Hi everybody
Long time has passed since my last post
It is because after summer holidays, schools starts and (as I am a school teacher-computer science) I had too much work.
Last night I decide to restart by installing the hiwin profiled rails
I start with X axis in order to install the master rail. I measure, I mark the holes and then drill with 4mm first and then with 4.2mm in order to tap the m5 bolts.
Then I bolt two carriages on a steel plate st39 ( not perfectly milled yet ) and then I put the carriages on the rail. The movement isn’t very easy. As I put pressure on the plate, the movement become easier ( as cause of preload overcoming). I didn’t lubricate the rail or the carriage for this first test.
I didn’t epoxy level the 80X80 beams (where the rails rest) as when I test them against straight edge I didn’t notice more than 0,15mm gap, so I will go on with shimming.
My questions are

  1. Do I have to lubricate the carriages for these first test travels
  2. What will be the normal pressure for moving the carriages
  3. As I apply force in order to overcome the preload forces I hear a sound from the carriages (krrrrrrrr ) is this normal?


Later I will come with photos and videos to show how the carriages move.

Thanks for your time
