1942 Van Norman #12 Milling Machine
Ser #12-6184
Here it is in action, about halfway through its first cut in who knows how many years.
About 2 seconds after the cutter entered the work for the first time. No noises, no chatter, just chips.
And it's about over... Less than five seconds to go. 3/8" HSS endmill running at 480rpm. Feed at 1 1/2" per minute. .060 depth of cut. Material is 4140 steel.
