Hi guys,
I have finally found a good set of brushless drivers for the tamagawa TBL-S 300 watt brushless motors in the XY-HRS series NSK ballscrew driven slides I have. I want to build a quickie wood/plastic/laser router using these to offload that task from my Shizuoka cnc mill (because it likes to cut metal, but my wife likes things made in wood!). I have come up with 2 easy ways of throwing it together, using 3 slides, for a travel of 20 inches by 37.5 inches by 5 inches. These are the NSK XY-HRS H, M and S series slides. The 20 inch slide is made up of dual thk style linear rails with 2 blocks per rail and the ballscrew inbetween. The 40 inch slide uses a single wide rail (maybe 2.5 inches wide) with 3 blocks on it. Obviously, the 20 inch slide can support more of a moment arm, so idea #1 is to mount the 40 inch slide on top of the 20 inch slide, and have a small single rail with a short block on the far end to help with flexing (but these are very stout slides!).
idea #2 is to mount the 20 inch slide on top of the 40 inch slide, and again, maybe a small single rail to help flexing.
The z axis is just a short S series NSK slide with a smaller (100 watt) drive motor. It still has a 42 lb payload and a 55 lb thrust force!
Here are pics of the 2 ideas...suggestions? I want this to be simple, so I will get it done fast, say 1 or 2 weekends. The cost isn't bad..maybe $1200 total for the slides and drives by carefull ebay shopping over the past 2 years.
