Efficient impeller machining on five axis Starrag STC 800 machiningcenter

The efficiency of radial compressor wheels depends to a high degree on the precision of the production process. This is something to which we are well suited as a worldwide recognised specialist in the field of 5D milling technology, as high-precision machining of impellers has been one of the specialist areas of Starrag for many years. With the STC 800 we have set another milestone for turning and milling applications.

2:12.. 🤯
When you realize what a massive compressor wheel this is.

It's beautiful art 😍. 👌🏾

[@dracorodriguez2387]

good finish

[@XaymacaJah]

nice work.

[@taystew]

impressive

[@StefanoLinguanotto]

What type of coolant are they using? Never seen a green one!

[@quillmaurer6563]

For reference, how large is this impeller? In the machine I'd assumed it might have been 15-20 cm across, say for a 2000hp engine or so. But at the end it looks like it's hanging from a hoist and a couple meters across. What is it used for? I would assume some sort of turbocharger - ship engine?

[@StarragTV]

The impeller has a diameter of approx. 750mm, he is part of ship turbo charger

Thanks

[@peterjackson6556]

Well done. This is very interesting. Who is the tooling supplier for the taper ballnose cutting at +- 3min?

[@bernhardbringmann2262]

Peter Jackson The ballnose cutter is from Starrag. Tools for flank finishing of Impellers is their speciality. Contact is [e-mail] :)

How much time it will take to machine full impeller??

[@michaelmckinley4588]

HOLY GHOST THAT IS BEAUTIFUL. the machine and the product.... if it does not violate the NDA, what is that impeller for?

[@StarragTV]

That's for a ship engine

[@kdoran709]

Crazy

[@bartdereu9267]

I wonder how they build compressors like this for the 1940's first jet gasturbine engines.

[@justiceanddevelopments873]

Really Awesome. But Can you tell me sir. How I can learn or from I can learn , how to make Centrifugal Compressor ?

[@siyumtsega6498]

what is the material???

[@nukeboy27]

Aluminum alloys
