Intended use of the machine.
The GXC cylindrical grinding device is intended exclu-
sively for grinding and polishing of steel pipes, light metal
pipes as well as for solid round steel bars with diameters
ranging between D = 10 - 100 mm.
The GXW coolant unit is intended for cooling of the
work piece.
Mounting instructions (Figure 1 + 2 + 3).
Belt grinder GX75.
Before any work on the machine itself, pull the power
plug from the socket outlet.
Dismount the spark guard (3).
Dismount the grinding rest (5), the dust collector (6)
and the star knob bolt (4).
Open the side cover (8).
Loosen the belt tension lever (1) and remove the
grinding belt.
Close the side cover.
Loosen the lever for the swivel device (7) and posi-
tion the belt grinder approx. level.
Cylindrical grinding module GXC.
Take the module out of the packaging and mount the
accessories as described in the data sheet.
Position the cylindrical grinding device against the
belt grinder and align the drill holes (33).
Connect both units with the two lever and the bolts
with wing nuts (9).
Tilt the machine to a light forward position.
Clamp the lever for the swivel device (7).
Loosen the four star-knob bolts (10) underneath the
basin (Fig. 2) and align the bottom of the GXC to the
floor.
Fasten the four star-knob bolts (10) underneath the
basin (Fig. 2).
An qualified electrician must connect the loose cable
to the power point in the GX 75 switch according to
wiring diagramm (see appendix).
Coolant unit GXW (Figure 3 + 4 )
Position the tank on the base plate of the cylindrical
grinding device.
Fill up the coolant tank with approx. 10 – 15 litres of
coolant.
Place the lid with the pump unit onto the tank and
mount the return hose to the connection sleeve of
the basin (14).
Mount the coolant hose (27) to the cylindrical grind-
ing device with the holder (29) in the threaded hole
(34).
The coolant hose must be mounted in such a manner
that the brake wheel or work piece cannot catch hold
of it.
Plug the plug of the coolant unit into socket
outlet (21).
Mounting/replacing the grinding belt.
Before any work on the machine itself, pull the power
plug from the socket outlet.
Release the belt tension lever (1).
Mount a grinding belt, size 75 x 2000 mm.
The direction-of-rotation mark of the grinding belt
must correspond with the direction of rotation.
Tension the grinding belt with the belt tension
lever (1).
Move the sanding belt manually and observe, if it
moves off towards the left or right of the contact
roller.
Adjust the guidance of the drive wheel on the belt
grinder in such a manner that the grinding belt runs
centred. The exact adjustment is made with the
machine running.
Switch the belt grinder on. Check if the contact pul-
ley rotates in the direction of the arrow.
Switch the belt grinder off again.
When the contact pulley is turning in the opposite
direction of the arrow, then the rotation direction of
the motor must be changed by a qualified electrician.
Adjusting the guide rail (Figure 3A + 5)
Before any work on the machine itself, pull the power
plug from the socket outlet.
Loosen both bolts (26) and adjust the clearance of
the guide rail to the brake wheel:
– Pipe diameter 10 - 12 mm: Adjustment according to
Figure .
– Pipe diameter 12 - 100 mm: Adjustment according to
Figure .
Tighten both bolts (26) again.
Adjusting the brake wheel (Figure 3)
Before any work on the machine itself, pull the power
plug from the socket outlet.
Adjusting the parallelism
Release clamping Star-knob (12) and adjust the
brake wheel (17) with the handle (13) in such a man-
ner that it runs parallel to the contact pulley when
viewed from above. With this measure, a uniform
feed pressure and grinding pattern are achieved. The
optimal setting must be determined by practical test-
ing.
