New Innovative Tool Holders Coming From Iscar Guide The Way In Machining Productiveness

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 using a specific helical shaped cutting edge, useful for considerable depths of cut and higher 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 assure 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 enable chips to flow across the insert, without being complicated by clamps or the tool holder body. The 4 curved helical cutting edges assure positive radial rake angles and soft penetration into the metal being cut. The lessened forces and smaller loads assure better tool life, more stability and the ability to use tremendously large depths of cut and higher feeds. The chipformer, distorts and breaks the chip into rib type curved pieces 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 obtainable with Heliturn.

When opposed to CNMG/M 16... or WNMG/M 13... insert sizes with the same corner radius, much better tool life can be foreseen 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 common application range of up to .197" depth of cut. The brand new insert features all of the advantages of the larger insert. This magnifies the economical advantage 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 much better tool life can be predicted. The inserts are accessible 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 attainable are exchangeable heads. These tool holders have Iscar's unique Hard Touch coating, which extends holder life and resists corrosion. As a result of the positioning of this insert, machining next to the tailstock is attainable.

The high positive rake angle of these tools 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 processes is guaranteed.

A New 80 Degree Rhombic Insert with high helical cutting edge for high metal removal rates Iscar is introducing the CNMX 1207..-HTW insert family. The completely new insert has a very positive radial, helical cutting edge and a positive rake angle; a incorporation 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 several occasions can dismiss a finishing cut. The corner angle is 88 degrees which provides increased strength. The CNMX inserts were designed for heavy machining applications. Their unusual design ensures dependable, 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.
