hv6 rotary table made in china

Our Tables are made of high density Meehanite and use "HEIDENHAIN" electronic equipment to inspect angle to assure the excellent quality and durableness.

Worm is hardened and ground. The ratio is 90:1. The work table is graduateda full 360° so that one turn of the handle moves the table through 4°. Micro collar is graduated in steps of 1"min. And vernier scale makes settings down to 10 seconds possible.

These Rotary Tables are popular for their excellent perfor-mance, practical design and reasonable cost. They are widely used for circular cutting work, angle setting, boring, spot-facing and similar work.

A rotary table is a precision work positioning device used in metalworking. It enables the operator to drill or cut work at exact intervals around a fixed (usually horizontal or vertical) axis. Some rotary tables allow the use of index plates for indexing operations, and some can also be fitted with dividing plates that enable regular work positioning at divisions for which indexing plates are not available.

Rotary table in market mainly includes 4 kinds of mechanism that is worm gear, roller cam, DD driver and harmonic structure. The following is the introduction:

1. worm gear: it’s one of  the most popular structrue in NC rotary table  because of its irreversibility and costs.The worm is generally made of bronze, but the wear resistance is poor. In order to improve the service life, some manufacturers use the alloy steel.

3.DD motor: it’s the most efficient rotary table with the highest precision. It has the highest precision because it has no mechanical structure, which is directly driven by motor , no reducer. It has high technical difficulty and high price. It is generally used for five axis machine tools.

Having purchased a 6" rotary table from Chronos, I hope I am permitted to say this. The Chronos table was very poorly finished and the engraving was barely visible through the corrosion. I think this was a returned item.. The cranking handle was fixed on its spindle. It went back. Purchased a 6" one from Warco and what a difference. Beautifully finished smooth as silk good legible engraving and finish with a fully rotating handle. Backlash adjusted to virtually nil. Good job Warco!

I too purchased a Warco HV6 rotary table with dividing plates etc. As with most Chinese imports it needed a strip down and clean. Apart from the a small adjustment with one of the clamping plates it has served me well. The only annoying aspect are the tee slots not in the vertical and horizontal position when the table was set to 0 degrees.

There is no doubt about the quality of the Warco HV6 rotary table. It was from a newly delivered batch and does not need dismantling to clean etc. The design is quite different from what was supposed to be a Soba brand from Chronos. which did not have a Soba marking. The Warco was superior in all respects and looks almost exactly like a Vertex even down to the black crackle finish. I rest my case. I did note that the Vertex had just three slots as opposed to four on the Warco.

However, modernising production isn"t complete yet. Around the world there are plenty of businesses who are behind the curve. It"s still possible to find excessively cheap stuff being made by low-productivity methods. A small foundry with low labour costs and a few basic machine tools might be scratching out a living by knocking out HV6 clones. Goods made this way can vary enormously from excellent to junk, even from the same factory. But these guys are batting on a sticky wicket. An up-to-date factory that wants the business can produce the same item better and at lower cost. It may not be worth their while.

Model Engineers are at a disadvantage because the market is small and their isn"t much competition driving improvement. In comparison, almost every home wants a DIY electric drill, so there"s high demand for reasonable kit. Better but affordable electric drills are profitable because they sell by the million. DIY tools are excellent value because the rubbish has mostly been forced out.

As mentioned above a lot of old first generation CNC machines may have been exported and these may be what is being used to build the lower budget products. Top of the range CNC gets used when the customer is willing to pay the top range price for their rotary table that is why some 6" ones cost a couple of thousand pounds compared to £150-200 for the run of the mill hobby ones.

Some informative replies to the points I raised, so thanks to you all for adding to my education. But just before I let this thread go, please let me say that I bought a 6" British made Sharp rotary table from Mill Hill Supplies many years ago. It has never been used because shortly afterwards I acquired what immediately looked to be a far superior Vertex model for a very reasonable price at an exhibition trader"s stand and this was at a time when the air was full of derogatory comments about the far-eastern products which were coming on to the market. I assumed even then that this was because the much higher quality "Chinese" product had been made using modern production methods designed to supply the world market whilst at the time I think a lot of people would have said that British made Sharp was better because it had been made using traditional skills by a small engineering company in the north of England. I apologise if this comment disappoints those who still cling the rose-tinted view that British was best.
