PKRD 260-A Double shaft ripping saw

The machine is designed for longitudinal cutting of prisms and squares - cutting to precise lumber with a high-quality cutting surface and minimal kerf. The machine is designed for deployment in the most demanding applications - high feed speeds combined with a large thickness of the material to be cut.

​

The machine is equipped with a pair of fixed sawing sleeves (upper and lower) for fixing the saw blades. On the bushings, the saw hinge is assembled with the help of intermediate saw inserts with a maximum pitch of 460 mm of the edge saws. Both spindles are height adjustable, which allows the selection of optimum cutting conditions and thin saw blades. The height adjustment of the spindles is carried out by an electric motor with gearbox.

​

The drive unit with powerful electric motors and belt transmissions is completely separated from the machine itself. The transmission of the driving force to the actual saw spindles is ensured by cardan shafts that connect the spindles and the drive unit. The cardan shafts prevent the transmission of belt bending moment and vibrations to the saw spindles, thus ensuring a stable cut and a long service life of the spindles.

​

The robust machine stand is welded from high quality steel plates and profiles. The material feeding system consists of four toothed, lower driven rollers on the infeed side, counteracted by one driven and one idle upper pressure roller. On the outfeed side, the machine is equipped with a lower chain with transverse carriers against which a pair of upper driven pressure rollers act. The control of the upper pressure rollers is carried out hydraulically. The machine is equipped with two rows of upper backward projection retainers. The moving parts of the machine are covered, with the opening of the covers blocking the start-up of the machine. A large opening at the bottom of the machine allows good waste removal. The saw is supplied with a device for changing the bushings in the machine.

The delivery includes a well-organized control board and an electric switchboard.
