Hello. I have in my possession an EMCO Maximat V13 lathe and I have the original thread dial indicator. My lathe is metric, and I do not have the small chart for the thread dial indicator. Does anyone have this specific chart and could provide it to me?
|
dunno about v13but this is the one for s11 if your leadscrew has the same 3mm pitch and your dial has 14, 15 and 16T gears than this should work
good luck

Hi Vedran
I am not familiar with the V13 so maybe one of our members who has one can help
I have a couple of spares lists for it? . .? the one doesn’t show the thread dial indicator at all , while the other only shows one with a single gear
Regards,
Carvel ?

My lathe has a 6mm pitch

Hi Manolis (?)
Trying to figure out what’s what with the thread dial indicator for a V13 according to the manual
Did you get the indicator with the lathe or add it afterwards ?
Can you maybe take a picture of it for us ?
Many thanks

If you have the dial indicator at least similar to the one I posted, then you'll need to multiply/divide the numbers by two but in general it should work. If you have a single gear thread dial than you won't be able to cut most of the pitches. Also check how many teeth your gear has, if it's not 14,15 and 16T you'll also have some conversion factor to apply. You should pick one of the more convoluted combinations and try what you get

Of course, you can math the thing out if that is your strength

Of course, you can always install the Rocketronics.de ELS and that will take care of any feeds, threading, taper, and radii cutting.?

I tried to work with this specific program ? to generate a small table, but what confused me in the process is the part where you declare how many lines the dial has. The division of the lines when I choose 6 lines is not the same as mine

Markings mean different things on your dial and on the calculator.?
Calculator simply marks positions 1 through 6 at 360/6=60° apart. It then lists which of those positions you can use for which pitch.
On the dial (and more importantly the Emco list)
markings
are organized differently 1 is 360°, one full rotation between
engagements 1, 2 (engage on either) is 180° so only half rotation between engagements 1, 3
(engage on either)
is 120°? -> 1/3 rotation between 1, 2, 4
(engage on either)
is 90°-> 1/4 rotation between
Note there is no just 2 or 2, 3 or 1, 3, 4 etc. as those combinations don't make sense, just as 1,2,5 wouldn't make sense in the calculator because they would produce uneven intervals.
If they had space on the dial, 1 would have 3 markings 1 2 3 4
2 would have 2 markings 2 4
Then the table would only say stop on each 2 or stop on each 4 etc.
In other words , these would then represent in how many sections a full revolution is divided.
Long story short, you have to make a translation table to get from one to another, and to do that you
first
have to realize Emco actually has 12 divisions but not all of them are shown. This is because you have both 1/3 and 1/4 circle divisions and you have to include both, so you have to go to 1/12 or 12 divisions in the calculator convention. Also note the calculator doesn't actually list the positions Emco omitted so you're good there. Here's a picture to make it a bit more clear.  Having run the calc for 6mm leadscrew
and for the 3mm
It quickly becomes obvious why S11 has 3 gears, but your V13 only needs 2 - with a finer leadscrew you need 16T gear to cut 0.8, 4 and 8mm pitches, but on the coarser V13 leadscrew you only need 16T gear for 8mm pitch which they probably concluded you don't need anyway.
NOTE, however that 3mm calculator doesn't completely agree with Emco table, for instance, calculator claims 0.4 can be cut with 14T gear, while Emco table says you have to use 16T. One of them must be wrong but I don't know which one. Thread carefully - pun intended :)

I found this threading dial indicator on eBay. It has 12 divisions.

Vedran,
Both are correct as you need a multiple of 2, which is present in
14/1 and in 16/4.
Here is the output of my calculator which shows why 16/4 is better
than 14/1, time-wise:

Thanks Bo?o
I assumed that this note in the manual applies only to imperial threading and empty positions in metric table are no-go, but I see now that all empty positions work for any engagement
