CNC-READY SHERLINE LATHES AND MILLS
FIGURE 77—Any Sherline lathe or mill can be ordered
“CNC-ready,” and existing machines can be easily
converted to have stepper motors drive the leadscrews.
Shown here is a cutaway of a stepper motor mount with
two preloaded ball bearings and coupler.
Sherline now offers the stepper motor mounts and
couplings needed to turn any Sherline lathe or mill into a
computer-controlled machine. Several aftermarket
companies offer complete CNC machines based on
Sherline tools, but if you can come up with the software
portion of the system, you can now build up your own
stepper motor-equipped machine from Sherline
components. An exploded view of a typical stepper motor
mount and coupling is shown on page 41. A list of dealers
selling Sherline CNC packages is available on Sherline’s
web site at www.sherline.com/cncdlrs.htm or by calling
Sherline and requesting a CNC dealer list.
UPGRADING 5000/5400-SERIES MILL COLUMNS
TO 8-DIRECTION CAPABILITY
Any existing Sherline mill can be upgraded to 8-direction
capacity with the addition of a 2000-series column
conversion. The rectangular column base is replaced by
the round column, ram and rotating collar of the 2000-
series 8-direction mill. A base adapter offsets the column
to the rear to make up for the additional mechanism so
that no Y-axis travel is lost. (See Figure 78, next page.)

computer control to operations like cutting gears.
CNC ROTARY INDEXER (P/N 8700)
Based on the 4" rotary table, this completely self-contained,
computer operated unit is perfect for repetitive radial
operations like gear cutting or drilling multiple hole
patterns. Using the keypad, enter the parameters such as
the number of divisions required . When the command is
given, the indexer will move precisely to the next
programmed position. The computer keeps track of the
divisions to many decimal places, so error is virtually
eliminated. The unit includes a computer/keypad unit,
rotary table, motor mount, stepper motor, power supply
and all connecting cables. It can also be “daisy chained”
with other units to produce sequenced operations.
HORIZONTAL MILLING CONVERSION (P/N 6100)
FOR 5000/5400-SERIES MILLS
A number of milling operations require the application of
the cutting tool from the side rather than from the top. A
3/4" thick aluminum base 10.5" x 12.5" allows the 5000-
series mill column to be mounted separately from the base
for a variety of milling configurations. The headstock is
rotated 90° and work is machined from the side, allowing
larger surfaces to be worked on without having to reclamp

the work. (Note: The greater versatility and capacity of
the 2000-series 8-direction mill eliminate the need for this
accessory on those mills.)
The black anodized mounting plate is predrilled to mount
the base and column in several possible locations.
Alignment bars and a selection of appropriate bolts are
included to make it easy to accurately relocate the column.
Rubber feet insulate the table for quiet, vibration-free
operation. (Note: The column base should be shortened
by 2" for best operation. Instructions are provided with
the accessory, or we can shorten your column for you. The
modification is listed as P/N 6101 on the price list. New
mills purchased along with the horizontal milling
conversion can be ordered with the column already split.)
