One thing to be aware of is that the different builders are using different standards to measure the accuracies and repeatability.
The German DIN standard is different from the Japanese JIS standard and different again from the ISO standard. The standards are interesting when you see the...
Parts are kind of big to just ship about if they are being machined on an old G&L.
Lots of good videos are available from the best builders. videos are linked to the link below.

In most large machine shops, maintenance is involved in these purchases. Buy the right machine and it is a twenty to thirty year every day production machine.
An investment of over $500k needs someone skilled to program it. Simple large parts are not simple. Machines move within a .001 inch tolerance over meters. Often weldments do not. A 3 meter wide by 5 meter long with a right angle head would be my choice to start looking at. Less than a...
There is not a test result because it is not a test you would do on a machine tool. Pushing on the head or table tells you nothing except how a lever works. I have personally moved larger 40 inch VMC's by pushing on the table. More than tenths. It just showed I am large and can move a mass. If...
And yet, there are a group of machines built to run at full rapids in extreme high production factories at 24/7 paces and last for over a decade without ballscrews and guides failing. Small 30 taper VMC's by the two big brands, Fanuc and Brother.
Mike,
There are a bunch of excellent mid to large Swiss shops in San Diego county. My concern would be that you really are not set up to go after medical work and owning a single Swiss machine is a bit hard. Once you learn the guide bushing ins and outs and then how parts process differently...
This is interesting. I am have been in shops in that height range in the US, Japan and Switzerland and never had anyone mention the machines needed special accessories to function.
Control also includes motors and drives but the mechanical spec is slightly different and there are minor changes to allow for even quicker part productions.
