HANDLING

OF

THE

ACCESSORIES

The

accessories

have

been

designed

with

the

utmost

regard

to

simplici

of

utilization,

therefore,

no

difficulty

should

be

encountered

in

their

handling.

Nevertheless,

the

following

remarks

concerning

handling

of

the

rotary

spindle

and

the

tapping

attachment

may

be

found

useful.

Rotary

spindle,

type

AC-3

The

rotary

spindle

can

be

fastened

either

to

the

magnetic

chuck

(902)

,

to

the

mechanical

chuck

(901),

or

directly

to

the

piston

(fig.

1 a &

b).

In

the

first

two

cases,

thoroughly

clean

the

contact

and

the

reference

surfaces

of

both

the

chuck

and

the

rotary

spindle

and

fasten

the

spindle

to

the

chuck

as

if

it

were

an

electrode

holder

(fig.

1

a).

Lock

the

rotary

spindle

to

the

chuck

by

means

of

the

clamping

hook.

In

the

third

case,

fasten

the

brace'

(948)

to

the

rotary

spindle

and

then

attach

this

assembly

to

the

piston

by

means

of

the

screws

provided

for

this

purpose

(fig.

1

b).

Connect

the

power

supply

cable

of

the

motor

of

the

rotary

spindle

to

the

appropriate

socket

on

the

generator

(fig.

2

a);

the

spindle

will

then

revolve.

If

a

separate

control

unit

is

available

for

the

tapping

attachment,

the

connection

should

be

made

as

illustrated

in

fig.

2

b.

The

rotary

spindle

will

then

revolve

as

soon

as

power

is

switched

on

by

means

of

the

switch

located

on

the

control

unit;

the

selector

switch

should

be

set

to

position

3,

i.e.

full

right.

Both

the

direction

of

rotation

and

the

speed

of

the

spindle

can

be

controlled

the

knob

provided

for

this

purpose.

Tapping

attachment

This

attachment

is

to

be

fastened

to

the

shoulder

of

the

rotary

spindle

(fig.

a

clamping

screw

is

provided.

The

disposition

of

the

various

parts

of

the

unit

(lead

screw,

nut,

etc

••••

)

is

illustrated

in

fig.

The

3

selector

swi

located

on

the

control

panel

or

on

the

control

unit

of

the

rotary

spindle

makes

provision

for

either

left-

or

right-hand

threading,

the

third

position

being

reserved

for

use

of

the

rotary

spindle

(see

fig.
