ith the introduction of the new Carlton-Leber speed-
feed programming and pre-selector systems, you can now
take your choice of three speed-feed controls: programming,
pre-selector or manual.
Programming works like this: your production engi
neering department studies the workpiece drawing and
determines the sequence of drilling operations and the correct
speed and feed for each. This data is recorded on a routing sheet
or blueprint and is transferred to the programming console.
The programming console contains an indexing dial

which shows the operation sequence number being per
formed. Operator has local control and can perform
operations out of sequence by manually advancing or
reversing the indexing dial.
Pre-selector:
jobs, the programming unit can be disconnected through
a selector switch and the pre-selector then becomes
operative. The pre-selector saves time by
to select speed and feed for the next operation while the
machine is under cut. Pre-selector may be furnished with
or without the programming unit.

Manual gear shift: Selects speed-feed combina

using two speed shifter levers and two feed shifter levers.
