INTRODUCTION

Your

Monarch

lathe

will

produce

more

and

bet-

ter

work with

less

operator

fatigue.

It

has inbuilt

precision

of

the

kind which

has

made

Monarch

the

accepted

standard

in

the

lathe

field

for

many

years

.

It

is

provided

with

the

nigher

speeds

and witlr the

ease

of

operating

effort

so

necessary

for

maximum

productive-

ness

.

Give

your

Series

61

the

care

which a

precision

tool

deserves.

Follow

the

suggestions

and

in-

structions

contained in

this

handbook and you

will

be

rewarded

by

superlative

performance

over

the

years.

RECEIVING

AND

CLEANING

After the

lathe

has

been

uncrated

down to

the

sk

i

ds,

remove

the

packing

list

from

the

parts

box and

check

the

shipment.

Any

shortage

or

discrepancy

found should be

reported

immedi

-

ately

to

The

Monarch

Machine

Tool

Company,

Sidney, Ohio. Always, when

referring

to

the

machine,

mention

the

serial

number.

This

is

stamped

on

the

identification

plate

attached

to

the

front

of

the

headstock.

The

lathe

should

re-

main

on

the

skids

until

it

is

moved

as

close

as

possible

to

the

point of

installation.

From

the

time

the

lathe

is

uncrated

until

all

of

the

"anti-rust"

compound

is

removed

none of

the

working

parts

such

as

the

carriage,

tailstock

and

levers

should be moved.

The

vigorous

ap-

plication

of a

brush

and a

suitable

solvent

re-

moves

this

compound quickly.

After

the

lathe

has

been thoroughly

cleaned

apply a thin

film

of

oil

to

the

bed

ways.

LIFTING

Be

sure

to

exercise

great

care

when lifting and

moving

the

machine.

Serious

damage

can

result

if

the

lathe

is

dropped

or

the

leadscrew

and

con-

trol

rods

at

the

front

of

the

bed

are

bent.

CAUTION:

Be

sure

to

select

cables

with

suffi-

cient

strength

for

the

job, and

al-

ways

balance

the

load

before

lifting.

ease

which

has

been

built

into

the

Monarch

Series

61

and

to

avoid

damage

,

the

operator

should

familiarize

himself

completely

with

the

functions

of

the

var-

ious

controls.

These

are

explained

mechanism

by

me

c

hanism

in

the

section

which

follows.

HEADSTOCK

On

the

sitions

. Note, by

referring

to

the

c

hart,

that

the

short

period

of

experience

familiarizes

the

operator

with

the

controls,

he

may

stand

at

CARE

AND

ADJUSTMENT

The

proper

care

and

adjustment

of

your

Monarch

lathe

is

very

important

for

maintaining

the

ac-

curacy

and

ease

of

operation

which

have

been

carefully

designed

and

built

into

the

machine

A

good

machinist

is

judged

by

the

appearance

and

condition

of

the

tools

with

which

he

works.

The

Monarch

Series

61

has

a

very

fine

finish

which

is

easy

to

keep

clean.

Occasional

wiping

with

a

clean,

dry

cloth

or

solvent

soaked

cloth

will

keep

the

finish

looking

bright

and

new

for

a

long

while.

All

adjustments

are

expertly

made

at

the

factory

before

shipment

of

the

machine

.

Occasionally

,

however,

certain

further

adjustments

may

have

to

be

made.

The

longitudinal

feed

friction

clutch

is

adjusted

by

turning

screw

(A),

Figure

13,

either

in

or

out

so

the

lever

is

moderately

tight

about

halfway

down

toward

the

apron

from

the

neutral

position

shown.

The

cross

feed

friction

clutch

is

simi-

larly

adjusted

by

means

of

screw

(B).

Screws

(C)

and

(D)

are

for

adjustment

of

the

cross

feed

slide

and

compound

slide

gibs.

There

is

a

similar

screw

adjustment

at

the

rear

of

each

slide.

The

gibs

should

be

adjusted

to

give

-

a

slight

drag

to

the

slides

. If

the

adjusting

sc

rews

are

drawn too tightly

against

each

end of

the

gibs, they may

create

a bad

bearing

surface

by

throwing

the

gibs

out of line.

LUBRICATION PROCEDURE

PREPARATION

FOR

OPERATION

AND

RUN-IN

When you

first

receive

your

Series

61

lathe,

you

will

find

that

an

anti-rust

compound

has

been

applied

to

all

outside

machined

surfaces

.

After

removing

the

compound

as

suggested

in

the

section

on

receiving

and

cleaning

(Page

3)

apply

a

thin

film

of

medium

grade

oil

to

bedway

surfaces.

Since

the

machine

is

shipped

without

oil

in

the

head-

stock

,

gear

box

or

apron

,

these

reservoirs

must

be

filled

to

proper

levels

with

the

recommended

types

of

lubricant.

Each

reservoir

has

an

individual

oil

level

gage.

The

lathes

should

then

be

thoroughly

oiled

and

greased

throughout

according

to

the

lub-

rication

charts

on

page

14.

A few

extra

precautions

taken

during

the

first

few

weeks

of

operation

of

the

lathe

will

pay

dividends

in

the

life

of

the

ma

c

hine

.

Complete

removal

of

all

anti-rust

compound

cannot

be

stressed

to

strongly.

Although

over

-lubri

cation

is

never

recommended,

special

care

should

be

exercised

also

to

assure

full

lubrication

wherever

specified

,

from

the

very

first

moment

of

operations.

It

is

also

desirable

to

avoid

maximum

speed

,

feed

and

depth

of

cut

during

the

first

few

days

of

continuou

s

operation.

Following

the

operation

of

the

lathe

for

the

first

90

days,

or

approximately

750

hours,

it

is

always

a

good

practice

to

drain

all

lubrication

reservoirs,

flush

(preferably

with

a

light

clean

flushing

oil)

and

then

refill

to

the

proper

level

with

the

recommended

lubricant.

PERIODIC OIL

LEVEL

CHECK

Oil

reservoir

levels

sh

ould be

checked

at

least

twice

a

week.

CAUTION:

Turn

off

the

main

drive

motor

when

checking

oil

reservoir

levels.

On the

oil

gage

for

each

unit

is

a

line

which

indicates_

t

he

correct

oil

level.

Never

permit

the

level

to

fall

very

far

below

this

line

as

lack

of

lubrication

can

result

in

damage

to

the

machine

in

a

relatively

short

period

of

time.

Over-filling

should

also

be

avoided

since

it

results

in

oil

wastage

and

may

cause

a

cer

-

tain

amount

of

over-heating

due

to

excessive

turning

of

the

oil.

REQUIRED

OIL CHANGES

It

is

recommended

that

once

every

six

months

the

oil

be

drained

from

the

reservoirs

and

that

they

be

flushed

with

a

light

clean

flushing

oil

and

then

re-

filled

to

the

proper

level.

At

the

same

time

the

apron

and

headstock

lubricating

pumps

should

be

inspected

and

cleaned.

These

pumps

are

small

self-

contained

,

non-adjustable

piston

pumps

installed

in

individual

reservoirs.

The

pump

stroke

is

set

at

the

factory

to

satisfy

normal

operating

conditions.

No

change

should

be

attempted

unless

the

operation

of

the

machine

indicates

a

definite

necessity.

A

filter

disc

at

the

pump

inlet

protects

the

lubricat-

ing

system

from

chips,

dirt

and

other

foreign

sub-

stances.

It

is

recommended

that

when

the

pump

is

inspected

every

six

months

this

disc

be

replaced.

When

adding

fresh

oil

take

every

precaution

that

no

dirt

or

chips

are

permitted

to

contaminate

the

res-

ervoir

since

such

foreign

matter

can

quickly

clog

the

filter

discs

of

the

pumps

and

impair

their

proper

operation.

Also

it

is

important

never

to

use

lubri-

cants

that

contain

compounds

that

might

be

absorbed

by

the

filter

discs

thus

clogging

and

reducing

the

delivery

of

oil

through

the

system.

The

reason

so-

called

"dripless"

oils,

or

grades

containing

graphite

,

soap

or

other

foreign

substan

ces

should

not

be

used.

In

the

case

of

the

Series

61

apron

with

power

rapid

traverse

the

apron

pump

can

be

reached

by

remov-

ing

the

pump

cover

from

the

front

of

the

apron

just

behind

the

apron

handwheel.

In

the

case

of

the

Series

61

with

plain

apron,

it

is

necessary

to

remove

the

bottom

cover

from

the

apron

in

order

to

reach

the

lubrication

pump.

To

remove

the

headstock

lubrication

pump

it

is

nec-

essary

to

remove

the

right

angle

plate

from

the

back

of

the

headstock.

This

exposes

the

pump

and

per-

mits

its

removal

for

inspection

and

c

leaning

.

CORRECT

HAND

OILING

Before

the

lathe

is

started

each

working

day

all

oil

cups

and

hand

oiling

points

should

be

oiled

accordi

_ng

to

the

lubri

cation

charts

on

page

14.

The

use

of

the

pneumatic

type

oil

can

with

plunger

operation

,

rather

than

the

ordinary

spring

bottom

type,

is

recommended

since

it

permits

better

oiling

at

many

points

and

gives

better

contro

l

over

quantity

of

oil

used.

USE

OF

GREASE

GUN

Be

sure

to

eliminate

air

pockets

by

operating

the

gun a few

times

before

using

.

Be

sure

to

clean

all

grease

fittings

before

using

grease

gun.

Be

careful

not

to

over-lubricate

since

the

high

pres-

sure

exerted

by a

grease

gun

may

cause

over-filling

of

the

bearings

or

damage

to

seals.

IMPORTANCE OF CLEANLINESS

It

is

extremely

important

that

lubricants

and lu

bri

-

cant

containers

be

handled

carefully.

Careless

ling

c

an

qui

.

Cleanliness

is

primarily

a

systemati

c

handling

and

proper

storage

facilities

which inc

lade

well

marked

containers

used

for

the

same

lubricant

at

all

times.

The

following

suggestions

will

be

helpful

in

main-

taining

the

cleanliness

of

the

lubrication

system:

1.

Wipe

all

filter

openings

before

adding

oil.

2.
