Possible to use quick extrusions high-precision assembly?
(OP)
Hi all,
As most of you know, quick aluminum extrusions are great to save design and manufacturing time, but have some downside in term of quality level and durability (screws tend to losen-up overtime) (see "Design A" as typical quick extrusions and bracket that can be bought on McMaster)
In "Design A", positioning of the 90' bracket in the groove is done by a "straight locator" creating a slack of 0.025''
In "Design B", positioning of the 90' bracket in the grove is done by a "tapered locator" eliminating the slack as the screw is tighten.
If "quick extrusions" were done like "Design B" could we use them for high-precision machines (e.g., CNC machine) or tooling?
Thoughts?
