Just a curiosity question but these chinese machine's look so strong yet most on average are entry level machine's and the frame isn't always truly flat. I know they use cast iron but do they beef them up and paint them to help sell or something? If you look at the blue elephant for example they look alot more commercial and well built then a well built DIY one. I know the chinese ones have cheap square rails and use shitty R&P setups and bog standard electronics but purely for the looks what is stronger their cast iron machine's or mild steel box section DIY with aluminium extrude gantry?

I've seen some videos on where they make them in a large factory and I see no cnc machine's that help make a cnc machine so it's like they don't machine anything.

I ain't buying one it's just a curiosity question about why they look alot stronger then a DIY but are actually shit on some cases

Thanks
