Delivery programme for feeding units and drawing benches

Drills that penetrate deeper THE successful Walter Xtra.tec four-edged Insert Drill range has been expanded to include sizes from 16.5mm to 35mm diameter with depth to diameter ratios of two to five. Due to the balanced positioning of the indexable inserts and combined with the wiper function, in addition to higher surface quality of holes produced, the inherent rigidity and stability of the design has been acclaimed for the ability to spot drill from solid – and can even be applied directly to crowned surfaces. The Insert Drill is available in two geometry variants for medium demand machining conditions as a universal tool with a rake angle of 13°. The E57 tool is ideal for cast iron, steel and corrosion resistant materials. For more difficult conditions when cutting cast iron and steel, the A57 has been introduced with a rake angle of 0°.

THE delivery programme of sema Systemtechnik includes feeding units, drawing benches, straightening machines, sawing units and testing lines, and also packaging machines for tubes and profiles. The packaging units are designed for bars andtubeswithadiameterrangefrom5-200mm and for profiles (hex, square, etc) from 8-50mm. Also hot-rolled profiles and U-, IPB and special profiles can be packed. Mostly the round materials are packed to hexagonal shaped bundles. Hexagonal and square profiles are packed to square bundles, where hexagonal materials are packed on the edges. All other profiles can be packed nested depending on their cross section. Therefore these materials are automatically turned during the transport to the stacking station. After stacking the finished bundle is transported across out of the stacking station. The stacking station can start stacking the next bundle immediately. The bundles can optionally be strapped manually or automatically. By

using automatic operation the bundles are transported longitudinally. During the longitudinal transport the bundle can be wrapped with foil at the positions where the bundle has to be strapped with steel belt. The strapping positions are pre-selectable at the operating desk. In other packaging combinations it is also possible to strap the bundles with plastic belt. Weighing devices can be integrated into the sema packaging machines. Futhermore, sema Systemtechnik manu- factures packaging machines for the copper tube industry. These machines are often small bundling machines where 5-20 tubes are collected into small bundles and are wrapped with adhesive tape. These small bundles are then gathered into large bundles which can also be strapped. sema Systemtechnik Sewing GmbH & Co KG – Germany Email: a.burkamp@sema-systemtechnik.de Website: www.sema-systemtechnik.de
