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 plate is smaller then the rotary table base allowing it to rest on top
of the vise jaws. 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.
