Tangential Rolling Systems
Tangential rolling systems
Threads of the highest surface quality can be produced with minimum machining times using the Wagner tangential rolling system.
The tangential rolling tool is mounted with the adapter on the tool carrier, e.g. turret disc. It moves with a constant feed onto the rotating workpiece. The thread rolls are set in rotation by touching the workpiece and form the thread as the tool carrier continues to feed. As soon as the thread rolls have reached the centre of the workpiece the rapid return is initiated and the workpiece is released. Optimum productivity is achieved using precise thread rolls with maximum tool life. The diameter, pitch and shape of the rolls are adapted to the thread to be rolled. Wagner tangential rolling tools are available in various sizes and are suitable for machining workpieces from Ø 1.6–52 mm.
Premium rolling results in fine-pitch threads can be achieved by using our tool variant “F”. For threads with very small pitches, it is important to keep the axial play of the thread rolls as low as possible. By means of the patented Wagner axial play fine adjustment, the axial roll play can be minimized in 0.02 mm steps. The fine adjustment is available as an option.
Profile rolls for special applications such as rolls for lubrication grooves, knurling or smoothing are also available.
AREAS OF APPLICATION
- cylindrical and conical threads, right- and left-hand threads as well as regular and fine threads
- threads behind a collar
- threads close up to a collar
- very short threads
- threads where the end of the workpiece is not free
- threads with very short run-outs
ADVANTAGES
- very short processing time
- large operating range
- long tool life due to large rolls and high rigidity of the tool body
- particularly low-maintenance
- the rolled threads are suitable for high loads due to their uninterrupted fibre course direction.
- durable, wear-resistant and corrosion resistant threads
- high flexibility due to numerous adapter variants for use on different machines, e.g. single and multispindle lathes as well as special machines
STANDARD TYPE

TANGENTIAL SYSTEMS WITH FRONT MOUNTED ROLLS
Front mounted rolls make it possible to roll threads directly up to a collar or chuck.
ADVANTAGES
- Working range M3–M42 / UN5–40 to UN 1 5/8″
- Problem solver for demanding workpiece geometries and special workpiece clampings
- For highest thread quality
- Process reliability due to high performance thread rolls
- Simple operation and quick roll change
- Shortest machining times
- Ideal e.g. for stainless steel fittings

DESIGN WITH FRONT MOUNTED ROLLS
Tangential rolling tools with front mounted rolls are available exclusively from Wagner. Within the shortest machining times, it is possible to roll threads directly up to the collar or the chuck. These tools are designed for use on all common lathes with a controlled feed motion.
TYPE VARIANT F
Quick and easy adjustment of the AXIAL ROLL PLAY for best thread quality and long tool life for Type “F”. Especially recommended for fine threads.

ROLl FORM AND SELECTION CRITERIA
Depending on the application, different types of thread rolls can be used. The roll form DR is not possible for all threads and must be clarified for each individual case.
DIMENSIONS OF THE THREAD ROLLS
The dimensions for the individual shapes of the thread rolls can be taken from the following table:
| Typ | A | B1 | B2 | B3 | d1 | d2 |
|---|---|---|---|---|---|---|
| B8 | 14,7 mm | 12,2 mm | 10,8 mm | 14,2 mm | 12,9 mm | 14,4 mm |
| B10 | 19,8 mm | 15,8 mm | 13,2 mm | 19,3 mm | 14,9 mm | 17,1 mm |
| B13–B16 | 26,25 mm | 22,6 mm | 19,7 mm | 25,75 mm | 20,1 mm | 21,8 mm |
| B19 | 35 mm | 31,2 mm | 28,5 mm | 34,5 mm | 23,3 mm | 25,2 mm |
THREAD RUN-OUT, THREAD UNDERCUT
The thread rolls are chamfered at an angle α. For workpieces without undercut, the angle α = 30° should be used. Angle α = 45° or 60° is used when the last full thread of the workpiece must be very close to a collar and only for workpieces with undercut.
S = Sicherheitsabstand (min. 0,3 mm)
L = erforderlicher Gewindeauslauf ( = Z + S)
M = erforderlicher Überstand der Gewinderolle in den Freistich
O = erforderliche Breite des Gewindefreistichs (= M + S)
Die Gewinderollen und der Bund des Werkstückes dürfen sich nicht berühren, d.h. es muss ein Sicherheitsabstand vorgesehen werden. In den Abbildungen sind die erforderlichen Abstände dargestellt.
α = angle of the chamfer on the thread roll
Z = width of the chamfer
T = depth of the thread profile
The thread rolls and the collar of the workpiece must not touch each other, i.e. a safety distance must be provided. The required distances are shown in the illustrations.
