SOLUTIONS FOR AUTOMOTIVE

T-DRILL offers full range of fabrication solutions

for your tube forming and cutting applications for

automotive industry.

S54

The T-DRILL collaring method enables reliable

and easy T-joining of tubes. It is cost-effective

solution for fluid carrying systems being used

in heating, cooling and power steering tubing.

TCC  Series

The T-DRILL chipless rotary tube Cut-Off systems provides a

highly automated, fast and accurate method for cutting small

diameter tubes to length from coils or straight lengths. In-line

Endformers are available for all common end forms in copper,

aluminum and steel.

IT’S THE TOOLS

Measuring 3D

bent profiles

PROFILES have become more important for the industry in

recent years. Architecture and design offices, engineers and

engine manufacturers work on many different variations of

innovative profile techniques, and solutions for process optimised

bending tests are daily tasks. TeZetCAD from TeZet is able to

measure not only freeform bent round tubes but also freeform

bent profiles.

Profiles are more versatile than tubes, and provide more

opportunities in applications and more operational rigidity,

referring to machining and design projects, than the traditional

round tube.

Supplementary functions can be integrated into a profile, for

example supporting surfaces or screw-on parts, sealing or joining

functions, or locating surfaces as formclosures.Three-dimensional

transformation acts as an additional challenge. Possibilities and

applications are so widely spread that the follow up of their

realisation into production is not straightforward. Advanced

engineering of the automotive, aviation, aeronautics and nautical

industries, amongst others, collaborate with different national

and international universities and research and development

companies, to be able to assure a smooth bending production.

The three-dimensional transformation of freeform bent profiles is

more complex than that of tubes. A tube has a round cross-section,

and may get a light ovality because of the deformation, but in the

end the centreline stays the same. Non-circular profiles are as

different as the applications for which they are designed. They may

be symmetric or asymmetric, may have only one chamber (square,

rectangle, hexagon) or multiple chambers. The deformation of the

profile outlines and the cross-sections of asymmetric chambers

may change more than those of a round tube.

In TeZetCAD, freeform bent profiles are measured in a tactile

manner, and not with a laser as freeform bent tubes. If the user

has long profiles and ‘loses its way’ with the tactile probe on the

material, he can go back or just start a replay measurement of

the lost path, without interruption of the whole measurement.

The established method of leap-frogging – if the parts are longer

than the workspace of the measuring device – is possible without

losing the coordinate system and without interruption of the

measurement.
