Original Innovative Tool Holders Coming From Iscar Guide The Way In Machining Effectiveness


Iscar's Heliturn system features a unique, double-sided insert with 4 cutting edges for Fast Metal Removal (FMR) turning. The revolutionary Heliturn is a tangentially clamped insert using a unique helical shaped cutting edge, useful for enormous depths of cut and higher than standard feed rate. The LNMX...-HT Heliturn insert is screw-clamped into the SLANR tool holder and held by the TLN ..-HT carbide seat. This seat has ground surfaces on the top and bottom, to ensure perfect contact of the insert with the tool holders. The upper rake face of this insert is mounted level with the top of the tool holder to enable chips to flow across the insert, without being disrupted by clamps or the tool holder body. The 4 curved helical cutting edges assure positive radial rake angles and soft penetration into the material being cut. The reduced forces and smaller loads ensure better tool lifetime, elevated stability and the ability to use very massive depths of cut and larger feeds. The chipformer, manipulates and breaks the chip into rib type curved pieces which can easily be removed from the cutting area. This insert has a frontal clearance angle of 3.7 with a 6 side clearance angle to allow machining to a 90 shoulder. Depths of cut up to .315" and facing depths to .126" at up to .047" IPR are attainable with Heliturn.

When compared to CNMG/M 16... or WNMG/M 13... insert sizes with the similar corner radius, much greater tool life can be predictable when using the LNMX 1506..-HT insert. Iscar has recently added a smaller size to the Heliturn family - the LNMX 1104..R/L-HT insert and tool holder for the common application range of up to .197" depth of cut. The new insert features all of the benefits of the larger insert. This enhances the economical advantage in the medium machining application range. When compared to CNMG/M 43. 12... or WNMG/M 43. 08... insert sizes with the same corner radius, a significantly better tool life can be foreseen. The inserts are accessible in .031, .047 and .063" tool nose radii. Heliturn inserts are available in the most exceptional carbide grades: IC9025, IC3028 , IC428, IC907, and IC908.

The external tool holders are available in 1, 1.25 and 1.5" shank sizes. Boring bars are presented in 1, 1.25 1.5 and 2" bar sizes. Also obtainable are exchangeable heads. These tool holders have Iscar's unique Hard Touch coating, which extends holder life and hinders corrosion. As a result of the positioning of this insert, machining next to the tailstock is reasonable.

The high positive rake angle of these tools allows 10-15% less power usage than normal tool holders at the same parameters.

By using Iscar's Heliturn tools, massive cost savings and profitability in lathe procedures is guaranteed.

A Brand new 80 Degree Rhombic Insert with high helical cutting edge for high metal removal rates Iscar is announcing the CNMX 1207..-HTW insert family. The revolutionary insert has a very positive radial, helical cutting edge and a positive rake angle; a incorporation which substantially decreases the cutting forces. The insert's corner has a wiper configuration which provides high surface finish even at high feed conditions, which in abundant occasions can eliminate a finishing cut. The corner angle is 88 degrees which provides increased strength. The CNMX inserts were built for heavy machining applications. Their special design ensures dependable, fast metal removal when using 80 degree rhombic inserts. They can be mounted on any standard tool holder that carries typical CNMG inserts, but the seat has to be replaced with a special seat: TCH 4. Iscar's R-clamp tool holders are highly advocated for heavy machining applications.
