UK launch of new KASTO bandsaw for cutting tube

On stand 4638 at MACH 2016, KASTO will show for the first time in the UK a new, automatic bandsaw, called KASTOwin tube A 5.0, designed specifically for processing tubular material up to 530mm diameter. The blade cuts from the bottom upwards, unlike on other bandsaws where the reverse is the case. The novel action reduces wear on the band and avoids damage to its teeth that often occurs when a blade travels downwards into swarf that has accumulated inside the bottom of a tube.

Until now, this problem made it virtually impossible to use a high efficiency, tungsten carbide tipped (TCT) blade for sawing tube, as the delicate teeth were invariably damaged. A bimetal blade was the only option. This is a thing of the past with the KASTOwin tube A 5.0, on which TCT blades may be used without fear of premature wear, resulting in greatly increased productivity.

The intelligent SmartControl ensures easy operation and incorporates a new KASTOrespond feature that continuously records the force on the tool, without the need for additional sensor systems that are often fault-prone.

An intelligent algorithm continually varies the feed rate so that the force on the blade is maintained at a constant, optimised value. The feature was developed for the KASTOwin tube A 5.0 but is applicable to cutting all types of stock.

KASTOwin bandsaws are innovative and cost-effective

The tube saw is the sixth model to be introduced to the KASTOwin range of bandsaws. The original five fullyautomated bandsaws have maximum cutting capacities from 330 to 1,060mm and are suitable for processing a variety of materials, especially steels, in stockholding and manufacturing. A KASTOwin 3.3 with a maximum cutting capacity of 330 mm diameter or 330mm x 350mm will be demonstrated at the show, equipped with a hydraulic layer clamping device.

The various sizes of saw are similarly constructed and the components used are largely identical.

Moreover, 25 per cent fewer parts are used in each machine compared with their predecessors, so KASTO is able to offer the saws at considerably lower prices than comparable products.

Nevertheless, quality remains high. The bandsaws feature a frequencycontrolled drive that enables cutting speeds of 12 to 150 metres per minute.

For all machine sizes, the saw band is hydraulically tightened and looped around hydraulic band guides, which now have interchangeable carbide inserts. The latter save 80 per cent of the previous cost of replacing an entire carbide guide.

To reduce idle times, an innovative feature called KASTOsense eliminates the need for a 5 mm stand-off from the material surface. Instead, the saw blade descends straight into the material and stops within microseconds to continue the cut at the programmed infeed rate, without damaging the teeth.
