Customers using the new Rasacut XXL during the past few months say that, depending on the workpiece, cutting time is up to 90% below that of up-to-date band saws. The company adds that an improved cut quality is achieved with regard to perpendicularity and surface roughness.

The increase in productivity is said to be mainly due to the drive of the saw. With up to 40kW, the saw drive attains a rated torque of up to 1500Nm.

The machine has been designed to cope with a wide spectrum of workpieces from 20mm dia upwards. These can be produced in fixed lengths between 50 and 3000mm. Saw blade changes, for example from HSS to carbide, are made with few manual movements since the saw head is easily accessible. Usually, it takes the operator ab
