Caution!

Avoid abnormal body posture! Make sure you stand securely and

can keep your balance.

Caution!

Only work with afolded down chuck guard! If the guard is de-

fective, the machine may no longer be operated!

Example of straight turning (a)

Note:

Turning parallel to the rotaryaxis and machining cylindrical ob-

jects are the main applications of alathe.

1. Clamp the workpiece as described in the chapter "Clamping

the workpiece".

2. Make sure that the workpiece can be turned freely.

3. Set the necessaryrotational speed by shifting the belts in the

gear case (see previous section). Caution: Turn the rota-

tional speed regulating knob to the left before switching on.

4. Clamp the appropriate tool in the tool holder (see "Clamp-

ing the cutting tool").

5. Move the support to the workpiece from right to left.

6. Set the cutting depth with the cross slide 1.

7. Move thecross slide and upper carriage up to the work-

piece.

8. Switch on themachine using the master switch. Caution:

Make sure that the chuck guard is folded down.

9. Traverse the cross slide and upper carriage by turning the

handwheels. Caution: Do not let the carriage or cutting tool

run against the lathe chuck!

10. When you have completed your work, use the master switch

to shut off the machine.

Example of face turning (b)

Note:

This operating method is used to face turn the face side of a

workpiece. To do so, proceed in the manner of the previously de-

scribed straight turning with the following particularities:

1. Clamp the right cutter adjusted by approx. 2° to 3°. The an-

gle adjustment must be set by swivelling the tool holder.

2. Move the cross slide with cutting tool from the outside to the

inside (towards the centre) while machining the right face or

shaft shoulders.

Caution!

For larger workpiece diameters, the cutting speed from the out-

side to the inside differs rather considerably.Therefore, infeed

the cutting tool with the cross slide slowly and with sensitivity!

Example of taper turning (c)

The upper carriage is equipped with ascale and can be swivelled

to two sides by 45° for taper turning. To do so, proceed as de-

scribed at "Working with the upper carriage". The method of ma-

chining is the same as for straight turning.

Parting aworkpiece (d)

Caution!

Insert the parting tool as far as possible when clamping. Pay at-

tention to the exact height of the parting tool cutting edge! This

should be at the level of the rotaryaxis or just slightly below it!

1. Clamp the parting tool at right angles into the tool holder.

2. Move the cross slide with the cutting tool with sensitivity

from the outside to the inside (towards the centre). When it

passes the rotaryaxis of the workpiece, it is separated.

Caution:

Proceed with great caution here to prevent the separated work-

piece from flying around. Risk of injuries!

Machining longer workpieces with tailstock

and lathe centre (Fig. 12)

1. For this purpose, acentring hole must be drilled on the right

side of the workpiece.

2. Face turn the right face side as necessary.

3. Insert the drill chuck (accessory) in the quill 5asdescribed

in the chapter "Inserting the drill chuck" and clamp acentring

drill.

4. Release the clamping lever 2and move the tailstock 6with

drill chuck and centring drill close to the front face of the

workpiece. Retighten clamping lever 2.

5. Switch on the machine and drill the centring hole with the

help of the quill feed. To do so, turn the handwheel 3tothe

right on the tailstock and lightly push the centring drill in the

workpiece with the quill. Switch off the machine.

6. Move the quill 5back with the handwheel 3until the cone of

the drill chuckreleases. Exchange the drill chuck for the trav-

elling lathecentre 1.

7. Move the travelling centre 1, or the tailstock 6uptothe work-

piece. Please note that the clamping lever 2isclamped after

having been pushed up to the workpiece.

8. Infeed the quill with the handwheel 3until all play is elimi-

nated.

9. Block the quill with the help of the knurled screw 4.
