THE

HEAD.

The

cuEterhead

motor,

Fig,

1,

is

built

directly

onto a

nickel

chrome

steel

spindle

which

runs

on

precision

high

speed

bearings.

Blower

"B"

is

incorporated

in the

head

to

dislodge

chips

from

the

face

of the work.

Transparent

guard

"C",

which

can

be

swung

a way

for

easy

access

to the

cutter,

gives

full

protection

to

the

operator

without

obstructing

his

view

of

the job. A

quick

acting

brake

and

also a spindle

lock

for

use

when

cutter

changing

are

incorp-

orated.

The

brake

is

operated

by

pressing

the knob "Dti

after

the

motor

has

been

switched

off.

The

lock

is

operated

by

sliding

the

lOCking

bar,

tiE

tI

, INWARDS to

lock

the

spindle

and

OUT

to

unlock.

Care

should

be

taken

not to

start

the

machine

whilst

the

locking

bar

is

in

position.

MOVEMENT

OF

THE

HEAD.

The

head

is

brought

down

and

locked

by

means

of the fa

at

treadle

(see

Fig.

II). A

touch

on

the

auxiliary

toe

pedal

disengages

the

ratchet

holding the

head

which

is

counterbalanced

so

that

it

rises

out

of the

work

automatically

The

travel

of the

head

is

limited

by

stops

for

movement

both

up

and

down. A

range

of

four

stops,

"G",

controls

the

downward

movement.

Anyone

of

these

stops

may

be

selected

by

means

of the hand

lever

"J",

A

long

stop

screw

"H"

gives

a

wide

range

of

movement

to the head.

The

upward

movement

of

the

head

is

controlled

by

an

adjustable

stop

"K",

To

reduce

the

travel

of

the

head the

locking

handwheel

"M"

is

first

loosened

and

the

stop

then

screwed

in a

clockwise

direction,

the

locking

handwheel

being

tightened

again

afterwards.

To

increase

the

travel

of the

head

the

stop

is

screwed

in

an

anti-

clockwise

direction.

The

table

can

be

supplied

in two

forms,

either a plain

table

as

Fig.

2,

or

one

with

compound

movements

as

illustrated

opposite.

For

general

routing

operations

using

jigs

with

shaped

formers

or

templates a plain

table

is

recommended.

When

heavy

cuts

are

required

where

it

is

necessary

to

clamp

the

work

to the

table

for

straight

work,

the

compound

table

is

ideal

using

the

longitudinal

and

transverse

movements.

It

is

not

possible

to

change

the

tables

after

the

machine

is

despatched.

Both

tables

have a removable

centre

plate

to

allow

the

cutter

to

work

below

the

surface

when

moulding,

etc. A series

of

holes

in the

tables

are

for

securing

fences,

for

straight

cutting

such

as

edge

moulding.

FORMER

OR GUIDE

PIN.

The

rO\lting

of

all

kinds

of

shaped

work

is

done

with

jigs,

the

cutter

reproducing

the

shape.

A

formed

shape

or

template

is

attached

to

the

underside

of

the

jig

and

is

worked

round a pin

proj

ecting

through

the

table

a$

shown

on

page

14

and

subsequent

pages.

The

pins

are

reversible

in the

plain

table,

each

end

being

made a different

size

to

correspond

with

the

diameter

of

the

cutter.

The

lever

"C",

Fig.4

(see

also

page

12)

gives

three

heights

of

the

pin

above

the

table

to

allow

for

different

depths

of

cut

or

sinking.

To

change

the

pins,

slacken

handle

"B"

on

holder

"D".

The

pins

are

The

bearings

are

lubricated

by a

patented

system

of

oil

mist

lubrication

and

therefore

it

is

important

to

use

the

oil

and

to

lubricate

the

bearings

to

instructions

given

on

page

5.

Since

the

introduction

of

our

patented

system,

the

special

high

speed

ball

bearings

(which

must

be

purchased

from

Wadkin

Ltd.

) have

given

exceptional

performance,

but

as

no

guarantee

can

be

given

against

bearing

failure

which

could

be

attributable

to

over

lubrication

or

other

causes,

it

is

recommended

that

the Head

is

returned

to

us

for

repair.

We

have a Service

Department

where

the

work

is

undertaken

with

the

minimum
delay.
Where

machines

are

shipped

abroad

this

service

arrangement

cannot

economi-

cally

be

given.

Under

these

circumstances'

a

description

of how to

dismantle

the Head

is

given on

page

CUTTER

GRINDING

To

obtain

consistently

good

work

from

high

speed

routing

it

is

essential

that

the

cutters

are

kept

sharpened

and

ground

correctly.

This

can

only

be

assured

when

suitable

equipment

is

available.

The

ideal

grinder

for

this

purpose

is

the

Universal

Type

N.

H.

shown left. Not only

will

this

machine

deal

with

all

router

cutters,

but

it

is

indispensable

for

maintaining

every

type of

cutter

equipment

used

in a woodworking

plant,

excluding

long

planer

knives.

NOTE -

Where a suitable

grinder

is

THE

IMPORTANCE

OF

MACHINE

GRINDING.

The

key

to

high

quality

rouling

is

Cl

cutter

wilh clea:n

sharp

edges

and

smooth

continuous

relief.

In

order

to

maIntain

the

correct

cutting

angle

and

clearance,

machine

grinding

is

essential.

Experience

has

shown

that

free-hand

grinding

does

not

give

the

clean

smooth

edge

essential

for

good

cutting,

and

the

result

is

nothing

like

the life of a

machine

ground

cutter.

Another

import-

ant

point

is

that

it

is

almost

impossible

to

gr

ind

equal

amounts

from

both

edges

free-hand.

Mechanical

grinding

ensures

that

both

edges

of a

cutter

are

identical,

also

the

minimum

amount

of

metal

is

removed

at

each

regrind,

thus

making

sure

of

longer

life

from a cutter

than

when

most

carefully

free-hand

ground.

With the

most

types

of

for both

metal

can

be

dealt

with.

and

the

For

slacken

off

the

STONING

OF

CUTTERS

After

grinding,

the

cutter

must

be

stoned

up

before

using

to

remove

the

ragged

edge.

This

is

done by

using

a No. 183

or

177

Carborundum

slip

stone

dipped

in

paraffin

and

applied

td the

edge

of the

cutter

as

shown below. (Stones

are

illustrated

on

Page

47).

Correct

stoning

can

only

be

achieved

by

practice,

but

most

operators

have

no

difficulty

with

this

operation

after

a few

weeks

experience. A reliable

guide

as

to

whether

the

cutter

has

been

properly

stoned

will

be

that

the

job

will

almost

feed

itself,

instead

of

requiring

force

in

feeding

past

the

cutter.

In

addition

to

stoning

after

grinding,

the

cutter

will

need

restoning

between

regrinds.

The

length

of

time

the

cutter

will

retain

its

edge

will

depend on the

material,

and

may

vary

between

half

an

hour

and

. two

hours

or

more.

Here

again,

the

effort

required

to

feed

the

work

is

the

best

indication

of

the

condition

of

the

cutter

and

whether

stoning

is

required.

Stoning

for

half a minute

should

be

sufficient

and

the

cutter

should

stand

between

four

and

eight

restonings

between

regrinds,

depending

on the

skill

of the

operator.

TYPICAL QUESTIONS

AND

ANSWERS

ON

WOOD

ROUTER CUTTER SHARPENING.

Is a c'utter

as

despatched

by the

makers

ready

for

use?

No.

It

requires

honing

or

stoning

before

being

used.

The

cutters

are

sent

out

as

they

leave

the

Grinding

Machine.

They

are

not

stoned

up

at

our

Works

as

the

edge

may

be

damaged

in

transit.

Is

the

use

of a slip

stone

necessary

on

router'

cutters?

Yes.

All

cutters

should

be

honed

before

using

on the

Router.

The

sharper

the

cutter

the

better

the

finish

and

the

faster

the feed.

What

sort

of

should

be

used,

and

and

the

method

Pages

54-55.

How

often

should

the

cutter

be

honed?

This

depends

on the

timber

being

cut.

Stringy

timber

may

require a stone

on the

cutter

every

20

minutes,

while

on

clean

straight

grain

wood the

cutter

may

run

for

an

hour.

When

does

a cu

tter

need

sharpening?

When

the

work

is

difficult

to

push

past

the

cutter,

or

when

the

finish

is

not

clean

and

smooth,

the

two

characteristics

generally

go

together.

When the

cutter

is

sharp,

the

work

will

almost

feed

itself.

What

determines

whether a panel

cutter

should

be

ground

in the

flute

or

on

the

relief?

The

general

practice

is

to

grind

in

the

flute,

as

shown

on

Page

and

continue

to do

so

until

In

are

quite

suitable

for

claim

to

obtain

improved

performance

by

sl1ghtly

modifying

the

profile

of the

cutter

to

suit

the

particular

specification

of

metal

which

they

are

cutt-

ing.
These

modifications

may

be

regarded

as

refinements

and

should

not

be

attempted

until

the

HOW

TO

TELL

WHEN A METAL

WORKING

CUTTER

NEEDS

RE-GRINDING.

The

first

thing a

rruting

machine

operator

should

know

is

how to

tell

when the

cutter

is

sharp

and

working

correctly.

The

answer

is

that

when the

cutter

is

right,

the

chips

will

leave

the

cutter

bright

and

curly,

and

the

feed

will

be

so

easy

that

the job

almost

feeds

itself.

When

these

conditions

exist

the

cutter

will

have

a long

life

between

grinds.

If

the

cutter

is

incorrect

ly

ground,

the

chips

will

come

off in

straight

shreds,

and

an

excessive

amount

of

force

will

be

needed

to

push

the job

past

the

cutter.

Good

work

is

out of

the

question

under

such

conditions,

and

there

is

always

the

danger

of

pushing

the end off the

cutter.

If

the

cutter

is not

working

correctly,

stop

the

machine

immediately

and

find

out

why.

To

ensure

the

maximum

life

of the

cutter,

and

at

the

same

time

obtain

free

cutting,

it

is

essential

that

the

cutter

is

kept

efficiently

lubricated.

Always

use a lubricant

consisting

of a

mixture

of

paraffin

and

lard

oil.

The

simplest

method

of

application

is by

brushing

the

lubricant

on to

each

blank

before

clamping.

The

lubricant

need

only

be

applied

on the

sheets

in the

track

of

the

cutter.

THE

IMPORTANCE

OF

MACHINE

GRINDING.

Wadkin

metal

working

router

cutters

(except

special

purpose

cutters)

are

supplied

with two

spiral

cutting

edges,

as

shown

in the

sketch

below.

Cutting

Edge

Cj

!j-~

7\fJ

Cutting

Edge

All

metal

cutting

router

cutters

have

one

edge

ground

back

.010.

This

is

done in the

formed

relief

grinding

so

that

the

normal

re-grl.nding

in the

flutes

of

the

cutter

will

not

be

affected.
In

order

to

preserve

the

cutting

diameter

resharpening

is

done by

regrinding

the two

spiral

flutes

equally.

Expe

rience

has

shown

that

free

hand

grinding

does

not

give

the

clean

smooth

throat

essential

for

chip

clearance

and

good

cutting

and,

in

consequence,

gives

nothing

like

the

life

between

grinds

that a machine-ground

cutter

gives.

Another

important

point

is

that

it

is

almost

impossible

to

grind

equal

amounts

from

both

edges

free

hand.

By

resharpening

by

mechanical

means,

not

only

is

accurate

grinding

ensured,

with

both

edges

of

the

cutter

ground

iden-

tically,

but

the

minimum

amount

is

removed

from

the

cutter

at

each

regrind,

ensuring a longer

life

than

TYPICAL

QUESTIONS

AND ANSWERS ON

METAL

CUTTER

SHARPENING.

Is a cutter

received

from

the

Stores

re?dy

for

use?

No.

It

requires

honing

or

stoning

before

use.

The

cutters

are

sent

out

as

they

leave

the

Grind-

ing

Machine.

They

are

not

stoned

up

at

Qur

Works,

as

the

cutting

edges

would be

damaged

in

transit.
Is

it

permissible

to

use

an

oil

stone

on the

outside

of the

cutters

when dull ?

This

is

the

essence

of

routing

and the key

to

high

performance.

As soon

as

the

cutter

begins

to

drag,

stop

the

machine

and hone

up

the

cutter

on the

outer

edges

until they

are

sharp.

This

can

easily

be done in

half

a minute and the

method

is

iilustrated

on

pages

54

and

55.

How

often

should a metal

working

cutter

be

stoned?

About

every

hour.

On

hard

material

it

may

be

every

half

hour.

On

some

soft

materials

every

two

hours,

but

on

aluminium

and

alclad

sheets

it

pays

to

keep the

cutter

sharp

to

prevent

pack-

ing on the

cutter.

How

many

times

should a cutter

be

stoned

between

regrinds?

A

cutter

should

stand

four

to

eight

stonings

depending on the

skill

of the

operator.

What

stone

should

be

used

and

should

it

be

used

dry?

A No. 183

Carborundum

Slip Stone. Dip the

stone

in

oil

and

paraffin

to give the

best

results.

Should the

cutters

be

used

dry

on

metal?

No. Always

use a lubricant

consisting

of

paraffin

and

lard

oil,

mixed

and

applied

to the

sheets

by

brush

only a

thinner

the

lard

,

oil,

and

only enough for the

purpose

should be

used.

Excessive

paraffin

causes

a blue

smoke

when cutting.
What

causes

metal

chips

to

pack on the

cutter?

Generally,

blunt

cutters.

The

wrong

shape

of

cutter,

especially

on

aluminium

and

alclad

sheets

will

cause

it,

also a lack

of

lubricant.

What

causes

chips

to {Jack in the guide

h\lsh?

Blunt

cutters.

They

make

shreds

of

swarf

which

work

up into the

bush

and

weld

to

the

shank.

If

the

cutter

is

correct

the

large

curly

chips cannot

possibly

get

into the

small

clearance

between

cutter

and guide bush.

What

causes

shudder

when

cutting?

The

cutter

has

not

been

stoned.

The

rough saw edge

left

by

the

grinding

wheel

causes

it.

To

cure

TYPICAL

QUESTIONS ANO ANSWERS -

Continued.

Can

the

loss

of

diameter

due

to

cutter

wear

be

compensated

for?

Yes.

All

Fixed

Head

Routing

Machines

are

now

sent

out

with a

range

of

graded

pins

.005",

. 010", . 015", . 020" on

all

sizes.

On

the

Radial

Machine,

undersized

guide

bushes

can

be

supplied.

What

is

the

feed

speed

on the

Router?

Feed

as

fast

as

the

cuttH

will

take

it.

If

the

cutter

is

sharp

the job

will

almost

feed

itself

and

will

only

require

guiding.

If

the job

needs

pushing

the

cutter

is

not

sharp.

On

metal,

a good

speed

on

straight

work

is 4 inches

per

second.

On

intricate

shapes,

it

is

impossible

to

feed

at

this

speed,

and

the

limitation

is

the

speed

at

which

the

operator

can

manipulate

the

job,

generally,

1 to 2

inches

per

second.

Can

sheet

steel

be

routed?

No,

only

non-ferrous

metals

such

as

Alclad,

Dural,

Aluminium,

Brass,

Copper,

Lead.

Not

Bronzes,

2incs

or

Tin.

TUNGSTEN CARBIDE

TIPPED

ROUTER

CUTTERS.

As a

general

rule,

tungsten

carbide

cutters

should

only

be

used

when high

speed

steel

cutters

will

not

stand

up to

the

hardness

of

the

material

being

routed.

They

are

not

suitable

for

ordinary

timbers

and

will not

cut

half

as

cleanly

as

high

speed

steel

on

wood.
Tungsten

carbide

cutters

are

necessary

on

the

following

materials

:-

Resin

bonded

plywoods,

wood

pulped

board

and

wall

board,

plastics

such

as

Holloplast

and

Catalin.

Linen

and

paper

based

materials,

such

as

Tufnol

and

Elephantide.

Aluminium

alloys,

die

cast

or

wrought,

containing

silicon

or

manganese

(there

are

certain

high

silicon

alloys

which

are

too

hard

even

for

tungsten

carbide

on

the

router).

All

sand

cast

aluminium

castings.

SHARPENING

TUNGSTEN

CARBIDE

ROUTER

CUTTERS.

Tungsten

carbide

cutters

cannot

be

sharpened

with

ordinary

grinding

wheels

or

honed

with

Carborundum

honing

stones.

The

grinding-

can

be

done

on

the

N. U.

Grinder

and

S.

F.

A.

Attach-

ment

described

on

pages

45

-46,

using

grinding

wheels

86R

and

87R

describe~

on

page

46.

Use

the

wheels

dry;

86R

for

roughing,

taking

very

light

(uts,

and

expect

to

take a long

time

remov-

ing a small

amount

of

carbide.

Finish

grind

dry,

using

wheel

87R.

In

order

to

get a good

cutting

edge

it

is

necessary

to

machine

lap

with

wheel

No.

145.

This

wheel

is

made

from

soft

material

and

its

cutting

edge

is

impregnated

with

diamond

dust

It

is

expensive

to

use

and

should

be

used

for

final

finishing.

It

('an,

of

course,

be

used

for

grinding

in

place

of

the

f.6R

and

87R

wheels,

but

the

wear

and

cost

of

the

laps

would

be

prohibitive.

Never

attempt

to

true

the

diamond

lap.

When

using

the

machine

lap

smear

the

face

of

the

wheel

with

oil

and

then

take

the

lightest

possible

cuts

to

get a polished

face

and a clean

edge.

Finish

the

cutting-

edge

with a hand

lap,

which

is

also

impregnated

with

diamond

dust

and

is

illustrated

on

page

47.

The

best

method

of

using

the

hand

lap

is

to

immerse

the

lap

and

tool

under

water

and

hone

in

this

position.

This

is

recommended

so

that

the

diamond

dust

freed

from

the

lap

floats

to

the

surface

of

the

water

and

does

not

be('ome

abrasive

between

the

cutter

and

the

lap,

causing

excessive

wear

on

the

lap.

If

this

is

not

possible,

use

as

much

water

as

possible

to

swill

off

the

diamond

dust.

The

general

instructions

on

stoning

cutters

on

pages

54-55

apply

to

tungsten

carbide

cutters

except

that

the

diamond

lap

is

used

instead

of

the

Carborundum

stone.

Tungsten

carbide

cutters

sent

out

from

our

Works

require

honing

with

the

hand

lap.

CONCERNING

CUTTER

COLLETS.

Never

over-tighten a collet.

The

short

spanner

or

screw

key

provided

is

designed

to

give the

maximum

grip,

when

used

by the

average

operator.

The

use

of a

pipe

wrench

strains

the

collet

and

actually

reduces

the

grip

on the

cutter.

Never

allow

cutters

to

project

from

the

collet

more

than

is

absolutely

necessary.

It

is

a golden

rule

that

the

nearer

the

cutter

to

the

collet,

the

better

the cut and the

longer

the life of the

cutter.
