Brand New Innovative Tool Holders Coming From Iscar Direct 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 utilizing a specific helical shaped cutting edge, useful for massive depths of cut and higher 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 provide perfect contact of the insert with the tool holders. The upper rake face of this insert is mounted level with the top of the tool holder to facilitate 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 metal being cut. The lessened forces and smaller loads assure better tool life, considerably more stability and the ability to use extraordinarily large depths of cut and elevated feeds. The chipformer, deforms and breaks the chip into rib type curved sections which can immediately be removed from the cutting area. This insert has a frontal clearance angle of 3.7 with a 6 side clearance angle to allow 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 contrasted to CNMG/M 16... or WNMG/M 13... insert sizes with the same corner radius, much improved tool life can be expected 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 common application range of up to .197" depth of cut. The brand new insert features all of the advantages of the larger insert. This enhances the economical usefulness in the medium machining application range. When compared to CNMG/M 43. 12... or WNMG/M 43. 08... insert sizes with the same corner radius, a substantially better tool life can be expected. The inserts are obtainable in .031, .047 and .063" tool nose radii. Heliturn inserts are attainable in the most excellent carbide grades: IC9025, IC3028 , IC428, IC907, and IC908.

The external tool holders are presented 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 enhances/increases/expands/heightens/stretches holder life and resists 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 standard tool holders at the same parameters.

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

A New 80 Degree Rhombic Insert with high helical cutting edge for high metal removal rates Iscar is presenting 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 extensively decreases the cutting forces. The insert's corner has a wiper configuration which produces high surface finish even at high feed conditions, which in numerous occasions can take out a finishing cut. The corner angle is 88 degrees which provides increased strength. The CNMX inserts were produced for heavy machining applications. Their unique design ensures constant, fast metal removal when using 80 degree rhombic inserts. They can be mounted on any conventional tool holder that carries conventional CNMG inserts, but the seat has to be replaced with a special seat: TCH 4. Iscar's R-clamp tool holders are highly recommended for heavy machining applications.
