I"m planning to use THK SR rails for X and Z axis on a fixed gantry, a set up where my y axis is on a horizontal traveling table. This guy,
http://www.5bears.com/cnc02.htm ,who seems to know his stuff,says SR series "need" to be used horizontally. THK web-site says "best" used horizontally. Does "horizontal" mean that only the traveling table on my set up is best use for these? I have a completed gantry set up with x and z axis already in place. Is it worth hunting up the prefered rails "(SHS (Best, 4-way loading, caged balls)
HSR (Good, 4-way loading, uncaged balls)," or is the distinction mostly applicable for high loads, industrial use?
Router is to be used for woodworking, -- joinery (dovetailing and mortise and tenon) with spindle horizontal to table, and inlay work with router in usual vertical orientation, professional use in a one man shop, whrere machine will probably only run a few hours a week. Thanks!
