Relationship between Guide rail length and ballscrew length

[Boyan Silyavski]

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"
