Thank You. At the shop i'm currently working at we run another software but I like to hone my
MC skills as much as possible in my off hours.
Never know when you may be called on again to work with the software.
Thanks,
Steve
Dstryr,
I would believe that to be true, holding .0005” on a Hermle C400 day in and day out is why you spend the money you do for one of these machines.
The tolerances I stated above were worst case scenario.
The only thing we check while the part in the machine is bore size for the holes. We typically have .0002” tolerance on bore size so we error to the small side
and tweak the program to get the fit we want. Location is easily within .001” ALWAYS!
The biggest drawback that I see on the C400 is it’s 38 tool magazine capacity.
Matthew,
In aluminum we typically hold 0 to +.0005” on 3d form, finishing at 15000 RPM and feed of 250 IPM.
Hole in aluminum are typically all within .001” of true position, when checked as a cluster, no matter if is 5 holes or 25 holes, at any given angle.
In tool steel 3D form is typically +.0005” to +.001” finishing at 8000 rpm and 100 IPM.
Holes are the same as in the aluminum.
This one gets my vote.

We have two of these in house and a 3rd on schedule for December delivery.
You won’t be disappointed, they are absolutely INCREDIBLE!
