Tramming my Round Column Milling Machine

- During some recent face milling I realised that I never trammed my Milling Machine, it was clear in the result. I was getting 'irregular patterns on the work piece.
This went a lot quicker than I expected and I am really happy with the result.
Meaning of tramming:
Tramming ensures that the mill head is perpendicular to the mill table's X and Y axis. This process ensures that cutting tools and the milling surfaces are perpendicular to the table. Proper tramming also prevents irregular patterns from forming when milling.
I used a little different technique on my RF 30....I rotated a dial indicator from left to right of the bed on the x axis without moving either x or y. Got it to within 0.002 inches with 3 layers of soda can shims. Did the same for y axis. Didn't try the test indicator with higher resolution yet but I think this is close enough for me.
Thanks for watching and taking the time to provide feedback on your method.
They make an epoxy to do what you did without shims.
Once I installed my machine permanent I will be doing this, but for now thats on wheels should be fine for now. Thanks
Hi Super Pedro, That's great, hope my video will help. If you have any questions when you do it, you welcome to post them here. It may still be worth checking it now, just to make sure it's not too far out for items you manufacture between now and when its mounted permanently.
Mate, you need to move the indicator over the table not the table under the indicator. You are measuring the angle of the table not the head. If you can rotate the head instead of using shims. If there is no adjustment mechanism use a long bolt or some all thread and a nut as a jack, you an get it spot on in on time. Thanks for taking the time to post.
Hi Robert, Thank you for the comment.
Unfortunately the only adjustment I can make for 'head rotation' is on the base, which is why I thought measuring the table would be okay. I only did a brief swing test, I could probably have spent a bit more time on it rather than the table movement. I learn from these comments, so thank you and thanks for watching my videos, even though this one looked horrible :)
Well done mate, you ae working with what you have been dealt.@@qsworkshop
It might just be me but I can’t see the dial of the indicator for the first part.
Don't worry, its not you, its my terrible attempt at recording :)
You could have edited/sped up much of the table mvt &/or sweep, especially since the dial can't be seen, (better lighting will improve detail images; inadequate light will cause blurred images as much as an out of focus lens.)
Combine the slow table mvt & sweeps w/ the music and, frankly, I had to backup a couple of times because I dozed off.
And this is something I NEED to learn & do for the 1st time.
Hi George, Thank you for the feedback and appreciate you hanging in there. I'll take all this into consideration to make future videos better.
Hello you tramming head only on x but in y you don't check....
Hi William.
Thank you for your comment. You are correct, I appear to have edited most of the "Y" tramming out. Between 5:10 and 5:30 I move from the right to the left of the table in one move to determine the variation. I did not cover it very well, my apologies.
I appreciate the feedback.
Regards
Quentin
@@qsworkshop and the fault was at least 0,25 mm in Y plane over about 100 mm table width, so the Y is mutch worse then the X was in the beginning.moving the table does not give you any tram measurement.
try again
@@jozefa1234exactly! I was going to post that too. In the Y, he measured table runout, not head tram. A totally different problem. Properly done, the table is locked before running a tram test, though on big machines it isn’t 100% necessary, but should be done.
This is NOT tramming! Please educate yourself and perhaps repost an actual demonstration
Thank you for your feedback. Please share your advise on tramming and the actual way to do it in your opinion.
