UNCRATING, ERECTING AND STARTING MACHINE

Unpacking the Machine

Care should be exercised in removing the box or crate from the

machine. Boards should be removed piecemeal from the container. Shocking
the machine by heavy blows on the container, must be avoided. While the
machine is sturdily constructed, there are parts which are liable to damage

if given rough treatment.

Inspection

Inspect the machine thoroughly after the container has been removed,
to be sure that no damage has occurred during transit. Check the entire
shipment against the shipping list. See that small parts are not thrown away
in the packing materials. Small parts, especially wrenches and gages, should

be given to the foreman in charge of the job.

Wheel Guard Adjustment

The wheel guard, which can be mounted on either end of the spindle,

should be adjusted so that it clears the wheel by about 1/16" at the front and

then clamped in position by means of two hex head screws on the wheel slide
bracket. Turn the wheel at least one revolution by hand before applying the

power to make sure that it will clear the guard. The wheel guard is easily
opened for wheel change by loosening the knurled knobs on the top and back.

Headstock and Footstock

Wipe the headstock and footstock off, being careful that no grit
becomes lodged between their bearing surfaces and the table. The spindles
of both should be thoroughly wiped out and the centers carefully inspected.
The centers must seat perfectly in the spindles if good grinding results are
to be obtained.

On the headstock, be careful that the plunger and the dog drive
plate and spindle cam lock are not engaged at the same time. The spindle
cam lock is controlled by a handy lever extending out both sides of the body.

side of base, by removing a single cover.

Coolant

Check the clean-out door on the left-hand side of base to be

sure it is securely latched before pouring the coolant into the reservoir.
The grinding compound or soluble oil used in making the grinding coolant
should be prepared, the proportions being two or three pounds of compound
or 50-60 to one by volume of soluble oil to a tank full of clean water. The

coolant tank has a capacity of 30 gallons.

Practical Experimenting

If operation of a Universal Grinding Machine is entirely new to
the operator, we advise that a little time be spent in studying the general
functions of the various control levers. Care must be exercised while
doing this practical experimenting so that no damage will be inflicted.

Do this experimenting with no work between the centers, with the wheel
slide in its maximum rear position, the wheel stopped and with the table

dogs set about 6" each side of the reverse lever.

CONSTRUCTION

TABLES

The 10" Universal Grinder has two tables known as the sliding
table and the swivel table
of the base and supports the swivel table. A tapered pivot joins the two tables
at the center and is the point about which the swivel table is moved when
adjusting, to grind the work straight or to produce some definite taper.

Clamping

There are two clamping levers on back of the headstock which
are used for clamping the headstock to the table. With the clamps
loosened, the headstock may be pushed to any position on the table.

Speed Control

Lubrication

6.

The six sturdy bearings on the spindle are thoroughly greased
at the factory and will need no further attention for a long period of time.
However, when the time comes to further lubricate these bearings it will
be found to be an easy matter to do so by removing the dog-drive

plate

and spanner nut behind it.

Plug-in Receptacle

The headstock may be used at the left or right-hand end of the
table with equal ease and efficiency and with either end of the spindle
toward the footstock. This feature is facilitated by having a plug-in
receptacle at each end of the base.

FOOTSTOCK

The spring tension and limit stop are typical of standard

The amount of tension on the center may be adjusted

by a knurled knob on the rear of the footstock body.

The rack and pinion principal of retracting the center is

accomplished by having a pinion segment, attached to a pivoted lever,

meshing with a rack cut on the underside

of

the footstock spindle. The

spindle may be locked in any desired position by tightening down the

knurled knob on top of the footstock body. The clamping of the footstock
to the table is the same as for the headstock with the use of a wear strip
against the alignment surface and a clamp on the opposite side. The
diamond tool holder may also be easily transposed for right and left hand
operation.

The external wheel drive motor base is attached to the top of the
wheel head by a single bolt. When reversing the wheel to the right-hand
end of the spindle, the motor is reversed by loosening this bolt and
reversing the base. The wheel guard unit, spindle belt guard and coolant

pipe arrangement may be clamped on either side with equal efficiency.

The wheel head casting is a sliding member and may be moved forward
or backward on the wheel head swivel casting below it, thereby giving
additional capacity. This is done by loosening three tee bolts, two on

the top forward section, and one in the rear.

Hydraulic Oil

For the hydraulic system of this machine, a combination
oil for hydraulic use and having oily additives for ways lubrication is
suggested. This oil should have a viscosity of 275-375 S.TJ. V. at 100°F.

Ways Lubricant Flow Control

For control of ways lubricant flow, two needle valves are
installed in the machine in the portion of the base cavity immediately
beneath the wheel slide. These are reached by removing a cover that
will be found in the base wall beneath the wheel spindle belt guard.

These valves are placed with relation to the table way served.
The forward valve controls lubricant flow to the forward table way, and
the rear valve controls lubricant flow to the rear table way.

If adjustment of ways lubricant flow becomes necessary,

establish the proper valve setting by proceeding with caution.

OPERATION

It will pay the operator to study the 10
Grinder and to this end a description of the various functions and adjustments
of the units is given. It is suggested that settings and adjustments be tried

in order that he may be perfectly familiar with the tool and job grinding
possibilities of the machine.

Double Swivel Wheel Head

n x 20" Universal

*

■

■

■

The double swivel arrangement of the wheel slide is

extremely useful. The wheel head unit can be swiveled in two places, at
the wheel head swivel and the compound swivel. Since the traversing of
the slide is accomplished by a set of bevel gears with one free to be
swiveled about the other, the wheel may be fed in at any direction by the
wheel feed hand wheel. In other words, depending upon the setting given

to each slide, the wheel may be set at any angle to the table and fed at

this angle, or it can be set at any angle and fed perpendicularly to the
table ways. Swiveling the compound swivel permits feeding the wheel
at any angle; swiveling the wheel head swivel permits the wheel to be set
at any angle regardless of feed.

It should be remembered that when feeding at any angle the

index values mentioned before are the amount the wheel slide moves in
the direction for which it is set
at 45° and a diameter and shoulder are being ground, with the wheel feed
index set to advance the wheel . 001", the wheel would actually advance
. 001" at the set angle but only comes into the work diameter . 0007",

reducing the diameter . 0014" and the shoulder dimension by . 0007".
Since this versatility is so extremely useful, the operator is urged to
study the unique construction of the slide and make practical tests of the

unit to discover its possibilities.

. For example, if the slide is set to feed

Combination Angles

By setting the wheel slide at some angle and the headstock
at an angle which added to the previous angle is equal to 90°, it is possible
to obtain additional capacity between the wheel face and the face of the jaw
chuck or face plate. This is extremely useful in face grinding operations

because with the headstock swung around 90° it is not possible to clear the
chuck jaws with the grinding wheel. By setting the headstock at 45°,

rotating the Compound Swivel 45° counterclockwise (if viewed from above)
and swiveling the wheel head 45° clockwise (90° in relation to the compound
swivel) ample capacity for any face-grinding operation which should be

done with this machine is obtained.

Center Rest

may be pointed out that the shoes on the arms should be adjusted with

considerable care to prevent either a binding action or excess play of the
workpiece. That the work should be centered is fairly obvious and it is
considered good practice that the piece, once located in the rest, be
checked with a dial indicator before actual grinding is started.

The internal grinding attachment is hinged forward and
clamped to the dovetail on the front of the wheel head. Swiveling the
wheel slide affects the internal spindle in the same relation as it does

the regular wheel spindle. The internal spindle drive is by flat belt.

This belt drops down into position as the attachment is lowered for
grinding. In the event that the work does not come straight, the error
can usually be traced to one of two things - (1) the headstock is not set
exactly at zero, or (2) the swivel table is not set correctly for grinding
straight work. A small error at either of these settings would naturally

produce a tapered hole.

Wheel Contact

Ordinarily the internal spindle wheel is brought against the

front inner surface of the work, since in this way the operator is able to
use the stop on the wheel feed index for gaging the size of the work.
However, if the operator prefers to grind on the back inner surface, he
may feed the wheel micromatically with the index, but he will have no
stop to guide him. The use of the wheel on the front or back surface

Hydraulic Operation

There are two important functions of the hydraulic system
in this Universal machine. The first is the traversing of the table, while
the second is the so-called "picker feed" of the wheel slide which operates,
if the operator so desires, at each reversal of the sliding table.

Testing Pressure

Pressure in the system may be determined by first shutting

hydraulic

pump. After the plug is removed a pressure gage may be screwed

into place and the hydraulic pump started. The table should be run back and

forth several times, then turn the table speed dial to zero while leaving the
table start-stop lever in the start position. Now a true pressure reading
can be taken.

d. Adjust the pick-up screws to set the needle of each meter to

clockwise (as viewed by the operator when standing in front of the
machine) the needles should be moved to the left of zero and

vice-versa.

e. The swivel table adjustment may now be used to swivel the table until

both needles have moved to the zero position on the meter scale.

If movement of the table is sluggish the needle recording

motion at the headstock end of the table may fail to move or follow
the other needle. This means that the table is being deflected and a
slight rap or jar on the table will usually break the oil seal and

permit both ends of the table to move the same amount. When both
needles are at the zero mark the table is straight, the work centers

are in alignment and the error has been corrected.

Since corrections made are based on adjustment of the pick-up
screws at the ends of the table and the needles register taper per foot, not

location of the workpiece relative to the pivot point of the swivel table.

GRINDING PRINCIPLES AND GENERAi, PROCEDURE

Factors Governing Finish

20.

SECTION IV

Two major factors may be said to govern the quality of
finish on a ground surface. The first is the manner in which the machine
operates, and the second is the condition of the wheel face. The former
is a matter of mechanical perfection and NORTON machines are second

to none in freedom from vibration

The condition of the v/heel face depends on proper wheel selection and is

f

21.

■

Finish Truing

Truing for finer finishes from this point consists of

reducing the table traverse to the slowest speed comparable to the
finish desired, and reducing at the same time the amount of the feed
of the wheel toward the diamond. In fact, for the finest of finishes
it is advisable to make several passes of the diamond across the

wheel without any inward feed of the wheel.

Truing Summary

In summation, it may be said that good truing technique
is obtained only through experience. Rough truing consists of opening
up the grinding surface of the wheel to expose sharp abrasive surfaces
necessary for the rapid removal of stock. Finish truing, requiring a
smoother abrasive face, requires the lightest possible feeds of the

wheel to the diamond and the slowest possible table traverse compatible
with the production and finish desired.

Truing Precautions

Care should be taken in any truing operation but

especially when a diamond truing device is being used. Avoid continual
truing. A wheel which requires constant truing is incorrect for the job
and should be replaced. Avoid excessive wear of the diamond on wheels
which are too hard. Avoid also the practice of cutting with the diamond
before the coolant is turned on, because, with the diamond heated up,

the coolant might crack the stone or loosen it in its nib. Be sure to
have at all times a sufficient flow of coolant at the point of contact

between the diamond and the wheel. Always bring the diamond onto
the wheel in the approximate center of the grinding surface since this
avoids the possibility of the wheel first striking the side of the nib and
causing undue strain.

The number of rests to be used depends entirely on the

work to be done. Naturally, a long slender piece of work will have a

greater tendency to spring than a short stubby bar. No set rule can be
given for the number of rests to be used on work in general,
depth of the grind and the quality of finish are important factors to be
considered.

SETTING-UP ROUTINE

Work Location

The first thing to do is to set the headstock and footstock
for the length of the piece to be ground. These can be set anywhere on
the table but it is better practice to have the center of the workpiece
come approximately

in the index setting and finally reduce the piece to size.

Wheel Wear

wheel wear, the piece will be somewhat oversize. Wheel wear, of course,
