Relationship between Guide rail length and ballscrew length

[Lee Roberts]

Ok np glad was of help, you can always enjoy your machine once it's up and running and go on to make new parts for it if you want/need to, if you have a read up there are some good posts on here going over whip and the right rpm and so on for screw sizes.

Good luck with the build, don't forget if you need something slightly out of reach you can always post up for a quote.

Just some examples for design considerations. Here are 2 from the machine i just build.


1.At least around 200mm shorter ball screw here / depends on the design/. I saved from both ends






2. Here i also saved from both ends.


-Left side is calculated so that the spindle center/the bit/ reaches the end of the table, not the gantry carriage.
-Right side is obvious
+ the plate that is attached to ball screw housing also by being on the left and it shape / can go further right/ helps things and reduces ball screw length.



One of the pleasures is not only to save on weight, but to feel the deep satisfaction when looking at it and thinking " How well thought it is"
