New Creative Tool Holders By Iscar Guide The Way In Machining Capacity
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 exclusive helical shaped cutting edge, useful for large depths of cut and greater than typical feed rate. The LNMX...-HT Heliturn insert is screw-clamped into the SLANR tool holder and reinforced 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 establish positive radial rake angles and soft penetration into the material being cut. The lower forces and smaller loads insure better tool longevity, greater stability and the ability to use tremendously massive depths of cut and larger feeds. The chipformer, distorts and breaks the chip into rib type curved pieces which can effectively 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 feasible with Heliturn.
When opposed to CNMG/M 16... or WNMG/M 13... insert sizes with the similar corner radius, much greater tool life can be foreseen when using the LNMX 1506..-HT insert. Iscar has recently included a smaller 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 revolutionary insert features all of the blessings of the larger insert. This heightens 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 significantly better tool life can be predicted. The inserts are accessible in .031, .047 and .063" tool nose radii. Heliturn inserts are obtainable in the most advanced carbide grades: IC9025, IC3028 , IC428, IC907, and IC908.
The external tool holders are offered in 1, 1.25 and 1.5" shank sizes. Boring bars are offered in 1, 1.25 1.5 and 2" bar sizes. Also offered are exchangeable heads. These tool holders have Iscar's unique Hard Touch coating, which extends holder life and hinders corrosion. As a result of the positioning of this insert, machining next to the tailstock is plausible.
The high positive rake angle of these tools allows 10-15% less power usage than conventional tool holders at the same parameters.
By utilizing Iscar's Heliturn tools, tremendous cost savings and profitability in lathe processes is guaranteed.
A Brand new 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 succession which considerably reduces the cutting forces. The insert's corner has a wiper arrangement which supplies high surface finish even at high feed conditions, which in abundant occasions can dismiss a finishing cut. The corner angle is 88 degrees which provides increased strength. The CNMX inserts were built for heavy machining applications. Their unusual design ensures dependable, fast metal removal when using 80 degree rhombic inserts. They can be mounted on any regular 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.
