2Description of the machine

Thank you for purchasing the TG 125/E disc
grinding machine. Younow own ahigh-preci­sion machine to use in grinding work for which
complete accuracy is required.

Ahigh-precision manufactured and carefully
balanced grinding disc with double ball-bearing
direct drive guarantees excellent smoothness,
precision concentricity and minimum wear.

In this way,soft and hardwoods, plates, non­ferrous metal or steel, even plastic, cork, rubber
and many further materials can be processed
with high precision at grinding speeds of
approx. 250-800 m/min (adjustable).
The various fixing possibilities ensureparticular
flexibility: Your TG 125/E can be operated both
in "normal position" and in standing, with the
grinding table removed. To this end, it is fixed
with the enclosed clamp.
The grinding table is made of high-grade alu­minium and can be adjusted upwards by 10°
and downwards by 50°. This also includes the
guide slot for the angle stop that is also
included in the scope of delivery.
Twogrinding wheels in each of the grain sizes
offered of 80, 150 and 240 areincluded in the
scope of delivery.

In order that the swarf goes directly whereit
should, namely into the vacuum cleaner,thereis
aconnecting piece to which the vacuum cleaner
can be connected. So you areoptimally
equipped for the grinding work.

5Beforework

5.1 Setting up your disc grinding

machine (fig. 2):

Note:
When setting up the machine,make surethat
the ground below it is level and secure! Asecure
stand is indispensable for working with the
machine!

Note:
When setting up and fixing the machine, always
disconnect the mains plug to prevent the disc
being started up accidentally. Risk of injury!

Caution:

During all adjusting and assemblywork, such as
when adjusting the angle stop or when attach­ing or removing the grinding table, disconnect
the mains plug to prevent the device from start­ing up unintentionally!

-12-

-13-

The disc grinding machine can be operated in
two different positions: Once in the normal hori­zontal position or standing vertically (for sharp­ening tools and blades for example).
In both positions, the machine should be
securely clamped with the enclosed vice, as
shown in fig. 2.

5.2 Removing and inserting the grinding
table (fig.3):

Caution:

Before removingand inserting the grinding table,
always disconnect the mains plug to prevent the
disc being started up accidentally.Risk of injury!

Normally,your TG 125/E is operated with the
attached grinding table (as in delivery condi­tion). Additionally,thereisalso the possibility,
whererequired, of removing the grinding table,
if this is necessary for certain tasks or for
changing the grinding wheels.

Caution:

Please note that when working particularly in
the operating mode without the grinding table,
always make suretocontrol the work piece by
holding it firmly and securely in order to prevent
it from being flung about.

Use the machine in the horizontal position with
attached grinding table, if possible!

1. Remove Allen head screw 1

2. Remove the grinding table with grinding

table holder 2bypulling out from the front

3. To insert, simply push into the normal

position

4. Turn in Allen head screw 1again

Caution:

If the grinding disc is blocked due to awork
piece that is jammed between the grinding disc
and the grinding table, immediatelyshut offthe
device using the On/Offswitch and disconnect
the mains plug. Only put the device back into
operation after the jammed work piece has
been removed!

5.3 Affixing and replacing grinding
wheels (fig. 4):

Note:
Beforeaffixing or replacing the grinding wheels,
always disconnect the mains plug to prevent the
disc being started up accidentally.Risk of injury!

Twogrinding wheels in each of the grain sizes
80, 150 and 240 aresupplied as initial equip­ment with your disc grinding machine; these
can also be easily obtained as spareparts. It is
thereforenoproblem to change wheels,
whether because of wear or because discs with
various grain sizes arerequired when working.

Caution:

When replacing the wheels, it is advisable to
remove the grinding table as described in the
previous section!

1. Remove the rear protective foil above the

adhesive surface from the desired wheel,

2. Push the wheel evenly and bubble-free onto

the grinding disc.

3. To replace, simply remove the grinding wheel

again and push on the new wheel.

5.4 Adjusting the grinding table angle

(fig. 5):

Caution:

Beforeadjusting the grinding table, always dis­connect the mains plug to prevent the disc
being started up accidentally.Risk of injury!

1. Loosen rotary knob 1Atthe same hold rotary

knob 2

2. Swing grinding table 3into the desired angle

position and check the set value on angle
scale 4.

3. Tighten rotary knob 1. At the same hold

rotary knob 2

5.5 Connecting the dust exhaust
(fig. 6):

Caution:

Beforeconnecting the dust exhaust, always dis­connect 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 1onto connecting piece

2ofthe machine

2. Push rubber adapter 3onto adapter piece 1

3. Insert vacuum cleaner nozzle 4into 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 offisno
longer necessary.The CW-matic is fitted with
an automatic control device; it automatically
switches on and offwhen the power tool is
switched on and off. The same effect can be
obtained with traditional vacuum cleaners by
using our vacuum control device.

6Working with the TG 125/E disc

grinding machine

Caution:

Please note that the grinding disc turns to the
left! If you use the left side when working with
the attached grinding table, the work piece can
be guided easily and securely,thus effectively
preventing it from being hurled away!

Caution:

When grinding metallic work pieces, such as
when grinding knife blades for example, or
when grinding stone or ceramics the material to
be ground can become very hot! Do not hold
the material to be ground near the grinding sur­face in order to avoid burns!

Caution:

Wear suitable gloves to avoid abrasions espe­cially when working with coarse sandpaper and
when processing smaller work pieces!

1. If mitres aretobeground, 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)

Please adjust the size of the work piece to the
size of the machine! Awork piece that is too
large and too heavy can overburden the drive or
the construction of the machine and cause
damage or injuries!

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

If, for example, the ends of somewhat thinner
strips areground for mitre, it is advantageous to
use the angle stop included in the scope of
delivery.

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 aredifficult; 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 requirelower grinding speeds than soft
and hardwood; this also applies for ceramics
and glass.

-14-

-15-

But as stated: Recommendations aredifficult,
the correct speed depends on the material, con­tact pressureand friction and grain size of the
grinding wheels.

7Careand maintenance

Caution:

Beforecleaning, adjusting, service or repair,dis­connect the mains plug!

Note:
The machine is largely maintenance free. To
ensurealong service life, however,the machine
should be cleaned with asoft cloth, handbrush
or paintbrush after each time it is used. Avac­uum cleaner is also recommended here. Avac­uum cleaner should always be used during
work!

The outside of the housing can be cleaned with
asoft, possibly damp cloth. In this process, mild
soap or another suitable cleaning agent can be
used. Solvents or cleaning agents containing
alcohol (e.g. petrol, cleaning alcohols etc.)
should be avoided, since these can attack the
plastic cases.

8Disposal

Please do not dispose of this machine in house­hold refuse! The machine contains materials
that can be recycled. If you have any questions
about his, please contact your local recycling
company or other relevant communal facilities.
