Hmm interesting from what I gathered about the M7HP I think the HP stands for “high precision” it has finer ball screws and better scales for better positional feedback... would you consider them more accurate then let’s say a HAAS? Also you’d think there has to be something special about them to justify the up 100k price tag for a machine.... like I said I don’t really know much about them just trying to gather some more info on them! Thanks
It's high precision for a router ? It's basically a beefed up gantry router not in the same league as real machine tool
When someone says high precision to me I think Hermle, Okuma and Makino … Maybe OKK and some Matsuura.
Ask them for ball bar tests and test sheets...
For accuracy I'd take HAAS over a Datron…
However Datron has super fast spindles for tiny tools.
Accuracy and precision are two different things and 40K spindle can do things that a 10K spindle cannot.
The Datron is GOOD for exactly what their videos show it be good at... Flat Aluminum and plastics and the occasional musical instrument like a "flute" on a cobbled together 4th axis.
No free lunch I'm afraid :-)
Pick up the phone and ask for test sheets and the realistic expectations for precisions and accuracies as well as precisions and accuracies on ISO type test parts. They are German they will know exactly what you are asking for.
Does it have 3 to 5 micron circularity as cut (or 8 to 10 micron part accuracy) … I don't think so same for ball bar tests...
What are the reversal spikes like... How is the machine thermally controlled etc etc etc etc etc...
The Datron IS what it is … If that suit your application and wants then FANTASTIC (sports fans)!
The term
"High Precision" is truly
meaningless without actual values and tests sheets as well as numerics stated to actual statistical relevance / use of standard deviations etc. [One sigma, two sigma etc.].
Like DMG Mori brochures always say "Highest Precision" … I'm like highest precision in reference to what... ? [In reference to the same model of machine they made 20 years ago ?].
Blah blah blah ad infinitum (lecture not necessary).
