Machining

under

MICROFIN

"superfinish"

conditions

(fig.

1)

The

various

settings

suitable

for

different

machining

purposes

are

indicated

in

the

manual

"TECHNOLOC";Y".

When

in

doubt,

please

refer

to

this

manual.

The

parameters

relative

to

"superfinish"

MICROFIN

machining

operations

will

be

found

in

chapter

2

of

the

MICROFIN

procedures

descr~bed

in

the

"TECHNOLOGY"

manual.

Switch

on

the

equipment

by

~sing

the

following

control

switches

:

(821)

(822)

(823)-

(824).

The

required

polarity

of

the

electrode

is

obtained

by

setting

the

selector

switch

(825)

to

the

left-

or

right-

hand

position

for

MICROFIN

operation.

Negative

polarity

is

that

most

commonly

used.

Choose

the

mode

of

injection

by

means

of

selector

switch

( 8 3

7)

•

Switch-on

the

machining

power

by

means

of

push-button

(832).

NOTE

:

It

is

possible,

if

necessary,

to

modify

the

operating

characteristics

of

RLC

"superfinish"

circuit

for

particular

machining

operations

(fig.

2)

By

insertion

of

a

resistor

between

terminals

(804),

after

having

removed

the

bridge

(805).

By

connecting

a

capacitor

across

terminals

(806),

after

having

disconnected

the

capacitor

-

inside

the

generator

-

factory

mounted

across

the

internal

tags

of

terminals

(806).

The

latter

capacitor

can,

subsequently,

be

mounted

externally.

Machining

under

"pulsated"

working

conditions

(fig.

1)

Both

the

ISOPULSE

and

the

MICROF!N

machining

processes

can

be

carried

out

under

"pulsated"

working

conditions.

Set

the

"pulsator"

switch

(830)

to

position

(I)

•

Adjust

the

machining

time

by

means

of

potentiometer

(829).

Adjust

the

withdrawal

time

of

the

electrode

by

means

of

potentiometer

(828).

Operation

of

the

rotary

spindle

(fig.

3)

If

a

rotary

spindle

attachment

is

incorporated

in

the

machine,

it

can

operated

in

the

following

manner

:

To

start

operation

of

the

spindle,

clockwise

rotation,

set

the

selector

switch

(847)

to

position

(1).

To

start

operation

of

the

spindle,

counter-clockwise

rotation,

set

the

selector

switch

to

position

(2).

Free

running

operation,

set

the

selector

switch

(847)

to

position

(3).

Both

the

speed

and

the

direction

of

rota-

tion

of

the

spindle

are

controlled

by

means

of

potentio-

meter

( 8 4

8)

.

All

the

above

operating

modes

of

the

rotary

spindle

take

place

when

switch

(846)

is

set

to

~osition

(I)

. When

switch

(846)

is

in

position

(0),

the

spindle

is

inoperative.
