CHANGING GEARS FOR SCREWCUTTING
The leadscrew is driven via a gear train and by a gear on the spindle. The gear
ratio will therefore determine the rotational speed of the leadscrew with
relation to the spindle. i.e. one turn of the spindle will turn the leadscrew an
amount determined by the gear ratio.
By setting the gears to a known ratio, we can therefore produce threads to a
known size, and as the leadscrew supplied produces Imperial threads, the
known values will be in Threads Per Inch (TPI).
A leadscrew for Metric thread cutting complete with half nuts is available from
your Clarke dealer.
As previously mentioned, the actual thread produced will be totally
dependant upon the profile of the cutting tool. It is not within the scope of this
manual to provide detailed information regarding types of cutting tool,
cutting speeds and working with various types of material etc, and it is strongly
advised that you consult appropriate handbooks or seek advice from a
qualified person.
The chart overleaf, shows the thread sizes that may be cut using the gear
configuration shown in the corresponding columns.
