I wanted to make the A-axis strong enough so vibration would no be a problem.
I had some steel plate ( 8 mm ) laying around so that would do.
Welded a strong support were the motor-reduction could be bolted onto.
Motor is a 1.5 KW YASKAWA servo connected to a 1:18 reduction.
As this reduction has some very heavy bearing in it that would just be fine.
As for now I leave it as it is but the axis still has to be centered by means of 3 setscrews.
Main setback is that this drive is needing 3 x 220 V so I had to arrange for that also,having a transformer 3 x 380 V to 3 x 220 V for my lathe all I had to do was making an extra outlet.
Next thing to do will to make the adapter piece for a 4 way jaw chuck.
Before I could mount everything in the machine I had to make the base plate as well.
Made a base construction of some 25 x 25 mm steel rods. On top of this I mounted a white plastic-hardbord plate (10 mm).
By now the 4 axis is connected to Mach 2 at 100 pulses for 1° so that should be OK. |
