Functional Overview
The Model RML-1640V High Precision Electrical
Variable Speed Lathe that has a pressurized headstock
oiling system. The electrical and mechanical controls
allow for complete spin dle speed control from 20
to 2500 RPM. Merely shift one lever to high or low
range, and then just turn the spindle speed dial to
your needed RPM.
This lathe is also equipped with a CSS system that
gives consistent
fi
nishes between surfaces with
different diameters. During facing operations, as the
tool bit moves toward the center of the workpiece,
the spindle speed increases to maintain a constant
surface speed during cutting as diameter decreases.
The lathe gearbox has a selection of
fi
ve levers that
control the speed and direction of the leadscrew
and feed rod. When threading or power feed turning
operations are selected, the carriage moves left or
right, or the cross slide will move in or out.
A feed direction quick change knob on the apron
allows for feed direction changes during power fed
operations without having to shut the lathe down
and shift the feed direction lever on the headstock.
A hand-operated oil pump allows for easy carriage
lubrication, and for speedy machine shutdown, a foot-
pedal brake system is used.
When cutting
fl
uid is required, the built-in coolant
pump and delivery nozzle directs the coolant to the
point of cut. As cuts are made, the chips fall into the
chip catch drawer, which slides out for easy cleaning.
