Ceramic cutting tools are.
Ceramic cutters for inconel.
These are great tools for production parts when a statistical analysis of tooling cost vs labor can be made.
Starting with a solutionized piece of inconel is optimal because it helps to limit the amount of work hardening.
Ceramic cutting tools for continuous cuts.
Being able to make fast continuous cuts is important for minimizing the risk of work hardening to occur mid process.
It is recommended that ceramic cutting tools be used when working high nickel alloys in order to achieve long uninterrupted cuts.
In contrast an xystin 1 insert can run at 350 to 400 sfm whereas a carbide tool would reach only 150 to 180 sfm.
Use ceramic cutting tools for continuous cuts.
This reduces the wear and tear placed on machining tools.
11000 rpm ceramic bits chewing through inconel as if it s butter.
Being able to make a fast continuous cut is important for minimizing the risk of work hardening mid process.
Avoid peck drilling with inconel.
Top 7 tips on machining inconel hastelloy monel and other nickel alloys.
With an ingersoll ceramic insert some creative toolpath programming extra attention to heat management and a willingness to burn through inserts to maximize throughput the busy ball turning operation has quadrupled throughput.
Ceramic turning and ceramic milling drastically increases metal removal rate in roughing operations but requires experience.
New whisker reinforced ceramic cutters are also used to machine nickel alloys.
Faster material removal than carbide for certain metals.
Apart from these methods inconel parts can also be manufactured by selective laser melting.
They remove material at a rate typically eight times faster than cemented carbide cutters.
Pushing the envelope with inconel machining.
Applying ceramic inserts is not a simple substitution of one cutting tool material for another.
There are significant process considerations that shops should examine carefully in order to realize performance and tool life expectations from ceramic inserts.
For instance when machining an imbalanced part made of inconel 718 with a hardness of 46 to 48 hrc the low end cutting speed needed for ceramics to plasticize the material is about 550 to 600 sfm.
