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

Iscar's Heliturn model features a unique, double-sided insert with 4 cutting edges for Fast Metal Removal (FMR) turning. The new Heliturn is a tangentially clamped insert having a exclusive helical shaped cutting edge, useful for immense depths of cut and greater than normal 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 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 disturbed by clamps or the tool holder body. The 4 curved helical cutting edges provide positive radial rake angles and soft penetration into the metal being cut. The decreased forces and smaller loads provide better tool life, better stability and the ability to use particularly tremendous depths of cut and greater feeds. The chipformer, deforms and breaks the chip into rib type curved fragments 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 grant machining to a 90 shoulder. Depths of cut up to .315" and facing depths to .126" at up to .047" IPR are obtainable with Heliturn.

When opposed to CNMG/M 16... or WNMG/M 13... insert sizes with the identical corner radius, much enhanced tool life can be expected when using the LNMX 1506..-HT insert. Iscar has recently released 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 unique insert features all of the advantages of the larger insert. This magnifies the economical benefit 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 far better tool life can be expected. The inserts are offered in .031, .047 and .063" tool nose radii. Heliturn inserts are obtainable in the most superior carbide grades: IC9025, IC3028 , IC428, IC907, and IC908.

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

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, huge cost savings and profitability in lathe processes is assured.

A Unique 80 Degree Rhombic Insert with high helical cutting edge for high metal removal rates Iscar is unveiling the CNMX 1207..-HTW insert family. The new insert has a very positive radial, helical cutting edge and a positive rake angle; a blending which largely reduces the cutting forces. The insert's corner has a wiper arrangement which produces high surface finish even at high feed conditions, which in several occasions can omit a finishing cut. The corner angle is 88 degrees which provides expanded strength. The CNMX inserts were created for heavy machining applications. Their unique design ensures reputable, 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 recommended for heavy machining applications.
