This section is devoted to working with flap wheels. When working with a flap wheel, the spindle speed does not need to be adjusted as the tool wears. The shorter the flaps become, the stiffer they are, thereby compensating for the reduced surface feet per minute. The cutting and finishing action of flap wheel is the same from the time a new wheel is put into use until the wheel is removed.
Pressure: Optimal operating pressure for a flap wheel
is between 12 and 15 pounds. When using a flap
wheel on automatic machines, the tool head should
float or be cammed.
The flap wheel does not need to be pre-shaped
when used on automatic machinery. The new tool
will quickly take on the shape of the item being
polished.
Note: If your prefer to shape the flap wheel in your
operations it can be readily accomplished by
covering the object with a course grained abrasive
cloth and holding it against the rotating flap wheel.
When using a flap wheel on a hand operation the tool can be quickly shaped by using a coarse grit, abrasive cloth wrapped around the item to be polished and held against the wheel.
The flaps of a flap wheel retain their cutting efficiency until the wheel is completely worn down, thereby greatly reducing down time due to abrasive change.
