Kasto, a German sawing machinery manufacturer, has introduced an automatic bandsaw to make easier the removal of additively manufactured parts from the print bed once building is complete.
Designed to increase productivity, the KASTOwin amc has been developed to bring gains in efficiency, reliability, precision, and safety.
A build platform with additively manufactured parts is bolted to a fixture, the before the KASTOwin amc turns 180 degrees to invert the build platform so when the parts are sawn they fall into a container below. After loading and before sawing, the operator enters the thickness of the build platform via a wizard in the Kasto SmartControl CNC system. Then, the saw unit, which boasts a precise ballscrew drive, moves to the required height and begins to separate the parts from the bed within the specified tolerance.

The KASTOwin amc has dimensions of 2,455 2,075 x 2,325 mm and has a cutting range of 400 x 400 mm, though other capacities are available on request. Sawing is also done upside down, prolonging the life of the 5,090 x 27 x 0.9 mm blade as wear is reduced because swarf also falls away under gravity and less is drawn through the cutting channel. Cooling is provided by a minimum-quantity lubrication system, while welded rigid structure minimises vibration for quiet operation and accuracy. The electromechanical infeed is infinitely adjustable, according to Kasto, and band speed is controllable between 12 and 150 m/min.
Operators of the machine can monitor the process through a window, and have the ability to open a flap or forcibly stop to remove printed parts as and when necessary. specialists in Kasto’s German factory can also remotely monitor the process over a secure internet connection. If needed, they can carry out fast and detailed diagnostics to assist the operator. They also have the ability to transmit programs and adjust parameters, often considerably reducing set-up times and downtimes.
