Machine Description

Manufacture Date

of Your Machine

the mill/drill is used to shape metal and solid

workpieces by removing material with the use of

a rotating cutting tool.

in milling operations, the cutting tool remains sta-

tionary while the workpiece is drawn across it by

moving the table.

For your convenience, we post all available man-

uals and manual updates for free on our website

at www.grizzly.com. Any updates to your model

of machine will be reflected in these documents

as soon as they are complete.

in drilling operations, the workpiece is held sta-

tionary on the table while the cutting tool moves

up-and-down with the movement of the spindle

and head.

SEcTION 2: pOWER SuppLy

Availability

circuit Requirements

This machine is prewired to operate on a 110V

power supply circuit that has a verified ground and

meets the following requirements:

Before installing the machine, consider the avail-

ability and proximity of the required power supply

circuit. If an existing circuit does not meet the

requirements for this machine, a new circuit must

be installed. To minimize the risk of electrocu-

tion, fire, or equipment damage, installation work

and electrical wiring must be done by a qualified

electrician in accordance with all applicable codes

and standards.

Nominal voltage ...............................110v/120v

cycle..........................................................60 Hz

phase........................................... Single-phase

power Supply circuit ......................... 15 Amps

A power supply circuit includes all electrical

equipment between the breaker box or fuse panel

in the building and the machine. The power sup-

ply circuit used for this machine must be sized to

safely handle the full-load current drawn from the

machine for an extended period of time. (If this

machine is connected to a circuit protected by

fuses, use a time delay fuse marked D.)

Electrocution, fire, or

equipment damage may

occur if machine is not

correctly grounded and

connected to the power

supply.

For your own safety and protection of

property, consult a qualified electrician if

you are unsure about wiring practices or

electrical codes in your area.

full-Load current Rating

The full-load current rating is the amperage a

machine draws at 100% of the rated output power.

On machines with multiple motors, this is the

amperage drawn by the largest motor or sum of all

motors and electrical devices that might operate

at one time during normal operations.

Note: The circuit requirements listed in this man-

ual apply to a dedicated circuit—where only one

machine will be running at a time. If this machine

will be connected to a shared circuit where mul-

tiple machines will be running at the same time,

consult a qualified electrician to ensure that the

circuit is properly sized for safe operation.

full-Load current Rating at 110v.....3.2 Amps

The full-load current is not the maximum amount

of amps that the machine will draw. If the machine

is overloaded, it will draw additional amps beyond

the full-load rating.

If the machine is overloaded for a sufficient length

of time, damage, overheating, or fire may result—

especially if connected to an undersized circuit.

To reduce the risk of these hazards, avoid over-

loading the machine during operation and make

sure it is connected to a power supply circuit that

meets the requirements in the following section.

-11-

model g0704 (mfg. since 09/09)

Download from Www.Somanuals.com. All Manuals Search And Download.

Improper connection of the equipment-grounding

wire can result in a risk of electric shock. The

wire with green insulation (with or without yellow

stripes) is the equipment-grounding wire. If repair

or replacement of the power cord or plug is nec-

essary, do not connect the equipment-grounding

wire to a live (current carrying) terminal.

Grounding & plug Requirements

This machine MUST be grounded. In the event

of certain malfunctions or breakdowns, grounding

reduces the risk of electric shock by providing a

path of least resistance for electric current.

This machine is equipped with a power cord that

has an equipment-grounding wire and a ground-

ing plug (similar to the figure below). The plug

must only be inserted into a matching receptacle

(outlet) that is properly installed and grounded in

accordance with all local codes and ordinances.

Check with a qualified electrician or service per-

sonnel if you do not understand these grounding

requirements, or if you are in doubt about whether

the tool is properly grounded. If you ever notice

that a cord or plug is damaged or worn, discon-

nect it from power, and immediately replace it with

a new one.

Serious injury could occur if you connect

the machine to power before completing the

setup process. DO NOT connect to power

until instructed later in this manual.

Extension cords

We do not recommend using an extension cord

with this machine. If you must use an extension

cord, only use it if absolutely necessary and only

on a temporary basis.

GROUNDED

Extension cords cause voltage drop, which may

damage electrical components and shorten motor

life. Voltage drop increases as the extension cord

size gets longer and the gauge size gets smaller

(higher gauge numbers indicate smaller sizes).

5-15 RECEPTACLE

Grounding Prong

Any extension cord used with this machine must

contain a ground wire, match the required plug

and receptacle, and meet the following require-

ments:

5-15 PLUG

Neutral Hot

figure 3. typical 5-15 plug and receptacle.

Minimum Gauge Size...........................16 AWG

Maximum Length (Shorter is better).......50 ft.

SHOCK HAZARD!

Two-prong outlets do not meet the grounding

requirements for this machine. Do not modify

or use an adapter on the plug provided—if

it will not fit the outlet, have a qualified

electrician install the proper outlet with a

verified ground.

cleanup

Gasoline or products

with low flash points can

explode or cause fire if

used to clean machin-

ery. Avoid cleaning with

these products.

The unpainted surfaces of your machine are

coated with a heavy-duty rust preventative that

prevents corrosion during shipment and storage.

This rust preventative works extremely well, but it

will take a little time to clean.

Be patient and do a thorough job cleaning your

machine. The time you spend doing this now will

give you a better appreciation for the proper care

of your machine's unpainted surfaces.

Many cleaning solvents

are toxic if concentrat-

ed amounts are inhaled.

Only work in a well-venti-

lated area.

There are many ways to remove this rust preven-

tative, but the following steps work well in a wide

variety of situations. Always follow the manufac-

turer’s instructions with any cleaning product you

use and make sure you work in a well-ventilated

area to minimize exposure to toxic fumes.

NOTICE

Avoid chlorine-based solvents, such as

acetone or brake parts cleaner, that may

damage painted surfaces. Test all cleaners

in an inconspicuous area before using to

make sure they will not damage paint.

Before cleaning, gather the following:

•

Disposable Rags

Cleaner/degreaser (WD•40 works well)

Safety glasses & disposable gloves

Plastic paint scraper (optional)

Basic steps for removing rust preventative:

1. Put on safety glasses.

2. Coat the rust preventative with a liberal

amount of cleaner/degreaser, then let it soak

for 5–10 minutes.

3. Wipe off the surfaces. If your cleaner/degreas-

er is effective, the rust preventative will wipe

off easily. If you have a plastic paint scraper,

scrape off as much as you can first, then wipe

off the rest with the rag.

4. Repeat Steps 2–3 as necessary until clean,

then coat all unpainted surfaces with a quality

metal protectant to prevent rust.

Site considerations

Weight Load

Physical Environment

Refer to the Machine Data Sheet for the weight

of your machine. Make sure that the surface upon

which the machine is placed will bear the weight

of the machine, additional equipment that may be

installed on the machine, and the heaviest work-

piece that will be used. Additionally, consider the

weight of the operator and any dynamic loading

that may occur when operating the machine.

The physical environment where your machine

is operated is important for safe operation and

the longevity of its components. For best results,

operate this machine in a dry environment that is

free from excessive moisture, hazardous chemi-

cals, airborne abrasives, or extreme conditions.

Extreme conditions for this type of machinery are

generally those where the ambient temperature

range exceeds 41°–104°F; the relative humidity

range exceeds 20–95% (non-condensing); or the

environment is subject to vibration, shocks, or

bumps.

Space Allocation

Consider the largest size of workpiece that will

be processed through this machine and provide

enough space around the machine for adequate

operator material handling or the installation of

auxiliary equipment. With permanent installations,

leave enough space around the machine to open

or remove doors/covers as required by the main-

tenance and service described in this manual.

See below for required space allocation.

Electrical Installation

Place this machine near an existing power source.

Make sure all power cords are protected from

traffic, material handling, moisture, chemicals,

or other hazards. Make sure to leave access to

a means of disconnecting the power source or

engaging a lockout/tagout device.

Lighting

Children or untrained people

may be seriously injured by

this machine. Only install in an

access restricted location.

Lighting around the machine must be adequate

enough that operations can be performed safely.

Shadows, glare, or strobe effects that may distract

or impede the operator must be eliminated.

6. lift the machine and carefully place it onto

the stand.

The Model G0704 is a

heavy machine. Serious

personal injury may occur

if safe moving methods

are not used. To be safe,

get assistance and use

power equipment to move

the shipping crate and

remove the machine from

the crate.

7. bolt the machine to the stand with the four

m10-1.25 x 50 hex bolts and flat washers.

—if you are placing the machine on a work-

bench, it must be securely mounted to the

workbench surface.

the strongest mounting option is a "through

mount" where holes are drilled all the way

through the workbench, and hex bolts, wash-

ers, and hex nuts are used to secure the

machine to the workbench.

To remove your machine from the shipping

crate and place it in position:

1. place the crate adjacent to the location where

your machine will be placed, then remove the

shipping crate from the pallet.

using Machine Mounts

Mounting to Shop

using machine mounts, shown in figure 10, 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.

floor

although not required, we recommend that you

mount your new machine cabinet to the floor.

because this is an optional step and floor mate-

rials may vary, floor mounting hardware is not

included. generally, you can either bolt the cabi-

net to the floor or mount it on machine mounts.

both options are described below. Whichever

option you choose, it is necessary to level the

cabinet with a precision level.

bolting to concrete floors

lag shield anchors with lag bolts and anchor

studs (figure 9) 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.

figure 10. machine mount example.

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.

figure 9. typical fasteners for mounting to

concrete floors.

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.

Assembly

Drill chuck Arbor

assembly of the model g0704 consists of attach-

ing the four handwheel handles to the machine.

your machine includes an b-16 drill chuck arbor

and drill chuck. before use, the drill chuck must

be installed onto the arbor. the this drill chuck

installation is intended to be semi-permanent.

To assemble your machine:

1. With a #3 standard screwdriver, install the

large handwheel handle on the elevation

handwheel (figure 11).

Tip: For a permanent installation, chill the arbor

in the freezer for 15 minutes before performing the

following procedure. The taper will expand as it

returns to room temperature, permanently locking

the chuck.

SEcTION 4: OpERATIONS

To complete a typical operation, the operator

does the following:

Operation Overview

1. loosens the vertical travel locks, then adjusts

the headstock height above the table to

ensure there is sufficient room to install the

tooling in the spindle and the workpiece on

the table.

The purpose of this overview is to provide the nov-

ice machine operator with a basic understanding

of how the machine is used during operation, so

the machine controls/components discussed later

in this manual are easier to understand.

2. installs the desired tooling for the job.

Due to the generic nature of this overview, it is

not intended to be an instructional guide. To learn

more about specific operations, read this entire

manual and seek additional training from expe-

rienced machine operators, and do additional

research outside of this manual by reading "how-

to" books, trade magazines, or websites.

3. positions the workpiece as needed for the

operation, then clamps the workpiece using

applicable clamping devices, or a vise that is

already mounted on the table to ensure the

workpiece does not move during the milling/

drilling operation.

4. positions the cutter or drill bit near the

workpiece, then tightens vertical travel locks.

To reduce the risk of

serious injury when using

this machine, read and

understand this entire

manual before operating.

5. selects the appropriate spindle speed for the

milling or drilling operation using the speed

selector knob and variable spindle speed

knob.

6. unlocks the X- and y-axis table locks.

7. Wears safety glasses or a face shield.

Damage to your eyes and lungs could result

from using this machine without proper pro-

tective gear. Always wear safety glasses and

a respirator when operating this machine.

8. turns the spindle direction selection knob to

the desired direction.

9. loosens the quill lock lever and uses the quill

feed lever or the fine feed knob to set the cut-

ting tool height according to the workpiece.

10. For milling operations, uses the table

handwheels to move the table so the cutter

removes material evenly from the workpiece.

NOTICE

The Model G0704 drawbar will extract the

arbor from the spindle. Once the arbor or

collet has broken free from the spindle

taper, be sure to properly support it while

continuing to loosen the drawbar. failure

to properly support the arbor or collet

while loosening the drawbar will result in

the arbor or collet falling out of the spindle,

causing damage to machine components.

your cutting tool shank size.

4. use a 17mm wrench to prevent the spindle

from turning while you use an 8mm wrench to

loosen the drawbar 2–3 turns. do not con-

tinue loosening the drawbar without support-

ing the collet or it will fall from the spindle.

To install the tooling:

1. disConneCt mill/drill From poWer!

2. remove the drawbar cap.

3. Carefully clean the surface of the tooling and

spindle taper. ensure that it is free of debris

and is lightly oiled.

LAcERATION

HAzARD!

Leading edges of end mills

and other cutting tools can

be very sharp. protect your

hands with gloves or a shop

towel when handling.

4. if you are using a cutting tool and collet, insert

the cutting tool into the collet, then insert the

collet up into the spindle taper, making sure

the slot in the collet lines up with the pin in the

spindle.

NOTICE

if you are using a cutting tool that installs

directly into the spindle, insert the tool into the

spindle taper, making sure the slot in the tool

lines up with the pin in the spindle.

The Model G0704 drawbar will extract the

arbor from the spindle. Once the arbor or

collet has broken free from the spindle

taper, be sure to properly support it while

continuing to loosen the drawbar. failure

to properly support the arbor or collet

while loosening the drawbar will result in

the arbor or collet falling out of the spindle,

causing damage to machine components.

5. slide the tooling upward until it makes con-

tact with the drawbar threads.

6. hand thread the drawbar into the tooling until

the tooling draws up into the spindle taper.

5. protect the table surface with a piece of

cardboard and hold the cutter/tool with a

shop towel to prevent it from falling out of the

collet. Continue loosening the drawbar until

the collet is freed from the spindle.

7. use a 17mm wrench to prevent the spindle

from turning while you use an 8mm wrench

to snug the drawbar.

Note: Do not overtighten the drawbar.

Overtightening makes collet removal difficult

and will damage the drawbar threads, collet,

and the spindle taper. Keep in mind that the

taper keeps the collet and tool in place. The

drawbar simply aids in seating the taper.

To tilt the headstock to the left or right:

Headstock Travel

(z-Axis and Rotation)

1. disConneCt mill/drill From poWer.

headstock height is adjustable in the vertical

z-axis to accept large workpieces. For unique

milling operations, the headstock can be tilted

right or left between 0° and 90°.

During the following steps, be aware that the

headstock is top-heavy and will swing if it is

not well supported once the center bolt and

lock nut are loosened. Always support the

headstock with one hand when loosening

these fasteners. failure to do so may result

in unexpected movement of the headstock,

causing damage to the machine and per-

sonal injury.

To raise or lower the headstock:

1. unlock the vertical travel lock levers shown in

figure 29.

Table Travel

X-axis handwheels

the mill/drill table can be moved in the longitudi-

nal (X-axis) and cross (y-axis) directions.

Longitudinal feed

the X-axis is moved by the handwheels shown

in figure 31 at the end of the table. these

handwheels will move the table in both directions

side-to-side. one complete revolution of either

handwheel moves the longitudinal feed 0.100".

there is also a scale on the front of the table for

use when a tight tolerance is not required. the

longitudinal feed can be locked in position by

table locks located on the front of the table (see

figure 32).

To adjust the headstock gibs:

Gibs

1. disConneCt mill/drill From poWer!

gibs are wedge-shaped pieces of metal that

fill the gap between the sliding surfaces of the

machine. by adjusting the position of the gib in

its gap, you can remove any play that might exist

between the adjacent components. the gibs are

pre-adjusted at the factory but due to storage,

break-in, and usage, may require adjustment. if

movement seems too tight at first, make sure that

all the rust preventative that was shipped on the

machine is removed from the ways. lubricate the

ways with oil, and work the table back-and-forth

several times until the movement is easier.

2. remove the two screws that secure the top

end of the way cover, pull it down to expose

the lower gib screw, then loosen the vertical

To adjust the y-axis leadscrew nut:

Leadscrew backlash

1. locate the leadscrew nut underneath the

table through the hole in the base under the

rubber way cover.

When you turn the handwheels to adjust the posi-

tion of the table, you will notice slight play (back-

lash) in the handwheel before the table begins to

move. if this play is greater than 0.008" (measured

with the dial at the base of each handwheel), then

you will need to adjust the leadscrew nuts.

2. tighten the adjustment screws on the

leadscrew nut in the same manner as

described for the X-axis leadscrew adjust-

ment.

to reach the adjustment screws on the leadscrew

nut, you may have to fabricate extensions for

your hex wrenches. When adjusting, make adjust-

ments in small increments. attempting to reduce

backlash to less than 0.003" is impractical and

will add unnecessary wear to both the leadscrews

and the leadscrew nuts.

3. test the adjustment by turning one of the

cross handwheels. the ideal amount of play

when properly adjusted is 0.003"–0.006".
