TV6 Rotary Table Kit
For Vertex style 6" tables
(See Links page for links to various table suppliers)
Designed for the Vertex HV-6 style rotary tables our TV6 kit allows you to easily convert this readily available table into an NC axis to use on your X3 or any other suitably sized mill. The table retains its ability for use in both horizontal and vertical orientations. The design of the kit and its HDPE cover matches perfectly with our MX3 Mill kits.
Basic turning (like a lathe)
Engraving around cylindrical objects
Motor armature rewinding (nice and slow!!)
Can be used with any mill
Matches our MX3 kit beautifully
Easy to fit
Homing Switch (adjustable position)
We offer the kit in 4 Models ...
H Base Hardware kit. All hardware, pulleys & timing belt, home switch.
HM As per H plus motor and cable.
HMA As per HM plus AB403-2m Axis Card
HMAT As per HMA plus Vertex 6" Rotary Table
HV-6 TABLE ONLY INCLUDED IN THE HMAT MODEL
It will take the average handy-person approximately 40 minutes to convert a Vertex HV-6 rotary table to NC. Included is a 28 page manual which has step by step instructions and photographs to guide you through the installation. Fitting the kit is so simple we have even had customers do it without reading the manual!
No special equipment is needed to complete the installation other than a drill and drill bit of appropriate size.
A spare axis output is required on your controller. For customers who already have one of our IC3A 3 axis controllers (eg as sold with in the MX3HMC kit) all that is required is another AB403-M axis card.
For customers with a different controller you need to ensure that you can set the axis channel to 2.8 amp. Any bipolar controller should be capable of running this kit.
All TV6 kits include a micro switch homing option which requires one hole to be drilled in the table side for the homing switch cable to exit. The kit is otherwise non invasive and can easily be removed at a later stage if no longer required - leaving nothing but a single 4.5mm hole in the base. Fitting of the homing switch is optional and is not required for the table to work.
A discount is automatically applied to TV6 kits ordered with any of our main line kits (on the same order).
Obtaining a Table
We can supply the Vertex table (HMAT model only) however for most customers it is preferable to pick up a table from your local supplier due to the weight of the unit (approx 12Kg for the table plus another 2Kg for the kit).
It is worth noting that we have seen the same rotary table offered under several different brand names ... most likely if your table (or one you are thinking of getting) looks identical to the Vertex it probably is the same unit just with a different name.
Rotational SpeedRotational speed will depend on how you set up the final adjustments - a very tight system may only run at 1 rev per 15 seconds. Our prototype has been set up to have virtually no backlash detectable by eye/hand and is capable of running at speeds up to 1 rev per 5.5 seconds although to allow some overhead we usually run it at 1 rev per 8 seconds. See our videos page to get a better idea of running speeds.
There are several reasons why we employ timing belts and pulleys...
One of our design criteria was to keep it small - low profile. By using timing belts we can tuck the motor safely back in behind everything - direct coupling means that the motor has to protrude straight out from the worm drive shaft which means that more free air space is required around the table.
Direct coupling to the end of the worm drive shaft is also far more prone to damage as any pressure applied to the motor will lever against couplings and mounts. Imagine the leverage applied to the mount points if somebody was to lean on the motor or a heavy piece of stock was balanced or dropped on it!
Another reason for using timing belts is that common stepper motors only have standard roller bearings which are designed for radial loads - not axial ... a misaligned direct coupling could result in power loss and premature bearing failure.
In our application of timing belts the load is entirely radial which means that the bearings are handling the pressure in a manner they are specifically designed for.
Timing belts are also specifically designed for applications such as this. They have internal radial reinforcing (usually fibreglass or carbon fibre) which is there specifically to eliminate stretch - so contrary to popular belief (and rumour by the direct drive fraternity) they will not cause backlash. Their trapezoid teeth and corresponding pulley grooves provide a very positive and positionally accurate lock.
Timing belts are also cost effective, low noise, easy to fit, no slip and readily available.
The standard configuration uses the micro switch in the normally closed mode however if your controller requires normally open mode then anybody capable of using a soldering iron can change over the connections on the switch. Most software (eg Mach3, TurboCNC) allows you to configure the home switch either way - normally closed or normally open.
