I really like these videos!

Thank you! :)

Ich bin war dort als die VW TSi Maschinen gebaut wurden es war eine interessante Zeit.

I'd like to see a video about G320 or G520 machines.

[@Grobgroup]

Hi 😃, you can find a video about our G520 here: th-cam.com/video/9yyHfaVELT8/w-d-xo.html

In Deutsch hätte mir das Video besser gefallen.

It looks great, but what I see is reduced rigidity when your rotary doesn't have support and also sits on Y axis that have to go up/down which is in front right of machine. Looks like that X is the most rigid axis, then retractable Z axis column which is horizontally in the center inside of this machine. Plus on top is the tool changer. Just imagining if I have to repair something in bottom of Z axis. The only benefit from this design is that rotary table has better rotation which results in best tool reach to machine complex parts where other 5 axis machines would not able to do it. I would put Y axis below of X axis on lowered casting box design with 4 linear guides and 2 ball screws that goes up and down. It would make it more heavier but more rigid. Also spindle buried inside the Z column to reduce the height. Then since Y axis on right is gone, make that column shorter and on top of it put the chain tool changer. It just my thought.

I originally had the same concern with the Y axis. I visited Grob and discussed this and got to look into the machine up close. Concerns went down. Huge components hold it all together. Massive linear guides and balls screws. I then visited a large automaker who machines very large engine block casting die components on theirs for the last 4 years. They were very impressed with it. Programmers words were it was their most accurate machine. Grob has a very nice facility. These are proven machines with approximately 15yrs of history.

Nice Video, but as a design-engineer from a "small" competitor you show too much.
Don't show you genetics for free on youtube !

[@abdalrohmanmousa7405]

Any one can buy the machine and reverse Ingenieur it but no one can build the same quality and rigidity and give an excellent support

[@Dammes83]

@@abdalrohmanmousa7405 then buy a machine, disassemble it and find the right clue but don’t give it away for nothing.

This well-known configurations and most large and small competitors is capable of reverse engineering by looking at existing machines. Either way this isn't unique to GROB almost all CNC configurations are known there are next to none "new" designs
