Rotating Milling Spindle; Installation Of The Collet Chucks; Setting The Spindle Speed; Milling - Proxxon PF 230 Mode D'emploi

4. The spring clicks into position in the slot. To switch off
the fine feed, simply pull the coupling out again.
Moveable scaling ring:
The moveable scaling ring 5 can be set to "0". In this way,
you can precisely set the desired feed from any position. A
rotation of the handwheel corresponds to a feed of 1.5mm,
the distance between two large scale divisions is 0.1mm.

Rotating milling spindle

The entire milling spindle may be rotated along 2 axes. To
rotate along the vertical axis, loosen screw 4 (Fig. 6) and
rotate entire pillar to the desired position. Then retighten
screw.
To rotate along the horizontal axis, loosen screw 1 (Fig. 10)
and rotate milling spindle to the desired position. Adjust to
the desired degrees on scale 2 and retighten screw 1.

Installation of the collet chucks

Important!
Never insert the collet chuck alone into the spindle! Always
engage the collet chuck into the nut first! Always ensure
that collet chuck and milling tool have the correct diameter
for proper fit.
Please note: Further collet chuck dimensions are available
as accessory equipment in addition to those collet chucks
supplied. These are listed in our equipment catalogue.
Please consult our customer service department for further
information.
1. Loosen union nut 7 (Fig. 11).
2. Place desired collet chuck 2 into union nut and allow to
engage.
3. Insert union nut with collet chuck in the spindle and turn
slightly by hand.
4. Insert milling tool into collet chuck.
5. Lock milling spindle using the spanners supplied and
tighten union nut.
6. To remove collet chuck loosen union nut and remove
milling tool.
7. Now remove union nut with collet chuck completely from
milling spindle.
8. Disengage collet chuck using light sideways pressure 3
(Fig. 11) and remove from union nut.

Setting the spindle speed

Important!
Disconnect the mains plug before making any adjustments
on the milling machine!
A total of 6 spindle speeds may be adjusted by shifting
the V-belt (Fig. 12 a/b): 280, 540, 780, 910, 1710,
and 2500 rpm.
Tighten belt only lightly! A belt installed too tightly places
excessive loads on the motor and machine mechanical
system!

Note:
1. Loosen knurled screw 4 (Fig.13) and open cover 7.
2. Loosen screw 5 using Allen key 1 by approx. 2 turns in
order to release belt pulley tension.
3. Place both belts in the desired position.
4. Press belt pulley 1 outwards with the belt tightener 8
below the gear wheels until the belt is tight. Tighten
screw 5.
5. Should both belts be tensioned unevenly, the upper belt
may be tensioned separately. To do so, loosen screw 2
and push motor 3 outwards until upper belt is tensioned.
6. Retighten screw 2.
The belt cover must always be closed during operation.

Milling

Always wear protective goggles when milling. Always
observe the enclosed safety regulations.
1. Securely fasten the work piece using clamps, in a vice,
or to the support of the lathe chuck.
2. Alternatively, you can clamp the work piece in a machine
vice and mount the vice on the work table using the
T-grooves.
3. Adjust desired milling depth.
4. Tighten clamping screws 3 and 4 (Fig. 9).
5. Ensure that the milling tool does not touch the work
piece.
6. Ensure that the proper spindle speed has been adjusted.
7. Switch on milling machine at switch 3 (Fig. 1).
8. Work using a suitable feed
When milling, always ensure that the feed is against the
cutting direction of the milling tool (Fig. 14).
Always provide feed by hand only! When using the milling
machine in conjunction with the lathe PD 230/E, feed
action must not occur via the lathe's automatic feed. Risk
of injury!

Repair and maintenance

Disconnect mains plug prior to all repair and maintenance
work!

Belt replacement

If the belts are worn, you can replace these yourself.
Replacement belts are available from PROXXON Central
