New Innovative Tool Holders By Iscar Guide The Way In Machining Efficiency



Iscar's Heliturn system features a unique, double-sided insert with 4 cutting edges for Fast Metal Removal (FMR) turning. The completely new Heliturn is a tangentially clamped insert utilizing a specific helical shaped cutting edge, useful for considerable depths of cut and higher than standard feed rate. The LNMX...-HT Heliturn insert is screw-clamped into the SLANR tool holder and braced 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 the insert is mounted level with the top of the tool holder to enable chips to flow across the insert, without being complicated 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 ensure better tool life, more significant stability and the ability to use extraordinarily enormous depths of cut and larger feeds. The chipformer, distorts 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 doable with Heliturn.

When contrasted to CNMG/M 16... or WNMG/M 13... insert sizes with the equivalent corner radius, much greater tool life can be foreseen 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 new insert features all of the advantages of the larger insert. This boosts the economical usefulness 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 significantly better tool life can be predicted. 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 available in 1, 1.25 and 1.5" shank sizes. Boring bars are presented in 1, 1.25 1.5 and 2" bar sizes. Also presented are exchangeable heads. These tool holders have Iscar's unique Hard Touch coating, which enhances/increases/expands/heightens/stretches holder life and prevents corrosion. As a result of the positioning of this insert, machining next to the tailstock is plausible.

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, big cost savings and profitability in lathe operations is insured.

A Revolutionary 80 Degree Rhombic Insert with high helical cutting edge for high metal removal rates Iscar is announcing the CNMX 1207..-HTW insert family. The completely 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 heightened strength. The CNMX inserts were built for heavy machining applications. Their unusual 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 advocated for heavy machining applications.
