Deep hole drilling machines made in Germany

ELB - machines

Deep Hole Drilling Units are used chiefly in special machine building, in transfer lines, or with a separate base, as an independently-operating single machine. The main area of application lies in the automobile and commercial motor vehicle industry with their vendors. Likewise, the aviation technology, medical technology and, more and more, the general mechanical engineering, invests into highly precise low drill machines. The gun-drilling system is used here. The units are manufactured with 1-,2-,3-,4-, or 6-spindles, since the compact design, combined with an ingenious module system, has proved to be extremely reliable.

BTA - machines

Deep Hole Drilling Machines are now used profitably in nearly all areas of machine building, metallurgical engineering and semi-finished product manufacturing. Medium and heavy machines are mainly built with 1 spindle. The BTA drilling system is generally used herein. For difficult spot-drilling or sealing situations, the ejector system (dual tube system) is used. By means of an ingenious module system, a change can be carried out in best time from one system to another or between the different drilling diameters or workpiece clamping applications.

Cylinder processing machines

Cylinder Processing Machines are inserted today primarily in the hydraulic manufacturing, as well as in spraying mechanical engineering. Likewise, the possibility exists to use the machines with appropriate equipment also for the chamberboring of inner contours. Beyond that, the skiving and roller burnishing (tumble) used here, gains even in general mechanical engineering more and more significance. For example, construction units with high surface quality which require at the same time a high standard of firmness by solidification of the workpiece surface.

Coordinate-deep hole
drilling machines

Coordinate Deep Hole Drilling Machines are used chiefly in mould-, die- and tool-making, as well as for singlepart and mass production. Depending on the application, gun drilling tools are used for deep hole drilling work, and also BTA tools in special cases.

Deep Hole Drilling Plants

For a more complex process with an complete automated production, we recommend our Deep Hole Drilling Plants. Deep Hole Drilling Plants are mainly found in the automobile industry for high quantities, and its suppliers. The BTA-, as well as the gun drilling system is used here. The units are manufactured with 1-, 2-, 3-, or 6-spindles, since the compact design combined with an ingenious module system has proved to be extremely reliable.

Production system:

ELB / BTA

02

additional processing possible:

for example: Counter-drilling, honing, threading, deburring and bottle boring
