New bandsaw for cutting metal tube KASTO has introduced a new bandsaw specifically for cutting tubular material called KASTOwin tube A 5.0.

comprehensive material database, is able to set all sawing parameters automatically for nearly all types and cross sections of material. In addition, a new KASTOrespond feature 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, as tubes in particular present a blade with widely varying conditions throughout the cut, especially at material breakthrough. It is, however, also applicable to cutting all types of stock. The tube saw boasts all of the benefits that characterise other units in the German-built KASTOwin series.

The blade cuts from the bottom up- wards – the reverse of the action on other bandsaws. It reduces wear on the band and avoids damage to its teeth that often occurs when a blade travels downwards into swarf that has accumu- lated inside the bottom of the tube. Until now, this problem made it virtually impossible to use a tungsten carbide tipped 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. The automatic saw has a feed mechanism rotated through 180 degrees so that the cutting action starts at the surface supporting the stock. Capacity is 500mm diameter for round tube and the shortest cutting length is 10mm. The frequency-controlled drive

can be adjusted steplessly to deliver a cutting speed between 12 and 150m per minute. The upfeed is equipped with zero- play linear guides, while ballscrews ensure controlled cutting and material infeed. The saw band is clamped in position hydraulically for cleaning by a replaceable, electrically driven chip removal brush. The intelligent SmartControl ensures easy operation and, as it contains a

CNC pipe finishing machine

Our CNC controlled pipe finishing machine is capable of internally and externally machine the pipe. It can do beveling, squaring, deburring, tapering, counter boring and threading. The machine uses a cutting bit to prepare all angles and shapes. With the radial and axial feeding in combination with the CNC system it offers all the pre-set shapes that are implemented in the software. Even thick wall pipes and stainless, duplex, Super duplex material can be easily machined with our CNC machine. Contact us for your inquiry. We offer machinery up to 48” and we offer custom made solutions.
