Sub 10 micron. Jfc, this idiot doesn’t have a clue about auto manufacturing. Even the most precise parts of auto manufacture don’t require “sub 10 micron” tolerances. Engine bearing journals are about the most crucial fit in a car and they are generally on the order of 50 microns. Electric cars can use even wider margins because they mostly use ball and roller bearings instead of babbit bearings.
But… Since were talking about the body panels on the worlds dumbest truck the point is even more moot. John Delorian was stamping out stainless panels in the 80s on a shoe string budget,
but the worlds richest dipshit wants to make it out to be the automotive equivilant to brain surgery.
10 micron refers to the decimal places in machining.
Having a tolerance of .01 mm isn’t crazy on some parts.
Molds for injection molding for example
I’m well aware of how tolerances work, I’ve worked in automotive manufacturing since 2016 and currently run the maintenance department at a tier 2 manufacturing facility.
Injection molding is able to have tolerances in the hundredth of millimeter range true. But metal stamping is not as precise.
Cool
I’ve only been in it a few times and only short term.
My work was in other industries
I think my point was that most people don’t understand tolerances and what a micron means.
Everyone seemed to understand just fine.
Most importantly, Elon has no clue what a micron means.
His email says ‘all parts’ so 0.01mm on a door panel is ridiculous.

You’re both right, the above poster meant 0.001mm. Tolerances are called out in mm for the most part, unless you live in freedom eagle land, in which case 10 microns would be “about four tenths of one thousandth of an inch”

Here is an article about this
Yes that is also true but in mfg people call out microns in a funny way.
Decimal places so less than .xx would be considered 10 micron as a tolerance
