ISO-EcoTurn – the downsized insert series for reduced tooling costs is expanding to include VNMG inserts and holders

ISO-EcoTurn inserts, while downsized for tool economy, incorporate the identical chipbreaker geometry and thickness of regular-sized inserts to maintain the same cutting performance at a depth of cut up to 3 mm (0.12”). In conventional wisdom, when an insert is downsized the thickness of the insert is reduced as well. ISO-EcoTurn inserts, however, preserve the thickness of standard inserts in order to maintain the fracture resistance.

Thanks to reduced volume per insert, ISO-EcoTurn decreases cost per insert on a production line without compromising insert performance.

The new VNMG inserts and holders complement the existing ISO-EcoTurn series, offering a comprehensive ECO-tooling solution to the turning market. A VNMG1204 insert, among other new insert lines, is not only economical due to its reduced volume but also enables an ID turning as small as ø32 mm, versus a conventional VNMG1604 insert whose minimum ID turn-able is ø37 mm. The inserts are available in: a CVD grade T9100 for turning steel; a CVD grade T6100 and a PVD grade AH600, both for turning stainless steel; along with two cermet grades, NS9530 and GT9530. Chipbreakers for the new inserts include TSF for finishing steel, TM for semi-finishing steel, SS for finishing stainless steel, and SM for semi-finishing stainless steel. The new addition offers holders for OD and ID turnings, as well as holders with TungCap adaptations. TungTurn-Jet system is also available with holders for OD turning and with TungCap interface, which enhances swarf control and tool life through jet streaming coolant supply.

Features

• A comprehensive tooling solution is now possible with this addition of VNMG inserts to the existing lines of CNMG, DNMG, TNMG, WNMG, completing the ISO insert line up.
• Small size inserts with no compromise in performance, providing an economical benefit regarding cost per insert and an ecological advantage to conserve the limited tungsten natural resource.

Tungaloy Corporation is adding a positive insert line to its existing FW & SW turning wiper insert range, allowing for feed rates and surface finish to dramatically improve in general turning operations.

Surface finish quality is directly influenced by feed rate and insert nose radius: the higher the feed rate, the rougher the surface generated by the edge of a given nose radius. In a conventional tactic, the feed rate is decreased to get a better surface quality. Tungaloy’s FW & SW wiper series have changed this through the effect of their uniquely developed cutting edges which allow the feed rate to be increased without deteriorating the surface finish quality. Wiper inserts allow running at up to double the recommended feed rate of a normal insert while still providing a surface quality a double that of a normal insert.

The new line of positive inserts incorporates SW chipbreakers, which will improve chip control in finishing and semi-finishing ID turning operations. This addition will complement the existing negative insert range in the FW & SW wiper series to cover wider range of applications to facilitate customers’ productivity increases.

The new positive inserts are available in T9100, a CVD grade for steel turning and NS9530, a cermet grade for thermal shock resistance, covering a great variety of workpiece materials.

Tungaloy Corporation is expanding its DuoJustCut line to include threading inserts and round shank holders to further its position in small-part machining industries.

Tungaloy Corporation is introducing an expansion to the TungTurn-Jet line, the turning tool system with the high-pressure coolant capability – a perfect tool line for achieving Accelerated Machining.

Until now coolant was simply applied by flooding the cutting area, but often was the case that chips generated during machining intruded the coolant flow, preventing it from reaching the exact spot where needed. Tungaloy’s TungTurn-Jet’s high-pressure, double jet coolant system delivers jets of coolant to the optimum position close to the cutting edge and increases productivity by forming short chips in machining difficult-to-cut materials like heat-resistant super alloys. Tool life is also extended using the second coolant jet from the frontal hole to the cutting point to prevent flank wear on the insert.
Even using normal coolant pressure and existing equipment, TungTurn-Jet improves tool life, and benefits can be enjoyed for stainless and alloy steels as well as heat-resistant super alloys in aerospace as well as automotive and general engineering industries.

This expansion also adds new lines to the ISO-EcoTurn range to further expand its turning capability in a multitude of industries.

Features:

• High pressure coolant jet improves chip control and productivity by forming small chips in machining difficult materials like heat-resistant super alloys.
• Coolant jet is delivered to the optimum position close to the cutting edge, dramatically improving chip evacuation and tool life.

Tungaloy Corporation further expands the industry’s leading head-exchangeable gundrill line, DeepTriDrill with options down to a diameter range of 14-15.9 mm.

Deep hole drilling is a challenging operation and often creates a bottleneck in holemaking shops around the globe. The brazed gundrill or solid twist drill are staple tools in such operations. A typical brazed gundrill has a single-point, non-coated carbide tip. Due to these properties, high parameter drilling has not been attainable. The solid twist drill is suitable/better for high feed drilling; however, curved holes and chip clogging are common setbacks with this type of tool. These traditional deep hole drills come inseparable from reconditioning and inventory management, which incur significant extra costs for every deep drilling shop.

DeepTriDrill features one insert and two guide-pads oriented in an optimized position on the drill head. This achieves tight tolerances with circularity and straightness as well as an excellent surface finish, which a brazed gundrill could traditionally attain. The insert incorporates chipsplitters on the chipbreaker geometry, which shatter chips into smaller pieces to facilitate the evacuation and reduce the cutting force, enabling a higher feed rate than traditional gundrills. The coated insert and guide-pads also allows DeepTriDrill to higher cutting speeds, which have been difficult to reach with brazed gundrills.

DeepTriDrill not only increases machining performance but also facilitates inventory management thanks to its indexable system. This small diameter range expansion complements DeepTriDrill, further enhancing its product positioning in the deep hole drilling market for high productivity and economy.

Features:

• BTA drilling technology for excellent surface finish and tight tolerances with circularity and straightness
• Allows 1.5-3 times higher feed rates than that of a brazed gundrill
• Economical three-cornered insert and double-sided guide pad
• Chipsplitters on the chipbreaker geometry for optimized chip evacuation
• Service free: no reconditioning or tool inventory management required
• Two drill body types available: MCTR for use in machining center or lathe; and TRLG for use in dedicated gundrill machine
