IMPORTANT: READ BEFORE OPERATING UNIT
1. SHIPPING BOLTS AND SPACERS MUST BE REMOVED BEFORE WIRING the Variable AC
Motor Drive or operating the machine. Damage will occur to unit and motor if oper-
ated without removing the shipping bolts and spacers.
2. Shut off and lock out power before removing any machine guards or doors.
3. All doors and guards must be kept in place at all times during operation of the
machine to avoid exposure to parts rotating at high speeds. Severe injury can occur
if hands or feet reach inside unit while power is on.
4. To avoid electric shock, attach ground lead, labeled “0” in power cord to ground.
NEVER REMOVE grounding strap to bowl unit.
5. Securely tighten all bolts/nuts on vibrating unit according to instructions in this manual.
Special attention must be paid to motor mounting bolts. If a motor vibrates loose,
damage to power cord and structure may result as well as risk of personal injury.
6. When maintaining or adjusting eccentric weights, extreme caution must be used to
correctly attach all keys, retainers and fasteners. Failure to lock weights securely in
place can result in parts being thrown from machine at high speed, endangering
personnel.
7. Higher amplitudes occur during machine start up and shut down. Caution should be
taken to provide adequate clearance from accessory equipment to avoid contact
during these cycles.

FUNCTION:
The CB-30 planetary barrel, centrifugal polisher features high-efficiency, ease of operation,
wide operating speed range and low noise level all in an attractive machine enclosure.
The planetary drive system is composed of four groups of hexagonal barrels that can be
unloaded. When the motor drives the planetary drive system, the barrels revolve on inde-
pendent axis in opposite directions to create a dual centrifugal working force that is ideal
efficient and uniforrn chamfering, deburring and polishing. The barrels are made of alufer
or steel and are attractive and ease to load and unload. The serrated drive belts are
made of steel wire and polyurethane for smooth and quite operation.
MACHINE COMPONENTS OVERVIEW:
The machine is composed of cover, basement, control panel, media trough and rotary
barrel plate assembly.
The cover is welded steel plate with shutters on both the left and right side. The front side
sliding door is equipped with an electromagnetic safety lock. The contol panel on the right
side of the unit must be separated from the cover and dismantled before separating the
cover from the base of the machine, otherwise the electric circuit can be damaged.
The basement is constructed of welded steel plate. The motor base is fixed with a bolt
welded to the bottom of the basement and the motor base can be moved up or down
along the bolt to adjust the motor belt tension. The upper part of the machine base is
connected to the rotary barrel plate assembly and cover.
On the inner right side of the machine is the barrel turing device and at the center of the
unit is a media trough for loading the mixture of workparts, water and media. There is a
hand-brake to serve as a back-up to the electromagnetic brake.

Machine Components
MACHINE COMPONENTS (cont’d):
ROTARY BARREL PLATE ASSEMBLY
The rotary barrel plate assembly is composed of belt assembly, rotary plate assembly,
chief axis, gear and chain assembly and four-barrel groups. There is a wobler on the lock-
stem. Place the stem into the holes on the side of the barrel base. Move the right side of
wobler downward to tighten the barrel in position using helper on wobler arm. Move the
other wobler equipped with a spring upward to tighten and secure the lock-stem. The
barrel is secured in base for safe operation. The interior PU cartridges can be changed
when they are worn out. The barrels are rotated by the turning device composed of motor,
decelerator and gear.
ELECTRIC CABINET
The electrical cabinet is constructed of welded steel plate and fixed by arch steel to the
base of the machine. To remove the cover, screws on both sides of the cabinet must first
be loosened and the cover rotated 20º to clear the elctrical system. The electrical cabi-
net is fixed on the right side of the machine base.
WORKING PRINCIPLE
When the motor drives the rotary plate and planetary gear groups, the barrel groups
revolve on independent axis in the opposite directions creating dual centrifugal forces
that create an efficient and uniform chamfer, debur or polishing action.
ELECTRICAL SYSTEM
The machine is equipped with a world-class inverter. Control panel adjustment of the
rotary plate assembly can be made to match specific speed requirements of different
workparts. The barrel angle can also be adjusted downward using the control panel to
facilitate unloading. The unit is also equipped with an AC electromagnetic brake and a
two-way ON/OFF switch for safe operation. When the sliding door is open the main motor
is stopped but the barrels can be rotated to facilitate unloading. When the sliding door is
closed the rotary plate and barrels are locked in position and cannot be adjusted.

IMPORTANT: Installation Tips
The machine should be installed on a smooth and level concrete floor. All mounting feet
must touch floor or should be shimmed with steel shims.
The motor winding, the magnetizing windings and the speed windings should be tested
using 500 ohm megameter, the insulation must be over 0.38 megaohm. otherwise it
should be dried.
When the power is ON. the barrel assembly should be rotating counter-clockwise or from
the top of the unit toward the bottom. Make sure the grounding wire is attached and in
good condition.
Check the tightness of the barrel chain by adjusting the bracket of the decelerator.

IMPORTANT: Read this section prior to machine operation.
Use the buttons on the control panel to arrange the barrels in the desired position. To
empty the unit of workparts and media, first remove the lock bar from the steel jacket. The
barrel can be angled foward 15º to pour out media and workparts.
To load the unit. Open the barrel cover and load degreased workparts and media in a
ratio of 1:2 into the barrel. The volume should be roughly 70% of the barrel capacity.
Next add compound and water to a height just above the workparts and media. Finally,
put the cover evenly into position and fasten the lock bar to prevent water from leaking
out of the barrel.
Put the barrel into the barrel base, and lock the bar into the two holes, the inner hexagonal
bolt should be vertical to the upper side of the barrel, then evenly fasten the barrel to the
bottom of the barrel base through inner-hexagonal using spanner.
Shut the sliding front door after all four barrels (or two opposite barrels) have been readied,
then adjust the rotary plate to the correct speed using the buttons on the control panel.
IMPORTANT: All four barrels or at least two barrels opposite to each other should be loaded
to safely operate the machine. Otherwise the unbalanced barrels will cause excessive
vibration and could damage the machine.

IMPORTANT: Key tips for proper maintenance & service
1. Keep all parts of the machine clean and oil free.
2. Once a month, check the tightness of all bolts.
3. Every 500 hours add 30 grams of ZL-3 calcium-based lubricant to all bearings on
machine properly
4. Periodically check the tightness of the motor belt and driving chain, adjust them if they
are not fitting
5. Check and adjust the tightness of the electromagnetic lock if and when it is not stop-
ping the machine efficiently.
6. The two ends of the barrel bar must be totally in the holes before you fasten them.
Make sure the bar is securely tightened.
7. If abnormal noise occurs during operation, check all bolts and bearings to ensure they
are in proper working conditon and securely tightened.
