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.

MOUNTING THE GRINDING WHEEL

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.

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.

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.

Coolant tank capacity is approximately 150 gallons.

SECTION 11 . LUBRICATION

VISCOSITY RATING

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

1

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.

1

1

v

i

i

■

■

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.

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.

■

■

■

r

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.

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.

FOOTSTOCK

The footstock usually supplied is the lever type with spring

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.

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.

i

i

■

*

*

■

f

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 . 00

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.

l" is obtained in the bearing

This

f

r

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. ?\.fter 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.

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. Hammering on the

nuts will set up strains in the bearings which may lead to trouble. Do not

15

1

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.

SECTION V I

WHEELHEAD MOUNTED AUTOMATIC TRUING DEVICE

GENERAL INFORMATION

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.

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

INITIAL OPERATION

With



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*

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.

■

1

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.

FAST REVERSAL

When the diamond reaches the opposite edge of the grinding wheel,
the left-hand speed-up dog ,,Dn depresses the plunger which again opens
passage through speed-up valve nBn 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

fast reversal, diamond picker feed ratchet "F" is actuated by ratchet crank
actuating adjustment "G". This gives diamond holder "L
