With great power comes great responsibility, the saying goes. And with greater laser power being used to weld sheet metal, tubes, copper and aluminum, operators have a greater responsibility to deliver that power with a precision that avoids defects.

When Meyer and Ida Cohen founded Meyda Tiffany Co. in the early 1970s based on a family hobby of making stained glass windows, it’s doubtful that they ever thought it would evolve into the leading U.S. manufacturer of custom and decorative lighting.

Laser welding is a superior technology for repairing defects in tooling, plastic injection molds, stamping dies, blow molds, turbine blades, and nearly any tooling component made of stainless steel, aluminum, copper alloy, cast iron, and all tool steels.

I’m always amazed by the wide range of technologies that go into the process of machining. At EASTEC 2019, I saw the latest and greatest technology from machine tool builders, cutting tool manufacturers, measurement providers, software developers, and many more.

Materials science has opened new possibilities for designers of cars, planes and other products. Metal alloys are now as precisely engineered as they are machined. The result is longer lasting, stronger parts. But with a wider selection of materials comes risk—how can you be sure that one piece of gray metal stock is different than another? Careful warehousing procedures and paperwork only go so far.

The International Federation of Robotics (IFR) in 2016 showed unit sales figures in 2015 up 15% on the year before, reaching an all-time high of 253,748. Since 2010, technical improvements in robots and automation have turbocharged investment, according to the report.

If there is a primary goal for what companies in this sector want to deliver to their customers it is quality. But throughput comes in a fairly close second.

Glenn Bridgman describes the difference between his shop’s manual grinders and its newest state-of-the-art CNC ID/OD grinder, a Studer CT960 OD/ID from United Grinding (Miamisburg, OH), as “feel vs. facts.” Bridgman, president of Bridge Tool & Die (Buckley, MI), believes that manual grinding is a somewhat personal operation.

The energy industry is often at the forefront of our minds as we watch fuel prices climb and then celebrate when they come down. We continually find ways to be as energy efficient as possible in our homes and workplaces. Media outlets keep us constantly informed of this often-volatile industry’s ups and downs.
