Hi there,
I'm building my first moving table cnc machine. I'm going to use kanya PVS extrusions. While working on a design, I faced a question do such profiles have enough surface tolerance to mount hiwin rails on it? Product manager gave me an answer that they can give some extra work on surface so it will have 0.25mm surface tolerance on the length of 1200mm, but in general DIN EN 12020 says it to be 1.3mm on the length from 1000 to 2000mm, So my question is for those who've built their routers using extrusions - have you done extra surface machining before mounting rails to the extrusion or you've just compensated flexures (if it is suitable word here) of frame by making proper tuning of your software?
