Mounting The Milling Cutter On The Compound; Height Adjustment Of Spindle (Fig. 8); Height Adjustment With The Handwheel; Working With The Drilling Lever - Proxxon PF 250/BL Manual

3.2 Mounting the milling cutter on the compound

table (Fig. 7 and Fig. 7a)
1. Attach compound-type table to work surface using 4
screws 1 (M4, not included) (Fig. 8).
2. When working in conjunction with the PROXXON
PF 230 milling machine, insert pillar in flange and clamp
using screws 2.
4 Working with the milling cutter
Before carrying out any adjustment work, switch off the
device and disconnect the plug to prevent inadvertent
starting up!

4.1 Height adjustment of spindle (Fig. 8):

The spindle of the PF/FF 250/BL can be adjusted in height in
2 ways:
1. With handwheel 1
2. With drilling lever 2

4.1.1 Height adjustment with the handwheel

1. Release clamping screw 3 (Fig. 9).
2. Adjust the desired height with the handwheel 1 (1 revo-
lution corresponds to 1mm feed).
3. Re-tighten the clamping screw 3

4.1.2 Working with the drilling lever

4.1.2.1 Easy drilling with the drilling lever:

1. Ensure that the screw 6 at scale ring 6 is loosened.
2. Release toggle screw 4
3. Swivel the drilling lever 2 to place the quill in the
required position. The quill is spring-loaded and returns
automatically to its top position after machining.
1. Release the screw 6 at the scale ring.
2. Press down the drilling lever 2 until the bits and cutters
lightly touch the surface of the work piece.
3. Set the scale of the scale ring 5 to "0" and tighten the
screw 6.
Note:
Attention:

4.1.2.2 Drilling with limit stop function:

1. Release the screw 6 at the scale ring.
2. With the machine switched off, set down the bits and
cutters very lightly on the surface of the work piece.
3. Set the required machining depth with the scale ring at
4. Tighten screw 6.
the marking on the machine.

4.2 Spindle fine feed Art. No. 24140 (Fig. 9)

Fitting the fine feed is simple:
1. Insert the shaft on the fine feed into the drill hole for the
drill lever shaft on the milling cutter. During assembly, it
is essential to observe the following: The "spring" on
the fine feed 2 fits into the slot on the drill lever shaft 3.
2. Align the fine feed and secure it with the screw
provided.
3. You can now switch the fine feed on or off with the cou-
pling shaft. To switch on, press your finger on the shaft
(4) and turn the handwheel at the same time.
4. The spring clicks into position in the slot. To switch off
the fine feed, simply pull the coupling out again.

5 Swivelling the milling spindle

5.1.1 Swivelling the milling spindle around the
vertical axis (Z axis, Fig. 5)
The entire milling spindle can be swivelled around two axes.
To swivel around the vertical axis (Z axis), loosen screw 2
(Fig. 5) and turn the column completely to the required posi-
tion. Then re-tighten the screw.
Caution!
