3 Axis 3000X1500 mm Fiber Laser Cutting Machine

ROBJET - 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.

Thanks to this method, very high acceleration values are achieved and with the help of the direct encoder measuring system and precision racks, part cuttings are carried out with maximum precision.

• Moving axes work via maintenance-free, dynamic and high-performance AC servo motors.

•The machine body is manufactured in the structure of the bridge axis with an aluminum construction machined on a steel chassis machined body.

In this way, precision cutting can be done by preventing vibration that occurs in high-accelerated movements.

• A multi-cell suction system is used to vacuum the smoke generated during laser cutting and send it to the dust collection filter or to the atmosphere.

The cut or wasted parts that fall into the used part collection trolleys are collected from the side with the help of the operator.

Laser Power Supply

The laser light to be used for sheet metal cutting is produced in the laser unit. The beams produced in the modules of the laser unit are easily transported to the cutting head by fiber cable without any loss. Laser power supply low - mode kilowatt - class lasers have a structure that does not change the beam profile between 10% - 100% power levels. 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 do not require mirrors, precise mirror adjustment, laser gas, and their light and small structure provides superiority compared to other laser types.

Superior Beam quality (BPP)
Beam quality that can remain constant at different power levels
Small focusing feature at long working distances.
Possibility of maintenance-free operation.
Modular plug & play structure.
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 on the processing surface.

There is a ceramic piece on the nozzle in order to prevent damage to the head in the event of accidents such as the laser cutting head hitting the cut hair that is shielded or reversed during cutting. In such undesirable 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 in Figure 1-01.

The capacitive sensor in the cutting head ensures a stable focus position by keeping the distance to the workpiece constant. The capacitive sensor system keeps the distance between the nozzle and the workpiece constant by quick control of the Z-axis. In order not to be affected by thermal changes, the laser head was chosen as water cooled. Tab with standard F150 mm cut-off lens. Cuts are made in the material types and thicknesses in 1-05.

Cooler

The cooler is the device that allows the laser power supply to cool the optics in the cutting head. It has a water-based cooling system.

Thanks to the dual-circuit system, cooling water at different temperatures is sent to the optics and laser power supply. The water cycle in the cooler works as a closed circuit. Pure water is used as cooling water. Pure alcohol can be put in up to 30% of the water tank at air temperatures below 0°C. (This study 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 (direct or indirect) laser radiation and mechanical moving parts. Occupational safety regulations and operating conditions must be complied with for extra safety practices.

Control unit

CYPCUT 2000 / EMPOWER CNC Controller is a special CNC control unit developed for fiber laser cutting applications together with the PCU it is connected to.

Pre-cut parameters of standard materials (Steel, stainless, aluminum, brass, copper) 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, time and motion.
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 caused by sheet deformation)
Automatic entry point
Cutting Direction (Supports clockwise or counterclockwise)
Advanced corner treatments provide perfect corners and smooth cuts (Rounding, cooling, deceleration, cycles)
True-type fonts (Text can be written or engraved instead of parts in any font supported by your operating system)
Z-axis control (ping-pong, head-up, deep)
Joint Cuts (This feature reduces the need for drilling when machining parts and is particularly useful for thick sheet metal)

Central Lubrication System

Central automatic lubrication is used in the machine. In this way, the maintenance time of the machine is reduced, and the hard-to-reach points are easily lubricated.

The central lubrication system used in the machine 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, ball screw nut and bearing in the Z axis, racks on the X and Y axis are automatically lubricated with different oil flow rates.

Safety

Laser cutting system, machine and CNC control unit are equipped with safety elements. While these switches and sensors protect the operator from dangers, 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's status. The steps to be taken after the warnings given by the CNC Control Unit are clearly displayed on the control screen. Occupational safety regulations must be fully complied with when working with the machine.
