 Tubes and cylinders

|
|
In our programme you can find glass tubes and cylinders in different glass qualities - whether as a
whole length or readily cut into sections, including edge treatment. We produce tubes and cylinders
according to your needs and with nearly all lengths between 1 - 2,000 mm. |
| |
We process the following glass qualities; further qualities can be supplied on request.
It is also possible to bring your own glasses for processing. |

Precision glass tubes and cylinders
|
|
|
|
|
|
|
|
| Further we also manufacture precision glass tubes and cylinders. With calibrated inside diameters and round-polished surfaces also technically polishes are available... |
| |
|
As a speciality we offer glass tubes and cylinders that are calibrated inside.These tubes and cylinders
are trimmed to their exact measures and the shape desired by using an internal tool.
The shape need not necessarily be round but can also be square or conical, for instance.
The tubes can also be calibrated outside by grinding them round. In this case, the grinding
will make the surface look mat, but by "technical polishing" afterwards, the surface can be refined. |

ready-made...

|
|
|
|
|
|
| The cutting-up of the tubes can be done the following ways; the character of the sections corresponds to the method used. |
|
|
|
|
Carving and breaking
|
|
|
|
| |
Sharp-edged, not 100 % plane, the cutting area is glass clear |
|
|
|
|
Thermal shock method
|
|
|
|
| |
Sharp-edged, not 100 % plane, the cutting area is glass clear |
|
|
|
|
Sawing
|
|
|
|
| |
Blunt, not 100 % plane parallel, section is mat, edges may have small raptures |
|
|
|
|
Parting-off
|
|
|
|
| |
Blunt, plane parallel cut, section is mat, to a great extend without raptures |
|
|
|
|
|
Further manufacturing operations are possible...
|
|
|
|
|
|
|
|
| After cutting them into lengths, tubes can be reprocessed. We offer, for instance, the following treatments |
|
|
ㆍ
|
Rounding or fire-polishing the edges |
|
ㆍ
|
Chamfering the inner and outer edges |
|
ㆍ
|
Matting the surface ( sandblasting ) |
|
ㆍ
|
Thermal shaping of the ends |
|
ㆍ
|
Drilling or extending the cylinder ends |
