YILMAZ SK 450 Automatic Saw

The SK 450 is designed for repetitious straight (90°) cutting Aluminum extrusions. The SK 450 is equipped with 2 servo motors and a PLC unit so the feeding and cutting process is fully automatic with an accuracy of +/-0.1mm. One of the servo motors is to drive the automatic material feeder. The other servo motor is for the blade feed. Saw blade is straight up-stroke. The operator can enter feed rate, cutting speed, cutting length, cutting height, and number of cuts via touch screen display or through the cutting list.

Modes of operation include: Cutting From List, Normal Cutting (manual entry), Single Cut

Cutting lists are prepared in Microsoft Excel (csv) and transferred to the machine with USB memory stick. Alternatively, they can be made by using the touch screen. If the cutting list function is not used, “Normal Cutting” mode allows the operator simply to enter the required length and quantity and start the process. Also single cuts are possible just like a traditional upcut saw. 

The work table separates before the saw blade retracts to avoid back-cutting. SK 450 can cut from 5mm (0.2”) to 600mm (23.6”) lengths in one stroke and up to 9990mm (32¾’) with step feeding. Equipped with profile detection sensor for auto shut down when job is completed or profile is finished. 

Safety hood is interlocked and cannot be opened during the cutting operation. 

  • Automatic 90° strait cutting operations for extrusions made of non-ferrous material
  • High precision servo motors and ball screw linear motion system
  • Servo controlled profile feeder
  • Servo upstroke saw blade feed
  • Blade feed speed and stroke are controlled from the screen
  • Horizontal and vertical clamping of the work-piece during the cutting operation
