Completely New Prolific Tool Holders Coming From Iscar Head The Way In Machining Capability
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 distinctive helical shaped cutting edge, useful for huge depths of cut and higher than normal 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 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 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 material being cut. The lower forces and smaller loads ensure better tool life, elevated stability and the ability to use extremely tremendous depths of cut and greater feeds. The chipformer, deforms and breaks the chip into rib type curved segments which can conveniently be removed from the cutting area. The 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 feasible with Heliturn.
When contrasted 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 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 new insert features all of the advantages of the larger insert. This heightens the economical usefulness 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 presented in the most advanced 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 available 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 enhances/increases/expands/heightens/stretches holder life and thwarts corrosion. As a result of the placement of this insert, machining next to the tailstock is permissible.
The high positive rake angle of these tools allows 10-15% less power usage than conventional tool holders at the same parameters.
By using Iscar's Heliturn tools, huge cost savings and profitability in lathe procedures is insured.
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 considerably reduces the cutting forces. The insert's corner has a wiper configuration which produces high surface finish even at high feed conditions, which in abundant occasions can take out a finishing cut. The corner angle is 88 degrees which provides expanded strength. The CNMX inserts were developed for heavy machining applications. Their distinctive design ensures reliable, 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 replaced with a special seat: TCH 4. Iscar's R-clamp tool holders are highly recommended for heavy machining applications.
