Great content , dude! I was a Hardinge CNC assembler for 5 years . Assembled mills , lathes and replicated cylindrical grinders . Also did some work on Yang Mills until the USA plant basically closed . I built many but never ran any so I love what you are showing us
If you think this is amazing, check out "Carnaghi" CNC machines. They build machines the size of entire warehouses for machining nuclear reactor components and other massive parts. Getting accuracy in a small machine like a Haas doesn't impress me, it's all on a single frame. Getting accuracy from a spindle mounted on something the size of a gantry crane... that impresses me.
Just found this channel. Any videos where you actually show the head fixture itself? It seems like it bolts to 2 of the exhaust head holes one on each side and one side has an eccentric bolt/ rotation hole, but is that sufficient clamping to handle the machine loads? Do you then bolt up the other exhaust flange holes? My thought was how it might dish lower in the center of the head. Also with iron heads that weight must be quite massive and I’d be a bit concerned about how it was clamped and supported. I assume the plate you have is custom made, I’m assuming it bolts directly to your A axis bore line bar or is it a seperate fixture with its own axis rod.
I'm usually only taking off .005" at the most, so the fixture is sufficient. If I were cutting heavier loads, it wouldn't be ideal. For the cast iron and wider heads, I will put a stanchion under the middle of the head opposite of the plate for added stability. I have not noticed any difference from a distortion standpoint in the head with it being mounted this way. I custom made the plate and it does bolt to the a axis bar that I use to hold blocks. There is a flat in the bottom of the bar for the plate to sit on.
@@paragonengines1924 Thanks. Another question I had. You had a few videos where the I think 0.007 had to be removed because the leading or trailing edges of the head were low. However this is the same area that you indicate your Z. So how do you know that the head is actually trammed in flat (parallel to the A axis) vs skewed where it’s mounted lower on one side. On SBCs the cylinder head face isn’t parallel to the valve cover side so how do you have a true reference? I suppose you could have indicated along the whole X to look at the flatness in Z but still a fair question of skewed mounting vs head warpage. I understand with a block you machine to the crank mains bore centerline which is trued up with your A, but the heads don’t have such a datum reference or am I missing something?
When I level the head, I pick 3 points to create a plane. usually, 2 points on the right side of the head and 1 point on the left. Any variance from that plane is what needs to be fixed. The plate has a tilt to level the x axis, and the a axis levels the y.
There is an easier way to record while in jog. Push position button, jog button then page down button, select desired axis and push origin button, that zeros the axis just like a dro.

Awesome! I would say that running the machine is fun if you enjoy machining!
@@paragonengines1924 I'm sure I would enjoy doing what you do .
It's fascinating that a machine so large with so much movement can move so precisely.
It is incredible when you first watch it, and this is just a "Medium machine" according to Haas!

Man that ending made me think for a second that the CNC was going to machine itself.
It gets close, still a little scary and I've run it 100s of times!
Great content. I recently purchased a used Centroid machine and I am in the middle of trying to learn to write my own probing cycles.
I bet you'll have some fun!
I subbed. Great videos.
Thank you for the support!
why not level it end to end first in X with the eccentric and indicator , then let the program and rotary level it in Y ?
You could do it that way, no question. I just prefer to get it flat first and then check the x-axis.
Love the video. Think your shop needs a Rottler machine in addition to the HAAS mill!
If I only had enough porting work to justify that awesome machine!
