Many innovations have been incorporated in the re-engineered KASTOtec. The result is faster cutting in spite of a sawing process which reduces tool wear. Thanks to KASTOrespond, the new tec versions also detect the forces on the tool and adjust the feed accordingly.  

To improve on the tried-and-tested was KASTO’s motto when re-engineering the tec automatic bandsaws.

KASTO has comprehensively re-engineered its tec automatic bandsaws. In doing so, the designers have clearly focused on the optimum use of carbide metal saw blades. Further innovations relate to the saw feed, the main drive, and a system for automatically adjusting the feed speed.

KASTOtec has always been identified with high machining performance and low idle times. Shorter cutting times and higher saw blade service lives are possible thanks to a steel mineral casting compound. This continues to guarantee a high degree of damping and quiet running, even with difficult-to-machine materials such as titanium, Hastelloy and Inconel. In addition, standard pre-tensioned linear guides, each with two grease-lubricated guide carriages, extend the working life.

But there is much more to the new KASTOtec. New is the steplessly adjustable electromechanical saw feed with two servo motors and ball screw spindles, which now provides an ideal basis for efficient and sensitive working with reduced tool wear. The saw feed control with its minimal use of sensors enables the cutting parameters to be continuously adjusted, not only at the beginning and end of the cut but also throughout the sawing process. The user therefore benefits from maximum performance and low tool wear. The tool service life also benefits from the new double saw blade cleaning facility. A mechanical system automatically adjusts the brushes over their entire life, thus ensuring that they are always optimally positioned relative to the saw blade. This all contributes to a further increase in sawing performance.

As well as the technical improvements, the user also has control of the tool costs and cutting times. All parameters can be optimally adjusted to suit the type of saw blade used by means of the intuitive controller. Depending on the saw blade, this reduces cutting times by up to 50%.

The frequency-controlled bevel spur gear saw drive with a power of 15 kW and a steplessly adjustable cutting speed of 30 to 300 metres per minute is also new.

New for KASTOtec: KASTOrespond

The new generation includes KASTOrespond, a feature that was originally developed for KASTOwin. The system ensures that the machine is ideally set up for sawing solid material, tubes and profiles and is available for all sizes. Without additional and often error-prone sensors, the system continuously measures the forces on the tool and converts them intelligently into the optimum digital feed speed. KASTOrespond detects continuously changing engagement lengths with round material and also hard spots in solid material in good time and adjusts the feed accordingly. The user only specifies the relevant data such as cut lengths and number of pieces along with the material to be sawn. Everything else is undertaken by KASTOtec.

The new KASTOtec AC 5 saws round material up to 530 mm diameter.
