The Foredom 350K2 Air Turbine Handpiece is capable of generating 350,000 RPM
(revolutions per minute). Rotation is accomplished by forcing air at a maximum rate
of 40 P.S.I. (pounds per square inch) across an impeller or turbine which
holds the collet.
The unit generates substantial speed, but little torque, which makes it ideally
suited for operations such as cutting, carving, engraving, texturing, and fine detailing
with carbide or diamond points on materials such as metal, bone, stone, porcelain,
plastics, glass and hard woods.
A delicate touch is required on softer material and woods, or the bur will bury itself
and stall the handpiece– as is the case when too heavy a cut is attempted.
Filtered and regulated air is fed into the handpiece through an on/off foot pedal, or
the air flow can be shut off and on at the regulator. Clean, dry air is an absolute
requirement to the efficient running of this machine, as any foreign particles
generated by or from the air source (compressor) will be thrown into the turbine and
eventually clog and/or damage it.
With proper use and maintenance, the Foredom 350K2 Air Turbine can give a life
time of use. However, if a few simple basics are not observed, like any other fine
instrument or machine, the unit will eventually develop problems that will become
exaggerated if not corrected.
Be sure that the tubing you use to connect the filter/regulator to the air source is
rated for the output pressure of the compressor. The unit requires a minimum of 1.5
C.F.M. (cubic feet per minute) of air at 40 P.S.I. (1/4 HP Compressor) which is also
the recommended operating pressure. If you have purchased a handpiece only, you
must install an industrial filter/separator in the air line. As air is being compressed in
the compressor, heat is generated that causes a temperature differential between
raw air and compressed air that introduces moisture into the system which, in turn,
is forced with the air into the air line feeding the handpiece. Without an in-line
separator/filter, impurities such as moisture or dirt are carried with the air and
forced against the turbine impeller in the handpiece and will damage the turbine.
Installation
1. Beginning with the compressor (not included), run a supply hose (not included)
from the compressor to the Filter/Regulator bracket marked “IN”.
2. Insert a length of air line (clear tubing) from the feed nozzle marked “Out” on the
Filter /Regulator to the source nozzle marked “IN” on the Foot Pedal. If necessary
cut the air line to a convenient length. Some applications may require the air line to
be secured along its length with mounting brackets to keep the line out of the way of
other area activities.
3. Insert the free end of the handpiece hose into the air hose adapter (HP91002).
