If the REMS roll grooving attachment is mounted on one of the threading
machines REMS Tornado, REMS Gigant or REMS Magnum (up to 4"),
the weight stated in the respective instructions for use is increased by
14 kg (difference between tool set and REMS roll grooving attachment).
2. Commissioning
Important: Transport weights exceeding 35 kg must be carried by two people.
2.1. Roll grooving machine Magnum 20xx RG-T
For transportation, the machine can be lifted by its guide arms (8) at the
front, and by a pipe inserted into the quick-action hammer chuck (1) and
guide chuck (2) at the rear.
Fasten the machine to the workbench or folding stand using the 2 bolts
supplied. It is essential to ensure that the machine is horizontal. Open the
quick-action hammer chuck (1). Slide the roll grooving unit onto the guide
arms (8) until the drive shaft of the roll grooving unit is projecting with its
3 faces into the quick-action hammer chuck. Close the latter until the
clamping jaws are in contact with the 3 faces of the drive shaft. With the
clamping ring (9), tighten the drive shaft after a brief opening movement
with one or two hard turns. Position and bolt the hydraulic hand pump (10).
2.2. REMS roll grooving attachment on REMS Magnum 20xx T-L
Refer to instructions for use of REMS Magnum. Swing in the pipe cutter
and the inner pipe deburrer. Undo the wing screw on the clamping ring.
Remove the oil pan with the cuttings tray. Remove the tool set. Close off
the mechanical lubricant pump by connecting the hose end detached from
the tool holder to the intake side of the pump; lubricant must circulate in-
side the pump to prevent it being damaged. Ensure without fail that the
machine is horizontal.
Slide the roll grooving unit onto the guide arms (8) until the drive shaft of
the roll grooving unit is projecting with its 3 faces into the quick-action ham-
mer chuck. Close the latter until the clamping jaws are in contact with the
3 faces of the drive shaft. With the clamping ring (9), tighten the drive shaft
after a brief opening movement with one or two hard turns. Position and
bolt the hydraulic hand pump (10).
2.3. REMS roll grooving attachment on REMS Magnum 20xx T and
REMS Magnum 40xx T
Refer to instructions for use of REMS Magnum. Swing in the pipe cutter
and the inner pipe deburrer. Undo the wing screw on the clamping ring.
Remove the tool set. Take out the cuttings tray. Place the hose end deta-
ched from the tool holder inside the coolant tray to ensure that oil can cir-
culate. In the case of machines supplied from November 1999 onwards,
a hole is provided in the coolant tray into which the hose end can be in-
serted. If required, this hole can be drilled with a 14 mm bit. Lubricant must
circulate inside the pump to prevent it being damaged. Ensure without fail
that the machine is horizontal when on a mobile stand (by removing wheels
or placing the two stand pipes underneath).
Slide the roll grooving unit onto the guide arms (8) until the drive shaft of
the roll grooving unit is projecting with its 3 faces into the quick-action ham-
mer chuck. Close the latter until the clamping jaws are in contact with the
3 faces of the drive shaft. With the clamping ring (9), tighten the drive shaft
after a brief opening movement with one or two hard turns. Position and
bolt the hydraulic hand pump (10).
2.4. REMS roll grooving attachment on REMS Tornado 20xx and
REMS Gigant 40xx
Refer to instructions for use of REMS Tornado or REMS Gigant respec-
tively. Swing in the pipe cutter and the inner pipe deburrer. Undo the wing
screw on the clamping ring. Remove the oil pan with the cuttings tray. Re-
move the tool set. Close off the mechanical lubricant pump by connecting
the hose end detached from the tool holder to the intake side of the pump;
lubricant must circulate inside the pump to prevent it being damaged. En-
sure without fail that the machine is horizontal.
Slide the roll grooving unit onto the guide arms (8) until the drive shaft of
the roll grooving unit is projecting with its 3 faces into the quick-action ham-
mer chuck. With the REMS Tornado, close the chuck by operating the
pedal switch. With the REMS Gigant, close the clamping jaws using the
chuck key until the clamping jaws are in contact with the 3 faces of the
26 kg
drive shaft. Position and bolt the hydraulic hand pump (10).

80 kg
2.5. REMS roll grooving attachment on REMS Tornado 20xx T and
80 kg
REMS Gigant 40xx T
Refer to instructions for use of REMS Tornado or REMS Gigant respec-
tively. Swing in the pipe cutter and the inner pipe deburrer. Undo the wing
screw on the clamping ring. Remove the tool set complete. Take out the
cuttings tray. Place the hose end detached from the tool holder inside the
coolant tray to ensure that oil can circulate. In the case of machines sup-
plied from November 1999 onwards, a hole is provided in the coolant tray
into which the hose end can be inserted. If required, this hole can be drilled
with a 14 mm bit. It is harmless if the electric pump runs empty, i.e. when
the coolant tray is emptied. Ensure without fail that the machine is hori-
zontal when on a mobile stand (by removing wheels or placing the two
stand pipes underneath).
Slide the roll grooving unit onto the guide arms (8) until the drive shaft of
the roll grooving unit is projecting with its 3 faces into the quick-action ham-
mer chuck. With the REMS Tornado, close the chuck by operating the
pedal switch. With the REMS Gigant, close the clamping jaws using the
chuck key until the clamping jaws are in contact with the 3 faces of the
drive shaft. Position and bolt the hydraulic hand pump (10).
2.6. Material support
Caution! Even when in short lengths, pipes must be supported using the
height-adjustable REMS Herkules or other suitable material supports
depending on their diameter (and weight!), in order to ensure that the
machine does not tip forward.
3. Operation
3.1. Tools
Three sets of grooving rollers are needed for the full working range. Each
set of grooving rollers comprises the upper pressure roller (11) and the
low counterpressure roller (13). Grooving rollers Cu (pressure roller (11),
counterpressure roller (13)) for copper tubes 54–159 mm.
Changing the grooving rollers
Operate the drive machine in inching mode using the pedal switch (4) until
the securing bolt of the counterpressure roller (13) is pointing downwards.
Undo the securing bolt and pull out the counterpressure roller (13). Turn
the pressure roller (11) until the mark on the stub shaft (12) is pointing
downwards. Undo the securing bolt and slowly pull out the stub shaft (12).
Remove the pressure roller from underneath.
Caution! Before pulling out the stub shaft (12), place your hand under-
neath the pressure roller (11) – otherwise it will fall onto the floor!
Insert the selected pressure roller from underneath and slide in the stub
shaft (12). The mark on the latter must be pointing downwards. Tighten
the securing bolt of the pressure roller in the direction of the shaft mark.
Insert the selected counterpressure roller. Note the position of the drive
dog (flat edge) on the rear end of the counterpressure roller. Tighten the
securing bolt.
3.2. Working procedure
Pipe ends must be cut off at right angles. Welds or welding residues (beads)
in the pipe must be sanded off over a length of some 50 mm from the pipe
end. Clean any dirt and scale off the inside and outside of the pipe ends.
Close the pressure limiting valve (16). Place the pipe on the counter-
pressure roller and press it against the machine. Align the pipe axis-pa-
rallel, supporting it as necessary. Operate the feed lever (15) of the hy-
draulic hand pump several times and feed the pressure roller (11) forward
until it is up against the pipe. Set the stop for the groove depth (17); to do
so, turn the setting disc for groove depth (18) to a stage corresponding to
the pipe size between the housing and the stop plate, and move the stop
inwards until it is up against the setting disc. Secure the stop plate using
a locking nut. Turn the setting disc back to the engagement position so
that the stop plate can be moved downwards. Operate the machine at top
speed. Switch on the machine using the pedal switch (4), operate the feed
lever (15) several times, and slowly slide the pressure roller (11) into the
pipe while the machine is running until the stop plate is touching the hou-
sing (pressure on feed lever increases). Keep the machine running a few
more turns without feed. Then shut down the machine, open the pressure
