mill rotary table with chuck free sample
This is a modification of our 4″ Manual Rotary Table. This modification came about after requests from our laser engraving customers. They wanted a rotary table that had a larger through-hole to which they could mount our chucks.
This version of the Sherline rotary table has a Nickel-Teflon plating on the tabletop because it was designed to be used in an everyday production environment. This gives the table a rust-resistant surface that is hard and has added lubrication qualities.
The table is 2″ high and 4″ (100mm) in diameter. The main components have been machined from solid bar stock steel, and the complete unit weighs seven pounds. The table has been engraved with a laser, giving sharp and precise lines every 5°, numbered every 15°. These lines are calibrated with the 72-tooth worm gear that is driven by the handwheel or stepper motor. The handwheel is divided into 50 parts, making each line on the handwheel 1/10°. This allows a circle to be divided into 3600 increments without interpolation. Seventy-two revolutions of the handwheel rotate the table one revolution.
NOTE: You can have your manual rotary table upgraded to CNC-ready, but this is done as a factory-only replacement. You will need to ship your manual rotary table back to our factory for the conversion.
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.
Why do we have to do that? Quite simply, you have forbidden us to watch Your steps on our site with Google Analytics. That sounds dramatically to You, we know. But look at it: we do not even know who YOU are, we just see that SOMEONE looks at our pages, how he/she does that, how long this SOMEONE lingers on the respective pages, etc. We do not know who You are, whether You are male or female, how old You are, how Your weight is - no idea.

The chuck is a specialized clamp-type used to hold objects with radial symmetry like drills or perforators. By fixing rotary table chuck on the front part of your rotary tools, you will be able to fix various tools and parts such as screws, nuts, drills, and cutters. Having a chuck in your toolkit will allow you to finish your jobs quickly thanks to its versatility and practicality.
rotary table chuck can also be used to fix a workpiece. This small tool facilitates the transition between different activities, like going from drilling to screwing. Furthermore, you can also use it as a rotating element in drawn glass manufacturing. Some chucks are composed of retractable keys, which give you more freedom in your work and improved performance.
You will find various types of wholesale rotary table chuck in our online collection. The jawed chucks are one of the popular types, and they often have three jaws. They are ideal for gripping circular or hexagonal cross-sections. The four-jawed chucks are also available, and they are generally suitable for gripping square or octagonal material.
We also have other modern types of rotary table chuck. For example, the collet chuck is perfect for small-sized bar stocks, and you can operate it by hand or by power. Another modern type is the magnetic chuck, which is perfect for holding ferromagnetic workpieces. Without forgetting to mention the vacuum chucks that you can use to hold non-ferrous materials such as plastic, aluminum, and stone.
With this extension, your CNC milling machine gets the 4th axis. That allows you, for example, to mill round parts or create engravings on rounded surfaces.
This rotary axis is made to order for us by a German precision mechanic. In this price segment, this rotation axis for CNC milling machines is unrivalled in Europe!
There are many rotary tables on the market. If possible, they have to be inexpensive. You can get a lot of them! Usefulness? That is where the wheat is separated from the chaff. For example, there are many CNC turntables with the cheapest belt transmission. The disadvantages are obvious: slippage due to the belt. If not in the belt drive itself, then on the load or idle side of the belt. Perhaps useful for engraving work. For milling, however, usually not or limited in the choice of material (aluminium 3D milling not possible).
Made with the highest quality made in Germany with high-precision, a ground worm drive and holding torque of over 20Nm using only high-quality components. That is the reason you can machine round parts with the lowest tolerances.
That means you can use the CNC router for 3D 360° machining in almost all materials. Even round engravings on Plexiglas are possible without any problems with this CNC accessory. That means for our CNC machine users: Round surface milling of plastic parts, wooden parts, aluminium parts or round parts made of brass, as well as engravings of all kinds.
