On our deep-hole drilling machines we are able to cut almost every material (non-ferrous metals, high alloy steels and plastics)
and reach drilling depths of up to 250 x drilling diameter.
Drilling tolerances, surface finish, deviation and straightness of our deep hole drillings are
much better compared to conventional drilling processes like i.e. twist drilling.
The pre-centering of the holes is not needed because the tool is guided in a drill bush (attached to the machine).
Drill diameter 1 - 100 mm (solid drilling).
Drill depth up to 2500 mm (98.425 inches) from one side and up to 5000 mm (196.850 inches) from both sides.
centrical and eccentrical (asymmetric) drillings, if desired as well in oblique planes.
In any free cutting material up to an hardness of about 43 HRC respectively an tensile strengh of about 1300N/mm².
Workpieces up to a weight of 5.5 tons can be transported by our forklifts and gantry cranes.
On our depp-hole drilling centres we can provide additional work besides deep-hole drilling such as tapping,
reaming and 2.5D milling operations.

Turning diameter 300 - 2000 mm.
Turning height up to 1500 mm.
Additonally vertical drilling and milling operations can be implemented including driven tools.

The machining of your workpieces can be done by paper drawings, 2D- or 3D-Data.
Data can be sent by mail, contact form and in case of larger data amounts via File Transfer Protocol (FTP).3D-Data is handled by CAM Software; 2D-Data can be plotted in the formats A4 to A0 (b/w and colored).

Features that are not included in the volume model, like taps for example,
are machined according to attached color-code tables or program-based feature recognition.
