Operation
Because of the higher maximum speed (approximately 9,000 RPM to 10,000 RPM) and variable speed control, the
Bench
Polisher
has several advantages over conventional single or two speed polishing and buffing machines.
1. The same size buffing wheel can be used to obtain different surface speeds, as measured in surface feet per minute
(SFPM). A 3" or 4" diameter buff can provide the 1,750 to 3,450 SFPM recommended for polishing and the 3,450 and
higher SFPM recommended for buffing. The chart below shows the SFPM obtained with different diameter wheels at full,
medium, and low speeds.
2. The SFPM can be varied while using the same wheel. This will give better results on different types of material.
3. The 10,000 RPM maximum speed will enable you to get much higher SFPM with smaller buffs such as 1" or 2" buffs or
inside ring buffs than slower single or double speed equipment.
4. The maximum speed of 10,000 RPM is also fast enough to permit the use of small mounted abrasive points, brushes,
cutters or other accessories in a collet holder.

Maintenance
Lubrication: This Bench Polisher has pre-lubricated ball bearings and a dustproof motor housing and does not require any
lubrication. The motor is designed to operate at about 40-50° F above room temperature which will be warm to the touch but will
not harm the motor.
Brush Wear: Disconnect power cord before checking for brush wear. Check for brush wear periodically (about every 100 hours of
continuous operation). The brush tubes are located under the two protective caps on the right hand side of the motor (as you face
it). Remove them with a standard screw driver blade, unscrew the brush tube caps, check the brush length, and install new
brushes if the old ones are less then 1/4" in overall length. Be sure that the radius in the end of the brush is in line and conforms
to the commutator surface.
