Thanks to the material feed unit and optional automatic mitering, the PSU 450 M runs in the automatic mode. With its optimized sawing parameters, the newly designed clamping system with self-adjusting clamping units and PLC controls, the PSU M is ideally suited for single piece and mass production.

The PLC control of the PSU M offers user friendliness and extremely short programming procedures for a reliable automatic operation. Only the number of pieces to be cut and the length of the pieces to be cut need to be entered into the program. Miter angles within the range of left and right hand side up to 30° acute angle can be adjusted manually. The NC longitudinal axis positions the feed grippers by a servo motor, ball screw spindle and encoder.


The saw unit is provided with a completely hydraulically controlled, variably adjustable drive with electric stroke limitation by potentiometers for both directions, upward and downward. The robust saw unit combined with a powerful gearbox and rapid positioning times ensure short cycle times. Other feature include:

  • Base frame with integrated coolant pumping system and chip drawer
  • Automatic, raisable hydraulic gripper feed unit
  • Continuously variable hydraulically controlled saw blade feed
  • Self-adjusting hydraulic clamping units with clamping-pressure reduction controls
  • Servo motor axes for precise, high-speed material and length positioning as well as mitre angle adjustment
  • Flood coolant system
  • Hydraulic system
  • PLC control with graphic display and keypad
  • Powerful, 2-speed, pole-changing motor
  • Saw blade speed 46/92 SFM
  • Heavy-duty gearbox with shock-absorbing feature for long saw blade life
  • Thick, steel plate base for vibration-free cutting

The machines of this series are not only available in a wide range of available equipment variants, they can also be tailored to your very own specific requirements:
