Combining three milling functions into one cutter reduces tooling inventory costs and simplifies programming when machining cast irons, steels, and ferrous and non-ferrous alloys.
Securing higher performance in milling
High productivity and security is offered by the Stellram 7702 multi-functional tooling intended for mould and die machining and milling operations in the aerospace and automotive industries.
The insets most suited for high cutting speed and low cutting feed when milling these difficult to machine materials.
ATI Stellram X-Grade technology utilises a novel proprietary substrate that includes Ruthenium alloy in the carbide structure to produce the world's best milling grade to date, claimed the company.
The grade offers the following.

Complex internal and external cylindrical profiles, as well as single-point threading and grooving, are generated by Stellram's wide range of Posimatic inserts and tools.
Mini tooling grooves, threads and bores
Stellram's Ultra-mini programme, consists of replaceable carbide tools that locate in a common steel shank. The tools cover application ranges for grooving, threading and boring in small parts.
* Superior thermal cracking resistance and propagation.
* Three times higher metal removal rates.
* Longer tool life than conventional cutting tools.
X700 Grade inserts are available in a variety of 'A' styles, square, round and octagonal for a wide variety of applications.
Coupling X700 with new insert geometries produces an excellent combination for machining aerospace alloys.
The X-GradeT product range also includes the new X400 grade for milling steels and hardened steels under the most demanding conditions and the established X500 grade for higher feed rates for all material applications.
One of the challenges in machining high temperature, heat resistant alloys comes from the edge failure due to thermal cracking.
With its X-Grade inserts, ATI Stellram has solved this problem by going to the heart of the matter: the carbide structure itself.
ATI Stellram has a novel substrate creates a stronger bonding matrix.
X500 is ideal for machining alloys like ATI Allvac Ti-5-5-5-3 Alloy (Ti5553) and ATI Allvac Ti-10V2Fe3Al Alloy (Ti1023).
"Not only do they last longer, but testing shows production speeds even with really difficult-to-machine materials can be as much as three times faster," said Dave Watson.
There is no sacrifice in tool life with the faster production speeds, and there is also less risk of insert failure that could damage expensive components.
He said: "With titanium usage rising rapidly, it's important that tool performance be exceptionally good with these metals".
ATI Stellram is a business unit of ATI Metalworking Products, an operating company of Allegheny Technologies, a leading producer of specialty metals, including titanium and titanium alloys, nickel-based alloys and superalloys, and stainless steel and specialty alloys.
