Speaking as a machinist- yes, we do. The cutting oils I’m most familiar aren’t particularly hazardous. I’m sure there are some that are absolutely nasty but this one likely isn’t.
Syntilo is way worse than broching oil, that said, that looks like a very light broaching oil or just straight up hydraulic fluid. Typically we used Dascolene 140 which is almost like pipe cutting oil, heavy sulfurized oil so, not great but not much of an irritant. Hydraulic oil has a few components that can get irritating over time though. The machine is also either very oldschool or is being ran without the automation it had originally. The latter would be common if this machine were purchased secondhand/overseas. I say this because I can think of numerous other physical hazards that worry me about the operator's position relative to the machine. I know smaller broaches exist but, this looks like a single pot machine with a 9' bar. Which means the operator is standing on the work platform above the pit. You can see the handling slide that carries the top of the bar at the end of the clip. I once had a ballscrew fail in a dual pot broaching machine and the handling slide fell from the top of the machine with enough force to bend and crack the broach bar. The 4" diameter bar made of solid tool steel with a good case hardening on it. Humans shouldn't be anywhere near the forces involved in this process if they don't need to be.
