Need Help!- Series 1 CNC table removal

[TarHeelTom]

Have a number of lube metering units not feeding oil. As most of these are located under the table, need to remove the table.

Is there an existing thread discussing table removal?

Thanks

i had to remove the table on mine also. i have a series 1 ez trak sx. to remove the table unhook the wires on the servo motor. take the cover off the belt for the motor. unbolt the motor from the frame and maneuvar the motor past the belt. once thats out of the way you can remove the bolts holding the pulley on the ballscrew. then remove the spacer behind it. then you remove the bolts from the bearing retainer. then comes the fun part. remove the spanner nut on the ballscrew against the bearing. after that's off remove the 4 bolts holding the housing on. once those are out tap it off the table. now on the other end of the table remove the 4 bolts from the bearing housing just above the handle. once all that is done remove the gib from the front left of the table. now you can slide the table out the left side. it is a heavy little jewel.
Hope this helps. i have a complete manual with the torque specs for all the bolts if you need any of them

oh and whatever you do don't screw the ball screw out of the nut. not a good thing. there is 2 bolts holding the ballscrew nut in if you need to remove the ballscrew

Would love to have the torque specs for the bolts and nuts.

Major delay is to build something to support the table after I remove it. Thinking about just a 2x4 nailed to the wall, and a saw horse at the mill, and build a table to slide the mill table onto. Lower the knee to match the heights.

One thing which I'm considering, but haven't seen the underside of the table yet. Think seriously about moving the lube manifold from on top of the saddle to somewhere else, perhaps on the knee somewhere, and run just the post-metering lines up to where they disperse. Would make it much easier to service the lube metering units in the future.

Talked to a tech at a nearby machine maintenance shop recently. He told me that they main reason they stay in business is lack of lubrication.

Also planning to add a pressure gage to the lube line, tapped in just after the pump, but probably mounted up on the head or neck where it's visible. Should be handy, and helpful in seeing if all the metering units are working. If pressure is higher than usual, that probably means that I've got one or more metering units not working.

Thanks for the tips.

it might take me a day or so but i will scan the book on the x axis diagrams with the torque specs and send it to you. i have to tear my 2nd machine down to get it in the building then i will be free to get you the info. my 1st machine has a pressure gauge after the lube pump that has a adjustable marking needle so you can do as you said keep track of clogs.

the table on my machine is like 9" x 48" 2 of us set it off by hand. makes it a little easier if you run the table most of the way to the right. leaves less ballscrew in the way on the left when you slide the table off.

I'm pretty sure Tom has a Boss machine, so there is no similarity between his and your machines. The Boss machine turns the ballnut for the X axis and the ballscrew is mounted solid to the table on the right end. The table is NOT like the standard manual mill table as it is with the EZ Trak.

Hawkjet, you DO have a memory. Wish I had some.

yes, I have a BOSS machine....

Used a roll around tool box lower section years ago on a standard mill, ought to work on the CNC. Push the table out onto the tool box [maybe some wood on top] and roll it away

Excellent idea!

Just bought a roll around tool box recently. Good alternative use for it. Need to check the height and see if it is not too high.

Thanks

I had a s1 Boss 9 which is very similar to the BOSS 5 in mechanics.
There is a nut on the right hand side of the table that holds the ball screw to the table. Remove that. Loosen the X axis gib and slide the table off to the right. Watch the ball screw spring cover! The ball screw is keyed to the table.
