Get mersmerised or if Airsoft Innovations get their way, get turned on watching this Sear Ring in action as part of their Machine Porn Series... "Hardinge T42 with C-axis and Live Tools, this part runs unattended 24hrs/day! Sear Ring normally runs in 12L14 steel but now running in brass because we cannot run the steel without coolant on. Turn the coolant on and you can't see anything."
