Warco HV6 rotary table

[Howard LewisParticipant @howardlewis46836]

At one time, my employers found that it was possible to buy a fully machined component from China for less than the cost of a raw casting in UK.

BUT, later a batch of another much larger and more complex casting arrived incorrectly machined. The bad news was that here was another shipload en route, and it would be six weeks before correct material could be shipped.

So, have a factory with around two thousand employees twiddling their thumbs, rather than being bproductive?

Shows the need for constant vigilance and supervision,

In my book, there is a lot to be said for self sufficiency where the minimum of material or utilities are under the control of someone abroad.

But it takes a long time to recover a situation like that.

And before anyone asks, my lathe is a far eastern product, but was specified by a Toolmaker, and seems to be, generally, of good or acceptable quality

Apologies for hijacking the thread, though it is relevant. Especially when it's the Warco 10% off weekend!

I have a Sieg SX3 mill and wondered:

1) Is a 6" rotary table recommended or would you recommend a 4"

2) How does the Warco HV6 (Vertex style?) rotary table compare to the equivalent ArcEuro one, which is significantly more expensive? JasonB – I understand you use the ArcEuro one

3) Would the hole spacings allow the HV6 to be mounted vertically on the SX3? (Does anyone have the minimum and maximum hole centres for vertical mounting?)

Many thanks,

Mike

An aside now, but my Vertex HV6 came from Chronos, and has four Tee slots.

So then three slot ones have been cost reduced

"Our policy is one of continuous improvement"

Of what? Our Profit margins?

And before anyone starts sending flak, I have worked on Cost Analysis, and brought about cost reductions, so have seen both sides of the coin!

On monday I am buying a Vertex VA4 milling vice 20kg(Taiwan) for double the price of a similar looking chinese one(I think 19Kg), so I hope its ok.

6" for the SX3 and X3 size machines.

The 72:1 gearing of the arc one seems to suit common dividing using the handwheel more than a 90:1. Being able to set the 360deg ring on the ARC one in any position is a useful feature. Grub screws are best replaced and the spindle adjusting lockring could be better. Being a right hand mount when in vertical mode you have to watch the quill handles.

Can't comment on the Warco as I also have a 6" Soba which has also served me well, but if slots are the same spacing then I use 1 slot and one clamp when in vertical mode.

I like 4 slots as you can mount your vice easily on the rotary table

Bought a 4" rotary table last spring, from a brandless Indian source (ebay). Well I paid for that, as it was so non accurate that I decided 6 month later to go for another one. I finally bought a Warco 4" model, I kept the 80mm self centering chuck which came with the indian one, as this was ok. With this combination I am now happy, but I threw about 60£ out of the window…

As in my starting posting, see first posting in this thread, I have the 6" Warco table and am delighted with it. Great finish and when adjusted, next to no play. Really smooth action.

The 6" Soba that I bought needed a little work to make it run properly. I soon noticed that the table bearing was very loose, allowing about 0.010" radial movement which really affected the accuracy. I replaced the needle roller bearing with a turned up aluminium bush which has 0.0005" clearance dry and none with lubrication. At the speed the RT turns, it will last forever.
