On the Rockwell vertical milling machine, because of the way its built, lubing the Z (knee) way is very easy so are the Y ways on the table, but the X ways are a chore. Your trying to lube the underside of the table, hardly a clean or effective way IMO.
About 2-3 weeks ago, I saw an inexpensive one-shot lube pump, that ended up being about $50, with shipping and sales tax. While I was waiting for the pump, I disassembled the table off of the mill and proceeded to drill my oil passages, cleaned the way and gib and lube the pieces and reassembled the mill and adjusted the gib.
I ran all of the necessary piping on the mill, made the line orifices and left a flexible whip, to connect to the pump, allowing for the table Y movement. Today, I was working in a yogurt and cottage cheese plant, on arrival home the pump was setting on the kitchen table. The pump was piped for 3/16 tubing, I was running 1/4 tubing, retapped the pump outlet fir 1/8 pipe. I mounted the pump on the mill knee, connected the flexible whip, filled full of Vactra 2 way oil, and gave it 3 pumps and I had oil at the orifice fittings, two more pumps and I had oil on the X ways. So another successful job in the shop.

Thats pretty cool. How often does it need to be lubed? BAck in high school machine class we lubed machines with a squirt can made more of a mess than lubing the machines.

Nice job Jack and the one-shot lube pump is the only way to go and uses less oil and less mess.
-
I normally oil the ways, maybe once a month depending on the amount of mill usage, or if it starts to drag as I move the table or knee.

That looks like a quality unit, what`s the brand a model?

That's pretty neat!

Jabber,
I bought it off the eBay store for Eisen Machinery, its a Chinese pump, made by Chen Ying, model #CLAB-8, it was roughly $40 plus freight.

I see you made your own orifices for the system. I've always used Bijur metering orifices as I have them in stock from maintaining the punch presses. The presses had Bijur automatic oilers that activated every stroke so the flow had to be tightly controlled so you didn't have a flood of sticky tackified way oil dripping off the machines.

I took the 1/8 npt x 1/4 compression 90 elbow, I threaded the inside of 1/8 npt pipe thread, to accept a brass 1/4-20 set screw, then drill the set screw with a .050 drill, to make the orifice fitting.

I took the 1/8” npt x 1/4” compression 90 elbow, I threaded the inside of 1/8” npt pipe thread, to accept a brass 1/4’-20 set screw, then drill the set screw with a .050” drill, to make the orifice fitting.
I'll have to remember that Jack. What a great way to make your own orifices. Thanks.
