Combining a mill & a rotary table provides an order of
magnitude increase in machining capability. Shown here
 is a 4" rotary table which is perfectly sized for a micro-mill.
The rotary table can also be combined with a tilting angle
table to further increase its flexibility. Indicate the mill first,
then the rotary table. With a dial test indicator mounted
in the mill spindle, tram the inside surface of the rotary
table's center hole. Mounting a chuck or vise on the rotary
 table allows holding many differently sized pieces.
The 4-jawed chuck is especially versatile since it moves the
 part in 4 directions. Exchanging the same sized parts is
easy accomplished by loosening & tightening only 2 jaws.

Initial Alignment

Used a properly sized dowel to perform
the initial spindle to table alignment.

Tramming

Completed the rotary table
tram with a dial test indicator.

Part Setup Example

Milling operation to make a rocker tool post is shown.
Using a center finder to set the part's center of rotation.

The mill table x-axis is then moved the radius of the
semi-circular cut compensating for the cutter radius.
Shown is a 1/4" end mill cutting a 1-1/2" diameter curve.

Procedures & formulas for rotary table use
are described in Sherline's instructions.

Two disks aligned using 1/4" dowel pins in the 1/4" slots.
A washer spaces them above the table surface.

Milled four, 1/4" diameter 0.127" deep notches every 90 deg.
The small (right) notches are witness marks.

Rotary Table Alignment Bracket

Using a 2nd, 4-inch rotary table, made a bracket to hold
the gauge while centering work in the small 4-jaw.
I can quickly center the work piece while at the bench,
then transfer the 4-jaw to the 4th-axis of the CNC mill.
This is for an initial centering only; the final tramming
is performed after it has been transferred to the mill.

This is an 8mm stemmed gauge but the sleeve can be
removed to allow holding a 3/8-inch stemmed dial gauge.

Drilling eight, #7 holes every
45 deg for 1/4-20 hand tapping.

Making a round, chuck to rotary table adapter plate.

Vise Attachment

Rotary table with one-inch vise attached.
Having perpendicular slots allows the most two-way
adjustability. The hardened screwless vise has M4-0.7
pre-tapped holes on the bottom & built-in parallels.

Brackets

The rotary table is mounted onto a base plate for quick vise mounting.
The base plate also has (8) holes that align with the Taig mill table
T-slots to allow direct mounting using 10-32 cap-head bolts.

Miniature Toe-clamp Sets

The toe-clamp sets can be used for the Taig
Micro Mill & the Sherline 4-inch rotary table.

Rotary-table base-plate for the Taig table.

Right-angle bracket for the 4" rotary table.
Added an edge guide for easier set up.

Taig 4-jaw chuck mounted onto a Sherline tilt table.

Made an adapter plate to mount the
4" rotary table centered on the tilt table.
There is a 25 lb maximum weight limit for the rotary table.
