FAST APPROACH LEVER.
Depress for fast head
descent
FEED FORCE KNOB
Used to set feed force limit (counterclockwise
rotation to increase and clockwise rotation to
decrease).
FEED RATE KNOB (Fine Metering)
Used to set feed rate (counterclockwise
rotation to increase and clockwise rotation to
decrease).
HYDRAULIC FEED CONTROL
The Hydraulic Feed Control is located to the left of the control panel. These controls allow independent control of
Feed Force (FF) and Feed Rate (FR)
FF IS NOT APPLICABLE TO H40 MODEL
EXTRA FINE METERING VALVE
Used to set feed rate (counterclockwise
rotation to increase and clockwise rotation to
decrease).
The FINE METERING DDF VALVE is equipped with two Feed Control Knobs. Extra fine Micrometer style Knob and Fine
Metering Knob. The main difference between both Feed Controls is that the Extra Fine Metering valve does not work with
the Feed Force Limit Valve. It is recommended to use only one feed control at a time with the second control valve shut.
The choice of control is arbitrary and a matter of trial.
In some cases Extra fine Metering provides better results in others Fine Metering Control.
As a rule of thumb:
Extra Fine metering valve should be used
•
if required feed is in a range of .12-.25”/min
•
and/ or when cutting hard material
•
or when work hardening may occur.
Fine metering valve should be used
•
When cutting structural steel
•
and/ or bundles
•
High feed rates required
