What is the most accurate CNC?

[cooler21]

Hi! I want to ask you what is the most accurate CNC machine for woodwork? I have read something about 0.001 mm . And have heard that Shizuoka and Mitsubishi are maybe the most accurate. I do not know. Does anyone know it? Thanks

I belive 0.0001mm is more then enough for woodwork since wood will expand depending on the humidity. Which machine is more accurate i have no idea .

[Zumba]

I believe the Norwegian company Bergerking makes a router called the "Bjornwhoppervaluemeal" that has .000001" (one microinch) accuracy.

Don't they also run a double?

The double isn't out yet. They're having trouble with ballscrew whip on the 8" diameter screws. I think they're now working on 10" screws.

On the otherhand, they debuted the "Junior" at last year's IWF. It's meant to go head to head with the "Sixpiece" from the Irish CNC Company, MacNugget.

I confirm the availability of the "Junior". I have taken delivery from local distributor.

Yeah, and you can't forget the fact that when you decide to buy, they always make sure you "HAVE IT YOUR WAY". It's really the service that makes the sell!

walter, howd that "Junior" work out for you, was it worth the money?

I looked into getting that "Junior" also, I think I'll hold out for the "Double", I think it will be worth the wait.

What do you guys think about KFC, they really got a leg up on the competition, from what I hear.

When I was buying our cnc machine. To separate the fly poo from the pepper I had them both send me a ball bar (renishaw) test report on the machine I was going to be purchasing (make sure the serial numbers match to the report). You will know weather it is BS or not by holding the reports together. They will tell all on accuracy, slop and servo timeing. See if they choke or send it quickly. By the way I do ball bar testing on the side. Iso 9000 requires it in machine shops.

I don't think any wood cnc will hold anything close to that!

[Zumba]

Yea, it's a ridiculous number that's more or less meaningless, especially for woodworking.

.001mm, or .00004", is beyond the accuracy of most ABEC 9 bearings.

[Switcher]

I bet you could get that accuracy, If you had a "9.99 domino", not to mention all the extras they throw in!

Shizuoka and Mitsubishi would both be good machines. Shizuoka was the builder for the Okadas I use to work on. I have pitch error comped them to .002 um. And that was 8-10 years ago. I am sure they are even tighter now. That was on a metal cutting machine but I am sure the technology follows. Mitsubishi makes good controlers also. I am just the most familiar with Shizuoka.
