Machining Work Pieces; Operation; Tool Change; After Operating - Proxxon BFW 40/E Manual

For your safety, always wear
hearing protection while working!
For use in dry environments only
Protection class II device
Please do not dispose off the machine!

Operation:

The motor must only be operated with the accompany-
ing safety voltage supply unit (40 volts DC). There is a
risk of injury if used with another voltage supply unit.
Mounting on a drilling or milling stand:
Safe and precise operation is only possible if the ma-
chine is properly fastened in a stable drilling or milling
stand. The drilling or milling stand must be securely fas-
tened to a table top. For safe and precise operation, we
recommend the PROXXON BFB 2000 drilling and
milling stand in conjunction with the KT 150 compound-
type table.
Disconnect the power cable or the motor connecting
lead before all operations on the machine.
1. Insert the machine in a secure drilling stand (Fig. 2)
and tighten the clamp.
2. Connect the voltage supply unit to the mains using
the power cable.
3. Ensure that the voltage supply unit is switched off.
4. Connect the machine to the voltage supply unit.

Tool change

The collet chuck and the milling shaft must be of the
same diameter, otherwise the collet chuck could be
damaged.
1. Put the locking pin (1) into the requisite hole in the
lower flange (see Fig. 3). If necessary, rotate the
motor shaft to find the cross-hole in the shaft.
2. Insert the locking pin fully.
3. Use the key (2) provided to turn the flattened
coupling ring (3) (see Fig. 3) and remove the tool
from the collet chuck. Insert the new tool and once
again carefully tighten the coupling ring. Ensure
when doing this that the correct collet chuck had
been inserted into the shaft.
4. Remove the locking pin from the hole.

Attention!

Machining work pieces:

1. Adjust the milling guard on the drilling stand so that it
forms a barrier between the milling tool and the oper-
ator.
2. Securely clamp the work piece using holding straps
or a machine vice.
Ensure that the milling tool or drill is not touching the
work piece before switching on the motor.
Only use sharp tools. Blunt tools impair the quality of the
results and overload the motor.
Switch off the motor immediately if the tool becomes
blocked.
3. Switch on the voltage supply unit.
4. Set the required speed on the voltage supply unit.
5. Switch on the motor by pressing button 7 (Fig. 1).
The voltage supply unit is equipped with overload pro-
tection. If the overload protection is activated, disconnect
the mains plug for the voltage supply unit and allow the
unit to cool for 5 to 10 minutes.
Caution: Switch off the motor and ensure that the milling
tool or drill is not touching the work piece before re-con-
necting the power cable.
Good results can only be achieved with correct and uni-
form speed. Therefore, never overload the motor
through excessive rate of feed or depth of cut.
The feed must always be against the cutting direction of
the milling tool.
6. Feed for milling a rectangle (Fig. 4)
7. Feed for milling edges (Fig. 5)
8. Feed for milling a rebate (Fig. 6)

After operating:

1. Switch off voltage supply unit.
2. Thoroughly clean cuttings and dirt from the machine
using a brush and a dry cloth. Lightly grease or oil
collet chucks, union nut and mounting in order to pro-
tect against corrosion.
No grease or oil must enter the motor.
