7.0 Set-up and assembly
Open shipping container and check for shipping
damage. Report any damage immediately to your
distributor and shipping agent. Do not discard any
shipping material until Turret Mill is assembled and
running properly.
Compare contents of your container with the
following parts list to make sure all parts are intact.
Missing parts, if any, should be reported to your
distributor. (Check machine first in case parts have
been preinstalled.)
If your mill is supplied with an optional Table
Powerfeed and/or DRO (digital read-out), be sure
to consult the separate instruction materials that
accompany them.

1 Lifting ring
1 Operator’s Manual
1 Product Registration Card
* parts with asterisk are also included in tool box
service kit JTM1050VS2-TB.
7.2 Site preparation
The mill must be placed on an even surface and
bolted to the floor. Anchor bolts of sufficient size
and length must be fastened to the floor according
to the mill’s footprint. See layout diagram in Figure
5-1.
The diagram shows maximum dimensions of the
Mill with table and ram fully extended to maximum
travel. When spotting the machine, leave room not
only for the machine itself, but also clearance for
the operator, for servicing the machine, and for any
unusual size of workpiece that might extend off the
machine’s table.

Finish removing the sides of the crate. Remove
any accessory items from machine table and
shipping pallet. Leave mill bolted to pallet until
ready to move to its final location.
The preferred method for lifting is with a hook
through the lifting ring screwed into the tapped hole
atop the ram:
1. Install provided lifting ring into tapped hole
atop ram. (Note: If your mill came with a topmounted DRO, remove DRO from hole to
install lifting ring. Reinstall DRO after machine
has been positioned.)
2. Check lifting ring on ram to be certain it is
tight.
3. Check tightness of lock hex nuts on ram (A,
Figure 7-2) to be certain ram is tightly
locked.
4. Remove fasteners holding mill to pallet.
An alternative method for lifting the mill is with a
sling. See Figure 7-2 for proper position of sling
under ram. Note position of ram and that table has
been moved against column. Tighten ram locking
nuts (A, Figure 7-2) before lifting.
5. Center an overhead crane or other suitable
overhead lifting device and sling arrangement
over the lifting ring.
IMPORTANT: This machine weighs nearly
2500 pounds. Be certain lifting arrangement is
new or in excellent condition and has a safety
factor that will account for age, difficulties in
lifting, etc.
9
When lifting using the ring, the machine may
tend to tip forward. If you wish, you can
minimize this tipping by rigging a support sling
over the front of the machine. Be careful when
doing this, to prevent the sling from damaging
any components on the front of the machine.
Be sure to steady the mill to prevent it from
spinning.
6. Lift machine off pallet no higher than
necessary to clear the hold-down hardware,
then slide pallet out of the way. Do NOT get
hands or feet underneath machine when
removing pallet.
7. Put machine base over the hold-down system
where the machine will be spotted.
8. When the mill is over its anchors, level the mill
using shims under the corners needing them.
The machinist’s level used for leveling should
be placed on the table. The table is the
reference surface for both side-to-side and
fore-and-aft leveling. Be certain you get it level
in BOTH directions.
Mill must be supported
equally under all four corners. Failure to
comply may cause the column to twist and
put a bind in the table ways.
9. When the machine is level, secure base to
anchoring system.
Figure 7-2: alternate lift - sling location
7.4 Completing assembly
Before attempting to raise mill
head, familiarize yourself with instructions in
sect. 10.6, for procedures to safely raise and
set up the mill head.
1. Loosen the four hexagonal nuts (see A, Figure
10-4) about one-quarter (1/4) turn each
counter-clockwise, just enough to allow
rotation of the head.
2. Apply upward pressure on motor by hand to
relieve pressure on worm mechanism, while
using supplied wrench to turn worm shaft (B,
Figure 10-4). Raise head to upright position.
3. Tighten nuts (A, Figure 10-4); not torqued at
this time, just snug. Before operating mill,
follow procedures in sect. 10.6 to verify angle
settings and properly tighten the four nuts.
4. Using mineral spirits or other cleaning solvent,
clean all of the rust proofing from where it may
have been applied. This is important; moving
the table or any other components before
removing the rust proofing will only put rust
proofing where you don’t want it. (Do not use
gasoline, paint thinner, or lacquer thinner these will damage painted surfaces.)
5. Lubricate exposed ways, then move each unit
(table and ram) to the opposite limit stop, and
clean and lubricate the newly exposed ways.
Loosen bolts to unlock ram and move it
forward and backward to the full length in
order to clean and lubricate.
6. Cover all machined surfaces with a film of light
machine tool oil to inhibit rust.
Some of the following steps may have already
been performed on the machine. If so, skip the
instructions related to those particular steps.
Otherwise, perform them in the order listed. Refer
to Figures 6-1 and 9-1 to help locate items.
7. Install handles on the table longitudinal and
cross-feed cranks. Use a wrench on the flats
to tighten them.
8. Remove any rust proofing from drawbar (O,
Figure 9-1) and its washer, and place drawbar
with washer installed into spindle center
through top of machine.
9. Slide fine feed handwheel (J, Figure 9-1) over
handwheel hub and push it back until its roll
pin engages hole in the hub and handwheel is
flush with hub surface.
10. Place coarse feed handle (F, Figure 9-1) on
feed shaft and tap it lightly until its roll pin
engages a hole in the hub. Tighten set screw
to secure handle.
10
11. Unwrap and clean elevating (knee) crank and
install it on its shaft. Secure it with washer and
socket cap screw preinstalled on shaft.
12. Install rubber way covers at front and behind
table.
7.5 Lubrication
Do not operate Mill before fully
lubricating it. Failure to comply may cause
damage to the machine.
Before operating mill, refer to sect. 11.2 for
lubricating instructions.
8.0 Electrical Connections
Electrical connections must
be made by a qualified electrician. This
machine must be properly grounded in
accordance with the National Electrical Code
and local codes and ordinances, to help
prevent electrical shock and possible fatal
injury.
The JTM-1050VS2 Mill is rated at 230/460V, 3phase and comes from the factory prewired at
230V. Confirm power at the site matches power
requirements of the Mill before connecting to power
source. The power source should be dedicated to
the Mill.
Remove junction box cover, and run main power
cable through box and attach the ground, followed
by power leads. Replace junction box cover.
Check for proper spindle rotation in the high speed
range. The spindle should rotate clockwise when
viewed from top of machine. If spindle rotates
counterclockwise, disconnect from power source,
and switch any two of the three power leads.
8.1 Voltage conversion
To change to 460V operation, remove junction box
cover on the motor, and change the wires
according to diagram found on inside of junction
box cover. A similar wiring diagram is found at the
back of this manual. If discrepancies arise, diagram
on machine takes precedence.
8.2 Wire Sizes
For circuits which are far away
from the electrical service box, the wire size
must be increased in order to deliver ample
voltage to the motor.
To minimize power losses and to prevent motor
overheating and burnout, the use of wire sizes for
branch circuits or electrical extension cords
according to Table 2 is recommended.

9.0 Operation
9.1 Precautions
Do not attempt to change spindle RPM while
motor is stopped. Only change spindle speeds
while motor is running.
Verify that spindle brake is released before
starting motor.
Rotate spindle by hand to facilitate meshing of
clutch and gears.
Do not use quill automatic feed at spindle
speeds above 3000 RPM.
It is recommended that the auto feed worm
gear be disengaged whenever auto feed is not
required. This will avoid unnecessary wear on
the worm gear.
Maximum auto feed loading is a 3/8” (9.5mm)
diameter bit for drilling in mild steel. Use
manual feed for bits larger than 3/8".
Overload clutch is factory set to hold up to 200
lbs. down feed pressure on the quill
(accommodates drills up to 3/8"). Do not
attempt to adjust clutch pressure.
11
9.2 Operating controls
Refer to Figure 9-1.
A. Variable speed control (A, Figure 9-1) –
Turn handwheel to adjust spindle speed.
Change spindle speed
only when motor is running. Failure to
comply may result in damage to drive
mechanism.
B. Variable speed dial indicator (B) –
Indicates selected speed in high or low
range.
C. Spindle brake (C) – Move in either direction
to stop spindle after power has been turned
off.
D. Speed range lever (D) – Push handle
inward and move to desired position. Upper
position is high speed. Middle position is
neutral. Low position is low speed (back
gear engagement). A label is affixed near
the lever for reference.
Lever (D) while motor is running. Turn off
machine and rotate spindle by hand to
facilitate changing lever positions.
Do not move Speed Range
E. Auto feed engagement lever (E) – To
engage auto feed, stop spindle, then pull
knob outward and move lever to opposite
hole. Engage pin in hole. A label is affixed
near the lever for reference.
Auto feed may be
engaged when spindle is rotating,
however, it must be engaged gently to
avoid damage to worm gear.
Do not use auto feed at spindle
speeds above 3000 R.P.M.
It is recommended that auto feed
lever be disengaged when not in use.
This avoids unnecessary wear on
worm gear.
Maximum auto feed loading is a 3/8"
(9.5mm) diameter bit for drilling in
steel. Use manual feed for bits larger
than 3/8".
F. Coarse feed handle (F) – Used for non-
precision drilling operations and for moving
quill to a specific depth. Rotate counterclockwise to lower spindle. A return spring
will retract spindle automatically once
handle is released.
Figure 9-1: Controls
G. Quill lock (G) – Rotate handle clockwise to
lock quill in desired position; counterclockwise to release.
H. Micrometer adjusting nut (H) – Used for
setting spindle depth, according to adjoining
scale. Press button to rapidly slide nut for
general positioning. Release button and
rotate nut for fine adjustment. Note: One
complete rotation of micrometer adjusting
nut equals 0.025” (0.635mm) of spindle
travel.
I. Feed trip control lever (I) – Engages
overload clutch on pinion shaft when lever is
positioned to the left. Stays engaged until
quill stop comes into contact with
micrometer adjusting nut (forcing feed
control lever to drop out automatically), or
until lever is released manually by moving
lever to the right.
J. Manual fine feed handwheel (J) – Feed
direction control knob (K) must be in neutral
position. The feed control lever (I) must be
engaged. Note: Manual feed handwheel
may be removed when not in use.
K. Feed direction control (K) – located in
center of manual feed handwheel. Position
of knob depends upon direction of spindle
rotation. If boring with right hand cutting
tools, pull feed knob towards operator until
clutch becomes engaged. Neutral position is
between forward and reverse position.

10.6 Mill head – left/right rotation
Make sure machine base is
secured to floor before repositioning mill head.
Center of gravity can shift enough to cause
machine to tip over, resulting in serious injury
to operator and damage to machine.
1. Loosen four large hexagonal nuts (A, Figure
10-4) that secure mill head to ram adapter.
One-quarter (1/4) turn should be sufficient to
allow the head to move.
NOTE: For angles greater than 10 degrees,
use your free hand to support mill head, taking
some weight off the brass worm gears. Doing
so will greatly lengthen life of the worm gears.
2. Turn worm shaft (B, Figure 10-4) to rotate
head left or right as required. Use scale on
ram adapter to set desired angle.
Note: The scales on ram adapter and for head
rotation are guides only. Close tolerance work
will require use of a dial indicator to make sure
head is 90° to table in X and Y axis. Please
note that table is fitted to be slightly higher in
front, usually about 0.0005”.
Note: Due to variables in tool diameter, coatings,
coolant, and materials, no specific spindle speed or
feed rate recommendations are provided. Use
machinery handbooks that have data applicable to
the milling and drilling operations being performed.
Or, contact the suppliers of the tooling, coolant and
material for specific recommendations.
10.5.1 Depth stop for auto feed
Refer to Figures 9-1 and 10-3.
1. Lower quill to required depth.
2. Tighten quill lock (G, Figure 8).
3. Move micrometer nut (H) against quill stop (L).
4. Loosen quill lock (G), and engage auto feed
lever (E).
Figure 10-4: Mill head movement - rotation
Be sure to apply torque in two
steps using a crossing pattern. Failure to do so
could distort face of ram adapter.
3. Tighten the four hexagonal nuts (A). Tighten in
two steps using a calibrated torque wrench.
Use a crossing pattern to tighten the nuts.
Tighten initially to 25 foot-pounds.
15
4. Before applying final torque, check to make
sure mill head is perpendicular to worktable.
5. Set up a dial indicator in a collet and secure
using draw bar (see Figure 10-5).
Figure 10-5: Test perpendicularity
6. Put spindle drive in neutral (D, Figure 9-1).
7. Set dial indicator plunger on worktable. Zero
the indicator.
8. Rotate spindle 180 degrees (when rotating,
raise dial indicator plunger by hand to prevent
it from dropping into table T-slots).
9. Read dial indicator – it should read zero. If not,
loosen the four hex nuts (A) and reposition mill
head.
10. Recheck perpendicularity using dial indicator.
Repeat procedure above until dial indicator
reads zero in both positions.
Be sure to apply torque in two
steps using a crossing pattern. Failure to do so
could distort face of ram adapter.
11. Tighten the four hex nuts (A). Tighten in two
steps using a calibrated torque wrench. Use a
crossing pattern to tighten the nuts. Tighten
initially to 25 foot-pounds, then tighten to a
final torque of 50 foot-pounds.
10.7 Mill head – front/back tilt
Setting the angle:
1. Loosen three ram adapter locking bolts (E
Figure 10-6). There is no need to loosen the
bolts more than one-half (1/2) turn to allow
tilting.
,

Figure 10-6: Mill head movement – tilting
2. Support mill head with your free hand. Press
upward on spindle when tilting.
3. Turn ram adapter worm nut (E
, Figure 11) to
2
tilt head forward and backward. Use scale on
ram adapter (E
) to locate desired angle.

Returning to upright position:
1. When returning mill head to full upright
position, support head by upward pressure on
spindle as you turn worm nut.
2. Check to make sure mill head is perpendicular
to worktable.
3. Set up a dial indicator in a collet and secure
using draw bar (see Figure 10-5).
4. Put spindle drive in neutral.
5. Set dial indicator plunger on worktable. Zero
the indicator.
6. Rotate spindle 180 degrees. (When rotating,
raise dial indicator plunger by hand to prevent
it from dropping into the table T-slots).
7. Read dial indicator. The indicator should read
zero. If not, loosen locking bolts (E
, Figure 11)

ram forward or back.
3. When desired position is reached, tighten hex
nuts (G) securely.
16
Figure 10-7: Ram positioning
10.8.2 Rotating ram on turret
Refer to Figure 10-7.
Make sure machine base is
secured to floor before repositioning ram.
Center of gravity can shift enough to cause
machine to tip over, resulting in serious injury
to operator and damage to machine.
1. Loosen four turret lock bolts (J, Figure 12).
One-half (1/2) turn should be sufficient to allow
turret movement.
2. Swing ram until spindle is in desired position.
Note: Use gentle hand pressure to avoid rapid
movement. Use scale (I) on turret for degree
measurement.
3. Securely sighten four turret lock bolts (J).

11.0 User-maintenance
Always disconnect machine
from power source before doing maintenance.
If you do not have knowledge or training to
complete the maintenance, have an authorized
JET service center maintain your mill. Failure to
comply may cause serious bodily injury.
11.1 General maintenance
During operation, occasionally vacuum and
brush chips and debris from machine.
Periodically operate knee and table lead
screws through full range of movement to
evenly distribute lubricant (particularly when
applied using the “one-shot” system).
Periodically apply light machine oil to work
table and other exposed metal surfaces to
prevent rust or corrosion.
Periodically remove side panels to check
pulleys and belts for unusual wear or grooving.
Operators should vary speed occasionally to
prevent groove formation on pulley surfaces.
When using a coolant pump, periodically clean
the sump in the machine base to extend pump
life and promote efficient cutting. Change
coolant regularly at intervals recommended by
coolant supplier.
11.2 Lubrication
Do not operate mill before
fully lubricating it. Failure to comply may cause
damage to machine.

11.3 Gib adjustments
Refer to Figure 11-3.
The table, saddle, knee and ram are equipped with
adjustable gibs. The gibs may require adjustment if
unusual vibration is noted when locking
mechanisms are off, or if you experience unusual
vibration when spindle speed, tooth pitch or depth
of cut do not account for the vibration.
NOTE: When adjusting table, saddle and knee
gibs, always start with knee first; adjust saddle
second, and adjust table last.
11.3.1 Knee gibs
Adjust gibs located between knee and column by
turning two adjustment screws beneath the wipers
(A, Figure 11-3). Use a dial indicator to measure
amount of movement in knee. Adjust gib until
indicator reading is within 0.003”.
11.3.2 Saddle gib
Adjust gib located between saddle and knee by
turning two adjustment screws (B, Figure 11-3) at
front and back of saddle. Use dial indicator to
measure amount of movement in saddle. Adjust
gib until indicator reading is within 0.003”.
18
11.3.3 Table gib
Adjust gib between table and saddle by turning two
adjustment screws (C, Figure 11-3) at left and right
of saddle. Use dial indicator to measure amount of
movement in table. Adjust gib until indicator
reading is within 0.003”.
Figure 11-3: Gib locations
11.3.4 Ram gib
Adjust ram gib (E, Figure 11-4) by turning the two
set screws (F).
Figure 11-4: Ram gib location
11.4 Leadscrew backlash adjustment
The milling machine table is moved by a leadscrew
and nut for each machine axis. For proper
operation, there must be clearance between
leadscrew and nut, which may result in backlash. A
second feed screw nut is provided to eliminate
most of the backlash. The following procedures
provide instructions for obtaining acceptable
backlash.
11.4.1 Cross feed backlash
Refer to Figure 11-9.
1. Use cross feed crank to move table to extreme
rear of its travel (toward column).
2. Remove pleated way cover.
3. Open chip guards (#51-53, sect. 13.3.1)
enough to expose cross feed adjustment nut
(the nut toward rear of feed nut bracket is not
adjustable; only front nut is adjustable).
4. Loosen the two nut locking screws.
5. Turn nut slightly to tighten it against opposing
nut.
6. Tighten the two nut locking screws.
7. Using cross-feed crank, move table to middle
position.
8. Set up a dial indicator to check cross feed
backlash. Gently move cross feed crank back
and forth while watching dial indicator.
Backlash should be between 0.003 inch and
0.005 inch.
9. If necessary, repeat the above steps to set
backlash.
10. Install pleated way cover.
11.4.2 Longitudinal backlash
Refer to Figure 11-9.
1. Only one of the longitudinal leadscrew nuts
can be adjusted; the other nut is fixed. The left
hand nut is typically adjustable. This can be
determined by looking at nut from underside of
table.
2. Loosen the two nut locking screws.
3. Turn the nut slightly to tighten it against the
opposing nut.
4. Tighten the two nut locking screws.
5. Using one of the longitudinal table cranks,
move table to middle position.
6. Set up a dial indicator to check longitudinal
backlash. Gently move crank back and forth
while watching dial indicator. The backlash
should be between 0.003 inch and 0.005 inch.
7. If necessary, repeat the above steps to set
backlash.
