Lubrication for CNC

I have been scouting the salvage yards and auctions for used/surplus Trabon
( now Manzel-Lubriquip ) components and systems - I now have more invested
in pumps and divider valves than the new Rockford ballscrews for my
Bridgeport project. Information on these is available at
http://www.manzel.com/slidcard/spdv.html

These systems are usually engineered for the application. They are positive
lube systems that can be monitored by a switch on the divider valve
assembly. If a lube point becomes completely restricted, the cycle stops. I
came to the conclusion that this should be done if the knee is the powered Z
axis. ( I visited the local Centroid retrofitter and learned of the failure
they had due to lack of lube on the knee of one of their first systems. )

I use a mixture of Suniso 3G 150 refrigeration oil mixed with SlipCoat
additive ( Hapco Product no. 3616 Hapco Products Co. Box 26097 Fraser, MI
48026 ). The ratio depends on where I use the oil on my manual machines. I
still use Mobil Vactra for way lube on the Bridgeport and SB lathes. I had
a few gallons of the refrigeration oil in several viscosity's given to me 20
years ago but all that remains is the 150. I'll be watching the posts for
the day that I have to pay for the machine oil. BTW, the additive is
expensive & I am in no way an agent of the company. This stuff really does
make the oil cling to the bearings.
