sherline rotary table supplier

Sherline offers one of the finest small rotary tables on the market. It is available in manual or stepper motor drive modes. It can even be purchased with its one controller to be used as a programmable indexer. Below are links to the pages on the various versions of the Sherline 4″ rotary table. The table is driven by a worm gear with a 72:1 ratio making each turn of the handwheel equal to 5°. Fifty laser engraved handwheel marks indicate positions 1/10 of a degree apart. A 90° fixture is available to position the table in a vertical position. Our P/N 3750 Tilting Angle Table is also available for positioning at any angle from 0° to 90°.

Sherline’s rotary table is one of the most popular accessories in the tool line. Its popularity extends from the home shop to the professional machine shop due to its compact size, solid construction, and long-lasting accuracy. The handwheel is calibrated in 1/10° increments with marks every 5° around the table’s periphery. Included is a set of hold-down clamps, T-nuts, and a threaded center fixture for attaching Sherline chucks with a 3/4-16 center thread. Read more about the Sherline manual rotary table.

P/N 3700-CNC 4″ CNC-Ready rotary table with stepper motor mount: In place of the manual handwheel, a NEMA 23 stepper motor mount is attached, allowing use of the rotary table as a 4th axis on Sherline CNC mills or for whatever CNC application a customer may have where a small but accurate rotary table is needed. Read more about the Sherline CNC-Ready rotary table.

P/N 8730 4″ CNC rotary table with stepper motor mount and NEMA 23 stepper motor: This takes the above rotary table one step further with the inclusion of Sherline’s own NEMA 23 stepper motor already attached to the rotary table and including a 5-pin plug that connects directly to the Sherline 8760 4-axis driver box. Read more about the Sherline CNC rotary table with stepper motor.

Sherline offers the answer to your small rotary indexer needs by providing a programmable control box with its own power supply and driver for running the rotary table. Inputs can be entered by either degrees (to 3 decimal points) or by divisions of a circle (up to 999 divisions). Also programmable are the direction of rotation, the speed of rotation and backlash compensation. In the PROGRAM mode, two different programs of up to 40 blocks each can be entered that control rotation speed, direction and degrees or divisions plus the option to continue or pause at the end of each block. Read more about the Sherline programmable rotary indexer.

For the laser marking industry, Sherline now offers several accessories including three sizes of tooling plates designed for holding parts during scanning. Read more about the Sherline laser scanning plates.

The rotary table also is available with larger, 15/32″ through hole to which you cab mount our chucks. This modification came about after requests from our laser engraving customers. The larger through hole allows for larger stock to be held. It also has a Nickel-Teflon plating on it because it was designed to be used in an every-day production environment. This gives the table a rust resistant surface that is hard and has added lubrication qualities.

Sherline has taken their accurate and reliable 4″ rotary table into the 21st century with the addition of Computer Numeric Control. Clock-makers or anyone with a need to cut gears or other complicated radially symmetrical patterns will find this accessory takes all the headaches out of repetitive indexing operations.

The rotary table comes with clamps and T-nuts for attaching it to the T-slots of a Sherline mill table. In addition, there are two options available for mounting the table in the vertical position or at other angles:

Right-Angle Attachment—This plate holds the table in the vertical position with a center height of 2.7″. A right-angle tailstock is also available to support long stock held on center in the rotary table.

Tilting-Angle Table—This table holds the rotary table and can be fixed at any angle from 0° to 90°. In the 90° position, the rotary table center is also at the 2.7″ height, which allows the right-angle tailstock to be used with it.

After entering the number of steps per revolution (or the number of degrees per step) on a simple numeric keypad, the table advances quickly and precisely to the next position at the touch of a single advance key. If an error is made, previous positions can be accurately recalled by hitting another button. Basic resolution is 28,800 steps per revolution, ±0.006° per step. This allows the accurate machining of items like gears with odd numbers of teeth. Computations are made internally to a high degree of accuracy to avoid cumulative errors.

At Sherline, we manufacture the world"s most complete line of precision milling machines, lathes, and chucker lathes (also known as Mini or Micro Mills and Lathes). We manufacture both manual and CNC machines for benchtop or tabletop-size workspaces, along with a full line of accessories to support these machines.

A rotary table used in conjunction with a mill allows a machinist to produce virtually any part they can design. Sherline’s rotary table is a precision piece of equipment that has been designed to work with their vertical milling machines. However, it can be used on any mill whenever the small 4-inch size would be an advantage. The only limits are size, not complexity.

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. 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.

The rotary tables can hold more weight when they are not under a continuous load. Click on the Video tab above to see examples of different weights and uses for our rotary tables.

The table T-slots are identical to those used on the Sherline mill and lathe, making the vast line of Sherline tooling available for use with this product. Two hold-down clamps and T-nuts are provided with the table. Also included is an adapter that allows Sherline’s 3- and 4-jaw chucks to be screwed directly to the rotary table. An optional right-angle attachment is available (P/N 3701) to mount the table in the vertical position to increase its versatility further. With the table mounted vertically, an optional adjustable right-angle tailstock (P/N 3702) can be mounted to the mill table. It is used to support and stabilize the other end of long work held in a chuck or otherwise attached to the rotary table.

Sherline has taken its P/N 3700 manual 4″ rotary table and applied a stepper motor mount with dampened coupling in place of the handwheel. The mount accepts a NEMA #23 frame-size stepper motor for CNC control. This allows the table to be used as a 4th axis with CNC systems that have the capability to drive a rotary axis.

The CNC rotary controller is a stand-alone unit. You get everything you need to make complex indexing jobs easy. In addition, the unit can be connected to an existing CNC control to act in conjunction with that system. An input signal triggers the programmed function. When it is complete, it signals back to continue the program. The unit can also be “daisy-chained” with other units to trigger sequential actions. As with all Sherline accessories, complete instructions are included.

The rotary table can also be “daisy-chained” with Sherline’s linear controller to achieve combinations of rotary and linear movement in sequence. This makes it easy to set up for relatively sophisticated operations like cutting gears without having to know anything about CNC programming beyond what is entered from these simple keypads.

On our rotary tables, we finish-grind the tabletop as the last grinding operation for the entire assembly. This means that the overall thickness variation of the assembly is less than (.001″, .0254mm). If you buy this rotary tabletop as a replacement part, the thickness variation of the rotary tabletop (in its machined state) will be .001″ or less. However, the assembled thickness variation may exceed this amount because it is not being finish-ground as an assembly.

A ghost view of the rotary table drawn in SolidEdge® by John Costello shows the internal mechanism so you can see how the worm gear drives the table. Ball bearings are shown in dark blue.

The rotary table has a unique table locking mechanism that is positive and does not move the table as it is locked. To maintain accuracy and frictionless movements, ball bearings are used. Worm gears are factory greased and the drives sealed to keep out chips and dirt. An oiler is easily accessible to facilitate lubrication of the table. The appearance is instrument quality with a black oxide base, precision ground finishes, and laser engraved markings.

As with all Sherline tools, the illustrated instructions are very useful. The 8-page manual covers the basics of rotary table use and takes the user through a typical project.

Any machinist desiring to take his capabilities to the ultimate levels should consider purchasing and learning to use a rotary table. The Sherline rotary table is an extremely precise and well-built piece of equipment that is sized to fit with our product line. It can also be useful on larger equipment when its compact size is called for.

The rotary table is also available with a stepper motor mount attached ready for the application of a stepper motor and CNC controls. See P/N 3700-CNC.

NOTE: Because components of the table are ground as a set during production, the P/N 3700 rotary table cannot be upgraded to the P/N 3700-CNC version later on. A new rotary table with stepper motor worm housing must be purchased.

A rotary table is a really nice accessory to have for your mill, but one that you can delay purchasing for a while until you master the basic milling operations. The rotary table is driven by a worm-gear and is accurately calibrated in degrees and fractions of a degree.

Finding a rotary table of the right size for the mini-mill has been a lille problematic. 8-inch tables are really much too big. Even a 6-inch is pushing the limits. I have one from Grizzly. It is well made and works well, but mounting it to the table was a little bit of a challenge.

Sherline offers a very nice 4-inch model, and more recently LittleMachineShop.com has listed a 4-inch model as well. These are very nice, but a little smaller than I would like. In my view, a 5-inch model would be ideal, but I don’t know of one in that size.

The first rotary table I purchased was made in India and was of really poor quality. I returned it to the vendor for a refund. Unfortunately, the return shipping on a heavy object like this is not cheap, so be careful what you buy!

Sherline makes a beautifully finished 4″ rotary table which I got to see first hand at Cabin Fever 2001. I was very impressed by the high quality of this item, but It was a little small for my needs.

The table I currently use is a Grizzly G1049 6-inch model. As of 03/02 it sells for $199 plus shipping. It is well-made, and I have been very satisfied with it, although it is a little large for the mini-lathe as you will see in the photos below.

After cleaning off the packing grease with kerosene, a painbrush and a rag, I mounted it on the mini-mill table using 3/8″ carriage bolts that I also use for my 3 1/2″ Grizzly milling vise. The center hole is a #2 Morse taper.

The RT is really a little oversize for the mini-mill, but still provides enough clearance to be practical. I did not feel that the weight was beyond the capabilities of the mini-mill table.

Here’s a picture showing the table with a 12″ rule and a 1/2″ mill in an end mill adaptor. Mounting the mill in a collet would provide another 2″ or so of working room. The head is at the top of the column. Also shown is the 3″ chuck from the 7×10 mini lathe. As you can see, there is adequate clearance for most operations.

The casting has mounting lugs for both horizontal or vertical mounting. This makes it potentially much more flexlible, but the table of the mini mill is small compared to the RT which makes mounting the rotary table in the vertical orientation a little tricky.

One problem is that the lower edge of the handwheel for the RT is lower than the base of the RT, so it must be positioned off the edge of the table. If the RT is positioned perpendicular to the X-axis, the mounting holes in the RT are outside the limits of the T-slots in the mill table.

For the price, I was pretty impressed by the quality of the table. I would rate it somewhat lower in quality than the Sherline 4″, but much better than the Victor 6″.

The handwheel is satin-finish steel with cleanly etched divisions. Each full rotation of the handwheel rotates the table by 4 degrees. A brochure included with the RT illustrates an indexing plate accessory which can apparently be attached to the RT, but I’m not sure whether or not Grizzly sells this accessory.

An eccentric cam between the handwheel and the table permits you adjust the meshing of the worm-screw to minimize backlash. A screw with a T-handle locks the cam in place once it is set.

Here’s a nice little 4″ imported rotary table offered by LMS for $134.95. They offer several other models, including the Sherline 4″. I don’t have any first-hand experience with this one, so I can’t really comment on quality or capabilities.
