Tube machining

Accessory processing of tubes, section bars and tubular elements in metal

Bent or roll bent metal tubes, section bars and tubular elements can also be marked, drilled and flattened.


Marking of tubes or tubular elements serves to identify them thanks to the application of special data such as the product code, the production lot, the date or any other information that can serve to trace the tube.

The marking done by Tecnocurve may include:

  • Mechanical marking
  • Laser marking

In both cases, it is used by the client to trace the bent tubes supplied.
Laser marking is done with the laser tube; it is rapid and highly customizable. Mechanical marking is done manually in a longer process that, however, offers the advantage of remaining visible even after surface treatments.


Flattening is mainly done on round tubes and serves to deform the end of the bent tube by pressing the ends together and flattening them.

Automotive systems and ski lifts are the main sectors that use this service.


We design and produce special dies that are then installed on hydraulic presses capable of completing the processing on the bent tube.


We can combine processing with the laser tube and flattening so as to obtain more rapid accessory transformations that would otherwise be done later (drilling or slotting).


Drilling is a process that, as the name suggests, enables us to drill holes of various sizes and shapes in tubes, tubular elements and section bars in steel, stainless steel and aluminum.

We can drill many different types of holes, both with the laser tube before cold bending and after bending with work centers or specific semi-automatic drilling machines.


We produce normal holes, tapered holes, counterbored or threaded holes.


At times, to optimize the process, it is possible to perform these operations during the bending or roll bending cycle, once again reducing to a minimum the total time necessary for completion of the work.

Our tube processing methods

The accessory processes are done in our workshops only when combined with our other services.

Laser tube and pipe cutting

Thanks to our two modern laser tubes we are able to produce tapered, square and hexagonal holes, slots, tube-end facing, mitre cuts and marking

Roll bending tubes

We are specialized in roll bending steel, stainless steel and aluminum tubes, section bars and tubular elements. Types of tubes and cross sections At

Tube milling

With our two work centers, here at Tecnocurve we are able to satisfy our clients even with those additional processes that require extreme precision

Lathing metal tubes

Lathing on tubes and solid round bars that can be bent or become parts of welded assemblies. Types of tubes and relative cross sections

Pipe and tube welding

We perform MIG-MAG and TIG welding of tubes, section bars and tubular elements in steel and stainless steel, employing qualified personnel in accordance with
