hills, Oakland County, and the State of Michigan. An appearance was made by Auburn Hills Mayor Mari Harvey-Edwards, and guest speakers included Oakland County Executive Mr. L. Brooks Patterson, Vice President of Business Development for the State of Michigan, Mr. Sandy Ring, and the Honorary Consul for the Republic of Germany, Mr. Fred Hoffman. The range of services provided by the Automotive Support Center has been specially tailored to the needs of the automotive and machine tool industry. As a general partner, LMT offers these customers its entire international know-how, not only for tool development, installation and presetting, but also for tool refurbishment and tool management. As a result, LMT supports its customers during their running production as well as during the run off phase for new investments. The Automotive Support Center concentrates the competencies of the LMT Group in cutting materials and precision tools. The technology available includes all the equipment needed for presetting as well as various machine tools for test and demonstration purposes. Connection to the internal broadband network gives the Automotive Support Center direct access to the expertise of other LMT companies and the Engineering Center in Oberkochen. Dieter Brucklacher, Executive Chairman of the Leitz Group, considers this form of networking a major competitive advantage for LMT: “The two most important trends we are currently observing in the automotive industry are globalization and localization. Globalization is compelling businesses to build networks – not only internally, but also externally – and to form partnerships. Localization, on the other hand, means that businesses have to be in a position to support their partners locally on the spot. That is precisely what we are doing – with the Automotive Support Center – by offering our customers in Detroit a unique platform for the rapid joint development of complete integrated tooling solutions for the production of complex components.” In addition to technical support, the Automotive Support Center also offers solutions in the areas of service and tool management. A complete regrinding unit is available in Auburn Hills for tool refurbishment and modifications. A separate production and service unit has been set up at Onsrud, the North American LMT production company. In addition to its main production activity, especially in the area of tooling for lightweight composite materials, Onsrud is now producing hobs in order to respond quickly to customer production peaks and develop prototype tools. Further, Onsrud is now producing special solid carbide tools for the Automotive industry. Local production of this kind is a decisive factor for American companies when awarding contracts. Dr. Hans F Grandin, President of LMT North America, is all too aware of that: “Besides comprehensive support, our customers are primarily concerned about two things: quality and availability. Generally, when it comes to quality, products from the LMT Group have a head start. Thanks to the high-speed production facility at Onsrud, we can now provide this quality with short delivery times.” The establishment of a special training center at the Automotive Support Center is another expression of this customer focus. The center is equipped with state-of-the-art training technology and linked to the LMT network. The range of training courses is tailored to employees of automotive and machine-tool manufacturers that want to learn about the latest trends in cutting technology. Practical training is carried out on the test and demonstration installations. Management is convinced the Group will achieve its ambitious goals. “We at LMT aspire to make the biggest contribution to improvements in our customers’ performance,” stresses Michael Heinrich, CEO of the LMT Group. “As a unique association of cutting technology specialists, we do not only take responsibility for project management, but also for every step of the tool production process itself. We are confident that American customers will appreciate that kind of service.” With the new Automotive Support Center in Detroit, LMT is offering its customers another central point of contact. As a result, partners in the world’s most important automotive market can draw on the entire expertise of the companies within the LMT Group. In turn, these centers will give LMT Group companies joint access to customers in key markets. The establishment of additional Automotive Support Centers with comparable services is thus planned above all in the growth markets of China, India and Brazil.

The success of the Point Blank, the industry’s first coolant-fed turning holder, has prompted LMT-Fette to expand on to its popular line, and widen the scope of application possibilities. The Point Blank is now available in three new configurations for external turning on swiss style machines, internal boring and heavy-duty in negative style turning holders for applications in optimizing insert life and chip control. The Point Blank is the industry’s first innovative modification to turning holders in over two decades. Point Blank Coolant-Fed O.D. Turning Holders finally eliminate the problems associated with inconsistent coolant, and they dramatically increase tool life. The Point Blank’s patented holder design with top plate, or coolant nozzle design, directs coolant right where it needs to be - on the cutting edge. In addition, the orifice size on the Point Blank top plate maximizes coolant velocity. This leads to unsurpassed chip evacuation, increased tool life and improved surface finishes, even at higher cutting speeds. The Point Blank holders now include a full range of sizes including 3/8", 1/2", 3/4",1", and 1 1/4" square shank tools, in right and left hand, for all common turning inserts, including CNMG, WNMG, VNMG and DNMG styles. Boring Bars are now available in 1”- 1 1/2” sizes, available in negative 80° geometry. Existing machine programs need no altering, as Point Blank holders are made to ANSI specifications. Point Blank holders include industry-standard hardware. This makes the conversion to Point Blank simple and cost-effective. The Point Blank is suitable for all roughing and finishing applications. LMT-Fette blends precision engineering with application expertise, resulting in advanced metalworking solutions that increase uptime, productivity and product quality.

Lathe Toolholders For Turning Away
Think 'unattended machining,' and the image in your mind is probably complex - that is, some machining process that relies on automation more than the typical machining process does. But does going unattended have to involve this complexity? Instead of requiring automation, allowing the operator to step away from the machine tool might just be a matter of addressing the sources of worry that keep that operator engaged.
Rolling Threads Has Advantages
With macros and canned cycles resident in the CNC on most contemporary turning centers, single point turning of OD threads can seem like almost a default process decision. However, for numerous applications, OD thread rolling has inherent advantages as an alternative to cutting threads.
