KastoTwin A 4x5 bandsaw fits into mid-range slot
1 min read
German sawing machine and storage system manufacturer Kasto has introduced the KastoTwin A 4x5, 440 by 520 mm cutting capacity bandsaw that sits between its twin A4 and A5 models.
Designed for use primarily with bimetal blades, the KastoTwin A 4x5 mid-range machine is aimed at those wanting to cut stock above the 400 mm diameter capacity of the A4, without having to invest in the more expensive 560 by 630 mm capacity A5.
The KastoTwin A 4x5 is a heavy duty, double column, high performance bandsaw offering rugged cutting performance when processing solids, tubes and profiles, including tough alloys. Kasto has incorporated vibration and noise reducing features from its top-end bandsaws into this mid-range model for longer blade life.
The machine is fully enclosed to ensure operator safety. It stops automatically in the case of blade breakage, blade slippage or in the absence of clamping pressure. The design encompasses not only current criteria but also those recommended by the international safety lobby for future inclusion.
The 850 mm infeed stroke of the material is driven by a ballscrew for accurate positioning. Cut lengths shorter than 250 mm can be achieved using an incremental feed feature that reduces cycle times and increases output. Material height is detected automatically.
To achieve optimum results when cutting different types and shapes of material, the machine is equipped with a frequency controlled saw blade drive with infinitely adjustable cutting speed from 15 to 150 m/min. The hydraulic downfeed valve can be set for constant infeed rate, constant cutting force, or a combination of the two.
Carbide band guides with anti-vibration rollers and heavy duty guide arms contribute to the high precision and longevity of the 38 mm wide. Hydraulic saw blade tensioning is electrically monitored, with automatic pressure reduction.
All functions of the KastoTwin A 4x5 are executed from the Kasto PLC system, BasicControl. This can store up to 99 programs, selectable by a keystroke, to define material size and type, length of billets and number required.
Infeed and cutting cycles are automatic and require no operator involvement once the machine is set up and started. To increase productivity further and reduce material handling, the KastoTwin A 4x5 can be equipped with a range of peripheral equipment such as loading magazines, discharge systems and marking devices.
