Seco Tools has expanded its range of tapping solutions with the launch of a new thread-cutting and forming taps product line.

The versatile newrange encompasses three performance levels that allow manufacturers to cost-effectively match the right tap to their particular application. According to Seco, the combination of superior base materials, advanced coatings and special edge preparations mean that thetaps generate precision threads while providing effective chip evacuation, shorter set-up times and longer tool life.

“With the launch of the new line of thread-cutting and forming taps, we now offer customers a one-stop solution for high-quality taps at competitive prices,” says Radoslaw Zdanowski, global product manager at Seco Tools. “In addition to this affordability, we maintain the same high quality in these taps that our customers have come to expect from Seco.”

The three performance levels encompass the product designations of T32 and T34 in thread-cutting taps and T33 in forming taps. At the base level are universal general-purpose type taps. The second T34 mid-level range consists of higher performance taps that work well in a variety of workpiece materials, making them especially suitable for high-mix/low-volume production environments with constantly changing parts and materials. The top performance level comprises material-specific thread-cutting and forming taps, such as those optimised for steel or other advanced materials.

The main benefits of matching the right tap to the application include extended tool life that is consistent and predictable to reduce the risk of unexpected tap breakage and scrapping parts after hours of machining have been invested. Additionally, a range of tap performance levels ensures manufacturers only pay for the level of tap performance they actually need.

A new-generation turning grade is now available that its manufacturer Dormer Pramet says offers one of the highest levels of productivity and versatility available on the the market today. The company says that its T9415 is the most advanced MT-CVD coated turning grade it has launched in almost 10 years, bringing greater stability and performance in a variety of cutting conditions.

This fourth-generation Pramet grade covers a broad application range, replacing the previous T9310 and T9315. In addition, the new grade partly overlaps with the company’s T9325 grade, giving T9415 one of the widest range of applications in steel turning.

Featuring a 30% thicker coating than the previous generation, the Pramet T9415 improves tool durability by increasing resistance to wear and offers higher productivity by allowing for higher cutting speeds. Additionally, a new post-treatment process improves toughness and reliability of the cutting edge, especially in interrupted cuts and unstable conditions. The T9415 is also suitable for high cutting speeds.

Notably, grinding of the insert seating area improves stability and enhances heat transfer away from the cutting edge. This capability further helps to improve tool life, reducing the plastic wear on the cutting zones. Also, a gold TiN coating allows operators to detect wear along the flank of the inserts.

Using the latest technologies, Pramet T9415 inserts have optimised cutting-edge geometry that reduces cutting forces and enhances performance. Along with saving energy, the inserts themselves are manufactured using the latest production technologies, which supports a more sustainable and environmentally friendly offer.

A new, high-feed milling system forfinishing non-ferrous metals and plastics is now available from Horn Cutting Tools. Designated DTM 1710, the tool system employs inserts with PCD cutting edges brazed onto cassettes that allow fine axial tuning to micron precision via adjusting screws on the tool carrier. The PCD substrate is laser-cut to achieve high surface quality during the finishing process. Axial run-out is set by Horn engineers before tool delivery.

Compared with other tools of this type on the market, Horn says its milling system offers a higher number of cutting edges for any given size. The tools are available in the diameters 50 mm (z = 10), 63 mm (z = 14), 80 mm (z = 18), 100 mm (z = 24) and 125 mm (z = 30), with z representing the number of inserts. All variants have internal coolant supply.

To achieve a high-quality machined finish on the workpiece and enable use at high speeds, the tool must be in balance with the tool holder, for which purpose balancing holes are available around the cutter body. Furthermore,the combination of machine design, guideways, spindle and work-holding system, as well as the milling tool, have a decisive influence on the result.

The aluminium alloy milling body is lightweight, minimising centrifugal force and hence prolonging spindle life. For long-term protection against abrasion from chips, the cutter body is surface treated.The Horn high-performance PCD cutting material comprises a mixture of different diamond grain sizes. As the proportion of diamond by volume increases, so does the effective hardness, toughness and cutting edge quality. For the DTM 1710 milling system, Horn offers two different PCD substrates to suit the workpiece material.

Kennametal has introduced a higher performance turning grade with an advanced coating technology. KCP25C with KENGold is now the company’s first-choice offer for metal-cutting inserts with improved wear and higher metal removal rates in steelturning applications.

“Our high performance KCP25C grade inserts with KENGold coating technology sets a new standard for machinists working across a variety of steel turning applications,” saysvice president of global product management Scott Etling. “This gold standard turning insert delivers a one-two performance punch of higher metal removal rates and improved wear resistance, meaning our customers can machine longer and with greater productivity and efficiency than before. Additionally, the insert’s gold flank makes it easy to visually identify wear, maximise edge use and reduce waste.”

According to Kennametal, KCP25C is the company’s first-choice carbide grade for turning inserts in general purpose applications in a variety of steel materials and delivers consistent, repeatable performance. KENGold is a proprietary, multi-layer coating technology with enhanced pre- and post-coat processes that deliver an effective thermal barrier for greater resistance against crater wear, which is common in these types of machining applications.

KCP25C with KENGold is an example of how Kennametal’s global modernisation investments are enabling the company to innovate higher-performing products for customers. Kennametal uses next-generation CVD technology to produce the coating while advanced pressing and surface treatment technologies deliver tighter tolerance levels than ever before, resulting in a more consistent, reliable tool life.

Kennametal is releasing KCP25C with KENGold in the most common insert shapes and styles: C, D, S, T, V and W. Longer term, the company plans to expand on KCP25C with additional turning insert shapes and styles—all featuring the KENGold coating technology.
