cost solution. Even if others would give away conventional sawing machines for free, the potential operating savings offered by the Linsinger Multi-Cut prove to be more attractive. Multi-Cut technology is not only cheap to operate, but also well proven, having been derived from flying tube cut-off know-how.” Linsinger Maschinenbau GmbH – Austria Fax: +43 7613 8840 951 Email: maschinenbau@linsinger.com Website: www.linsinger.com

LINSINGER Multi-Cut features three small diameter circular saws mounted on a rotating frame. The tube is positioned and clamped and the three circular saws cut into the tube while the frame rotates 120°. The very short cycle times enhance the output performance of state-of-the-art tube mills. The robustly designed control system allows independent operation of each saw blade, and enables uninterrupted production, even in the event of partial tool breakage. This feature reduces unplanned stoppages by automatically allowing production to continue without interruption with two saw blades and the frame rotating 240°. The lifetime renewal cost of conventional large diameter blades is many times higher than the initial machine investment. The potential savings offered by the smaller Linsinger Multi-Cut blades far outweigh the additional machine investment. For example, for tube diameter range 150– 660mm, the renewal cost of a Multi-Cut blade is up to 15 times lower than the renewal cost of a conventional large diameter blade.

The smaller blade diameter with higher blade stiffness used by the Linsinger Multi- Cut MC3 offers the bonus of significantly improved blade life. The resulting additional savings in running cost reduce the pay-back period to two to three years over conventional large blade sawing machines. As Hans Knoll, Linsinger CEO commented: “The Multi-Cut is a very low

Combination for thread generation TOOLING giant Walter GB is offering the twin force combination of Titex drilling and Prototyp tapping as a tooling package for high-performance yet cost-effective thread generation.

Prototyp ECO-HT tap – a universal HSS- E-PM tap with THL coating and innovative surface treatment, capable of operation at three times diameter for use in both short and long chipping materials, and offering high-integrity process reliability without bird nesting and with long tool life even at maximum cutting speeds; Prototex ECO- HT – with spiral point form for through-hole thread generation; Paradur ECO-HT – with R45 helix angle, chamfer form C, bevelled thread run-out and long flutes for blind hole threading. Walter GB is providing the ‘off-the-shelf’ kits for blind and through-holes – each equipped with a Titex X-Treme Plus drill and two Prototyp taps – in a range of sizes

Modular Machine Tools

The Walter Titex X-Treme Plus drill provides effective machining of up to five times diameter on steel, cast iron, stainless and non-ferrous materials courtesy of an internal coolant supply coupled with Walter Titex’s innovative double performance line (DPL) double coating. Comprising a basic coating to protect the tool and to optimise the adhesion of the special tip coating, the innovative DPL technology enables the tool to operate at greater cutting speeds than usual while offering extended tool life at conventional cutting parameters. Complemented by any one of three Walter Prototyp taps, the result is maximum thread generation efficiency. The trio is:
