Older plasma and laser cutters having performance fits?: Retrofit!If you are considering retrofitting existing equipment to not just expand your plate cutting capacity, several factors need to be considered. These factors focus on a higher wattage resonator or an higher amperage plasma system, but also on the need to review the entire machine architecture.

Fabricator finds tubular niche: Job shop uses laser cutting to complement CNC machiningProduction Cutting Services was founded in 1985 as a machine shop to supply parts to agricultural equipment manufacturers in and around East Moline, Ill. It used saws and CNC machining centers to provide tubular parts, but later realized it needed to add more value. It purchased two lasers from Mazak Optonics Corp. It hasn't abandoned CNC machining, though. It uses the lasers to complement its other processes.

Keys to success in laser welding: What every laser user needs to knowAlthough a firm grasp of laser physics, metallurgy, tooling and fixturing, weld process parameters, and part strength testing is necessary to implement laser technology in any manufacturing facility, it's also critical to think of other issues that will impact the success of your laser use. Some keys to a successful laser project include involving production personnel early in the process, choosing a laser technology advocate, considering your shop's ambient environment, using trained operators and maintenance personnel, and planning for spare parts and maintenance.

Welding with diode lasers: This laser technology may prove attractive for thin metal applicationsHigh-power diode lasers are just beginning to make an impact on welding applications. They are also physically smaller than other lasers, and their initial capital cost is not as large as it might be for traditional welding lasers because diode lasers have fewer system components.

Laser system saves damaged military parts from the scrap heap: Process limits heat-affected zone to repair delicate componentsAt military installations across the country, repair personnel struggle to stretch the life spans of vital pieces of equipment. Sometimes welding can extend the life of damaged components in aircraft, tanks, and other military vehicles. But in some cases, high–temperature welding processes do more harm than good, warping and weakening delicate metal components. Previously such components would be classified as irreparable and replaced with pricey new parts.

Fitness equipment manufacturer pumps up: Laser leads the way in cutting flat and tubular partsParamount Fitness Corp., a manufacturer of strength training equipment, used to purchase small quantities of laser-cut parts from outside vendors. Its desire for a laser could not be justified because the quantities of parts were so low. Engineers at TRUMPF worked with Paramount to create special fixtures so that a TC L 2530 sheet metal laser could handle tubular parts. The company soon found the new laser running 10 hours per day, six days a week. In keeping with the company's strategy to reduce direct labor, it soon justified a TUBEMATIC to handle its tubular parts.

To buy or not to buy?: Service center struggles with laser questionMetalen Verhoestraete, a metal service center in Roeselare, Belgium, needed a laser, but not just any laser would do. Because many of the company's clients had 3- and 4-meter lasers, Metalen sought a laser that had a much longer bed so it would not compete with its customers.

A new dimension in lasers: Tilt laser beam technology combines 2-D, 3-D laser cuttingHigh-speed laser cutting is a recent result of increased laser power and high acceleration motion technology, which have improved cutting speeds. Tilt beam 2D-3D systems allow laser cutting of small 3D parts, bevel cutting on 2D sheet metal and 3D parts, 3D trimming of small deep drawn parts, and processing of holes and cut-outs in hydroformed parts.

Breaking speed barriers in laser cutting: Technology development synchronizes two unique cutting axesA real breakthrough in high-speed laser cutting occurred in 2005. Two additional parallel kinematic drive axes were placed near the point where the laser exits the head, creating a laser cutting machine with one dynamic and light cutting torch capable of independent movement along two axes but working in precise synchronicity with the machine's more sweeping movement of the laser head. This new approach opened up new frontiers and much higher limits in processing speed.
