New Prolific Tool Holders By Iscar Lead The Way In Machining Capability



Iscar's Heliturn model features a unique, double-sided insert with 4 cutting edges for Fast Metal Removal (FMR) turning. The revolutionary Heliturn is a tangentially clamped insert utilizing a special helical shaped cutting edge, useful for hefty depths of cut and greater than common 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 establish 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 permit chips to flow across the insert, without being disrupted by clamps or the tool holder body. The 4 curved helical cutting edges insure positive radial rake angles and soft penetration into the metal being cut. The decreased forces and smaller loads insure better tool lifespan, considerably more stability and the ability to use particularly enormous depths of cut and greater feeds. The chipformer, distorts and breaks the chip into rib type curved sections which can efficiently be removed from the cutting area. The insert has a frontal clearance angle of 3.7 with a 6 side clearance angle to permit machining to a 90 shoulder. Depth 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 equivalent corner radius, much enhanced tool life can be predictable when using the LNMX 1506..-HT insert. Iscar has recently included a lesser 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 revolutionary insert features all of the precedence of the larger insert. This enhances the economical benefit 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 far better tool life can be predicted. The inserts are obtainable in .031, .047 and .063" tool nose radii. Heliturn inserts are offered in the most superior 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 attainable 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 prevents corrosion. As a result of the placement of this insert, machining next to the tailstock is conceivable.

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

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

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