Title: FLYING SAW AND FIXED SAW FOR CUTTING EXTRUDED PROFILES AND METHODS OF USE
Abstract:
A flying saw for cutting extruded profiles comprises a circular saw having a saw blade11and a first saw blade drive17 for driving the saw blade to rotate for cutting, a support14for the circu- lar saw on which thecircular saw is supported and adapted to be moved in a first direction FSH, Fin synchronisation with a movement of an extruded profile to be cut in the first direction F, a second saw blade drive15, 16for driving the saw blade to move perpendicular tothe first direc- tion for cutting an extruded profile to be cut, a control13for controlling the first saw blade drive, the support and the second saw blade drive which is adapted to control the rotational speed of the saw blade and the movement of the sawblade in the second direction to obtain a cutting speed resulting from the rotational speed of the saw blade and the movement of the saw blade in the second direction according to a control scheme, and a temperature sensor 12 adapted for de- tecting the temperature of the cutting edge of the saw blade. The control13is adapted to control the obtained cutting speed using the detected temperature of the cutting edge of the saw blade to keep the temperature in a predefined temperature range by increasing ordecreasing the rotational speed and/or the movement of the saw blade in the second direction.
