New Solid Ceramic Endmills for Machining Nickel-Based Superalloys
New solid ceramic endmills for efficient machining of superalloys, cast iron and graphite.
Following the steady increase in the processing of nickel-based high temperature superalloys (HTSA), such as various grades of Inconel, Incoloy, Haynes etc. in the aerospace industry, and the demand to decrease production costs (CPU), ISCAR is introducing new solid ceramic endmills. The new endmills can also be successfully applied to productive roughing of cast iron and graphite.
The new tools enable increasing the cutting speed by up to 50 times when compared to carbide tools, thereby drastically saving machining hours and reducing production costs.
There are 2 configurations:
E3 - with 3 flutes for shouldering applications
E7 - with 7 flutes, feed mill style for rough applications
The endmills are produced from two ceramic grades:
IS6, designed specifically for machining HTSA
IS35, intended for cutting mainly cast iron and graphite
Reduction in process times on nickel-based superalloys such as Inconel, as well as cast iron and graphite
Available in 6 to 20 mm diameters
Relieved neck diameter behind the effective cutting edge for machining next to shoulders
Recommended cutting speed up to 1000 m/min
Average tool life on superalloys is 15-25 minutes
Note: The current sintering process produces tools with a slight color difference.
The color difference has no influence on tool performance whatsoever.
7 flute cutters
3 flute cutters
Ceramic tools behave differently than carbide tools. In most cases, the end of a tool life is
determined by the acceptable level of burrs and not by wear size
Only air coolant should be used
Use with the same types of toolholders as carbide EMs (shrink,collet etc )
