VIBRA-FREE High Speed Machinig - 4 Axis

[thorfuss]

I work for GE Canada and is the best job in the world.

the contours are incredible!

i just reallly want to know how people made turbines before the great computerage.... ie; in the sixties already the jets were working with turbines, even the waterdriven powerplants used them... as precise these guys, i can figure out they even x-rayed the machinists too :-)))

make sure they're error fre:-))

Ya im sure mexicans can beat them out with a hammer.. I dont fly.. But Im gonna guess the more precise this is the better so yeah!

You could see on my movies the machining of a turbine blade in 5-axis simultaneous modus.

Machine tool typ LX 151 brand: StarragHeckert.

Best machine ever see for machining of turbine blades !

[lexichronicle]

they can be cast to rough and then machined, but basically they need machining and they need to be 100% fault free. i think they're even x-rayed to check for faults.

[maximebob001]

yes these pieces are under high pressure and if they fail people might die so everything is triple checked.

That is a very time consuming way to make turbine blades. Is there not a better way.

@enytned1 This was probably a prototype part or a demo of the machine; production parts like these are investment-cast, finish machined, then most likely x-ray and liquid penetrant NDT before they get shipped out.

@YoungJim409 this is a compressor blade. these are not investment cast, but machined from solid, pretty much as shown in this video.

[YoungJim409]

@jarekad Where do you get that idea?

[jarekad]

@YoungJim409 from a few years in the business. investment casting is mainly used for turbine (not compressor) blades and NGV's that have complex geometry, ie. internal cooling channels or cavities. By comparison compressor blades have a (relatively) simple geometry and are not hollow, so machining from solid, be it a rolled bar or a forging, is normally used. Let me just clarify - I do not mean that 17-4PH cannot be cast, but it not economical.
