This control valve block module is used when the
tool is to be controlled remotely.
Both (1a) and (1b) detects a signal when the tool
is at the datum position.
External circuitry will be required to
control the speed of advance and retract
feeds.
When using simple control block replace
screw (35) with extended head screw
(383983).

PNEUMATIC MOTOR
A pneumatic motor from the Desoutter MR84
motor series is assembled on the AFD.
When using this AFD684 with the A1 control
1a
block, a valve kit (P/N 6153982820) has to be
ordered. The valve may be mounted remotely, or
1b
on the drill (on the control housing). Connect the
valve according to the circuit diagram.
When connecting the air supply to the motor,
refer to the instructions supplied with the motor to
obtain the required direction of rotation.
Accessories
Mounting Clamps
A range of clamps bases and columns are
3
available.
Full details obtained from Desoutter.
Hydraulic Check Unit (HCU)

The tool will function satisfactorily, when drilling a
blind hole at the set feed rate.
Should it be required to break through the
material and possibly through into another hole,
feed acceleration will occur with possible drill
breakage.
To obviate this, the fitment of an HCU is strongly
recommended.
Request information from Desoutter.
Peck Feed Drills
The Desoutter Peck Feed Drill System should be
used when the depth of the hole to be drilled is
five or more times the hole diameter.
This helps clear drill chips and avoids excessive
overheating of drill bit.
Hole size accuracy can be improved and drill bit
run-out can be kept to the minimum.
Request information from Desoutter.
SETTING DRILLING OPERATION
The drill must be at least 6mm (0.25in) above the
work piece.
