German metal sawing and storage equipment manufacturer, KASTO, has introduced a new, high performance, economically priced bandsaw, called KASTOwin pro AC 5.6, said to offer short cutting times, long blade life and intuitive operation. Availability in the UK and Ireland is through the company’s Milton Keynes subsidiary.

The automatic machine is optimised to extract the best possible performance from either a bimetal or tungsten carbide tipped (TCT) blade. It is ideally suited to a wide range of applications cutting solid material, tubes and profiles, particularly in steel production and stockholding, machine manufacturing and the automotive industry.

The bandsaw can significantly increase production speed and efficiency. Depending on the type of blade and the material being cut, processing times can routinely be reduced by up to 50 percent and more in some instances.

An important feature of the KASTOwin pro AC 5.6 is its innovative, electromechanical downfeed. It is controlled via two ballscrews, each with a servo drive, for precise, infinitely variable control. There is a retraction unit for separating the blade from the material to protect the cut surface when the saw head moves back. It also helps to minimise tool wear.

The drive unit and sensor are separate from the working area, ensuring reliable, trouble-free operation. Access to the machine is good, despite compliance with CE safety standards.

The saw band is driven by an 11 kW, frequency-controlled motor, delivering infinitely adjustable cutting speeds from 12 to 150 m/min and providing plenty of capacity for TCT sawing. Helping to dampen vibration are ‘Trum’ guides mounted at the return side of the blade, inside the top of the saw head guarding. They suppress vibration on the side opposite from the cutting action, promoting accurate sawing and prolonging tool life.

Maximum cutting capacity is 560 mm and the smallest dimension that can be cut is 25 mm x 25 mm. The band guide arm adjusts automatically to material width. Shortest residual length is 10 mm for individual offcuts and 35 mm in automatic operation, enabling operators to minimise waste.

Two electrically driven, plastic brushes keep the teeth free from chips. They are easy to replace and are automatically adjusted throughout their service life.

Having an installed weight of 4.3 tonnes and a rigid welded structure with vibration-optimised ribbing, the KASTOwin pro AC 5.6 ensures quiet operation, short processing times and accurate cutting. A powerful coolant pump and large reservoir serve to reduce wear on the teeth further, especially when sawing difficult-to-machine materials.

The bandsaw comes with EasyControl, a high-performance control unit that is easy to use and reduces idle times in automatic operation for maximum output. All parameters can be optimised to match the type of blade and the material being cut
