Adjustment of the milling spindle

The milling spindle of the PF 230 canbe height-adjusted in

2 ways:

1. By using the fine feed 1 (Fig. 9)

2.By using the drilling lever 2

Verticaladjustment viafine tolerance feed

1. Loosen screw 3 (Fig. 9).

2.Adjust to the desired height using the hand wheel 1

(1 rotation corresponds to 1 mm feed).

3.Screw 3 must always be tightened again.

Feed via the drilling lever

1. Loosen screw 4(Fig. 9).

2.Loosen screw 6 and set scale 5 to zero.

3.Retighten screw 6.

4. Adjust to the desired height using the drill lever 2.

5. Retighten screw 4.

Note:

The drilling lever is not just used for height adjustment.It

canbealsobe used for drilling. Do not tighten the screw 4

when drilling.

Swivelling the milling spindle

The entire milling spindle canbe swivelled around twoaxes.

To swivel around the verticalaxis, release screw 4(Fig. 6)

and swivel the column completely into the required position.

Then retighten the screw.To swivel around the lateral

axis, release screw 1 (Fig. 10)and swivel the milling spindle.

Set the required number of degrees on the scale 2 and

retighten screw 1.

Assembly of the clamping devices for the milling machine:

Impor tant

Never insert the collet chuckalone into the spindle! Always

engage the collet chuck into the nut first!Always ensure

that collet chuckand milling tool have the correct diameter

for proper fit.

Please note:Further collet chuck dimensions areavailable

as accessory equipment in addition to thosecollet chucks

supplied. Theseare listed in our equipment catalogue.

Pleaseconsult our customer service department for further

information.

W arning:

Use only accessories recommended for this milling machi-

ne. Follow the instructions that accompany accessories.

Use of improper accessories may cause hazards!

1. Loosen union nut (7, see Fig. 1).

2.Place desired collet chuck 2:(see Fig. 11) into union nut

1and allow to engage.

3.Insert union nut withcollet chuck in the spindle and turn

sightly by hand.

4. Insert milling tool intocollet chuck.

5. Lock milling spindle using the spanners supplied and

tighten union nut.

6.To removecollet chuck loosen union nut and remove

milling tool.

7.Now remove union nut withcollet chuckcompletely from

milling spindle.

8. Disengage collet chuck using light sideways pressure 3

(Fig. 11) and remove from union nut.

Setting the spindle rotational speed

A total of 6 spindle speeds may beadjusted by shifting the

V-belt (Fig. 12 a/b): 280,540, 780,910,1710, and 2500

rpm.

Note:

Tighten belt only lightly!A belt installed too tightly places

excessive loads on the motor and machine mechanical

system!

1. Loosen knurled screw 4 (Fig.13)and open cover 7.

2.Loosen screw 5 using anAllen key by approx. 2 turns in

order to releasebelt pulley tension.

3.Placebothbelts 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 bothbelts 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.

Important:

The belt cover must always beclosed during operation.

Only tension the belts lightly.A too highly tensioned belt

strains the motor and the mechanics of the machine!

Replacement belts areavailable from the PROXXON central

service team (address on the rear side of these

instructions).
