EBTEC operates 15 multi-axis laser machines , capable of handling your precision Laser Cutting needs.

Laser Cutting is the collimation of light energy (photons) used to impart energy on a vast array of materials to cut exacting profiles. Coupled to a 5-axis CNC motion control system, this light energy becomes a robust cutting machine tool used to create complex cut geometries across multiple industries.

“LASER – light amplification by stimulated emission of radiation”

We excel in prototype through large-scale production applications and have highly skilled engineering and technical staff available to discuss your potential applications. Our machines utilize advanced Nd-Yag laser systems, and “kW class” fiber laser systems for our laser cutting technologies. Output powers range from 30 watt to 20kw. Additionally, we can perform Laser Engraving on your finished components.

EBTEC maintains AS9100 / ISO9000 certification and NADCAP non-conventional machining certifications as well as a host of OEM certifications.

Laser Cutting Services Include:

Flat sheet cutting
Extremely sharp edge definition
5-axis and 6-axis laser control
3D shapes, corners, slots, and holes with high repeatability
Minimum kerf width
Ultra-low distortion
No variations due to tool wear
Alternative to cutting dies for low-volume production

About Laser Cutting

Laser cutting is a thermal process in which a focused laser beam (photons) is used to melt material in an extremely localized area.

A gas jet is used simultaneously and in line with the laser to eject the molten material and create a cut. The resultant cut width is called the “kerf”, which can be controlled to some degree with lensing. The laser cutting process is controlled by sophisticated CNC control (3-5 axis are typical) that is programmed with CAD/CAM systems.

Your complex models can be imported and exact process cutting can commence reasonably rapidly with intervention of machine controls added to the output from a post process.

Laser Cutting is an advanced process that produces exact cuts in virtually any shape, at any angle, and through materials that would be destroyed by contact cutting tools.

The Advanced Laser Cutting Process

The LASER, an acronym for “Light Amplification by Stimulated Emission of Radiation,” is a device that produces a concentrated, coherent beam of light by stimulating molecular or electronic transitions to lower energy levels, causing the emission of photons. In some of our Laser Cutting equipment, a solid-state laser utilizes a single crystal rod with parallel, flat ends, with each end having reflective surfaces.

A high-intensity light source, surrounds the crystal. When power is supplied by the PFN (pulse-forming network), an intense pulse of light (photons) will be released through one end of the crystal rod. The light being released in our Laser Cutting Services is of single wavelength, thus allowing for minimum divergence.

How it Works

In our advanced Laser Cutting process, 100% of the laser light will be reflected off the rear mirror, and 30 to 50% will pass through the front mirror. The laser light will continue through the shutter assembly to the angled mirror and down through the focusing lens to the workpiece. The laser light beam in our Laser Cutting Service is coherent and has a high energy content. When focused on a surface, laser light creates the heat used for cutting.

The workpiece and the laser beam are manipulated by means of robotics. The laser beam can be adjusted to varying sizes and heat intensity, from .004 to .040 inches. The smaller size is used for cutting, drilling, and welding, and the larger for heat treating.
