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.
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.
Taig Mill table
cross section
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.
