    1. TRANSPORTATION AND STORAGE 1.1.State of delivery The Cut-True 31H cutter is dispatched by the manufacturer in the complete assembled state and ready to operat. The machine is equipped with side-tables which will be delivered unmounted and have to be installed refer to drawing 1.
  • Page 3 1.2. Cutter levering Drawing 2. Adjustment of cutter positioning The cutter does not need to be fixed to the ground. A correct and stable positioning of the machine is done by adjusting the foot rotation, shown in Drawing 2 . It is responsibility of the user to create such working conditions for the cutter to be set properly to eliminate possibility of the operator injury.

  • Page 6: Construction Of The Machine

    2.3. Construction of the machine e cutter consists of three main mechanisms: knife, clamp and backgauge drives and other additional devices. 2.3.1. Knife driving mechanism Drawing 4. Kinematic diagram of the knife driving mechanism The driving mechanism for the knife is shown on Drawing 4. Hydraulic double – acting cylinder (actuator) 1 is fixed on the knuckle 2.
  • Page 7 work tables plane. Inclination of the slide ways at different angles allows inclination of the knife bottom edge at the same angle, when the knife moves down. It decreases a force required for cutting, and the cutting accuracy is increased. The knife is so guided that in its bottom position the blade is parallel to the under knife cutting stick, and penetrates it up to 0,5 mm depth.
  • Page 8 – acting cylinder (actuator) 1 through the levers 2, pulls clamping beam 3 down. Clamping beam 3 is shifted in the slideways (not stated on the drawing) , that guarantees its parallelism to the cutting line. Lowering down the clamp bar 3 is possible also by pressing foot pedal 4. Pushing the pedal 4 moves the bar 5 into the lower position.

Backgauge position set Setting the position of backgauge is done by program module 1 or the fine tuning manual crank 2 - drawing 11.The program positioning and operation of backgauge is described in the program module manual. For manual movement of the backgauge press crank 2 in and rotate it forwards or backwards.
  • Page 17 5.2 Clamping Bar The cut material is clamped automatically after pressing both cut cycle buttons 1(drawing 12) . To press the material without cut, press the foot pedal. The material is pressed until the pedal is released by operator. The clamp force is adjusted by knob 2 of force regulator 3 (drawing 12) Rotating the knob moves the indicator 3 in the box up when increased and down when decreased.
