Foredom BL - Manual (Page 3)

Operation
Because of the higher maximum speed
(approximately 7,000 RPM) and variable
speed control, the Foredom ® Bench Lathe
has several advantages over conventional
single or two speed polishing and
buffing lathes:
1. The same size buffing wheel can
be used to obtain different surface
speeds, as measured in surface feet per
minute (SFPM). 3 ″ or 4″ diameter buffs
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 various speeds.
2. The SFPM can be varied while using the
same diameter buff or wheel. This will
give better results on different types
of material.

Cotton, chamois or felt buffs over 4 ″ in diameter should not be used with the Bench Lathe.

3. The 7,000 RPM maximum speed will enable
you to get much higher SFPM with smaller
1 ″ or 2″ buffs or inside ring buffs, than
slower single or double speed equipment.
4. 3M Scotch-Brite™ Radial Bristle Discs in 2″
and 3 ″ diameters require 5,000 or higher
RPM for optimum performance, making
them perfect for use in the lathe.
5. The maximum speed of 7,000 RPM is also
fast enough to permit the use of small
mounted abrasive points, brushes, cutters,
or other accessories in the A-CHA-5 collet
holder, S.B0-516 flexade or A-JCA-2
chuck holder.
