4. The pipe machining process
begins with the cutting of the
ends, where we incorporate
fully automated lines with
two Danobat CP sawing
machines that can move
along a slide in order to adjust
pipe length according to your
specifications.

5. Pipe ends are threaded by rotating the pipe in our Danobat TT model lathes.
These machines are designed with a modular concept utilizing Finite Element
Analysis. The main features are as follows:
? 4 axes simultaneous threading, reducing cycle time.
? Symmetrical versions available, ie. headstock either on the left or right
side, adapting to your plant flow and or floor plan.
? Headstocks prepared for assembly of front and rear chucks, either
pneumatic or hydraulic. Integrated into headstock front hydraulic 6 jaws
(3 compensating, 3 centering) chucks are also available.
? Main motor power up to 170 kW (230 Hp), depending on model.
? Pipe stopper, optionally with centering features.
? Chatter reducing internal support automatically retractable.
Patent pending.
? Tooling solutions for external threads, coupled connections, or internal
threads and integral connections.
? Available with Fanuc, Siemens or Fagor CNC.
Different designs of pipe feeding tables may also be integrated along with the
lathes for a single source turnkey solution.

6. COUPLING MACHINING
The coupling machining process begins with cutting.
DANOBATGROUP can provide high production saw
cutting with the Danobat CP range of saws. Powerful
software optimizes machining process, it integrates
adaptative intelligent cutting and blade deflection
control that adjusts automatically the blade speed and
downfeed to obtain optimal performance, straigtheness
of the cut, and blade life.
The coupling cut can be integrated in a fully automatic
line where in addition to the cutting, OD machining
and ID roughing are performed on the TCL range of
Danobat lathes. This model is a 4 axes machine where
OD and ID machining is performed simultaneously,
prior to the cut off of the coupling. The handling is
fully automated. With the addition of a welding robot
a continious flow is created, welding the last piece of
machined pipe with a new one.
The machining line may be completed with a threading
lathe, either a CL or a CIH machine model. This provides
a coupling production line from pipe till threading,
finishing completely all coupling machining in a fully
automatically integrated line. You may machine
PREMIUM couplings up to 13 5/8¡± in diameter.

8. Coupling threading may be done in a single clamping on the CIH range of machines,
or in two set ups on the CL range. Main features as follows:
? Rigid design capable of performing not ? Main motor power up to 100 kW, (134

Different designs of coupling handling systems may also be integrated along with the
lathes for single source delivery on a turnkey basis.
