1. Forward:
SHARP LMV milling machines are designed and manufactured to meet
the demands of our customers. All parts and materials have been placed
under strict quality control to ensure the superior quality and durability.
This manual gives a detailed account of the structure, mechanism, and
methods of operation and maintenance of the LMV mill. To ensure the
maximum performance and precision operation, it is imperative that
operators, maintenance and repair personnel read the manual thoroughly
and follow the specific instructions in operating and maintaining the
machine.
2. Safety Rules and Regulations:
1. Do not wear loose clothing when operating the machine.
2. Operators shall wear goggles and safety boots.
3. Do not disturb the operator when the machine is running.
4. Caution should be taken when removing chips from work surface.
3. Notice:
Retrofitting the Sharp Mill with a CNC control, such as Sony, AcuTire,
Anilam or other similar controls without the installation of an approved
auto-lube system will void the warranty on that machine.

6. Operation:
1. Headstock:
a. Power to the motor is controlled by a three way switch, forward,
reverse, and off (Fig. 9). When the high-low speed change lever (Fig.
3 (J), Page 3) is in high gear position and the switch is in FOR., the
spindle rotation is clockwise. When the switch is in REV., the rotation
is counter clockwise.
b. Spindle Brake:
To prevent damage and prolong the life of the brake, the power must
be off and the spindle must be below 200 RPM before engaging brake.
The brake can be engaged by pushing or pulling the brake lever (Fig.
10). Pulling the brake lever up after it is engaged can lock the brake.
Caution: Be sure the brake is in neutral before starting the spindle.
c. Installation of Collet:
1. Raise the spindle all the way up.
2. Insert collet, being sure the keyway lines up with the pin
in the spindle.
3. To tighten, turn the drawbar clockwise while brake is
engaged. To remove collet, loosen the drawbar (counter
clockwise) three to five turns and tap the drawbar with a soft
mallet to break the collet loose from the taper.
NOTE: When the mill is fitted with the R8 spindle, care must be taken that the collet keyway
is aligned with the pin in the spindle (Fig. 36, page 35).

d. Manual Feed:
The manual feed lever is located on the right side of the headstock
(Fig. 3 (H), Page 3). This lever controls the vertical movement of the
spindle. For the operator’s convenience the lever can be adjusted as
needed.
Note: in manual feed, the feed control handle “F” (Fig. 11) must be in
the “F1” position.
e. Manual Micro-feed:
To use the manual micro-feed, the power-feed transmission lever (J)
(Fig. 11) must be placed at the “OUT” position, and the feed reverse
knob (D) (Fig. 11) must be in the neutral position. To engage the
overload clutch, lever “F” (Fig. 11) must be moved to the “F2” (Fig.
11). You can now turn handwheel “E” clockwise to lower the spindle,
counter clockwise to raise it.

12
f. Automatic feed:
Procedure for using this function is:
a. Loosen the quill lock “L” (Fig. 3, Page 3)
b. Place the power feed transmission lever “I” (Fig. 3,
page 3) in the “IN” position.
c. Place feed speed lever “C” (Fig. 3, Page 3) in the
desired position. (H, L, or M).
d. To engage the overload clutch, place feed control lever
“F” to the “F2” position (Fig. 12).
e. The quill will move down when pressing knob “D” (Fig.
11) in, and pulling it out, the quill will go up (The
middle is neutral).
f. The working depth can be set by the use of micrometer
adjustment nut “K” (Fig. 12). This adjusting nut is
graduated in 0.001 and 0.02 mm increments. To activate
the auto feed, pull the feed control lever “F” out. It will
disengage when the adjusting nut contacts the quill stop
block “I” (Fig. 12). For manual trip, you can push the
feed control lever in manually.
Note:
1. Maximum drilling capacity for automatic feed is 3/8” or 10
mm.
2. The power feed transmission lever “I” (Fig. 3, Page 3) should
be in the “OUT” position when the power feed is not being
used. To avoid damage to the gears, do not engage the power
feed when the spindle is running.

g. Spindle speed change:
The speed of spindle is controlled by a set of sliding belt
pulleys and a counter shaft gear. There are two
options (High and low). High gear is for RPM from 500
to 3,000 and low gear for RPM from 60 and 580. When
high-low lever “J” (Fig. 13) is in the forward position it
is in high gear, when facing back it is in low gear.
Note: To change from high to low:
a. The spindle must be stopped.
b. Moving the spindle slightly by hand when
shifting from high to low makes it easier for the
gears to engage. You will feel a click when it
engages.
c. The direction of the spindle is reversed when in
low gear. This can be overcome by the use of
“FOR” “REV” switch.
h. Speed change handwheel:
a. Do not change speed when spindle is stopped.
b. Do not run spindle in excess of 3,000 RPM.
c. Slow speed changes are advised, to prevent premature wear
on the belt, pulley, and other internal parts.

i. Tilting the headstock (Fig. 14):
To tilt the head up or down, evenly loosen the three
adapter locking bolts (P) and move to desired angle
using adjusting worm shaft “Q”. Re-tighten the adapter
bolts. NOTE: do not remove adapter bolts.
Cross tilting the headstock (Fig. 15):
Evenly loosen the four lock nuts “R”. Using the worm
shaft “S” move head to desired angle and retighten lock
nuts.

2. Machine Body Operation:
1. Ram movement (Fig. 17):
a. To move ram in or out, loosen Ram lock levers “A” and
move to desired position using handle “B” and retighten
levers.
b. To swivel ram, loosen the four bolts “C”, move to
desired position and retighten bolts “C”.

2. Setting handwheel dials to zero (Fig. 18):
a. Loosen lock ring “D”.
b. Turn dial “E” to zero and tighten lock ring “D”.
3. Locking the table, saddle, and knee:
To increase the stability of the mill and maintain a good
workpiece finish, all non-feeding surfaces should be
locked down. See Fig. 19 for location of locking levers.

7. Unpacking, moving, and floor space:
a. Methods of moving machine:
1. Prior to unpacking or removing from skid, the machine should be
moved by the use of a forklift or reinforced cable (Fig. 20 & 21).
2. Removal from the skid and any further movement of the machine
should be done by the use of a reinforced cable or by the eye bolt
located in the top of the ram.
Remarks:
1. When lifting or moving machine, be sure area is clear of all personnel.
2. Lifting machine by the use of eye bolt should be only when absolutely
necessary.
3. When lifting or moving the machine before unpacking or removing
from the skid, observe any precautions or instruction that may be
printed on the crate.
4. The machine can be balanced while being moved by changing the
location of table and or saddle.
5. Do not attempt to raise the machine too high. The recommended height
is approximately 10 cm from the ground.
6. If the machine is not stable when being lifted, adjust the rigging as
needed.
7. Only use qualified forklift operators to move the machine.

b. Unpacking:
1. To protect the machine while in transit it is necessary to cover it with a
rust proof coating and a crate or plastic wrapping. In the event, there is
damage due to moisture, please contact our agent or the transporter.
2. After unpacking, make sure all tools and accessories are intact. If not,
contact our agent.
3. Restore headstock to its normal position (Fig. 3, Page 3)
4. Do not move the sliding surfaces until all of the protective rustproof
coating is removed and all surfaces are well oiled.
5. Do not remove the oil wipers when cleaning the machine.
6. Do not use gasoline or other flammable cleaners.
