Changing the chuck jaws
With the clamping ring (22), close the chuck jaws (24) to a clamping diameter
of approx. 30 mm. Remove screws of chuck jaws (24). Slide chuck jaws out
towards the rear by using an appropriate tool (screw driver). Slide new chuck
jaws into the chuck jaw carrier from the front.
3.3. Operation
Remove blockages of chips and fragments of the workpiece before starting
work.
Swing out the tools and move the tool carrier to the right-hand end position
with the aid of the pressing lever (8). Pass the material to be threaded through
the opened guide (2) and through the opened chuck (1) so that it extends by
about 10 cm from the chuck. Close the chuck until the jaw comes against the
material and then, after a short opening movement, jerk it shut once or twice
in order to clamp the material firmly. Closing the guide chuck (2) centers the
material that extends from the rear of the machine. Swing down and close the
die head. Set the switch (3) to position 1, then operate the foot switch (4). Type
U is switched on and off with the foot switch (4) only.
On Type K and Type D, the second operating speed can be selected for
sectioning, deburring and small thread cutting operations. To do this, with the
machine running, slowly move switch (3) from position 1 to position 2. With the
contact lever (8), advance the die head onto the rotating material.
After one or two threads have been cut, the die head will continue to cut auto-
matically. In the case of tapered pipe threads, the die head opens automatically
when the standard length of thread is reached. When cutting extended threads
or bolt threads, open the die head manually, with the machine running. Release
pedal switch (4). Open quick action hammer chuck, take out material.
Threads of unlimited length can be cut by reclamping the material, as follows.
When the tool holder approaches the machine housing during the thread cutting
process, release pedal switch (4) but do not open the die head. Release the
material and bring the tool holder and material to the right-hand end-position
by means of the contact lever. Clamp material again, switch on machine again.
For pipe cutting operations, swing in the pipe cutter (18) and bring it to the
desired cutting position by means of the contact lever. The pipe is cut by rotating
the spindle clockwise.
Remove any burrs inside the pipe resulting from the cutting operation with the
pipe reamer (19).
To drain the cooling lubricant: Take off the flexible hose of the tool holder (7)
and hold it into a container. Keep the machine running until the oil tray is empty.
Or: Remove screw plug (25) and drain trough.
3.4. Production of nipples and double nipples
Use ROLLER'S Spannfix (automatic internal clamping) or ROLLER'S Nipparo
(internal clamping) for threading nipples. Ensure that both sides of the pipe are
deburred inside. Always slide the pipe up to the end of the clamping section.
To clamp the piece of pipe (with or without thread) with the ROLLER'S Nipparo,
use a screwdriver and turn the spindle to expand the head of the Nippelspanner.
Expand only with attached piece of pipe, otherwise damage will arise.
Do not cut nipples with ROLLER'S Spannfix and ROLLER'S Nipparo shorter
than is permitted by the appropriate standard.
3.5. Producing left-handed threads
For left-handed threads only the ROLLER'S Robot 2K, 2D, 3K, 3D, 4K and 4D
are suitable. The die head in the tool set holder has to be off-set e.g. by using
a M 10 x 40 screw in order to cut left-handed threads, otherwise the lifting and
the start-cutting can be damaged. Set the switch to position "R". Change the
hose connections at the coolant pump or for shut of the coolant pump briefly.
Alternatively use a switch valve (Art.No. 342080, accessory), attached to the
machine. With the lever on the switch valve (Fig. 3) the direction of flow on the
coolant pump is reversed.
4. Maintenance
DANGER
Pull out the mains plug before maintenance and repair work! This work
may only be performed by qualified personnel.
4.1. Maintenance
The machine is maintenance free. The gearbox operates in a sealed-off oilbath
and therefore needs no lubrication.
4.2. Inspection / Servicing
The motor of the Type U is equipped with carbon brushes. These wear out and
therefore need checking from time to time, and, if necessary, changing. Loosen
by about 3 mm (⅛") the 4 screws of the motor cap and remove both caps from
the motor. See also point 6: Actions in case of trouble.
5. Machine Wiring and Electrical Components
See next page.
6. Actions in case of trouble
6.1. Trouble: Machine does not start.
Cause:
● Emergency switch not unlocked.
● Protective motor switch engaged.
● Worn out or faulty brushes (Type U).
6.2. Trouble: Machine does not pull through.
Cause:
● Dies are blunt.
● Poor-quality cooling lubricant.
● Circuit overloaded.
● Wire cross-section of extension cord too small (min. 2,5 mm²).
● Bad contacts at the plug connections.
● Worn out brushes (Type U).
6.3. Trouble: Low or non-existent oil supply at die head.
Cause:
● Pump defective.
● Insufficient cooling lubricant in the oil tray.
● Strainer in intake clogged.
6.4. Trouble: Dies too far open in spite of correct scale setting.
Cause:
● Die head not closed.
6.5. Trouble: Die head does not open.
Cause:
● Thread was cut to the next pipe diameter up with die head opened.
● Length stop folded away.
6.6. Trouble: No workable thread.
Cause:
● Dies are blunt.
● Dies are wrongly positioned: see numbers.
● Low or non-existent oil supply.
● Poor-quality cooling lubricant.
● Feed movement of tool holder hindered.
6.7. Trouble: Pipe slips in the chucks.
Cause:
● Clamping jaws very dirty.
● Use special chucking jaws for pipes with thick plastic sheathing.
● Clamping jaws worn.
7. Disposal
The machines may not be thrown into the domestic waste at the end of use.
They must be disposed of properly by law.
