hoffman rotary table made in china

Manual precision rotary table with compact and space saving design. The high rigidity allows the use for machine tools as well as for measuring applications.

Additional direct indexing plate for the indexing plate device for all divisions up to 100 and higher ones, many up to 400, with included adjusting table.

I have the 8” with plates. Don’t use the plates often but easy to fit, otherwise they normally they get in the way but ok when used. I would have liked it to work in vertical mode, but I have a good vertex dividing head so no problem here. it’s certainly is a brilliant bit of kit. The thrust bearing under the table is huge. It’s smooth and accurate. Best bit of kit I have. Same t slots as a myford, but parallel 20 mm bore centre. So no mounting stubby morse tapers but I now have a range of dedicated centres..

I am looking for a Soba 6" rotary table and a chuck adapter plate. Everywhere seem to be out of stock. Does anyone have a secret source or can offer advise on a suitable alternate that is in stock?

I"d look for second hand, sadly there are loads of engineering companies out there selling off top quality equipment at knock down prices. I don"t have a Soba rotary table but their products are, in my opinion at best average. Good luck with your quest though.

If you can afford the Vertex, it is made to a higher standard than Soba. I have a 6" Soba, bought privately, but in new condition, and the first thing I had to do was ditch the central needle roller bearing and turn up an aluminium bush. This was because I noticed a large ammount of radial play when the table was unlocked. I did not think 0.010" movement was reasonable, and who needs a needle roller bearing for the speeds at which a rotary table achieves. Now it works ok. As the table has four tee slots, a four jaw independent with front mounting is easy to fit. I have drilled and tapped holes for a 5" front mount Pratt Burnerd three jaw scroll chuck. This requires some thought, I made the mistake of drilling one of the holes into the drilling for lubrication, and had to re align all three. Now the holes are in the right place, fitting the chuck is easy, and with a test bar in the central Morse taper, and the chuck jaws lightly clamped on it before the screws are tightened, the chuck is centralised to about 0.002" tir which is good enough for my purposes. Having some short grub screws to put in the holes when the chuck is not fitted keeps the muck out of the works.

ps. I note that RDG Tools show a 6" "no brand" 3 tee slot rotary table here Apart from the 3 rather than 4 tee slots, it looks superficially like my Vertex unit.

On the assumption that the graduation lines are of equal width on both machines, an error in rotating the handwheel, of, just for the sake of argument, 1 degree will result in an error of 0.01111111 degrees in the table position.

A sip rotary table used in jig boring will have optical scales, but our scales are good enough for most jobs. The downside of a 90:1 worm ratio is the number of turns required to get anywhere. I prefer not to disengage the worm.

Handwheel markings and Verniers or Division Plates are merely different forms of graduation. What matters in terms of precision is the error, or lack of it, in the position of the Table. So the higher ratio results in less error (greater precision ) in Table position for a given error in the input.

when I was young, strong, healthy, and thought nothing of lifting it, a 10" H & V was my first choice. I still think it was a good choice for the work I mostly do, and this is where you may decide to compromise. If you do small work, an 8" table is much lighter and more convenient to set up. Stood vertical, it interferes less with the spindle to reach center. I don"t think a 6" is a good choice unless you know you will only be working miniature stuff. You use a considerable percentage of a small table just for set ups and hold down clamps on a lot of work, and a small table does not leave much room.

I like 90:1 gear ratio for circular milling, which is presumably your primary interest with a rotary table. My 10" table is 90:1, and that is a pretty good ratio for milling diameters (hand cranking) out to 12" or so. My 20" table is also only 90:1, and out near or past the rim (I do one part at 32" diameter) that always seems _very_ coarse.

If most of your work is small, round to begin with, and will actually be dividing work, where you index the table, lock it, and then drill a hole or mill a slot with the machine axis drive, you might find a dividing head more useful. For instance, I"ve made gears on a vertical rotary table, and in a spin index. On the table, you need an insert collet chuck or other arrangement in the center hole to get the work out far enough to clear the cutter. It"s a lot more convenient on a dividing head. OTOH, I don"t find it fun or convenient to do much circular milling on a dividing head if the work diameter is much over a few inches.
