VMC 40 Table Replacement

[easternmachine]

Has anyone replaced a table on a VMC40 or similar model? I have a couple of conflicting versions. One stated that the tables are custom fitted and to change one could become highly involved. Another version is that it is no problem that the new table top will need fly cutting, and the program is already in the control. I am considering a new table because my turcite is peeling off and the table has numerous holes and dings. I would probably have to fly cut the table any way. If anyone has any information on this process, please let me know as I am trying to decide the best path.
Thanks.

You have to consider the cost difference between the two. Just like a used car, ask yourself, 1)is it worth fixing, 2) would it be cheaper to repair the machine or replace the machine? After you repair or fix the machine, is there any other issues with it? ie are the ways for Z and Y in good shape? How old is the machine? With the flux of alot of shops going out of business, you may be able to find a replacement at auction. That being said, If you can get a new table, is it just the table or table saddle combo? If it is just the X axis that is damaged, it would be cheaper just reworking the table with new turcite and a fresh cut on the table. You will also need to address the issue of what caused the turcite to wear/start peeling to begin with. As they say, anything can be repaired..... for a price.

Yes, the program is inside the control, with all your programs and tooling data backed up, type in ta,2 at the command prompt, and a slew of service programs will be loaded into memory, anywhere from 30 to 50 programs. If you wanted to type the program in by hand, justt look in the back of your maintanence manual, they are listed there, provided you have a blue or beige manual. As far as fly cutting the table yourself, it can be done, Fadal uses a custom made fly cutter to do the job. Just make sure the machine is square, tight, and tram is as close to zero as possible before you start. Any error in the machine WILL show up in the cut/flatness of the table. If you cut the table without fixing the turcite, it will be just a bandaid, and at that point it will be a matter of when you are going to dispose of the machine.
Hope this helps,

i would have thought the turcite was on the saddle ?

replacing the turcite is not that hard compared to your other choices

like gaswiz69 said , you need to find out why the turcite was damaged , i know wd40 can damaged turcite

for the top of the table , I've seen people use liquid steel and then fly cut the surface

Most common reason why the turcite is damaged is because of the lack of waylube getting to the turcite. You might want to check to see whether the lube manifolds are clogged up or if the lines are damaged.

Have you inspected the saddle as well? We can repair the table for you but we would recommend taking a look at the saddle as well. Not sure who told you the tables are custom fitted...doesn't sound correct at all. Why would you have custom pieces machines that are assembled on an assembly line?

What you will need to do is figure out your gibs/straps size once you repair the table. This is something we can definitely help you with. Feel free to send me an email or call for more info.

I found the turcite problem while checking the lube system. The lube system had problems, I replaced the table/saddle manifold and the filter on the pump and the flexible hose to the saddle. The turcite has peeled off approx. 12" on the front left x axis way and approx. 8" on the rear right x axis way. It appears to be intact in the center and to the ends except for the above. The ways still look good.

I have not looked at the y-axis turcite, the ways still look good and the wipers are all intact. I will do this after I remove the table.

I found a new table with the turcite installed and it was suggested that it could be a lot of trouble to get it adjusted properly to an older (1988) machine and the top would have to be flycut.

I may be interested in a quote to repair. I am trying to determine all options.

I cannot guarantee whether it would work or not without seeing your table and the new table...too many variables.

I know for certain that you would have to adjust your gibs/straps.

Feel free to send me an email so I can help you figure out your best option.

Holy cats do not replace your table because it just needs Turcite. Turcite is cheap and installation is way easier than buying a new table. Turcite that is under your table doesnt takke more than a day to fix.

Hi!

I have some questions:

1) mill table (O5831): what kind of tool I have to use here? a pic would be cool!
2) scrape table (O5830): are this the little round tracks in the table, and what kind of
tool i have to use here?

if i right, to run scrape (O5830) before mill (O5831)?

3) after I've renewed the tucite on the table, do I have to grind the turcite and mill the table?

bye

Mill first, then scrape. I milled my table. Only because it was crowned.

Theses aren't mine...

That aint scraping. Thats just to make it look good.

Hi,

@mniadna
cool videos - thanks.
What tool do you use for milling the table?
In the viedo it look like a miller with one tooth.
Do you have a pic from your tool?

@underthetire:
I think milling only is okay - I don't need this scraping.

Thomas,
This is what I used. It is a fly cutter that I welded to a toolholder.
