Deep Hole Drilling Machine TB1

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.

Deep hole drilling machine TB1 / TB2

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 BTA- or Gun Drilling system is used here. The units are manufactured with 1-,2-,3-, or 4-spindles, since the compact design combined with an ingenious module system has proved to be extremely reliable.

Deep hole drilling machine TB2/TB4

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 machine

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 chamber- boring 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. Cylinder Processing Machines can be used beside the usual drilling out skiving and roller burnishing opera- tions also for full boring, depending on installed achievement and equipment. Here, fast re-equip ping particularly becomes effective by a sensible building block principle, so that secondary times are reduced to a minimum. For drilling and/or peeling and smooth rolling mill tool, all commer- cial tools can be used.

Co-ordinate deep hole drilling machine

Co-ordinate 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. By the use of a special tool-carrier with steep taper seating, it is possible to produce all conventional processes such as spot-facing, thread-cutting, milling, etc., in addition to deep hole drilling. It is thus possible to carry out even complicated sequences of operations on one workpiece in one clamping.

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.
