DGNC - A New Parting Insert with Direct Jet Cooling
ISCAR is introducing an upgraded DO-GRIP parting insert.
The DGNC insert is the best solution for grooving and parting on high temperature alloys and on stainless steel.
The insert features a coolant hole that passes through the insert, with an outlet near the cutting edge. The new DGNC inserts were designed for parting and grooving on stainless steel and high temperature alloys.
When machining stainless steel or high temperature alloys, the temperature near the cutting edge becomes very high.
These materials tend to adhere to the cutting edge, causing built-up edge. This phenomenon can be reduced or even eliminated, by efficient cooling of the cutting edge.
In grooving and parting applications, there is a problem that the chip prevents the coolant from reaching the cutting edge.
The new DGNC inserts are an ideal solution, as they have a coolant hole through the insert with an outlet near the cutting edge.
The coolant reaches the cutting edge and the insert body is internally cooled.
Materials such as titanium, inconel, or austenitic stainless steel tend to strain hardening during the cutting process and they form long and tangled chips. The efficient coolant supplied to the cutting zone decreases flank and cratering rates. This leads to substantially longer tool life and a better machined surface finish. The coolant supply can be attached directly to the DGFH-C blades used on the regular blocks, or through the SGTBU-C blocks which have coolant passages and connecting ports. In the first stage ISCAR will provide the 3 and 4 mm insert widths in the C- and J-type chipformer configurations with neutral and angular frontal cutting edges.
Heavy Duty Grooving System
New line for deep heavy grooving with a unique frontal locking mechanism.
The TGBHL tools feature a user-friendly clamping and extraction device. They have an internal cooling system directed to the frontal cutting edge, which increases tool life in deep grooving applications.
A New 80º Rhombic Insert with High Helical Cutting Edge for High Metal Removal Rates
ISCAR is introducing the CNMX 1207..-HTW insert family.
The new insert has a very positive radial, helical cutting edge and a positive rake angle - a combination which substantially reduces the cutting forces. The insert's corner has a wiper configuration which produces high surface finish even at high feed conditions, which in many occasions can eliminate a finishing cut. The corner angle is 88° which provides increased strength. The CNMX inserts were designed for heavy machining applications. Their unique design ensures reliable, fast metal removal when using 80° rhombic inserts.
They can be mounted on any standard toolholder that carries standard CNMG inserts, but the seat has to be replaced with a special seat: TCH 4. ISCAR's R-clamp toolholders are most recommended for heavy machining applications.
In order to facilitate our customers in selecting the correct grade for their applications, ISCAR has developed new coating processes for the new SUMO TEC grades which will feature different colors for easy identification. All former SUMO TEC grades featured the same gold color.
The new coating technology improves the insert life by 5 to 12%, compared to the previous coatings.
ISCAR's grade IC6015 is a complementary SUMO TEC CVD coated grade for high speed machining of stainless steel.
ISCAR also offers grade IC6025, which covers the application range of M15-35 used for roughing and interrupted cut applications at medium to low cutting speeds.
A cobalt enriched outer layer substrate, with MT TiCN and alpha Al2O3 coating with a special post coating treatment, provides substantially improved tool life, and excellent edge performance and repeatability.
Turning stainless steel at medium-to-high cutting speeds under stable or slightly unstable conditions.
ISCAR Grades Relative Application Range for Machining Stainless Steel
Recommended cutting speed for grade IC6015 should be at least 20% higher than the speed recommendations for IC807.
As a result of the increasing popularity of Turn-Mill machining centers, ISCAR has decided to expand the range of exchangeable head tools.
ISCAR has developed a range of HSK A63 WH toolholders and tool adapters for Turn-Mill machines. These holders comply with a new HSK standard interface, recently introduced under the ICTM standard - Interface Committee for Turn-Mill and Mill-Turn machines.
The ICTM standard’s objective is to improve the angular positioning accuracy of the turning tools by tightening the tolerances between the spindle drive key and the holder key slot. The designation for the new standard for turning tools is HSK A63 WH….
The advantage of adopting the new HSK A63 WH standard is the ability to use the rotating toolholders from the conventional CNC machining centers on the multifunction Turn-Mill macines as well.
A clamping screw pushes the shank of the tool through a narrowed opening forcing
elastic deformation of the steel holder and face contact.
As the steel contracts around the tool, contact is made around slightly more than a full 180°.
The result is rigidity comparable to a solid part.
