The Model G0678 vertical mill is used to remove

material from metal workpieces to form complex

shapes. Tooling is inserted into the spindle, which

can positioned in nearly any orientation above the

table and workpiece.

During most operations, the workpiece is clamped

to the table, then it is moved into the rotating cut-

ter in any combination of three paths—longitudi-

nal (X-axis), cross (Y-axis), and vertical (Z-axis).

The range of movement for the table is greater

than that of the head and spindle. However some

operations, such as drilling or tapping, are better

accomplished with vertical quill (spindle) move-

ment, using the coarse or fine downfeed con-

trols.

This mill uses a frequency drive to convert incom-

ing 220V single-phase power to 220V 3-phase

for efficient performance from the spindle motor.

Power is transferred directly to the spindle from

the motor by a V-belt and pulleys.

Spindle speed is electronically controlled by using

the variable speed dial and readout on the control

panel.

14. CUTTING TOOL INSPECTION. Inspect

drills and end mills for sharpness, chips,

or cracks before each use. Replace dull,

chipped, or cracked cutting tools immedi-

ately. Handle new cutting tools with care.

Leading edges are very sharp and can

cause lacerations.

15. SPINDLE DIRECTION CHANGES. Never

reverse spindle direction while the spindle is

in motion.

16. EXPERIENCING DIFFICULTIES. If at any

time you are experiencing difficulties per-

forming the intended operation, stop using

the machine! Contact our Technical Support

at (570) 546-9663.

The unpainted surfaces are coated with a waxy

oil to prevent corrosion during shipment. Remove

this protective coating with a solvent cleaner or

degreaser, such as shown in Figure 4. For thor-

ough cleaning, some parts must be removed.

For optimum performance, clean all moving

parts or sliding contact surfaces. Avoid chlo-

rine-based solvents, such as acetone or brake

parts cleaner that may damage painted surfac-

es. Always follow the manufacturer’s instructions

when using any type of cleaning product.

Clean Up

Gasoline and petroleum

products have low flash

points and can explode

or cause fire if used to

clean machinery. DO

NOT use these products

to clean the machinery.

Many cleaning solvents

are toxic if inhaled.

Minimize your risk by only

using these products in a

well ventilated area.

Floor Load

Refer to the Machine Data Sheet on Page 4 for

the weight and footprint specifications of your

machine. Some residential floors may require

additional reinforcement to support both the

machine and operator.

Placement Location

Consider existing and anticipated needs, size of

material to be processed through each machine,

and space for auxiliary stands, work tables or

other machinery when establishing a location for

your new machine. See Figure 5 for the minimum

working clearances.

Children and visitors may be

seriously injured if unsuper-

vised around this machine.

Lock entrances to the shop

or disable start switch or

power connection to prevent

unsupervised use.

Moving & Placing

Base Unit

The Model G0678 is a

heavy machine. Serious

personal injury may

occur if safe moving

methods are not used.

To be safe, get assis-

tance and use power

equipment rated for at

least 1500 lbs. to move

the shipping crate and

remove the machine

from the crate.

To move and place your mill:

1. After removing the crate from the shipping

pallet, wrap lifting straps around the turret, as

shown in Figure 6, and securely attach them

to your power lifting equipment.

Although not required, we recommend that you

mount your new machine to the floor. Because

this is an optional step and floor materials may

vary, floor mounting hardware is not included.

Generally, you can either bolt your machine to

the floor or mount it on machine mounts. Both

options are described below. Whichever option

you choose, it is necessary to level your machine

with a precision level.

Mounting to Shop

Floor

NOTICE

Anchor studs are stronger and more per-

manent alternatives to lag shield anchors;

however, they will stick out of the floor,

which may cause a tripping hazard if you

decide to move your machine.

Figure 8. Machine mount example.

Using Machine Mounts

Using machine mounts, shown in Figure 8, gives

the advantage of fast leveling and vibration reduc-

tion. The large size of the foot pads distributes

the weight of the machine to reduce strain on the

floor.

NOTICE

We strongly recommend securing your

machine to the floor if it is hardwired to the

power source. Consult with your electrician

to ensure compliance with local codes.

2. Use a

⁄2" wrench to unbolt the mill from the

pallet.

3. With assistance to steady the machine, lift

it just enough to clear the pallet and floor

obstacles, then move it to the prepared loca-

tion.

4. When mounting the machine to the floor, use

a precision level to make sure the table is

level from side-to-side and front-to-back.

Note: If necessary, use shims to make sure

there are no gaps between the base and the

floor to avoid cracking or warping the cast

iron.

Bolting to Concrete Floors

Anchor studs and lag shield anchors with lag

bolts (see Figure 7) are two popular methods for

anchoring an object to a concrete floor. We sug-

gest you research the many options and methods

for mounting your machine and choose the best

that fits your specific application.

concrete floors.

Assembly

To assemble your mill:

1. Secure the three handles to the handwheels

with the M6-1 x 25 cap screws, as shown in

Figure 9.

2. Use the external retaining ring pliers to

remove the retaining ring from the end of

the vertical crank screw, reverse the crank

handle, then re-install the retaining ring (see

Figure 10).

Before starting the mill, make sure you

have performed the preceding assembly

instructions, and you have read through the

rest of the manual and are familiar with the

various functions and safety features on

this machine. Failure to follow this warning

could result in serious personal injury or

even death!

Test Run

Once the assembly is complete, test run your

machine to make sure it runs properly and is

ready for regular operation. The test run consists

of verifying the following: 1) The motor powers up

and runs correctly and 2) the stop button safety

feature works correctly.

If, during the test run, you cannot easily locate

the source of an unusual noise or vibration, stop

using the machine immediately, then review

Troubleshooting on Page 28.

If you cannot find a remedy, contact our Tech

Support at (570) 546-9663 for assistance.

To test run the machine:

1. Make sure you understand the safety instruc-

tions at the beginning of the manual and that

the machine is set up properly.

2. Make sure all tools and objects used during

setup are cleared away from the machine.

3. Make sure the machine is lubricated (refer to

Lubrication on Page 25 for detailed instruc-

tions).

4. Refer to Basic Controls on Page 16 to

become familiar with the control panel func-

tions.

5 . Connect the machine to the power source—

the power lamp on the control panel should

light.

dial to decrease/increase the spindle speed.

9. Press the stop button to stop the machine.

10. WITHOUT resetting the switch, press the ON

button. The machine should not start.

—If the machine does not start, the stop but-

ton safety feature is working correctly. The

Test Run is complete.

—If the machine does start (with the stop

button pushed in), immediately disconnect

power to the machine. The stop button

safety feature is not working correctly. This

safety feature must work properly before

proceeding with regular operations. Call

Tech Support for help.

When all of the Test Run procedures are success-

fully completed, proceed to Spindle Break-In.

Figure 11. Resetting the switch.

6. Push the stop button in, then twist it clock-

wise so it pops out. When the stop button

pops out, the switch is reset and ready for

operation (see Figure 11).

Spindle Break-In

NOTICE

Successfully complete the spindle break-in

procedure to avoid rapid wear of spindle

components when placed into operation.

It is essential to closely follow the proper break-in

procedures to ensure trouble-free performance of

your mill.

To perform the spindle break-in procedure:

1. Turn the machine ON, then use the speed

dial to adjust the spindle speed to approxi-

mately 200 RPM.

2. Let the mill run at this speed for 20 minutes,

then turn the spindle OFF and wait for it to

stop.

3. Use the spindle direction switch on the con-

trol panel to reverse the spindle direction,

then turn the mill ON and let it run for another

20 minutes.

4. Set the spindle speed at approximately 1800

RPM, then repeat Steps 2–3.

5. Turn the mill OFF. The spindle break-in is

now complete and the machine is ready for

operation.
