Circular edging and rip saws
ORP 750/120 a 750/160 Edging and ripping saw
The machine is intended for lengthwise edging of sawn-timber in exact widths, for the production of rods, or for lengthwise cutting of prisms and balks - ripping. In the basic design, the machine is equipped with one fixed and one movable saw sleeve; when required by a customer, another movable sleeve can be added. One or two saw discs can be put in the fixed sleeve, from one to three saw discs can be put in the movable sleeve. When ripping is required as well, the machine should be equipped with a special ripping saw sleeve. The machine can also be delivered as only a ripping one.
The sturdy frame of the machine is welded from steel sheets and profiles. It is equipped with three lower and two upper feeding cylinders driven by means of a cylindrical chain which is propelled by a geared electric motor.
Regulation of the speed of movement in the scope of 5-90 metres per minute (depending on the type) is possible thanks to changes in the frequency of the feeding current.
Exact adjustment of the height of upper cylinders is carried out mechanically through a screw and a draw bar. The precise spindle of the machine is located in antifriction bearings which feature high load-bearing capacity, and is propelled by V-belts from the main motor. Chromium plated surface of the spindle lowers the wear. The performance of the main motor is determined according to the purpose of use of the machine (it depends on the height of the cut material, speed of movement, number of saw discs). Fast and reliable restructuring of the movable saw sleeve is provided by a hydraulic cylinder, the system is equipped with an electronic location scanning system. Adjustment of the cut width is easily controlled from the operator´s seat through the control board. The hydraulic set is incorporated directly in the machine.
The machine is equipped with two upper lines and one lower line of efficient retainers for backward projection of the sawn material. Movable parts of the machine are equipped with safety covers and if these covers are open, the machine cannot be turned on. The covers are equipped with anti-noise coating. Large holes in the lower part of the frame make removal of waste fairly easy.
