Stell frame cnc 1500X1000. Adjustable table your opinion please

[ba99297]

The Bed being a separate unit means the outer frame pieces support the bed material at the edges, the way yours is drawn the edges will be unsupported and could bend or flex under cutting conditions.

Excuse me Dean but i don’t understand why my cutting table has unsupported edges. At every plan the cutting table beams are welded at the side pieces. Could you please make it more clear?

Ba99274 any of the frames shown including your own designs will be good enough so don't worry you won't go wrong.

Thank for your good words. The truth is that i don’t have time pressure. When i make a step i want to be sure about what i am going to do
I am searching over the internet for this construction about a year
The last few months although i thought i knew very much about the subject i find out that mycncuk exist
The answers that i take from the members make me change many of my thoughts
For example i didn’t know that the ball screws have critical speed. My first plan was to connect the motors straight to the ballscrews. Imagine how i would fell when i broke a ballscrew 1500 long running at 3000 rpm. I also thought that I beam is the strongest type of beam..... ( May be for vertical forces )
So every day someone in here give me an advice or correct me, i fell happy about avoiding another mistake

Thanks everybody so much for your help
P.S Sorry for my English
