Walter AG Presents New Grades For ISO K And ISO H Materials

Walter AG Presents New Grades For ISO K And ISO H Materials

With the WBK20 and WBK30 CBN grades, Walter is launching two new indexable inserts for turning ISO H and ISO K materials: WBK20 (grain size diameter 3.0 μm) for finishing cast iron; WBK30 (grain size diameter 10.0 μm) for high metal removal rates in ISO H and when finishing with a heavily interrupted cut. Both CBN grades are made from a substrate with a high CBN content and are also suitable for roughing and finishing sintered steel.

The WBK20 indexable inserts are “tipped”. The “CBN tip” is applied to the corners of the insert with high tensile strength by means of vacuum soldering. The WBK30 grade is made from a solid CBN substrate and allows for higher cutting speeds and therefore a higher productivity in cast iron than indexable inserts made from carbide.

In addition to the high-precision manufacturing, a strong microgeometry on the cutting edge also contributes to the high quality, productivity and process reliability of the turning insert. This microgeometry is always matched to the respective application. Walter offers the new WBK20 and WBK30 CBN grades in all of the most popular ISO sizes and radii and thereby completes its extensive CBN turning range. These grades are particularly beneficial for users from the automotive industry, general mechanical engineering and the energy industry.

Kennametal Introduces KCS10B For Superalloy Applications Used In Aerospace

Kennametal Introduces KCS10B For Superalloy Applications Used In Aerospace

Kennametal has introduced its newest turning grade, KCS10B, for nickel, cobalt and iron-based superalloys used in aerospace and other high temperature applications.

KCS10B, which features a revolutionary coating applied to an ultra-fine grain carbide substrate for superior layer adhesion, delivers up to 50 percent greater tool life, more predictable processes, and improved productivity when working with difficult to machine superalloys. KCS10B overcomes the most common challenges encountered in turning superalloys—cratering and depth-of-cut notching—two wear modes that often lead to unexpected and even catastrophic tool failure.

Special Sputtering

Rather than the light rain of droplets that fall on cutting tools during traditional PVD coating processes, Kennametal’s High-Power Impulse Magnetron Sputtering (High-PIMS) technology generates a fine mist of AlTiN, building a series of “extremely thin, smooth, and wear-resistant layers.”

Beating wear

Metals such as Inconel 718 and Stellite 31 are notorious for causing rapid wear and unpredictable tool life, KCS10B is proven to reduce DOC notching and extend tool life from three minutes to upwards of five minutes in roughing operations. Tool life in finishing operations fares even better, with visible cratering and subsequent tool failure often delayed by a factor of two or three compared to competitive brands.

Tungaloy Revs Up Turning Efficiency In Heat-Resistant Superalloys With New Ceramic Insert Grades

Tungaloy Revs Up Turning Efficiency in Heat-Resistant Superalloys With New Ceramic Insert Grades

Tungaloy has unveiled two new ceramic insert grades: TS200 and TS300 that are developed for performing high-speed, high-efficiency turning operations of heat-resistant superalloys. The company has also introduced dedicated turning toolholders with a T-style insert clamp that are designed to securely hold the ceramic inserts to withstand demanding operations.

TS200 and TS300 are both SiAlON ceramic grades that are designed to perform high-speed turning operations of HRSAs common in aerospace, power generation and oil and gas industries. The TS200 is suitable for finishing processes; while the TS300 is ideal for removing oxide layer and other roughing operations.

The dedicated turning toolholders feature a unique T-style insert clamp with a carbide plate attached. This plate holds the ceramic insert securely in place in the seat to provide process security during demanding operations.

Sandvik Coromant Extends Advanced Insert Grades To Additional Milling Concepts

Sandvik Coromant Extends Advanced Insert Grades To Additional Milling Concepts

Following the successful introduction of its GC4330 and GC4340 steel milling grades, Sandvik Coromant is now extending the range of application for these advanced insert grades to additional milling concepts. The grades are now available for selection with the CoroMill 300 round-insert face and profile mill; the CoroMill 245 multi-purpose face milling cutter; and the CoroMill QD cutter, which is optimized for deep and narrow grooving and parting off.

GC4330 and GC4340, which feature a specially developed substrate, Inveio coating and enhanced post-treatment technology, allow users to enjoy substantially increased tool life and process security. The extension of these grades to additional Sandvik Coromant milling concepts brings their advantages to even more machine shops looking to optimize the milling of steel workpieces.

Among the many design attributes of GC4330 and GC4340 is the optimized Inveio coating. Inveio is the technical breakthrough of uni-directional crystal orientation in the alumina coating layer that gives inserts a new level of wear resistance and tool life. Furthermore, the substrate of the grades delivers highly controlled grain size distribution for more reliable and predictable insert behaviour.

GC4330 is a medium-hard grade for roughing to semi-finish face milling, while the GC4340 grade is for rough shoulder milling and groove milling. Both grades are also extended to the CoroMill 360 heavy-duty face mill, CoroMill 419 high-feed mill, and LPMH-PM plunge-cutter inserts. In addition, GC4330 is available for the CoroMill 365 high-security face mill, while GC4340 can be applied to the CoroMill 216 ball-nose end mill and CoroMill 415 small-diameter high-feed face mill.

Seco: Insert Grades

Seco: Insert Grades

Seco has released three insert grades TP2501, TP1501 and TP0501, for steel turning with Duratomic coating technology to provide improved toughness, heat resistance and chemical inertness. This lengthens tool life and offers the potential for higher cutting speeds.

TP2501 suits a variety of workpiece material requirements and unpredictable working conditions with its highly secure edge toughness behaviour. TP1501 is well-balanced and suits applications requiring high wear resistance in low-alloy steel workpieces. TP0501 provides high wear resistance and cutting speeds, and suits stable machining conditions and situations requiring high output.

The TP grades also feature used-edge detection that do not impact tool performance, yet allows machinists to quickly and accurately identify used edges with the naked eye.
