42k spindle tooling

[EAGLE27]

We purchased a Mikron 5 axis mill with a 42k HSK spindle and I was looking for recomendations on tool holders. I've been told heat shrink is good but can be a costly startup. Also have been told that Schunk Tribos is good. Anyone using these types of holders at these kinds of speeds?

Shunk is very good. No matter what system you go with, it will be pricey. Keep in mind that with the tribos system that you will need one of their special hydraulic setters. With shrink fit, you would need either an induction shrink unit which is pricey but efficient, or the cheaper "hot air" type.I would also take a look at Nikken/Lyndex as this is what I have used in the Mikron our company had.

We use BIG mega chucks here on the high speed machines

We have 3 Mikrons (24000 rpm) here and a lot of shrink and rego-fix Powrgrip. They need to be balanced otherwise, you won't change tools, you'll change spindles. HTH!

We have 2 Mikrons here. One 3 axis and a new 5 axis LP macihine. Max rpm of both machines is 42k.

 

We use the MST brand heat shrink holders. We have the heat gun type of machine. I think the machine was around $3500 and the holders are around 120-150 each. We also have the shunk tribos unit. Not many holders though (pricey). Shunk hyradulic holders also. they are pricey also, but they are balanced to 32k IIRC.
