I work as a salesrep for a big company selling thermically cut platesteel IE laser, plasma and gas and now my brother and i will be building a CNC from scratch. I have a few questions regarding my design choices though And hopefully you guys can help me prior to orderering the bulk of the material.
This is the Z assembly with integrated v bearings for the y axis. The Y axis will in turn be belt driven as will the Z axis. Also i know that i have to add some spacers in between the carriage and groove bearings (or thread some holes).
Now for the questions to the pros:
1: the groove bearings will ride on 2 pieces of steel and 1 set will be adjustable up and down (as have been done many times before) but do you guys think that a laser cut rail will be holding tolerances ok?
2: The Z carriage will be 1 piece and the fit will be adjusted with the adjustable v groove bearings (as excentric spacers are very expensive). What about the tolerances on the z carriage riding surface? Will it be ok you think?
