Impeller machining on five axis StarragHeckert machiningcenter

[rocketpropulsion]

Really nice work! I can honestly say I've never heard of StarragHeckert but I can guarantee I won't forget it.

Just one software malfunction at the end and its all over. The wonder of machines

[honeybunchickens]

jet engine compressor, nice

[rguerzo]

Thanks for the video. I'm looking for a company that owns this type of machine (or even similar) in the Philippines. I'm an industrial designer who design parts and build prototypes that frequently needed CNC machining services. For now, I need to travel to Hong Kong and China to have the parts done which is costing me more time and money. Can anyone tell me where I can avail such service in the Philippines? Thanks.

[PoopSwindler]

that is a nice tool cutting with the whole edge and getting no chatter

[nandha0150]

.Though initially during machining it was horrible sight... The finished product was ABSOLUTELY SEXXY..........:D

[michael2nicolaisen]

Which cam system was used for programming this impeller?

[Starrag01]

@michael2nicolaisen - Starragheckert PSI+, PSI+ constitutes dedicated CAD/CAM software designed for the efficient programming and therefore milling of multi-blade components such as impellers, blisks, bladed rotors, diffusers, compressor and pump wheels and even nozzle guide rings.

[michael2nicolaisen]

@Starrag01 Is this PSI+ based on hyperMILL multiblade?

[Starrag01]

@michael2nicolaisen - yes the basic is hyperMILL

[douro20]

What is the material?

[Starrag01]

@douro20 - Aluminium

[755hp]

@Starrag01 Was it forged??

[vifcirth]

@755hp its a compressor wheel for a model jet engine like the jet cat P200 - at full thrust its compressing 375 liters of air a second and rotates with 112.000 rpm - so very high precision is necessary...

[leadorg]

what sort of coolant is this?

[XXINTL]

@leadorg i might be wrong, but it looks like Shell - Dromus B

[Starrag01]

@XXINTL we use Blaser Swisslube

[basimpsn]

The beauty of computer running a machine. By hand this would take weeks

[lexichronicle2]

The blade geometry on things like this is so impressive. It's clearly taken a battering in some flow modelling software.

[schwinn434]

Absolutely excellent; it is one of the most amazing things I've seen. I can't imagine the machining and programming work that must have gone into the design of this machine; as someone who doesn't not a lot about CAD/CAM what type of software is used to program this machine. Is it graphical oriented in nature? Again, absolutely amazing machine. Keep up the great work!!!!

[aa209999]

what a fantastic machine

[passani1]

Impressive! Is this video footage shown at real speed, or sped up to cover the entire process?? Looks extremely fast to be live footage speed....

[dickisalzburg]

@passani1

its normal speed take a look on the water ;)

[JZA70]

thats the coolest thing ive ever seen

[deaftodd]

I f the end mill is long and thin, do they flex a little?

[arnold02000]

@deaftodd Depends on the spindle speed, cutting load (feedrate) and materal being cut. So, yes, they can flex. However, the shorter tools flex too under the right conditions.

[DarryllK]

@deaftodd it would be a carbide tool taking light fast cuts so there would only be the smallest amount

[aryesegal1988]

@deaftodd they always flex a little, even if they're big and buffy... ;)

[CropDuster33]

@deaftodd If the feed rate is high enough then it will flex, but 99.9% of the time that wont happen because the spindle rpm is around 1500 - 2000+ rpm witch is really fast! so the depth of cut isn't that deep.

[GeneralG1810]

Thats cool, it looks similar to an impeller off a Napier turbo dont suppose anyone knows if it is or not?

[ProteinBoogers]

Can you make me one?

[PeterTenev]

nice job ! that's a mixed flow turbine impeller xD

i wanna buy one of these, coz i'm working on a project - 120 CFM of air with pressure 6 Bars but... :-( i can't find any info here... stupid country :- (

[RivelDog1]

very nice

[Grischa187]

amazing

[seremexico]

cooooooooooll

[Marco9641]

wonderfull!

[ozarkalfa]

FIRST!!

Sweet video, by the way.

It's..so...beautiful...

[master7447]

amazing thanks for sharing that

[leviterande]

wow

[benspeed1974]

i have been wondering for years how compressor wheels are made, fantastic!

[junglehead99]

Really impressive
