The perfect balance of low energy usage and high speed productivity
Amada, a worldwide laser machine pioneer, introduces the direct drive fiber laser cutting machine, the LCG-AJ. This fiber laser cutting machine delivers higher speed and faster acceleration processing by utilizing a carriage with a lower centre of gravity and the latest motion system incorporating high torque motors and helical rack drives. Combined with an Amada designed oscillator, the LCG-AJ fiber laser cutting machine enhances processing speeds and productivity along with the ability to process highly relfective, exotic materials with ease.
Energy conservation and cost reduction
- The construction of the fiber laser oscillator and optical transport of the laser beam is less complex than a CO2 system. This drastically reduces the maintenance cost of the oscillator and optical parts.
- Amada's fiber laser has a higher energy conversion and 3 times higher energy efficiency than a CO2 laser. Power consumption of the oscillator is also substantially
High Quality Processing of highly reflective materials
The fiber laser has a shorter wavelength and is 3 to 4 times more easily absorbed than traditional CO2 lasers . This enables high-quality processing of highly-reflective, difficult to process materials such as aluminium, brass, copper and titanium.
Amada developed fiber laser oscillator
In a CO2 laser oscillator, laser light is pumped with laser-gas, emitted via the output mirror and delivered by reflector mirrors to the cutting head. The fiber laser oscillator has no need for this.
The monolithic structure allows the laser power produced by the individual laser diode banks to be combined into a single fiber optic cable for direct delivery to the cutting head.
High Speed Processing Of Thin To Medium Thick Materials
1) Lightweight Y-axis carriage
Higher speed is achieved by a 30% reduction in mass of the Y-axis
carriage compared with a conventional laser cutting machine.
2) Carriage with a low centre of gravity
The Y-axis carriage has a low centre of gravity due to a Z-axis height of 100mm, allowing high speed processing of thin materials.
3) High torque motors and helical rack drive
The latest motion system incorporating high torque motors and a helical rack drive is utilized to ensure high speed, smooth acceleration.
HS Capacitance Head
‘One Touch’ Lens and Nozzle Exchange
To allow faster machine setup, the cutting head on the fiber laser cutting machine LCG-3015 AJ is equipped with simple, quick change lens and nozzle cartridges.
Before piercing a mid thick material, oil is sprayed on the material to prevent spatter buildup, thus improving processing quality and achieve stable cutting with the fiber laser cutting machine.
NC Auto Focus Control System and Active Cut
The optimum focal point is automatically set from the cutting database to suit each material. The curvature of the mirrors is altered to keep aconstant focus, ensuring optimum laser beam quality and reduced assist gas costs.
The OVS IV system measures the pitch of two readout holes and automatically compensates for the process origin deviation from the laser machine controler for combination process of program and Laser. The pitch and circularity of the cut holes are measured. When the measured values fall outside the specified limits, an alarm condition appears on NC.
Bar Code Reader
The LCG-3015 AJ fiber laser cutting machine can be equipped with a bar code reader to allow reliable recall of programming data on the shop floor. By scanning the setup sheet from the Dr. ABE Blank CAM software, the laser machine operator ensures the correct, latest version of the NC program is loaded into the laser machine control.
Amada has developed the VPSS (Virtual Prototype Simulation System) digital manufacturing solution to ensure the seamless flow of production data between the programming office and the shop floor. Amada’s CAD/CAM systems are directly linked to the machines via the SDD database across the computer network. This solution ensures reduced programmingtimes and increased productivity.
