Completely New Innovative Tool Holders Coming From Iscar Head The Way In Machining Capacity

Iscar's Heliturn system features a unique, double-sided insert with 4 cutting edges for Fast Metal Removal (FMR) turning. The brand new Heliturn is a tangentially clamped insert utilizing a unique helical shaped cutting edge, useful for immense depths of cut and higher than common feed rate. The LNMX...-HT Heliturn insert is screw-clamped into the SLANR tool holder and fortified 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 the insert is mounted level with the top of the tool holder to enable chips to flow across the insert, without being afflicted by clamps or the tool holder body. The 4 curved helical cutting edges establish positive radial rake angles and soft penetration into the material being cut. The decreased forces and smaller loads ensure better tool longevity, better stability and the ability to use very enormous depths of cut and larger feeds. The chipformer, deforms and breaks the chip into rib type curved sections which can easily be removed from the cutting area. The insert has a frontal clearance angle of 3.7 with a 6 side clearance angle to allow machining to a 90 shoulder. Depth of cut up to .315" and facing depths to .126" at up to .047" IPR are obtainable with Heliturn.

When compared to CNMG/M 16... or WNMG/M 13... insert sizes with the equivalent corner radius, much greater tool life can be envisioned when using the LNMX 1506..-HT insert. Iscar has recently included a smaller size to the Heliturn family - the LNMX 1104..R/L-HT insert and tool holder for the medium application range of up to .197" depth of cut. The new insert features all of the blessings of the larger insert. This magnifies the economical advantage in the medium machining application compass. 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 expected. The inserts are obtainable in .031, .047 and .063" tool nose radii. Heliturn inserts are available in the most superior 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 offered in 1, 1.25 1.5 and 2" bar sizes. Also attainable are exchangeable heads. These tool holders have Iscar's unique Hard Touch coating, which extends holder life and prevents corrosion. As a result of the positioning of this insert, machining next to the tailstock is achievable.

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

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

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