CUTJET L3-1530-O

 

The CUTJET L3-1530-O Open Type Fiber Laser Cutting Machine is a "high speed" 2D cutting machine for cutting flat sheets(black sheet, aluminum, stainless). It works on the principle of "Flying Optics". This means; The cutting table on which the sheet is placed remains fixed, the cutting head moves in the X and Y directions and performs the cutting process. With this method, very high acceleration values are reached, and also with the direct encoder measuring system and precision racks, parts are cut with maximum precision.

 

Properties

 

• All axes work through maintenance-free, dynamic, and high-performance AC servo motors.
• The machine body is manufactured on a steel chassis machined body, with aluminum construction machined bridge axis structure. In this way, by preventing vibration that occurs in high-accelerated movements, precision cutting can be done.
• The fumes generated during laser cutting are vacuumed or a multi-cell suction system is used to send them to the atmosphere.
• The operator can pick up the cut or wasted parts from the side pickers.

Laser Source


The laser beams to be used for sheet metal cutting are produced in the laser unit. The beams produced in the modules of the laser unit are easily carried to the cutting head by fiber cable without any loss. The laser power supply has a structure that does not change the beam profile between 10% - 100% power levels of low-mode kilowatt class lasers. This feature allows the same laser to be used in both low and high-power operations.

 

The long-range stable beam diameter feature of the Raycus laser allows the use of long-focus lenses. This means a deeper processing area without damaging the lenses. Raycus lasers, which can be used at distances up to 100 meters, allow easy adaptation of different fiber diameters. In addition, fiber lasers are superior to other laser types in that they do not need mirrors, precision mirror adjustment, laser gas, and their light and small structure.

 

  • Superior Beam quality
  • Beam quality that can remain constant at different power levels
  • Small focusing feature at long working distances.
  • Maintenance-free operation
  • Small size, easy to install
  • Compact, robust, and easily adjustable.
  • Diode life>100,000 hours

 

 

Laser Cutting Head

 

The beams produced in the laser unit are carried to the cutting head with a fiber cable. The cutting head focuses the beams received from the fiber cable to the machining surface.

 

There is a ceramic piece on the nozzle in order to prevent damage to the head in case of accidents such as the laser cutting head hitting the lifted or turned upside down cut sheets during cutting. In such unsolicited status situations, this part breaks and prevents the head from being damaged. When the ceramic piece is broken, it should be replaced with a new one as shown in the figure.

 

The capacitive sensor in the cutting head ensures a stable focus position by keeping the distance to the sheet steady. The capacitive sensor system keeps the distance between the nozzle and the sheet steady by quick control of the Z-axis. The laser head is water-cooled so it’s not affected by thermal changes. With the standard F 100 mm cutting lens, the material types, and thicknesses in Table 1-05 are cut.

 

 

Chiller

 

The chiller is the device that cools the optics in the cutting head of the laser source. It has a water-based cooling system.

 

Due to the double-circuit system, cooling water is sent to the optics and the laser source at different temperatures as they need it. The water cycle in the cooler works as a closed circuit. Pure water is used as cooling water. At temperatures below 0°C, up to %30 of the water tank can be filled with pure alcohol. (This operation can be applied down to -10°C)

 

 

Machine Main Body

 

The machine is not equipped with a safety cabinet designed to protect the operator and personnel around the machine from laser radiation and mechanical moving parts. Occupational safety rules and operating rules must be followed for extra safety practices.

Controller Unit

 

CYPCUT 2000 is a special CNC control unit developed for fiber laser cutting applications together with the PCU.

 

The pre-cut parameters of standard materials in certain thicknesses are entered into the system by ROBJET instructors. Considering these reference values, the operator improves the cutting quality with small adjustments according to the changing sheet qualities.

 

  • Laser power is controlled by a function of path, speed, and movement
  • Closed loop distance control is available
  • Optional functions are available.
  • 6 MB internal user memory and USB port available

 

 

Software

 

  • Fully automatic cutting
  • Advanced optimization
  • Fast toolpath impact protection (tool path optimization to prevent damage by sheet deformation)
  • Automatic lead point
  • Cutting Direction (Supports cw or cww)
  • Advanced corner treatments provide perfect corners and smooth cuts (Rounding, cooling, deceleration, cycles)
  • True-type fonts (Text can be written or engraved on the part in any font supported by the operating system)
  • Z-axis control (ping-pong, head-up, deep)

 

 

Lubrication

 

Our machine has a full-automatic lubrication system. In this way, the maintenance time of the machine is reduced, and the hard-to-reach points are easily lubricated.

 

The central lubrication system works with the principle of increasing the pressure by the pneumatic pump with the reducer and distributing the oil to the lines through progressive distributors.

 

With the central lubrication system, linear cars in the X, Y, Z axes, ballscrew shaft nut, and bearing in the Z-axis, racks on the X and Y axis are automatically lubricated with different oil flow rates.

 

 

Security

 

The laser cutting system is equipped with safety elements. While these switches and sensors protect the operator from hazards, on the other hand, they protect the laser head and the machine from damage as a result of incorrect measurement programming of the system or collision of the laser cutting head and the part.

 

The existing diagnostic system also allows the operator to make necessary corrections while keeping the operator constantly informed about the system status. The steps to be taken after the warnings given by the CNC Control Unit are clearly displayed on the control screen. When working with the machine, occupational safety regulations must be fully complied with
