Parting A Workpiece (D); Machining Longer Workpieces With Tailstock; And Lathe Centre (Fig. 12); Repair And Maintenance - Proxxon FD 150/E Manual De Uso

Parting a workpiece (d)

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 rotary axis 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 rotary axis of the workpiece, it is separated.
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, a centring 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 5 as described
in the chapter "Inserting the drill chuck" and clamp a centring
drill.
4. Release the clamping lever 2 and move the tailstock 6 with
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 3 to the
right on the tailstock and lightly push the centring drill in the
workpiece with the quill. Switch off the machine.
6. Move the quill 5 back with the handwheel 3 until the cone of
the drill chuck releases. Exchange the drill chuck for the trav-
elling lathe centre 1.
7. Move the travelling centre 1, or the tailstock 6 up to the work-
piece. Please note that the clamping lever 2 is clamped after
having been pushed up to the workpiece.
8. Infeed the quill with the handwheel 3 until all play is elimi-
nated.
9. Block the quill with the help of the knurled screw 4.

Repair and Maintenance

Cleaning

Always disconnect the mains plug for all adjustment and main-
tenance work! Risk of serious injuries or damage due to inad-
vertent starting up of the device, or hazard due to electric shock!
1. After use, thoroughly clean all chips from the machine using
a brush or handbrush. Do not use compressed air for clean-
ing.
2. Regularly lubricate or oil all moving parts, spindles and
guides!
Caution!
Caution:
Caution!
The outside of the housing can be cleaned with a soft, dry or
damp cloth. It is possible to use mild soap or other suitable
cleaning agent here. Solvents or cleaning agents containing al-
cohol (e.g. petrol, cleaning alcohol etc.) should be avoided, since
these can attack the plastic housing casings as well as wash off
the lubricants.

Adjusting the play of the guides (Fig. 13)

Even if the guides are regularly lubricated or oiled, it is un-
avoidable that the guides will exhibit play after some time due to
wear.
The procedure described here using the example of the upper
carriage is the same for all guides, therefore it applies analo-
gously to the other guides on your lathe. For that reason they will
not be treated separately here. Adjust the guides according to the
motto: As "tightly" as necessary, as easy running as possible!
Please consider: If guides are set too closely, this causes high-
er operating forces as well as increased wear!
1. Release and slightly unscrew the counter nuts 1 (Fig. 13) of
the adjusting screws 2 for the upper carriage 3 using an open-
end spanner 5.
2. Evenly turn in the adjusting screws 2 with an Allen key 4 un-
til the play is eliminated.
3. Retighten the counter nuts 1. In the process, hold the ad-
justing screws 2 in position with the fixed spanner 5 so that
they do not misadjust again.
4. Then check if the support can still be moved easily and if it
runs completely without play.

Adjusting the play of the handwheels (Fig. 14):

Just as for the guides, handwheel wear during operation cannot
be avoided which ensures that the backlash increases slowly
but consistently. To minimise this again, please proceed as fol-
lows:
1. Hold on to the handwheel 1 and release the cap nut 2.
2. Turn the handwheel slightly to the right.
3. Retighten the cap nut while still holding the handwheel.
Please consider here as well:
The complete elimination of the backlash and a too "tight" ad-
justment for the handwheels is unreasonable: If the handwheels
are set too closely, this causes higher operating forces as well
as increased wear here as well!
