micro endmills

[Joeyls319 5]

Hello all

Does anyone out there have any recommendations where to get micro tooling, more specifically a .5mm endmill?

I need to look at other suppliers to try out.  The ones we use now don't last very long.  

We are cutting at 66,500 rpm in .5mm thick titanium.

 

Thanks ahead of time

Joey

To increase your tool life I would suggest a ramp entry if you are not already doing so, vertical entry can damage your tool right off the get-go.Also avoid presetting with a probe if you can or use a reduced feedrate if that applies to you.As for supplier microcut is a good brand. I think the website is microcutusa.com

Thanks Peter

Im already ramping and we are using a laser to touch off the tool.  I will

have to check out the website you posted.

thanks again

Mikron make some small endmills. Their small drills are outstanding.

No experience with 65K rpm in TI, but Harvey Tool rocks

When you get this small I actually think Harvey Tool sucks, their run out and diameter tolerance in this range is going to give you grief. Not that I dislike Harvey Tool at, but when you get into cutters under 1mm, everything gets a lot more important, really quick. Union Tool is usually my go to for this type of stuff - not the best, but still very good, and pretty affordable for what you are getting.

^^^^These guys have tiny stuff

Richards Micro Tool either makes or used to make all of the harvey miniature series. Good stuff.  https://www.richardsmicrotool.com/

Kyocera is also very good at the small stuff.  http://www.kyoceramicrotools.com/micro/milling/square-end.html

Looking through that PMT site, they have sub .001" endmills.  .001" and up actually have a square end cut. 

How do you generate enough rip-em's to use a .001" endmill????

Someone at a trade show once told me that Harvey doesn't actually make anything

The are just brokers selling other peoples products

I do not know if that is true.

There are becoming a presence in the industry though having gobbled up Helical and Micro100 recently

There's a grind shop in Kalamazoo MI That does work for Harvey.

Hitachi would be my first choice followed by OSG. Both pricey, but Hitachi endmills are simply the best I have ever used.
