using a rotary table on a milling machine brands
Years ago, before I learned CNC, I owned a Phase II 8″ horizontal/vertical rotary table that I purchased from Kap Pullen’s Getmachinetools.com store. He has them at a good price, BTW, and he’s a darned nice fellow to deal with as well as being a frequent HSM contributor. Anyway, its a nice little table, but I hadn’t done a whole lot with it for quite a while after purchasing it. As is so often the case, one day, a project landed on my doorstep and I was glad to have it.
Before I could get started, however, I had to make some accessories for it. Basically, I needed some T-Nuts to fit the table, as well as a little fixture that makes it easy to hold a plate up off the table through a hole in the center so you can machine it. The latter, what I call a “plate machining fixture”, was inspired by something similar I saw the Widgitmaster of CNCZone fame using to make Dremel clamps for his mini-router:
The Plate Maching Fixture and 3 Homemade T-Nuts. T-Nuts are easy to make: square a block to the proper dimensions, mill the side reliefs, drill, and tap. These are much smaller than the mill’s Bridgeport standard T-slots, so I made them myself and I’m using 1/4-20 bolts with them. They’re made of mild steel.
I turned the round spigot using the 4-jaw on the lathe. I’m making the fixture out of MIC-6 aluminum plate, which is pre-ground very flat on the sides. This is a 5 inch by 3 inch piece. I’ve clamped it to the rotab using my T-nuts and the regular mill clamps and step blocks. It is sitting on parallels to make sure I don’t cut into the table. You can also see how I’ve clamped the rotary table to the mill table using a big cast iron V-block I have. You can never have to many blocks with precision faces hanging around!
Having a 4-jaw chuck on your rotary table is mighty handy! Because it’s a 4-jaw, you can dial in the workpiece by adjusting the jaws until it is perfectly concentric with the table’s axis of rotation. The best way is to make an adapter plate that attaches to the back of the chuck in the same way that your lathe does so you can exchange lathe tooling with the rotab. Here is an example:
For the example, the chuck is threaded onto the adaptor plate, and then the holes in the adapter plate’s flange are used to bolt down to T-nuts on the table.
In my case, I bought a 4-jaw from Shars brand new, and simply drilled some through-holes in the chuck to mount to the table directly without an adapter plate:
First, you want to make sure your part is properly centered on the table. To do that, I clamp the table down on the mill table (no special place is needed), put my Indicol indicator holder on the mill spindle, and find some round feature on the part to indicate on. For example, on the plate milling fixture above, indicate on the round boss, or on the center hole. Spin the table and bump the part in until spinning the table doesn’t move the indicator.
Second, locate the center of rotation directly under the mill spindle. You can simply use the X and Y table handwheels to do this. Use that Indicol to indicate off of a circular feature you want centered under the spindle. Turn the indicol around on the spindle and adjust the handwheels until the indicator stays put relative to the spindle position. A Blake Coaxial indicator will make this last even simpler.
When you’re rounding partially by cranking a part around on the rotary table, it’s really easy to go a little too far and screw things up. The answer is to drill the end points to make the exact stopping point on the rotab a lot less sensitive:
Centering with a Blake indicator is really fast, but what if you don’t have a Blake, or worse, what if your mill is too small to accomodate one? Here is a nice solution I found on a German site. This fellow has made an ER collect fixture for his rotary table, and has taken care that when installed on the table, the axis of the collet is aligned with the table’s axis. He can then place a dowel or other straight pin in the collet and line up until it will go into a similarly sized collet on the spindle. Nice trick! It’s similar to how Widgitmaster showed me to align a drill chuck on a QCTP to the lathe centerline with a dowel pin held in the lathe chuck.

Standard Rotary Tables. The AR Series is TJR’s standard 4th axis pneumatic brake rotary table. It is offered in both a Right hand motor mounting and Left hand motor mounting option. The HR Series is TJR’s standard hydraulic brake 4th axis rotary table.
CNC Indexing & Feeding Technologies offers a wide range of TJR rotary tables. However, many are unclear about what rotary tables can do for their business, as well as how they work in CNC machining. First, let’s consider the basics about a rotary table and how it works in the machining and manufacturing processes.
Milling and other industrial processes require cutting and shaping, usually with a high degree of precision. This creates the need for computer-guided systems that can create workpieces, prototypes or tools for companies on demand. The process is expedited, reducing or removing the need for large assembly line staff or other hand crafters.
In many cases, the work pieces created through CNC machining would be impossible without computer assistance. The code used to communicate between the CNC machine and computer software is specialized. Older machines, or manual machines, used hard wired controllers. However, new CNC machines rely on modern devices like CDs, USB drives, networks and so on.
A lathe or milling machine requires its own set of parts to work sufficiently. For example, an indexing head is needed to allow circular shaping. The indexing element allows the piece to be rotated at an angle or even divided into sections.
A rotary table can tilt and rotate. The table makes use of the indexing head in order to cut according to a specific technique. This makes it possible for the machine to create a workpiece with complete flexibility in rotation and angling.
A rotary table can help to create arcs and circles, an important process in part or tool fabrication. Tools can be specially made, such as car parts, machine parts, and many other objects.
The CNC process lets companies make straight cuts even with multiple angles and to cut small objects into even smaller parts. CNC rotary tables can also help in the processes of cutting gears, drilling or cutting holes.
The table can also be used along with a dividing head and index plate, to further concentrate the shaping. Tables are also used to hold certain parts for superior milling techniques.
Adding rotary tables will improve your capacity to produce the parts you want and increase profits. This brings us to the primary advantage of CNC rotary tables: less time and greater accuracy in cutting.
Companies are often outsourced to create work pieces for larger brands. However, some companies simply create their own prototypes, tools or work pieces with their own facility for machining. There are also contract shops, mechanic shops, electronics companies, inventors, engineering, and retail companies.
Most companies save costs by scaling their needs with small productions. In many cases, they may only have one facility or work with one type of part. The key is not to create “anything” but to specialize in objects created so the process can be streamlined.
The benefits of using cnc rotary tables include consistency, faster production and increased capacity. Products and work pieces assembled through CNC systems are more reliable than products created manually or through other methods. The process is identical each and every time, so consistency can be guaranteed. This is critical for a company trying to ensure safety protocol.
Flexibility is another advantage, as the systems are programmable. These systems are designed to minimize downtime in between their running processes, offering greater flexibility.
The capacity of complexity of product is another benefit. Complex motions are made simpler by CNC rotary tables, making them more affordable to produce.
Naturally, such an intricate process cannot be unsupervised, since efficiency depends on optimal performance. A supervisor must oversee a rotary table operating with CNC controls to ensure the machine and software are configured correctly.
This involves setting the system up, installing the software, and watching over the production. If something goes wrong, the software must be fixed and the machine repaired. Machines are not constantly running, but must be evaluated and cleaned regularly, ensuring that they will be mostly self-sufficient.
We offer a wide variety of rotary tables to meet all of your needs. This includes standard rotary tables with full rotating axis capabilities, and vertical and horizontal mounting positions.
We also offer large rotary tables with hydraulic brake systems, which allow higher clamping torques. You can also find assistance with smaller rear mount rotary tables or tilt rotary tables.
Horizontal rotary tables are specially made for horizontal mounting and carrying a much heavier weight. Horizontal index tables are available, whether in manual or CNC index tables style. Finally, there are face gear rotary tables and rotary table accessories, ideal for projects that need higher degrees of accuracy.
Remember that quality production is synonymous with efficiency and accuracy. Product producers must have the right equipment operating at full capacity in order to guarantee consistency.
CNC Indexing & Feeding Technologies can help you find the machine tool accessories you need to meet your production demands. This includes simple rotating feature, larger work pieces, vertical and horizontal applications, or even 4 or 5 axis work. With TJR rotary tables, you can improve your cycle and process time, reduce your down time and increase your profits.
