Brand New Productive Tool Holders From Iscar Head 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 brand new Heliturn is a tangentially clamped insert with a specific helical shaped cutting edge, useful for huge 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 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 permit chips to flow across the insert, without being afflicted by clamps or the tool holder body. The 4 curved helical cutting edges ensure positive radial rake angles and soft penetration into the metal being cut. The lower forces and smaller loads establish better tool longevity, considerably more stability and the ability to use tremendously tremendous depths of cut and greater feeds. The chipformer, deforms and breaks the chip into rib type curved segments which can successfully 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 identical corner radius, much enhanced tool life can be envisioned when using the LNMX 1506..-HT insert. Iscar has recently added 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 completely new insert features all of the blessings 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 far better tool life can be expected. The inserts are available in .031, .047 and .063" tool nose radii. Heliturn inserts are attainable in the most advanced carbide grades: IC9025, IC3028 , IC428, IC907, and IC908.

The external tool holders are obtainable in 1, 1.25 and 1.5" shank sizes. Boring bars are offered 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 placement of this insert, machining next to the tailstock is achievable.

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

By utilizing Iscar's Heliturn tools, tremendous 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 unveiling the CNMX 1207..-HTW insert family. The brand new insert has a very positive radial, helical cutting edge and a positive rake angle; a combination which extensively reduces the cutting forces. The insert's corner has a wiper arrangement which supplies high surface finish even at high feed conditions, which in numerous occasions can dismiss a finishing cut. The corner angle is 88 degrees which provides expanded strength. The CNMX inserts were created for heavy machining applications. Their distinctive design ensures reliable, fast metal removal when using 80 degree rhombic inserts. They can be mounted on any conventional tool holder that carries standard CNMG inserts, but the seat has to be substituted with a special seat: TCH 4. Iscar's R-clamp tool holders are highly favored for heavy machining applications.
