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.

Hi-Tech Industries of New York invests heavily in automation, including a new laser cutting center and robotic press brake--large investments unusual for a typical job shop. But this is no typical job shop.

Fiber lasers have enormous potential in metal fabrication. They aren't a panacea, but for certain applications, they may be extremely attractive. They're solid-state, require less maintenance, and often can cut twice as fast as their CO2 counterparts.

Upgrading the laser resonator or undertaking full laser cutting renovation represents an alternative to the expensive proposition of purchasing a new laser cutting machine.

Now processing a greater variety of materials with their lasers, fabricators are exploring new assist gas blends of up to four gases. What's the best way to blend and deliver these gases? For some, on-site blending systems can help optimize cost savings and improve quality.

If the proper laser beam focal position and projection shapes are maintained within the material to be processed, the balance of the requirements necessary to producing a consistent, high-quality laser-cut are kept to a minimum. That's why it's important for laser cutting equipment operators to know the rules of laser beam focusing.
The high-powered fiber laser now can take on the work of the blanking press.

Beverlin Manufacturing Inc., a tube producer and component fabricator, struggled with various cutting processes. Its produces and fabricates perforated tube which, because of the perforations, complicates the cutting process. After using two sawing methods, it changed to laser cutting.

Matrix Metalcraft, Clinton Township, Mich.,has done plenty of prototype and production work for the automotive industry in the past, but with the downturn in the industry, it is targeting industries aligned with alternative power generation for new business. In doing so, it has found out that its laser cutting capabilities will serve those efforts well.

Typically, compressed air or nitrogen circulates in the plenum to ensure that water, dirt, dust, smoke, haze, and solid particulate matter are absent so that the mirrors in a laser resonator do not become cloudy. In recent years, membrane air dryer systems that provide drying and removal of particulate matter have been developed for flushing the beam path.

Bobcat determined that the nesting software on its laser cutting systems didn't maximize the capabilities of the machines. After the company decided to purchase new nesting software, programmers outlined what capabilities they wanted. The company purchased ProNest® from MTC Software, Lockport, N.Y. The company has gained positive returns from the new software, which enables more control of process specifications.

H.W. Metals offers punching, shearing, arc welding, machining, oxyfuel cutting, and standard and high-definition plasma cutting. The company found that there was more and more work it couldn't do for its customers because some jobs required laser-cut parts. The company decided to purchase a laser to expand capabilities in its current markets by offering an alternative to plasma cutting. In October, the company installed a Prima Maximo laser cutting system, which will allow the company to provide more capabilities to existing customers.
