Titanium question

[Eric T. Maier]

What type of cutters (end mills) would be best for machining titanium? I'm guessing carbide but any help on speeds and feeds would be appreciated.

Thanks,

Mer

No mill me but speeds and feeds would be sssloooooooooww

A friend uses a shell cutter, with round carbide inserts, says they work best. The speeds he cuts at are 75-80rpm, very slow, like Ferret said.

Use coolant, 130-200 sfm .0005 chip load per tooth.
No or than 1/2 the cutter diameter depths of cut.
Carbide cutters ti coated.

Thanks everyone.

I buy cheap carbide end mills and basically run them slow and dry. I dont have a coolant system on my mini mill but it would come in handy if I did!

BTW Mer, your right in my neck of the woods so to speak.
