shaped media, porce-
lain is also used to
accomplish the same
task. The big differencebetween these two
compositions is, once
again, the weight fac-
tor. In fact, that is the
main popularity of steel
media - it is heavy,
about 300 lbs per cubic
foot versus about 100
lbs for porcelain and
most other ceramic
abrasives. Steel worksrelatively fast to pro-
duce a bright, shiny
surface appearance;
however, shine does
not necessarily trans-
late into smoothness.
In addition to steel and

I have not mentioned
anything about bur-
nishing media up to
now. That is because,
other than size and
shape, there are no
major differences or
variations for this type
of media; but size still
determines weight, and
that is a factor for se-lection. Non-abrasive
shapes work parts the
same way that abra-
sives do, but because
there are no abrasives,
there is little to no ma-
terial removal. Any ma-
terial removed is due
to metal fatigue
caused by flexing. An
exception to this is asharp, spiral cut cylin-
der that is only made
by one company, and
is designed to actually
remove material as
long as the spiral ribs
are still intact. Fine,
inorganic materials can
be added to steel for
deburring, but it is not
recommended becauseof cost factors, and
because all steel media
is heat treated to cre-
ate a case hardening
that is very thin. Be-

worked. One of the more com-
mon suggestions is to select a
shape that is larger than the
holes in the part. If you have togo smaller, try not to select a
media that will get stuck in the
hole or is close to the hole di-
ameters when you double or tri-
ple up the media in a bunch.
Round or diameter media seems
to get stuck more than the geo-
metric shapes. Before selecting
a media, get a couple of sample
pieces, bunch them up, and just
trying to force them into possi-ble problem areas of the part or
parts is one of the best ways to
check out this lodging problem.
Why lodging occurs at all is an
interesting story; however, the
main reason is that the shape of
or crush, and the other to
scrape. The shape, in mass, also
affects the way the parts move
within the equipment. That is,rounded shapes tend to move
more and allow parts to seek
greater depths than straight
edge shapes. Geometric shapes
tend to have a build up of resis-
tance and force that removes
material, while somewhat sup-
porting parts higher up in the
work mass. Both shapes work
(provided the media can get into
the work areas), but for smooth-ness I suggest rounded shapes,
and for a lot of material removal
I suggest geometric shapes.
One of the biggest problems
with either shape is the media
getting stuck in the part to be
porcelain, aluminum shaped ma-
terials, brass, zinc, and other
metals are available in cut wire
products and balls.Before we talk about the subject
of organic materials, I want to
mention a few things about the
physical shape of media, be-
cause shapes are a factor in the
processing of parts. Most shapes
can fall into two categories; I
have classified them as either
bulldozers or steamrollers.
Maybe rollers or scrapers would
be better terminology. In either
case, you have shapes that have
a lot of diameter, or straight
edge exposed in contact with
the parts being worked. That
means that the main function of
the media shapes is either to roll

the media is such that the cen-
ter of gravity is usually right in
the physical center of the shape.
That means that the actual
movement of the media is very
stable and tends not to want to
move at all, which is contrary tothe purpose of mass finishing.
That stability factor is usually
overcome by the energy forces
or action of the equipment,
which sets this media into mo-
tion. However, if the media
should find itself restricted, it
usually just rattles around to a
very small degree until it cant
move any more.
Now, with all of this information
about media shapes, there is
one exception to all of the
above. There is one shape,
called either the V shaped cylin-
der, cylinder wedge, or tri-
cylinder that looks and is made
differently from almost all the
other shapes. It is interesting
because of its unusual appear-
ance and behavior characteris-tics. This shape looks like a
piece of pie or triangle in one
direction and a cylinder in the
other direction and it has its
center of gravity on the outside
edge. This latter statement
means that the media shape is
very unstable and very mobile.
It exhibits the characteristics of
both a roller ( it has an overall
round shape) and a scraper( two flats forming a very sharp
wedge); therefore, it is usually
the best general purpose shaped
media available for all applica-
tions.
Up to now, all of the media that
we have discussed is run in what
is called wet processes. That is,
these shapes are run with water
and some chemical compound.
All mass finishing systems are
built with drain systems and pro-
visions for liquid input. Because
parts are made with cutting oils
and pick up oils, greases, anddirt either by design for protec-
tion or by accident, chemicals
are normally necessary to aid in
the processing of the parts.
Common practice is to use a wa-
ter based biodegradable product
in a diluted strength which can
either be premixed or propor-
tioned into the system. The pH
of the product is important, but
not the only factor. Inhibitors for
protection and wetting agents
are also desirable. The pH of
waters is listed as 6.7 pH. Any
number above water is consid-
ered basic, or caustic after 11,
or acidic under the pH of wa-
ter. Most chemical additives are
interchangeable with either fer-
rous or non-ferrous parts, but
most people use basic chemicals
for ferrous parts and acidic prod-
ucts for non-ferrous and bur-
nishing.
At one time chemical com-
pounds that produced a lot of
suds were considered desirable
for cleaning of the parts. How-
ever, it was determined that the
suds actually slowed down the
mechanical action of media in
mass, causing longer time cy-cles. This same slow down of
the media in mass can also be
accomplished by just using too
much water in the process, but
it can also be accomplished by
accident when drains become
clogged or restricted due to de-
bris. Even though chemicals are
used to assist cleaning and
brightening metals, which is a
removal process, an inhibitor in
the product is usually desirable
to protect parts against oxida-
tion. Lastly, there are now some
stronger chemical additivescalled accelerators that are used
to help speed up the deburring
process. Because the chemical
does most of the work instead of
the media, it is usually recom-
mended the media contain no
abrasive; thereby, there is cost
savings of the media which does
not have the same wear rates as
abrasives.
Dry organic media is the last
category of media used in mass
finishing systems and, as the
name implies, this media is run
dry. Anything that can be proc-
essed wet can be done with dry
organic materials. The only
problem is the longer cycle time
due to the weight factor. The
main advantage over wet proc-
essing of this media is in the de-burring or polishing of small or
flat parts. Both types of parts
mentioned have a tendency to
stick together due to water ad-
hesion, and they also adhere to
the sides of the equipment being
used. This characteristic causes
uneven surface finishing. The
other advantage of dry process-
ing is the elimination of water
pollution controls or restrictions;but there is a trade off. Instead
of water and waste disposal
problems, there is some concern
for dust particles that need ei-
ther a cover or proper air venti-
lation.
Dry organic media comes in the

What is dummying tanks? How is it done? What
happens to the anodes while dummying is going
on? I will need to answer my students questions
in the near future.
Dustin Gebhardt
Dummying is the common term for dummy plat-
ing, or using a scrap piece to plate, usually at
lower or higher then normal current densities.
If you were constantly nickel plating zinc, or cop-
per, or brass parts, you would frequently dummy
plate the bath at low current densities to PREF-
ERENTIALLY remove the copper and zinc. Nor-mally, the dummy has a large surface area, to
maximize the amount of material removed. In
my experience, a large piece of corrugated sheet
metal is used with a current density close to
5ASF or lower.
There are other uses for dummy plating. In a
hex chrome bath, it can be used to remove chlo-
rides and activate the anodes. These dummies
are usually very small to prevent the buildup of
tri chrome. You can also perform a high-current
density dummy plate to remove excess bright-
ener.
A separate dummy tank is usually one that is
used to perform the dummying in. You can also
do a continuous dummy, where you use a small
tank with a separate rectifier, anodes, and
dummy panel to perform the dummying continu-
ously. Usually, you pump the solution into the
tank, which is higher in elevation than the main
tank. As the dummy tank fills, it overflows back
into the main tank. Many platers use them in
high-production shops to minimize down time.
One thing to consider with the current price of
nickel. While dummy plating targets a certain
contaminant (usually), you are still plating a ma-
jority of your normal metal. That is to mean, in
a nickel bath, you can try to dummy out zinc,
but the majority of the deposit on the dummypanels will still be nickel. The zinc content will
be higher than on a normal deposit, but it will
still be mostly
nickel.

Hello Harold,
As far as I know
you can use almost
any kind of com-
patible material to
perform this dummy
plating. You can
see in the pictures
that these Dummy
Plates have been
fabricated so as to maximize the surface area.

Those type of panels tend to work very
well. They can also be rotate 90 degrees to help
remove shelf roughness in a pinch. The smaller
you make the "shelves" the more uniform the
surface area will be, and generally the more ef-
fective the panels will be. This will allow you to
HCD dummy the bath without affecting the LCD
chemicals, and vice versa. With panels that
have larger folds, you tend to build up a lot of
plating on the corners and very little in the con-
cave areas, making the panels less efficient.

form of small random shaped
particles of granules or sawdust
fiber, which can either be used
by itself, or in a two part form.
The finer material is normally
used with larger wood shapes in
a 5:1 mix of shapes to particles.
The reason for this two part mix
is that there is hardly any weight
to the organic materials. They
weigh only between 20 to 35
pounds per cubic foot; there-
fore, bulk or the wood shapes
are desirable for adding weight
to the process to improve cycle
times. Other, non-abrasive heav-
ier media can be added for bulk
and produce good results.
When any dry organic materials
are combined or mixed with pol-
ishing rouge, they are excellent
in producing almost hand buffed
looking, polished parts. When
combined with inorganic materi-
als, they are very effective as
abrasives. Because of the weightfactor, the deburring and polish-
ing qualities of these blended
mixes still take a longer time to
produce the same results as wet
process media, but usually the
surface finish is of superior, finer
and cleaner quality.
Within the last 5 years, a new
form of dry organic materials
has been developed that looks
something like plastic media.
There is now a patented com-
posite process that takes inor-
ganic and dry organic materials
and makes them into shapes,
which are used in dry process-
ing. These shapes are made in
such a way that they can actu-
ally have more inorganic abra-
sives than the dry organic mate-
rial, but they are still used dry.
Also because of the increased
weight of this preform, it is now
competitive to wet processing
media in time cycles and without
the problems associated with
water. According to the manu-
facturer, this new material will
outlast all other abrasive media
by 5 to 20%. The advantages
offered by this dry media and
applications normally warrant
the extra high cost of this new
product.
As you can tell, there are three
main factors that control de-
burring or burnish of parts in a
mass finishing system, they are:
the equipment, the media, and
either the liquid or additive to
the operation. Surface finishing
on parts can be repeated over
and over again if these elements
are constant. Any variation ofone of these elements will
change the results or time cycle.
Basically, once a machine sys-
tem is selected you are locked
into some limitations of that ma-
chine system. Therefore, that
means that media selection is
probably the most important
variable in the processing of
parts, and effects the costs of
operation and the surface finishthe most. Hopefully, with some
of these basic fundamentals
down, you can better achieve
the processing results you are
looking for. If you do, however,
need help or further information,
you can contact A.F. Kenton at
Nova Finishing Systems Inc. or

The widely discussed and an-ticipated Sur/Fin 2008 confer-ence and tradeshow culminated
on June 18th, after three days of
industry discussion, education,
exhibition, and camaraderie.The conference, put on by the
National Association for SurfaceFinishing (NASF), showcased
more than 150 exhibitors and
attracted more than a thousand
finishers and general attendees.
Special events this year includedthe NASFs Indianapolis Branch

few blocks away from the Indi-
anapolis Convention Center. Anunanticipated number of people
turned up for food and fun butthe more, the merrier! Finishing

its dazzling array of antique race carsand motorcycles, speedway memora-
bilia, and more, to the delight of all in
attendance. There was a delicious ca-

by small bus tours of the Speedwayitself, giving riders the opportunity to
get off and take photos at the finish
line (which is composed of bricks fromthe original track surface!).
Educational opportunities consisted ofa wide array of symposiums and train-
ing courses. Featured sessions werethose that were covered during the
Automotive Symposium, Airline/
Aerospace Symposium, and the Sur-
face Finishing Research technical con-ference. Within these broader fields
were classes, lectures, and workshops

and more. This years featuredspeaker, Dr. Robert Schnorbus
of J.D. Power, gave those inattendance an in-depth look
into the impact of global sourc-ing, supplier concerns, and
other related regional and
global issues affecting theautomotive industry.
The NASF member pavilion
was a popular spot for casual
socializing, catching up withphone calls or e-mail, taking aquick break from all the walk-

people attempting to catch upon their sleep after a night out
in Indy - in addition to a con-

E ffective July 7, 2008, the Environmental Protection Agency (EPA) will amend the list of hazardous wastesfrom non-specific sources (called F-wastes) by modifyingthe scope of the EPA Hazardous Waste No. F019. Specifi-cally, the agency plans to exempt wastewater treatmentsludges from zinc phosphating, when such phosphating isused in the motor vehicle manufacturing processprovided that the wastes are not placed outside on theland prior to shipment to a landfill for disposal, and thewastes are placed in landfill units that are subject to ormeet the specified landfill design criteria.
Note: This final action on the F019 listing does not affectany other wastewater treatment sludges either from thechemical conversion coating of aluminum or from otherindustrial sources. Additionally, this rule amends the Com-prehensive Environmental Response, Compensation, and
Liability Act (CERCLA) list of Hazardous Substances andReportable Quantities so that the F019 listing descriptionis consistent with the amendment to F019 under regula-tions for hazardous wastes from non-specific sources.
This final rule could directly affect businesses that gener-ate certain wastes from the manufacturing of motor vehi-cles in the (1) automobile manufacturing industry and (2)light truck/utility vehicle manufacturing industry (NAICS
codes 336111 and 336112, respectively). Other motorvehicle manufacturing industries (e.g., heavy-duty truckor motor home manufacturing) are not affected by thisrule.
Entities potentially affected by this action are at leastseven current F019 generators within these two indus-tries, consisting of four auto and three light truck/utilityvehicle plants, and up to 42 other facilities in these twoindustries that may begin applying aluminum parts andcould potentially generate regulated F019 waste withoutthis final rule (based on 2005 Biennial Report data).Note: This action might also affect the 19 auto and lighttruck plants with prior F019 delistings issued between1997 and 2007, because this action could supplant theirdelisting status and conditions, depending upon the ex-tent of state government voluntary adoption of this final
rule [1].
The EPA has established a docket for this action underDocket ID No. EPA-HQ-RCRA-2006-0984. All documentsin the docket are listed at the www.regulations.gov web-site. For information on specific aspects of the rule, con-tact James Michael of the Office of Solid Waste (5304P),U.S. Environmental Protection Agency, 1200 Pennsylvania Avenue, NW, Washington, DC 20460, via e-mail [email protected], or by phone at (703) 308-8610.

Products Finishingmagazine recently unveiled theproduct of its collaboration with the popular metalfinishing community and forum, Finishing Talk. Over
the past two years, Finishing Talk has exploded ontothe industry scene as a cutting edge online commu-nity, forum, newsletter, and marketing company formetal finishing professionals. With a rapidly growingmembership and an active community forum, Finish-ing Talk was an appealing choice for a cooperativeweb endeavor with Products Finishing.
"The people that use PFOnline will now have anotherresource that harnesses the power of the Internet,"says Products Finishing Publisher Don Kline. "Theycan now get their questions answered by an active
community that includes top finishing professionalsfrom all over the world. PF is excited to be workingwith Finishing Talk."
Products Finishingmagazine is an industry renownedpublication with more than 40,000 subscribers - thelargest circulation in the finishing industry. Themagazine's Web site, www.pfonline.com, is an estab-lished and respected resource for metal finishers. Itcontains a large database of industry suppliers andproducts, extensive archives of past issues, an inter-
active clinic touting prominent consultants and edu-cators, and more. The addition of the Finishing TalkForums to the site will be an added benefit, possiblydrawing a new generation of finishers into the Web
site.
The collaboration will be a big boost for the up andcoming Finishing Talk community, as well. ThoughFinishing Talk will remain an independent Web siteafter the integration, the forums will also be accessi-ble through Products Finishing'ssite. This will serveto increase traffic on the forums and bring addedexposure to other products and services that Finish-ing Talk currently offers.
"We are pleased to have this opportunity to expandour membership and provide a place for finishers to
discuss issues of importance to them, within a like-minded community. With a new gateway to the fo-rums, via PF online, more of these individuals willbenefit from this great service - and it's free!" com-mented Paul Fisher, Administrator of Finishing-Talk.com, and publisher of the Finishing Talknews-letter (yep, thats us!).

In the finishing industry, sol-vents are primarily used for partscleaning. Many of these, such as
trichloroethalene (TCE), can beadvantageous in that they are fastacting and quick to evaporate,which minimizes drying time. Onthe downside, these same solventscan be extremely toxic, carryingthe health risks of liver and kidneydamage, neurological disorders,and even cancer. They are alsoculprits when it comes to soil andwater contamination, and otherareas of environmental degrada-tion. So what is a finisher to do?The good news is that an increas-ing number of alternatives to tra-ditional solvents are appearingacross the spectrum, making iteasier to safeguard your workershealth and the health of your com-munity.
Where do I begin?
The mounting government crackdown on non-reusable or non-recyclable solvents is a good
enough reason in and of itself tostart rethinking and minimizing theuse of solvents in your operation.But where to start? The easiestfirst step is the first step of any
sustainable approach; that beingto reduce wherever possible. Ifyou can use less of any hazardoussubstance, then make sure to doso.
Once youve filtered out what canbe reduced, its time to focus on
what can be replaced. It is impor-tant to first go through and iden-tify the uses and volumes of sol-vents you have in your facility,which will allow you to determinewhich ones should and can besubstituted with something else.Examine your current stock of sol-vents, keeping an eye out forthose containing chemicals or
and to remove grease and oil,whereas the CO2 Snow relies onflakes of frozen CO2 to clean sur-faces. Another cleaning alternative
is Supercritical Fluids. Lacking insurface tension, these fluids canquickly and thoroughly dissolvecontaminants, and are easy toremove. Yet another option is Me-dia Blasting, which is a processthat uses abrasive media (such assand, glass beads, and more re-cently plastic particles) dispersedat high pressure against a surfaceto remove contaminants.
A great resource for finding com-
parable solvent replacementsis the Toxics Use ReductionInstitutes (TURI) Surface Solu-tions Laboratory,(www.cleanersolutions.org). Hereyou will find the easy to navigate
Replace a Solvent page, allowingyou to search for alternativesbased on the solvent you wish toinvestigate, and then narrowingdown your results by contaminant,substrate, and even equipment
type. TURI is an especially helpfulresource, due in large part to thefact that they actually test thesealternatives, and rate them ac-cording to their effectiveness inapplication. Another good re-source is the Integrated SolventSubstitution Data System (ISSDS)at http://es.epa.gov/issds.
Always consider the potential envi-ronmental impacts, health andsafety concerns, solvency, flam-
mability, cost, and stability of asolvent before choosing the rightone(s) for your needs. Since thereis no single miracle solvent outthere, be sure to evaluate eachoption thoroughly in order toachieve the best results, whilecausing the least negative impactto your workers, your community,and your environment.
compounds that may soon bephased out. You should ask your-self the following questions:
1. What are the parts that need
to be cleaned?
2. What contaminants are being
removed during the cleaning proc-ess?
3. Why are these parts being
cleaned? (In some instances, itmay turn out to be an unneces-sary step and expenditure)
4. How can I stop contamination
at its source, prior to the need for
cleaning?5. To what degree must theparts be cleaned?
After you have answered thesequestions, you can apply thisknowledge to your quest to findthe most functional and effectivealternatives.
Alternatives to ConsiderThere are several popular andcleaner alternatives to solvent
cleaners available to finishers to-day. One of the most popular iswater-based cleaning, also knownas Aqueous cleaning. Variousprocesses to remove contaminantsinclude the use of acidic and/oralkaline aqueous solutions, as wellas immersion, pressure spray andultrasonics. A compromise be-tween solvent use and aqueouscleaners is what is known as aSemi-Aqueous cleaner: a semi-
stable mixture of water and sol-vents (or emulsions). These areoften used for removing waxes,heavy greases, tar and baked-onorganic materials.
Carbon Dioxide (CO2) Blasting isanother option that consists of twomain technologies: CO2 Pellets andCO2 Snow. The Pellets combinesolid CO2 and a gas to strip paints
