1.0 First Steps
1.1 Inspection
Upon receipt of the CPC1500, perform a thorough inspection of the shipment. Compare what you
received to the packing list to be sure you have all the components, including any supplies you may
have ordered. Check for any damage to the equipment. If damage is found, notify the delivering freight
company and United Surface Solutions LLC immediately.
1.2 Selecting Equipment Location
Placement of the new equipment should be decided before the delivery date. The equipment locations
should be based on the “flow of parts” in your factory. The CPC1500 requires electrical power and
optional water source to operate, although for most applications, fresh water, a wastewater treatment
system, a drain, and a large work surface should be provided near the machine. United carries a full line
of workstations and wastewater treatment systems and is happy to recommend appropriate equipment
to fit your needs.
It is recommended to leave at least three (3) feet on each side of the machine for maintenance purposes.
Sufficient work and storage space is also required.
1.3 Equipment Setup
Isolation Pads
While setting up the CPC1500, make certain that High-Capacity Rubber Isolation Pads (rated at a min.
of 1500 psi) are installed under each leg of the unit. These pads are used to level the equipment and
will extend the service life of the machine. The leveling procedures will be explained later in this section.
Electrical
A licensed electrician is required to connect electrical power to the CPC1500. The power requirements
are printed on the data plate, located on the machine’s rear panel.
Caution: Be sure to connect only the specified voltage to the machine! These systems are built with standard voltage of
230VAC. They can be ordered in 208, 380, 400, 460, and 480 volt configurations. Applying excessive voltage will result in
severe damage to your system and will void the warranty. If you question the voltage specified on the data plate, inspect
the motor and AC drive to confirm their rated voltage or call United Surface Solutions with the serial number.
A visible-blade safety disconnect is required (supplied by the customer) to connect the appropriate
power to the CPC. Connect incoming power from the safety disconnect to the junction block located in
the electrical control box. Do not connect power to any other location. A conduit is supplied on the
lower left side of the rear panel for routing power from the safety disconnect. Use an appropriate
junction box to connect to this conduit. Do not connect conduits, cables, or any other device to the
removable panels on the CPC, as this will interfere with maintenance. Be advised that the CPC will sway
(front to back) under normal operating conditions and may damage rigid conduit or plumbing attached
to the machine.

United Surface Solutions | 11901 Burke St, Santa Fe Springs, CA 90670 | [email protected] | [phone] Page | 5
United personnel are not authorized to make connections to
your building’s electrical system. Likewise, non-United
personnel are not authorized to make any modifications or
adjustments to the equipment without written authorization.
Doing so may compromise operator safety as well as your
warranty.
Leveling
Once the electrical connections have been made, it will be
necessary to level the unit. Do not skip this step of the setup
process. This unit uses a fluid mass of media to finish your
parts and if the machine is not level, this fluid mass will favor
one side of the barrel, effectively reducing the available
working volume of the barrel. This may result in an increase in part-on-part damage. The following
instructions will aid you in leveling the CPC:
1. Install High-Capacity Rubber Isolation Pads (rated at 1500 psi) under each leg of the unit.
Recommended pad size is 6” X 6” X ½”.
2. Turn on the power for the CPC at the Disconnect Switch located inside the rear panel of the
machine. The door safety switch should release once the System Initialization is complete.
3. Select Manual Operation from the CPC Touch Screen Interface. Using the Jog controls position
the cradles to gain access to the center axle of the turret.
4. Place a Magnetic Beam Level on the center axle of the turret.
5. If adjustment is needed, shim under the Isolation Pad with varying thicknesses of sheet metal. If
large adjustments are necessary use thicker padding, standard sizing is ¾” and 1”.
DO NOT BOLT DOWN THE SYSTEM. The CPC1500 uses a rotating turret that puts stress on the
machine. Being on isolation pads, the machine is meant to “flex” and absorb this stress. If the machine
is bolted down and not able to flex, additional stress is placed on the bearings, causing premature
bearing failure. The warranty applies only when the CPC1500 is on the isolation pads. If the CPC is
bolted to the floor, the warranty on bearings, barrels, and belts is voided.
WARNING: Whenever maintenance or service is being performed on the machine, a lock must be
installed at the power supply to ensure that power is not applied to the unit.

3.5 Operating Tips
Here are a few tips for working with your CPC1500 that will make production easier and more consistent:
¬Always use a compound in wet processes unless otherwise specified. Otherwise, media will soon
take on a “glazed” appearance and will no longer cut properly.
¬Rinse parts after each step of the process. Do not let compound dry on parts.
¬Do not let parts sit for an extended period after finishing. Some materials, especially aluminum and
zinc alloys, will corrode if left in the machine for as little as 10 minutes after the end of a process.
Operate the CPC for a few extra minutes if the parts have sat in the barrel. This may help eliminate
spotting that could have developed.
¬Never put compound directly on work pieces. Always load media, parts, and water before adding
compound or you may find a residue of compound on your parts.
¬Thoroughly clean out empty barrels between process steps.
¬Never use the same scoop for more than one compound. Doing so will contaminate both products
and may result in inferior finishing.
¬Keep finishing media as clean and uncontaminated as possible.
¬Avoid inadvertently mixing media together.
¬If the work pieces are subject to rust, a rustproof treatment must be used after processing.

4.0 Process Development
4.1 Process Types
Fluent Mass: The fluent mass is employed within the barrel to provide an impinging force upon the
parts during rotation of the barrel. The types of fluent mass are often referred to as “Media”. The
parameters that define the preferred fluent mass are determined by the type of process to be
performed.
4.1.1 Cut
The cut process is used for removal of material from the surface of the parts, usually to remove milled
or coarse sanding marks. Ideally, a cut process produces a surface texture of between 32 and 10 micro-
inches. In a cut process, the individual particulate of media ranges from 0.0625” to 1.25”. The size of the
particulate as well as the media make-up or “bond” will greatly influence the aggression of the process
and the outcome of the surface texture of the part. In conjunction with the bond of the media, the
density of the media affects the aggression of the process. This is because the centrifugal barrel finishing
system is capable of generating 10 to 30 times the force of the individual media particulate. The higher
the density of the media particulate, the greater the impacting force applied to the part.
In setting the parameters which define the size of the fluent mass for the rough cut process keep in
mind the following rules: If the fluent mass particulate is too large, too much energy is imparted to the
fluent mass so that the parts are damaged when the media impinges the surface. This causes a rough
surface texture and a high peak to valley surface reading. Alternatively, if the particulate size is too small,
insufficient energy is imparted to the fluent mass. An inability to impart sufficient energy to the fluent
mass prevents the media from effectively removing a significant amount of material, thereby rendering
the process ineffective. The density of the fluent mass for the rough cut process may range from 10 to
300 lbs/ft3, wherein the optimal range is from 85 to 150 lbs/ft3, and the preferred density of the fluent
mass for the rough cut process is approximately 95 lbs/ft3.
4.1.2 Refinement
The refinement process is used to improve the surface texture of a part after a cut process. This may be
necessary to prep the part for plating, painting, or burnishing. This operation is similar to the cut process
with the exception of media bonds that are usually mild or non-abrasive, slower turret speeds, and
abrasive compounds between 240 and 1000 mesh. The surface texture of the part may have a low
micro-inch finish, between 4 and 10 Ra, with a dull or matted surface appearance.
4.1.3 Burnishing or Dry Buffing
To achieve deep luster and a bright polished color, a burnishing or dry buffing step must be used. The
fluent mass for this process ranges from low density media, such as ground and treated Walnut Shell
or Corn Cob used in Dry Buffing, to very high density media such as Steel or Stainless Steel shot or pin
utilized in a burnishing operation. The preferred fluent mass is between 100 lbs/ft3to 150 lbs/ft3, such

United Surface Solutions | 11901 Burke St, Santa Fe Springs, CA 90670 | [email protected] | [phone] Page | 15
as a porcelain bond media or a sintered ceramic. Depending on the required quality of the surface
texture, this operation can be performed at any stage of the finishing process. Unlike conventional hand
grinding or buffing, the transfer of material to flatten or smooth the part is minimal, if at all present in
burnishing. Therefore, the surface texture of the part must be refined to the desired quality, using rough
cut and refinement steps, prior to the burnishing or dry buffing step.
Burnishing
Burnishing is generally very short in cycle time, usually between 5 to 15 minutes. The action that is
taking place is the actual closure of microscopic fractures or scratches within the surface texture. For
this reason the characteristics of a high density, non-porous media is needed to develop a high luster
and bright color when processing in a wet burnishing application. Due to the high density of the media
used, the surface of the part will become hardened through a process called compressive stress. The
demand for parts which have undergone compressive stress is increasing in areas such as tool
manufacturing because of the increase in the life of end mills, taps, and bits. This process is used by
bearing manufacturers to increase the life of ball and roller bearings, bearing races, and journals. It is
also commonly used within the aerospace industry on jet engine turbine blades to increase efficiency
and longevity by offering a more refined surface texture.
Dry Buffing
In a dry buffing step, the closure of the microscopic peaks and valleys of any scratch or fracture must
be completed within the refinement step. This is due to the very low density of the media allowing a
minimal amount of energy transfer between the part and media particulate. A dry buffing operation
usually has a minimum cycle time of 30 minutes and does not offer the added benefit of compressive
stress. The deep color and luster that is developed yield excellent results for applications such as delicate
plating operations and fine jewelry.
For each step, cut, refinement, or burnishing / dry buffing, the fluent mass may occupy 30% to 100% of
the barrel volume, wherein the optimal range is 60% to 90%. Preferably, 80% of the barrel volume is
occupied by the fluent mass. The relative volume of the fluent mass determines the functional
parameters. If too little fluent mass is employed, the individual media particulate of the fluent mass is
imparted with too much energy; as it impinges the part, the surface is damaged. If the ratio of the fluent
mass to the part mass is too low, the parts will be more likely to impinge one another. Alternatively, if
too much fluent mass is employed within the barrel, insufficient energy is imparted to the media
particulate so that material is not removed from the surface of the part and the desired edge radius or
surface texture will not be achieved. With these factors in mind, the goal is to create a process with a
high amount of aggression as well as a high fluent-mass to part ratio in order to control media and/or
part-on-part impingement.
4.2 Compounds
It is important to understand the role that compound plays within any type of mechanical mass finishing
process. It is primarily used to clean media, not parts. Without the use of a soap-based compound, the
porous surface of the media will become clogged and glazed. This glaze will harden the surface and

United Surface Solutions | 11901 Burke St, Santa Fe Springs, CA 90670 | [email protected] | [phone] Page | 16
restrict the media from removing material from the part, rendering the media useless. The improper
use of compounds can develop a film on the parts yielding unacceptable results. The three basic types
of compounds are abrasive, detergent, and burnishing compounds.
4.2.1 Abrasive Compounds
To increase the aggression of the cut process, generally in shorter cycle times, an abrasive compound
such as Silicon Carbide, Aluminum Oxide, and Quartz or Pumice Stone, may be added to accelerate
material removal. The particulate size of the abrasive ranges from 30 to 1000 mesh. The size of the
abrasive particulate is based on the desired surface texture of the part. Abrasive compounds can be
purchased in the raw state or as premixed compounds usually having soap or detergent-based
additives.
4.2.2 Detergent Compounds
Used generally in aggressive cut down cycles, this high pH compound has very strong cleaning
characteristics to cleanse and preserve the media surface. These compounds have excellent durability
and maintain their properties under extreme conditions. The high pH of the compound assists in
preventing oxidization, although tends to darken the surface color of the part.
4.2.3 Burnishing Compounds
A major role in determining the color of the part is played by the burnishing compound. This type of
compound is mostly used in burnishing cycles along with high-density media such as sintered ceramic,
porcelain, or stainless steel. In some cases it may be used in a mild cut or refinement step in order to
maintain a smooth bright surface for plating or painting. The properties of these compounds are not
as strong as a detergent and may tend to break down in an aggressive process or one with long cycle
times.

5.3 Turret Drive Assembly
The turret of the CPC is driven using a double a-section v-belt that extends from the pulley on the main
motor to the flywheel on the turret. Under most circumstances, this belt will not require any dressing
or other conditioning. Periodically inspect the belt for signs of unusual wear and cracks. Cracks on the
top surface of the belt may appear once the belt stretches. This is normal and will not affect the
operation of the belt. If cracking appears on the underside or the “V” area of the belt, replacement of
the belt is recommended.
Check for excess wear on motor belt pulley, if the pully looks overly polished, the belt is loose.
WARNING: Always disconnect power and lock the main disconnect switch before doing any
maintenance or repair work.
Adjusting Main Drive Belt
The Gates Rubber Company recommends that the best tension for a V-Belt drive is the lowest tension
at which the belts will not slip under the highest load condition.
In this manner the method that is used by United’s technicians
is the twist method. The tension of the turret belt should allow
the technician to twist the belt to the halfway point. If the belt
can be twisted past the halfway point then the belt must be
tightened. If the belt does not twist to the halfway point excess
stress is being applied to the belt and bearings and may cause
these components to fail prematurely.
For belt adjustment follow the procedures below:
1. Turn OFF the power at the safety disconnect and lock the handle in this position.
2. Loosen the four (4) retaining bolts holding the main drive motor to the motor base.
3. Use the adjustment bolt on the rear of the motor base to move the motor backwards to tighten
the belt, or forward to loosen the belt.
4. Recheck the tension on the belt and adjust if necessary.
5. Retighten the four (4) retaining bolts holding the main drive motor to the motor base and torque
to 30 ft-lbs.
Note: It is important the motor remains parallel to the turret. Before retightening check motor with straight edge
or square for alignment with turret.
