Connecting The Dust Exhaust (Fig. 6); Working With The Tg 125/E Disc Grinding Machine; Working With The Angle Stop (Fig. 7); 6.2 Notes On Grinding Speed - Proxxon TG 125/E Mode D'emploi

5.5 Connecting the dust exhaust
(fig. 6):
Before connecting the dust exhaust, always dis-
connect the mains plug to prevent the disc
being started up accidentally. Risk of injury!
It is recommended to always work with the dust
exhaust! This not only guarantees clean
working, it also reduces the hazardous effect of
some dusts!
1. Push adapter piece 1 onto connecting piece
2 of the machine
2. Push rubber adapter 3 onto adapter piece 1
3. Insert vacuum cleaner nozzle 4 into rubber
adapter 3
4. Switch on vacuum cleaner when working
Another small tip:
When using the Proxxon CW-matic vacuum
cleaner, manual switching on and off is no
longer necessary. The CW-matic is fitted with
an automatic control device; it automatically
switches on and off when the power tool is
switched on and off. The same effect can be
obtained with traditional vacuum cleaners by
using our vacuum control device.
6 Working with the TG 125/E disc
grinding machine
1. If mitres are to be ground, adjust the grinding
angle as described above
2. Insert the mains plug
3. Switch on the machine at On-Off-Switch
4. Set the required speed on the speed control
button (pos. 3, fig. 1)

6.1 Working with the angle stop (fig. 7):

If, for example, the ends of somewhat thinner
strips are ground for mitre, it is advantageous to
- 14 -
Caution:
use the angle stop included in the scope of deli-
very.
1. Loosen knurled screw 1
2. Set the desired angle on scale 2
3. Turn the knurled screw tightly and insert into
the intended table groove
4. Guide the desired workpiece up to the stop
against the grinding wheel as shown in the
illustration

6.2 Notes on grinding speed

The grinding speed of your TG 125/E is infinitely
adjustable from approx. 250 – 800 m/min. In
this way, optimal adaptation to various material
conditions is possible. Please note that the
circumferential speed of the grinding disc is
greatest at the edge and reduces towards the
middle.
General recommendations on the selection of
the grinding speed are difficult; it may be
necessary to experiment somewhat to find out
the correct grinding speed for "its" material and
workpiece.
Based on experience, non-ferrous metals and
plastic require lower grinding speeds than soft
and hard wood; this also applies for ceramics
and glass.
But as stated: Recommendations are difficult,
the correct speed depends on the material,
contact pressure and friction and grain size of
the grinding wheels.

Care and maintenance

Before cleaning, adjusting, service or repair, dis-
connect the mains plug!
Note:
The machine is largely maintenance free. To
ensure a long service life, however, the machine
should be cleaned with a soft cloth, handbrush
or paintbrush after each time it is used. A
Caution:
