New Productive Tool Holders From Iscar Lead The Way In Machining Capability



Iscar's Heliturn system features a unique, double-sided insert with 4 cutting edges for Fast Metal Removal (FMR) turning. The new Heliturn is a tangentially clamped insert utilizing a distinctive helical shaped cutting edge, useful for tremendous depths of cut and greater than normal 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 assure 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 disturbed by clamps or the tool holder body. The 4 curved helical cutting edges insure positive radial rake angles and soft penetration into the material being cut. The reduced forces and smaller loads insure better tool life, elevated stability and the ability to use tremendously tremendous depths of cut and higher feeds. The chipformer, deforms and breaks the chip into rib type curved sections which can conveniently be removed from the cutting area. This insert has a frontal clearance angle of 3.7 with a 6 side clearance angle to permit 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 opposed to CNMG/M 16... or WNMG/M 13... insert sizes with the identical corner radius, much better tool life can be expected when using the LNMX 1506..-HT insert. Iscar has recently released 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 revolutionary insert features all of the advantages of the larger insert. This enhances the economical advantage in the medium machining application extent. When compared to CNMG/M 43. 12... or WNMG/M 43. 08... insert sizes with the same corner radius, a much better tool life can be expected. The inserts are obtainable in .031, .047 and .063" tool nose radii. Heliturn inserts are presented in the most exceptional carbide grades: IC9025, IC3028 , IC428, IC907, and IC908.

The external tool holders are offered in 1, 1.25 and 1.5" shank sizes. Boring bars are available 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 thwarts corrosion. As a result of the positioning of this insert, machining next to the tailstock is possible.

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

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

A Unique 80 Degree Rhombic Insert with high helical cutting edge for high metal removal rates Iscar is introducing the CNMX 1207..-HTW insert family. The new insert has a very positive radial, helical cutting edge and a positive rake angle; a unification which considerably decreases the cutting forces. The insert's corner has a wiper arrangement which produces high surface finish even at high feed conditions, which in abundant occasions can dismiss a finishing cut. The corner angle is 88 degrees which provides expanded strength. The CNMX inserts were designed for heavy machining applications. Their unique design ensures constant, fast metal removal when using 80 degree rhombic inserts. They can be mounted on any regular tool holder that carries typical CNMG inserts, but the seat has to be substituted with a special seat: TCH 4. Iscar's R-clamp tool holders are highly recommended for heavy machining applications.
