Yes and no. Here's a pile of 19 polished stone axes:

They're admittedly different sizes, but the intent to churn them out is clear. These things were ambiguously tools or currency: they were transported long distances and hoarded.
There was another, older, stone age industrial site in France that produced thousands of beads. The way I remember it*, there was evidence that they fed themselves by trading beads for food. It's interesting to me that a stone age lifestyle might for some people resemble factory work.
*My apologies if I'm confabulating this. I think it was in the Loire Valley. I need to track down what exactly I'm half-remembering here.
This is an interesting counterexample, thank you. It seems that in some places, some standardization was already present back then.
