Indexing is fast and convenient due to the threaded connection. Since the tool is not removed from the machine, there is no setup time for head replacement. Excellent repeatability is now possible and resharpening of tools is no longer needed The unique cutting edge geometry axially directs the resultant cutting forces towards the spindle. This results in high stability and enables machining at high feeds, even with long overhang. In addition, the tool features 4 flutes comprised of an ultra fine grain substrate and is protected by the advanced AL-TEC coating technology.

As the milling capabilities of CNC turning centers improve, so too must the cutting tools. The ability to use live tooling in a CNC turning center has been around for quite some time.
This ability has enabled companies to complete parts in as few setups as possible ideally one. Of course, cutting tool suppliers must adapt whenever spindle capabilities increase. Typically, solid carbide round tools drills and endmills are the cutting tools of choice for driven tool applications. This led ISCAR to design a new generation of indexable tooling technologies that effectively support the milling applications being addressed with driven spindles.
A great fit for this environment, these new indexable and interchangeable cutting tools are expected to provide gains in productivity with design characteristics such as:. In manufacturing, accuracy should be a given. However, in cutting tool terms, if you can pull off accuracy in an interchangeable system while maintaining excellent rigidity, you can consider that a success. In its current form, the Multi-Master system provides users with more than 40, potential combinations, including a wide variety of interchangeable heads that can be used with shanks of various types and lengths for slotting, shouldering, chamfering and more, all while maintaining accuracy and rigidity.
Shank types include steel, carbide and heavy metal in both straight and conical taper iterations. Multi-Master is being further expanded to include degree heads with 1. Because of the number of flutes in their design, the newly added heads for facing FM type drastically increase productivity while producing excellent surface quality.
These heads can perform effective shoulder milling, as well. Nano- and micro-sized end mills and drills, made from solid carbide rod, have been in the market for years. ISCAR has recently introduced nano- and micro-sized indexable inserts. The ability to press these very small inserts has opened the door for production of the smallest diameter, multi-flute, indexable milling tools ever produced.
ISCAR can now produce a 0. Spindle output characteristics—such as HP, torque and speed—are other important aspects for optimizing cutting tool utilization. It is also important to note that the part features typically machined in this environment are relatively small. While not as common as conventional milling and drilling, slitting is also another operation performed with driven stations.
To allow for an indexable approach, ISCAR has introduced the narrowest indexable slitting line available. Previously, it was only possible to perform a slitting operation under 0. Regrinding changes the diameter, thus the potential need for slight programming changes or offsets. In addition to reducing setups, SlimSlit offers another advantage over HHS and solid carbide: chipformers that allow higher chip loads, which enables higher table feeds, further reducing cycle time.
With a variety of offerings, SlimSlit not only reduces number of setups but also simplifies tooling inventory and eliminates the need for regrinding the tools. Use of indexable tooling in this small work space environment produces many benefits—economy, simplicity of tool management, reduction of potential errors when renewing the tooling and more efficient use of the carbide materials.
With an increasing demand to do more in one set up paired with the trend to make smaller, lightweight final products, ISCAR is thinking forward to provide the best machining economics. In an industry where every second makes a difference and every movement counts, an innovative approach to even the most basic cutting tool can contribute to increased productivity, less waste, and ultimately lower cost per part.

Indexable Milling Tools for Driven Tool Stations on CNC Turning Centers
Iscar Metals Inc. A new cutter can be assembled by selecting a milling head, which carries inserts with the required shank diameter, length and shape. This reduces tool-change time and establishes a platform for thousands of machining environments, according to the company. Search form Search.
Originally a family of rotating tools with interchangeable cutting heads from solid carbide, it had a serious impact on the development of cutting tools. Now the family has a strong presence for manufacturing in various industrial sectors. The success of the thread connection, in which the thread is produced directly on a solid carbide part, has changed pre-existing views on the reasonable Enables machining with larger overhang. Same head can be mounted on metric and inch combinations.
