SECTION 1. INITIAL SET-UP

LOCATION

Erecting drawings are sent with every machine shipped from

the factory for the assistance of the millwright in setting up the machine.

In setting up, care should be taken to provide ample clearances.

It is sometimes found that a grinding machine must be placed in
a somewhat adverse location. The proximity of railroad traffic, a hard
subsoil condition, or near by machines that set up jarring vibrations will
undoubtedly influence the possibilities of obtaining fine finishes, especially
if a highly reflective surface is demanded. Should the location be one in
which such vibrations are not absorbed by the usual foundation or the
surrounding soil, the foundation drawing blueprint shipped with machines
of 72" work length, give data on a special type of river-bed sand foundation
which has been used with satisfactory results in combating difficult conditions.

UNPACKING THE MACHINE

Care should be exercised in removing the machine from the box
or skid in which it is shipped. All containers, blocking, or skids should be
removed with caution. In the event that heavy tools are used, direct blows
on the container or skids should be avoided, since the accurately constructed
machine might be injured or thrown out of adjustment. The entire shipment
should be checked against the packing list, and any shortage reported at once.
See that no small parts are thrown away, mislaid, or lost.

LIFTING THE MACHINE

The three-point method of lifting should be used. Place slings
around short bars, thrust into the large cast holes in ends of the base and
place a hook under the shelf at the rear of the coolant tank. Hemp rope,
wire rope, or steel chains may be used, with rope being given the preference.
Be sure that kinks or knots do not tend to lift the table or damage any portions
of the machine while lifting.

SETTING UP

Machines of 18", 36", and 48" work length capacity rest on
three pads cast into the base. With the use of steel shims and an accurate
spirit level, shim the pads as necessary in order to level the machine
perfectly in both directions. Use the table top or ways as planes.

i

Machines of 72" work length capacity have adjustable foundation
jack screws. These machines must have a concrete foundation, but do not
grout in base.

I
i

Set the foundation plates furnished with the machine, as indicated
on the blueprint. After placing the machine, remove the tables and with a
sensitive spirit level on the flat way of the base, level the machine lengthwise

and crosswise. Then apply the hold-down screws at the ends of the base.
Relevel with the adjusting screws after the hold-down screws have been

tightened.

ASSEMBLY OF PARTS

Assemble all guards, pipes, and the coolant hose as received

separately with the machine. Refer to the pictures in this manual if

assistance is needed in determining their location.

ELECTRICAL CONNECTIONS

Care should be exercised in making the electrical connections.
This task should be entrusted only to a competent electrician. Refer to the
wiring diagram furnished with the machine.

The operating mechanism of the disconnect switch on the control
panel is interlocked with the enclosure door. The door handle must be in
the "OFF" position before the enclosure door can be opened.

Connect the incoming power lines to the terminals marked

"Customer1 s

and phase. Check for correct wheel motor rotation and if not correct,
reverse two of the incoming line connections.

HEADSTOCK AND FOOTSTOCK

The headstock and footstock should be carefully cleaned. The

spindles of both should be thoroughly wiped out and the centers carefully

inspected. Be sure there are no nicks or burrs on the centers and that
they properly fit their respective holes. Centers must seat well in their
spindles if good results are to be secured.

Never move the headstock or the footstock unless the swivel

table is clean.

WHEEL SHEAVES

Three wheel spindle belt sheaves are supplied, each stamped

with the corresponding wheel size with which it must be used. With the
safety arm rod properly attached to the hinged hood of the wheel guard, a
safety lever will prevent the mounting of any but the proper size belt sheave.

,

First, the wheel should be tapped lightly with a small wooden
mallet or a block to be sure it is of sound structure. Unless a clear ring is
emitted the wheel should not be mounted.
sound, one of the blotters supplied by the wheel maker should be placed on

the sleeve. Then mount the wheel. Do not force it on the sleeve; it should

slide on easily. Now place another blotter on the wheel sleeve flange and
slide this on to the sleeve. Line up the cross-mark on the flange with a
similar mark on the sleeve and insert the screws. Draw the screws up
snugly making sure the wheel is gripped between the blotters. Do not at
first draw one screw up as tight as possible and then the next, also tight.
Take up on the first until it is snug. Then go to the diametrically opposite
screw and draw it up snug. Then draw up the screw 90° from the others
and continue this procedure taking up a little at a time until all screws are

tight. This is important because unless the flange is drawn down evenly

against the wheel, the latter may be cracked. Tighten screws to 15 foot
pounds with all threads free running, clean, and rust free.

WHEEL BALANCING

The grinding wheel should then be mounted in the machine and

the wheel trued. The entire assembled wheel unit consisting of the wheel

sleeve and the grinding wheel should then be mounted on an arbor and placed
in a balancing stand for determination of balance of the unit. Remove the
balancing weights to be found at the center of the wheel sleeve. Allow the
unit to come to rest and chalk mark the wheel on the heavy side (at the

bottom).

unit will come to rest in any angular position. When the wheel is in static

balance, tighten the weights, remount the wheel unit in the machine, and

retrue the wheel.

There are three oil reservoirs to fill; the wheel spindle lubricant,
the hydraulic fluid, and the ways lubricant reservoirs. The wheel spindle
lubricant reservoir is within the wheel spindle housing. Fill this reservoir

with approximately 7-1/2 quarts of 55-85 S.U.V. highest quality oil with
inhibitors for rust and oxidation through the hole for the bayonet gage.

The standard hydraulic fluid reservoir is located inside of the

machine base. Its capacity is approximately 38 gallons. Fill with a high
grade hydraulic fluid of 145-170 S.U.V. to the level indicated on the sight gage,
in the base wall. For the outside hydraulic fluid reservoir which is furnished
as an optional extra, the same hydraulic fluid should be used. Further
instructions will be found on a plate attached to the top of this reservoir.

The ways lubricant reservoir is accessibly mounted on the

rear of the machine.

1

Fill to the level indicated on the sight gage with the lubricant

specified on the instruction plate mounted immediately above, or on, this

reservoir. Approximately 3-1/2 gallons are required.

OILING

Locate all oil holes and cups on the machine and fill with a

medium grade of good machine oil.

GRINDING COOLANT

Whether soluble oil or a paste-type coolant compound is to be
used (mixed with water) see that the coolant mixture is rich enough to
prevent rusting the machine. Coolant tank capacity is approximately 150 gallons.

In selecting the compound to be used as a grinding lubricant,
Norton Company makes no specific recommendation as to manufacture. However,
a compound free from soda is advised. In the event that the compound selected
proves to have an undesirable foaming effect, the addition of a little kerosene

to the coolant will correct this difficulty.

OPERATION EXPERIMENTING

See that all oil and grease cups are filled, and that oil in reservoirs

is at proper levels. Check coolant reservoir.

Before starting the machine, move the wheel slide to its extreme
rear position. Then place the headstock and the footstock at the extreme
ends of the table and centralize them with the grinding wheel. Set the table

reverse dogs so that the table will travel about 6" and the table movement

does not bring either the headstock or the footstock too near the grinding
wheel. Before starting the pump motors be sure that the table start-stop
lever is in the stop position. Naturally, it should be seen that it is in the
stop position until everything is known to be in readiness to run the table.

VISCOSITY RATING

SECTION II. LUBRICATION

V

Lubricating and hydraulic oils, greases and grinding lubricants,
applied in the operating of NORTON grinding machines, should be of a correct
type and good quality. The following information should be valuable to the
user of NORTON machines to get maximum production with minimum down
time

.

To evaluate the physical properties of an oil, the term "viscosity"
is used. This indicates the measured resistance of the oil to flow at a given
temperature and rate. The Saybolt Universal Viscosimeter represents the
U. S. standard means of determining the time in seconds for 60 c.c. of oil
to flow through a standard orifice at a specific temperature. The viscosities

indicated will be identified at 100° F. for simplicity of control.

Identification of the viscosity represented by the S.U. V. at 100° F.

is the abbreviation for Saybolt Universal Viscosimeter.

HYDRAULIC AND CIRCULATING SYSTEMS

Oils for hydraulic and circulating systems must be well refined
to maintain stability of the oil or freedom from oxidation within the limits of
temperature and pressure under which an oil of this type must function. The

residues formed during the oxidation of a petroleum oil are in the form of gum
and varnish which readily disturbs the sensitive valves of a hydraulic control
mechanism. This also might be the cause of plugged pipe lines in the central
lubricating system. The "pour point" of an oil, indicating the point at which
an oil is no longer a fluid, will present a problem only when the equipment is
exposed for long periods of time to low temperatures, or when the new oil in
drums is stored in the open with no physical protection. To assure correct
function of the hydraulic system, a high grade oil, well refined and free from
impurities, must be used.

WHEEL SPINDLE

The lubrication of any grinding wheel spindle is critical to the
successful operation of the entire machine. NORTON Grinders are no
exception to this rule. For spindle oil, we recommend the use of the highest

grade oil with viscosity of 55-85 S.U.V. at 100° F. for use in all NORTON

machines with plain bearings.

5

Spindle oil should be free from any form of contamination, be
stable, and operate with freedom from oxidation. No additives should be
present. The oil should be of good quality and carry the guarantee of a
reputable refiner.

GREASE SELECTION

V

R

>

The selection of the correct grease will be governed by the

speed, temperature, and exposure under which the machine must operate.

Ball bearings at low temperatures require a soft cup grease. High
temperatures require a high grade soda soap grease which possesses a
high melting point. When moisture is present, use a water insoluble
grease. All greases must be stable, in a pure form free from fillers and
of good quality. The grease should be kept free from dirt and all forms of
contamination. In general, bearing manufacturers recommend that a ball

bearing be filled from one-third to one-half capacity and be approximately
maintained at that level. Greases must not bleed in operation. When the
oil bleeds from the soap in a grease, there is the danger that the dried
soap left by the separation will be the cause of mechanical failure.

Stability, therefore, is of extreme importance in grease selection.

OIL DILUTION

The NORTON Type CV-4 Machine is built with various hydraulic

operating valves which require clean hydraulic oil of good quality in order

that they all may operate satisfactorily.

As nearly as possible, care has been taken to prevent coolant

splash, spray, or mist from entering the hydraulic reservoir which would

tend to form a harmful emulsion or sludge.

If, however, the oil takes on a yellow appearance, the indications
are that some coolant has entered the hydraulic system and sooner or later
will cause faulty action of the delicate hydraulic valves.

R
R

R
R

■

R

■

■

In any event, we recommend that the hydraulic and spindle oil

reservoirs be drained and refilled after 500 hours of use.

HYDRAULIC OIL STRAINERS

Machines arranged with the hydraulic fluid reservoir inside the
base have a strainer for the hydraulic fluid located in the suction line of the
hydraulic pump beneath the wheel slide. On machines with the hydraulic

fluid reservoir outside, this strainer is in the tank. These should be checked
periodically to prevent clogging.

SECTION III . DETAILS OF MECHANISMS

TABLE AND TAPER ADJUSTMENT

These machines have a sliding table which travels on the flat and
vee ways of the base, and a swivel table pivoted in the center on top of the
sliding table.

r

%

The swivel adjustment is at the right end of the table and provides
a means for making taper settings. The graduated gib is intended as a guide
only and any finer adjustment may be obtained by the trial and error method
using the adjusting screw at the front.

HEADSTOCKS

Two types of headstocks are available for these machines, one a
dead and the other a live center type. In the dead center type, the center

remains stationary and the work drive plate revolves about it. In the live
center type, the spindle, center, and work drive plate revolve as a unit.

The stopping and starting of the headstock motor is accomplished
automatically. However, if desired this motor may be operated by push buttons
located on a panel at the left front of the machine. A selector switch marked
"Hand-Auto" is provided for this purpose.

Both the dead center and the live center types of headstock are
driven directly through vee belts.

The ball bearings of both dead and live center headstock are
preloaded and prelubricated so that no attention is required.

Headstock center taper is No. 14 Jarno.

FOOTSTOCK

t

*

The footstock usually supplied is the lever type with spring
compression control. The initial movement of the hand lever retracts
the center. A further movement of the lever locks out the center in its
retracted position.

The footstock spindle is clamped by means of a large hand knob
on the front of the footstock body.

Footstock center taper is No. 14 Jarno.

«

Wheel feed is accomplished by a feed screw that meshes with

a cast iron half-nut attached to the under side of the wheel slide. The

screw is mounted in ball bearings and revolves in a bath of oil.

A counterclockwise rotation of the wheel feed handwheel moves
the grinding wheel in towards the work. A positive stop and an indexing
arrangement of the handwheel provide accurate work size setting. By pushing
the indexing knob inwards and rotating it clockwise, wheel feed settings in

increments to provide . 0001" of work diameter reduction up to a total of

. 004", may be selected.

The following table of measurements represents a correlation

of work diameter reductions in both the English and metric systems:

HYDRAULIC AND LUBRICATING PUMP UNITS

These units are on the rear of the machine. The pressure

relief valves'for both the hydraulic and ways lubrication systems are in
the same area. Normally, these valves are set at the factory for the
pressure at which each system should operate. However, metal tags

specifying the correct pressures are attached to each valve. Maintain
ways lubricant pressures at 4 to 6 pounds. Excessive pressure may cause
improper positioning of sliding components.

On the discharge side of both the lubrication and the hydraulic

pumps are filters. These should be checked periodically, and given such
attention as may be necessary. See that the hydraulic filter element does
not become clogged, because this condition may result in a faulty machine
action.

SECTION V. ADJUSTMENTS

WHEEL SPINDLE BEARINGS ADJUSTMENT

While these bearings are adjustable, we caution against any

promiscuous tampering with them. Many machines are on record whose

bearings have not been adjusted over long periods, and it is advised that

such adjustments be made only when the need has been definitely proved.
In this case, a very slight adjustment should be made and repeated if
necessary. This is to avoid the possibility of tightening too much and

causing overheating or seizure.

In making an adjustment, set up but one bearing at a time,

allowing the machine to run under working conditions for a day or so
before adjusting the second bearing, if this is necessary. The cooler
bearing is naturally the one to adjust first. Do not attempt to adjust

bearings when they are cold. In preparing to adjust a bearing, be sure
to loosen the wedge bolts of the bearing concerned. Do this upon removal

of the spindle housing cover so that this step will not be overlooked.

NOTE: Reduction in the diameter of the bearing
bore is obtained by drawing the bearing into its
case by tightening the inner spanner nut. The
taper on the O. D. of the bearing is such that
when the bearing is drawn into its case . 012"
reduction of .001" is obtained in the bearing
bore

.

Therefore, to obtain . 001" reduction of the spindle bearing

bore, set up a clearance of .012" between the outer spanner nut and the

spindle bearing case by use of a feeler gage. Now tighten the inner

spanner nut until the outer nut is seated against the bearing case,

should give . 001" reduction of the bearing bore. Use this twelve to one

ratio to obtain any reduction desired.

When the bearing has been drawn into its case, loosen both the

inner and outer spanner nut. This move is important. The bearing will

remain at the point to which it has been drawn. Now tighten the wedge
bolts which will straighten the bearing in its case if there has been any
tendency toward twist. After the wedge bolts have been brought up snugly

(do not tighten excessively), bring up the inner and outer spanner nut

snugly but not too tightly and replace the housing cover.

This

WEDGE BOLTS AND SPANNER NUTS

The wedge bolt tightening operation is extremely important.
They should be brought up snugly but not excessively tight. The wedge
bolts straighten up the bearing in its case, and to do this effectively, the

outer and inner spanner nuts must be loose. After this is done, tighten
up the outer and inner nuts firmly, but not too tightly,
nuts will set up strains in the bearings which may lead to trouble.

Hammering on the

Do not

15

m

pound on the wrench with a hammer and under no circumstances should

a set or punch be used in adjusting these spanner nuts, since these tools
will cause a peening action which in time might cause oil leakage from
the bearing.

BEARING TEMPERATURE

Bearings should never be adjusted when they are cold. Should

the machine be in need of bearing adjustment, allow it to run for some
time until the bearings warm up. A bearing, if adjusted when cold, will
often seize the spindle when the latter is allowed to run. This seizing is
caused by the differences in expansion occurring in the spindle parts and

the fact that a cold adjustment does not usually provide clearance enough
for the expansion of the spindle.

WHEELHEAD MOUNTED AUTOMATIC TRUING DEVICE

GENERAL INFORMATION

SECTION V I

m

m

As the name implies, this device provides automatic truing of
the grinding wheel or wheels. An auxiliary manual means of controlling
the device is provided for setting up purposes. A selector switch in the
push-button station provides either automatic or manual control. With

the selector switch set at "Manual" the device is operated by two push
buttons mounted on the rear of the device.

INITIAL OPERATION

In initial or experimental operation of the Wheelhead Mounted

Truing Device, set the selector switch to "Manual" and make sure that
the diamond in the device is raised sufficiently so that it will not contact
the grinding wheel before such action is intended. Raise the diamond
with the small hand wheel on front of the device, and use the "door" in

the wheel guard to observe that proper clearances exist. With the
diamond clearly above the grinding wheel, run the device back and forth
by operating the push-buttons on the back, until the manner of operation

is understood.

INITIAL TRUING

For initial truing of the grinding wheel, continue to operate
the device manually, and bring the diamond into light contact with the
grinding wheel by hand. Feed the diamond very lightly at each reversal
of the device by use of the small hand wheel "R" as shown on page 20.



H

DETAILS OF OPERATION

In normal operation of this device, the Operator touches the

push-button labeled "Truing Start", located in the push-button station.
This energizes solenoid valve "A." Energizing this valve allows pressure
oil into the left-hand side of the truing slide hydraulic cylinder for movement

of the slide. At the same time, oil on the right-hand side of the cylinder
exhausts through speed-up valve "B" and through the needle valve mounted

on the rear of the device.

FAST TRAVERSE

When the diamond truing moves from its rest position, the

right-hand speed-up dog "C" depresses the speed-up valve plunger to allow

the exhaust oil to flow freely through speed-up valve "B". This gives the

truing slide a fast traverse from the rest position of the diamond tool to the

edge of the grinding wheel. On reaching the wheel, the speed-up dog rides

off the plunger and closes the speed-up valve "B". With this valve closed,
the exhaust must pass through the needle valve which gives the required
truing speed to the tool slide.

I

FAST REVERSAL

When the diamond reaches the opposite edge of the grinding wheel,
the left-hand speed-up dog "D" depresses the plunger which again opens
passage through speed-up valve "B" and the slide goes through fast reversal
back to the edge of the grinding wheel. The reversal is accomplished by the
truing slide actuating limit switch "E" which is mounted on a slotted bar
fastened to the top of the mechanism. This action de-energizes the
solenoid and reverses the hydraulic pressure from the left-hand to the
right-hand side of the truing slide cylinder.
of the cylinder now exhausts through the speed-up valve "B" and through
the needle valve.

AUTOMATIC DOWN-FEED

At the end of the first pass, while the slide is going through its
fast reversal, diamond picker feed ratchet "F" is actuated by ratchet crank
actuating adjustment "G". This gives diamond holder "L" the desired
amount of automatic down-feed. (See "Adjustments" on page 22).

At the end of the return pass, the diamond picker feed ratchet

"F" contacts ratchet crank actuating adjustment "H" which feeds down the
diamond. The slide then comes to rest and is set for the next truing
operation.

INDEXING

Oil on the left-hand side

'

After the truing operation, the wheel must be repositioned to
compensate for the reduced diameter. Push the wheel feed index knob
inward and use the click-count to back off the handwheel an amount equal
to the amount trued from the diameter of the grinding wheel. For example,
if the diamond feeds . 0005" per pass, the radius of the wheel is reduced . 001" ;
the diameter . 002" . The index knob, then, is turned back 20 clicks and there
is no need for further adjustment.

MAINTAINING ACCURACY

To maintain accuracy of truing, keep the rollers of the device

tight.

The dove-tail gib must be adjusted to give a snug sliding fit on the ways.

Oil the rollers and ways frequently with a high lubricity oil to
