No holes in modern laser cutting story

February 1, 2012

Fabricators want to process metal parts with the least amount of handling as possible. As a result, they are always looking to maximize the capabilities of their equipment. One example is the use of laser cutting equipment to produce high-tolerance holes in a speedy manner, instead of taking metal blanks to a secondary station for additional holemaking activities. Advancements in drive system and piercing technology have given fabricators a chance to raise their hole-cutting capabilities while the sheet remains in the laser cutting bed.

Why beam delivery matters

January 6, 2012

The most powerful laser in the world can’t work without an effective, finely tuned beam delivery system. Its design hinges on the application, but a few basic elements lay the groundwork. Together they provide myriad options to find the most effective way to carry and shape the beam on its way from the laser source to the workpiece.

Nesting software keeps the “lights-out” on

September 9, 2011

By: ,

"Lights-out" laser cutting-defined as a machine laser-cutting parts without the need of operator intervention, typically during an unmanned evening shift-can only occur when the cutting head can move around the sheet unencumbered. Advanced nesting software can ensure that "lights-out" remains on.

Arin Inc. has evolved from a steel rule blanking house to a modern metal fabricator capable of producing precision, laser cut blanks. Bu workers can see history every day--a tool room for steel rule die remains, as do the mechanical presses. A tour of Arin's shop is a walk through time, a gallery showing what metal fabrication talent has produced over the decades.

Gas equipment for CO2 laser cutting: A primer

July 8, 2011

By:

Precise assist gas delivery is essential in CO2 laser cutting. The resonator is a key component, especially if gas delivery will be uninterrupted for unattended machine operation. Assist gas volume and pressure also must be appropriate for the application to ensure the best results.

One laser head, one plasma torch, one cutting table

July 8, 2011

By:

The fiber laser and plasma systems share similar delivery systems. Neither require any kind of optical alignment between the power source and cutting head. The two thermal cutting processes share many similarities, from an integration standpoint, which is why the two now can be integrated onto a single cutting table.

A case of the gas

January 10, 2011

By:

If a job shop supplies metal parts that are to be powder coated or welded, the customers likely require that those fabricated parts have no oxidized edges. That requirement forces the job shop to cut with nitrogen, which doesn't leave an oxidized edge like oxygen. Unfortunately, cutting with nitrogen is expensive because much more nitrogen is consumed when compared to oxygen to perform similar cuts. This situation led a metal fabricator to investigate nitrogen generation systems. This is his tale.
