Zirconium Again

[BrianP.]

I apologize for the first post. If it could be deleted that would be great. The boss does not let us connect to the internet and when I used his computer it locked up. It does not seem as if the content was posted although the topic got through.

 

We have a job in house and the material is Zirconium. The guy who is setting it up blew up 2 cutters just touching the part. Anyone have any experience with this?

 

Thanks

you are going to need diamond coated endmills at the minimum. and lots of coolant and rpms if the tools need to be small. diamond grinding also will work if you have the rpms for it.

NEVER plunge on this stuff, that's a QUICK way to grenade stuff. Ramp or helical 30%-45% max of effective diameter @ 1.5° MAX ramp angle (my preferance) if you must enter a closed pocket. Light radial cuts have worked for me, and as was mentioned flood the crap out of it with every available pump.
