Hello Guys. It finally happened, my employer purchased a larger mill for the shop. It is a Cincinnati 430-18 horizontal mill with a vertical head included. It was actually delivered just before Christmas but just got it leveled and power to it 3 weeks ago. Keep in mind I have never operated any other mill other than Bridgeport type mills. This thing is a monster comparing it to our old Bridgeport. I probably only have about 8-10 hours on it with a lot of them installing the DRO. I have milled a couple projects and I like it thus far. Ive only found one recurring problem and cant figure out where to start troubleshooting the issue. I keep getting a lube oil failure light on the lube system. Sometimes it has run for 2 hours without coming on and other times only 30 minutes and it comes on. If I push the manual lube button it pushes a plunger up to contact a switch and the light goes out, most times. There has been twice where no matter how much I push the manual button the light wont go out. I can see lube oil on the ways so it is oiling some. How is this system supposed to work? I looked inside the control box and there is a timer in there set at 3 minutes, changed it temporarily to 2 minutes but the lube failure light came back on.
