Tungaloy is expanding its ISO-EcoTurn series – the economical turning insert and holder system – 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”). Typically, when an insert is downsized, the thickness of the insert is reduced as well. However, ISO-EcoTurn inserts preserve the thickness of standard inserts in order to maintain 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 VNMG 2.33 (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 ø1.25″ (ø32 mm), versus a conventional VNMG 33 (VNMG1604) insert whose minimum ID turn-able is ø1.45″ (ø37 mm). The inserts are available in: CVD grade T9100 for turning steel; CVD grade T6100 and 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 connectors. 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.
- A comprehensive tooling solution is now possible with the 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.
