Which rotary table

[Anonymous]

I wouldn't worry too much about the relative sizes of the tables. My mill table is 9" wide, but my rotary table is 12" diameter. It's never really been a problem.

Hi

I also do have a Vertex 4" Rotating Table with a 80 mm chuck Mountet on a back plate with a morse taper to center the chuck

It is used on my Chester Champion 20V Mill table size 70 cm X 18 cm

I am very pleased with it

I also have all the dividing plates that goes with it

The only thing I did improve ( changed) with the rotary table is that I did extend the hight a little bit with a plate to make some clearence to the milltable as the inner part ( indexing part) of the handweel did touch the mill table when mounted in the middle of the Mill Table

I am going to save up and get the better 6" Vertex

Apologies in advance for a bit of a hi-jack, does anyone use a rotary table on a Unimat 3?

I've been looking at the 2.5" & 3" offerings of (dare I say it) RDG, plus Chronos!
Neither of them are very expensive tables at under £60, so not sure what quality will be like, then again, they're not going to get a lot of hard work as regards heavy cuts!

Would appreciate opinions on them!

John

Another point to consider: personally I'd find a Morse taper in the centre of a rotary table a right royal PITA. A parallel centre hole is much more useful when using mandrels and locating pegs for setting work central on the table.

had this problem also. I have to circumvent it by using a drawbolt + MT2 collet + ground arbor (that fits inside MT2 collet) + bushing to fit (if you need larger diameter stub than you can fit into MT2 collet). Sounds fiddly – it is, but gives pretty good repeated centering.

I also had to modify keys under the RT to index it straight into milling machine table. I have 1500 kg milling machine and 150 mm dia RT. RT is not very rigid for all the cuts. These cheap ones don't have very good bearings and design. But I usually get the work done.

Anyone fancy a ten inch table a friend has got for sale…one inch bore …built like a brick privvy…cant hardly lift it…mill had its own derrick to swing it on and off the table…might even come with free mill …..

Oi, bugger off and start your own thread…….

……haha only joking

I sent Chronos an email re the Vertes vs the Seba and response was very little difference in build quality

John,

Probably not what you are looking for, but:

I rather like Fig.1 here

Oi Petro1head, thought you'd done and decided to save up for a 6" Vertex …..

Well, seeing as it was a thread dedicated to rotary tables, thought I'd ask here first!

MichaelG, Nice rig that but too big for me to lug around, I just pack up my Uni 3 in a neat plastic toolbox! I've just sold all my unimat SL stuff anyway as my Uni 3 already has a milling pillar and head, so was looking at small rotary tables that would fit it, I've already bought the table and 'T' nuts for the topslide!

I'm getting a bit cheesed off with crossing out clock wheels with a saw and files!

The original Rotary Table for these Emco mills was approximately 6" for the table size. And I'd very much agree with Andrew about the internal MT isn't as useful as probably a staight bore would be. Even a 6" table can get very small very fast when your trying to fit tee nuts or studs, step blocks, washers and nuts just to hold the part in position. Vertex is ok and I have an older 6" model. Phase II are built a bit better and more accurate,.and the price reflects that. Personaly I wouldn't buy any Rotary Table without buying the dividing plates and the tailstock.Your thoughts and work may not agree with that. But If your using a rotary table? Then probably or at least sooner or later you'll be needing the extras. Building a replica of your lathes spindle nose that can be exactly centered and fixtured to the table is more than handy since you can then use the lathes faceplate or 4 jaw independant to also hold parts. Depending on the work requirements and our exact accuracy levels the lathes 3 jaw might be useful too.

But you can probably ignore the so called specification or "test" certificate that comes with the Vertex tables. It's pretty well worthless.as John Stevenson can verify I think. But the orginal Emco Rotary Tables aren't impossible to find either, and a lightly used well cared for Emco table will be a far better Rotary Table than anything that's usually sold today at the average M.E. prices. One of those would require an accurate 90 degree angle plate in addition to the Emco table since they were built as a horizontal table only.

John,

Some useful ideas here

The modified table looks more at home on the Unimat.

I know however if I go for the cheaper one I can get it ssooner.

has anyone here see these two side by side

[Howard LewisParticipant @howardlewis46836]

My R T is a Vertex HV6.

The slots for mounting bolts had to be extended to allow it to align with the tailstock when mounted on my Mill/Drill. It is aligned using a Square against the back edge of the table, and clamped down, using short studs fixed into Tee nuts..

Most often used vertical rather than horizontal. (i.e with the axis horizontal)

The clamps operate on the table rim, so it does not go off centre, and it appears to be reliable.

(I have used it several times for gear cutting, with dividing plates, without any obvious problems)

A 2MT/Myford adaptor allows larger work to be carried, and machined (eccentricically, if need be, using a small 4 jaw Chuck).

If it will fit onto your machine, my advice would be to buy one.

Like so many tools, once you have it, many more uses will present themselves.
