Control system for bandsaws
September 1st 2006

Danobat has introduced a new control system for its high performance bandsaws.

The PASO PASO system is described as sophisticated, yet simple to use. The operator simply chooses the material to be cut from a list of material groups, selects the material size, and specifies whether it is bar, tube or section.

The machine then takes over and sets its own blade speed and automatically sets the correct downfeed rate. The downfeed rate will automatically vary throughout the cut to achieve optimum cutting rates and give optimum blade life.

For example, with round bar it will enter the cut at a reduced rate to protect the blade and, once the blade is in the material, it will increase the feed to the optimum cutting rate, automatically slowing down as the cross section of material increases, and increasing as it passes through the centre of the material and the cross-section decreases.

While most material specifications are pre-programmed into the machine, there are spare programmes so that companies can add their own specific material groups, if required.

Danobat's intelligent blade deviation is such that instead of simply turning off the machine, it will automatically adjust its cutting parameters to bring the level of deflection back to acceptable and predetermined levels.

Automatic 'running-in' of a new blade – whether bi-metal or carbide – not only eliminates guess work, it allows the operator to input a specific make of blade to ensure that the correct running-in procedure is being followed.
