Looking for info or manuals for old bijur lube... on BP series 1

[peter.blais]

Hi, My BP series one has an old bijur lube setup on it. Its mostly electronic with a pull up manual lube knob. I searched all over bijur's website but didn't find much, can anybody tell me what knobs / adjustment / whatever there is to this thing?

I can't tell if it does anything automatically or not, I don't dare just leave it for a week and see if it goes down,and I can't hear it doing anything over my rotary converter.

I'd like to find the info so I can wire this thing up or sort it out and be able to use it properly other then just pulling the manual lube all the time. It does flow lube correctly to all the different lube points when you do that though.

Can you post a photo of it? That might help members determine what you have.

if you have one similar to mine then it is run by a small electric motor. Whenever the spindle is running, the motor is running. It is geared really low and it pumps by slowly lifting the plunger and then letting it fall. If the motor runs then you should be good. How do you know its flowing oil correctly? Have you taken the thing apart to get to all the meters? If so, and it all works, you are lucky. Most have been clogged beyond repair.

If I pump it a few times manually in a short time I can visually inspect and see the way lube. It is evident on the quill, Y axis, you have to get pretty crafty with a mirror and a flashlight but it definantly does lube the x and the screws.

I don't think it runs in that case- I have never once seen the plunger lift on its own. I guess I"ll have to take a peek and see if its hooked up to power correctly and such inside the case. I do know the low lube alarm is just jumpered.

Ok, pretty much seem to have this thing figured out. It IS running, I just didn't realize how slow the cycle times are on these things until I looked at the link above. Only thing I wish is that it had some sort of manual lube so I could give things a squirt before I start moving things around for the first time of the day. I've just started pulling it up as far as it'll go depending on where it is in the stroke and then letting the machine sit powered up for a bit before moving it.

You should not have to do this. As long as you run your machine and on a regular schedule I would not worry about it Just pull it twice a day if it make you happy. You will just be wiping up more oil. As I always say "never pour, drip or use anymore oil, then you are willing to wipe up. . You also don't need to pull it up as far as it goes. The system has lines full of oil it not a true pressurized system, more of a drip type system

First time seeing this post. MSC has a parts list for Bridgeports in the back of the BIG BOOK. Go to www.mscdirect.com to get one.

You can also call Hardinge because they saved Bridgeport by buying them out, Thank God for that.

Yea, well, it took a lot of work on college student / garage tig welder wages to save up and buy this thing, and the ways are as-new... So i'm a little paranoid about keeping them that way. haha

The fact that the rotary converter is so noisey (I really do need to get an inverter for the spindle and use that converter as a paper weight) and the cycle time is so slow for the lube, not knowing what was going on with it was driving me crazy.

That, and the fact that I grew up racing shifter karts, and then raced open wheel cars- Things where you spent 10x as much time wrenching then using... The concept that there isn't a billion hours of maintance to be done is bugging the hell out of me. I feel like its going to explode into a million pieces when I turn my back on it.

I did a bunch of machining in school, I'm getting my M.E. degree, but we never had to do any maintance, all we did was sweep up our chips.

I have a boss5.
I had problems with my pump. No bigey. It pushed out the check ball holder for the pump. I checked all the lube points 1/2 were not getting oil. I cleaned all of them. I never could get the top 3 points working correctly with the rest of the system. I removed them from the auto system. I oil them manually now.
As far as the original pump. You can give it a shot manually as long as it is at the bottom or part way down the travel of stroke. If its at the top the stroke you will have to wait for the motor to move it down.
Do check all of the points for oil. The only way to do this properly is to disassemble clean and hook the oiler up to the parts as they sit on the floor. Each meter valve has its own filter I should have bought new ones but I just cleaned the filters and used lots of shop air to remove any debris.
Hope this helps

How do you get at the meters under the table, do you just undo the ball screw on the rigth hand side then slide the table across till you can get at them or does the table have to be supported or something.

Just as you mentioned......remove the nut on the X ballscrew and slide the table. Be carefull not to pull the table off the machine!! It is HEAVY!!!
