xzy zero plate

[Kyle Stapleton]

Just got my xyz zero plate back from the shop and looks great.
It was machined with in .0002", I know it is over kill but it was a donation to our cnc project.
Got the idea/drawing/files to make it work from Scott Worden.
Now I just need the Bot...

Very nice… Something the bot should come with, in my opinion!

Tolerance of 0.005mm ;)... That should be kept in vacum isolated box ...
Nice piece by the way :)

I am using precision milled CS plates post grinded on surface grinder pretty much within +- 0.01mm. Both plates are mirror finished and I can see my face on the movable as well as fixed Zero setter plate ... Your seems to me not that good as it has micr-tooling marks :p i am jealous;) The hole in your plate seems to me BORED on boring/milling machine... I doubt you can't get the HOLE tolerance of 0.0002" without using reamer or other finishing tools/methods

[Kyle Stapleton]

Yes, they did say the hole was not down to .0002" (how could you tell the it was milled and not reamed by the picture, I work in mainly wood so I do not have a clue).
The rest is smooth as glass, I know it does not look like it but it feels nicer then my IPAD screen.

I built one a couple years age but I find myself not using it. It does work very well but I now just use the C3 command f zero and the touch plate for the Z that way if I have to do a tool change the machine is starting from the exact same point

Kyle,
That looks great. I gave the plans to a machine shop and said "no hurry"
(bad idea) its been 2 months. Could I ask what they charged?
Would like to get one before I am so old I won't remember what its for.

[Kyle Stapleton]

It was a donation but, I did ask and he said about $300.00 (3hr shop time)
He mainly does work making injection molds for 3M and the Military.
