The regrind process for tube mill tooling - Part I

April 11, 2006 | By Chris Miller

Although most tube and pipe producers don't get too involved in the regrind process, it is crucial—reconditioning roll tooling can extend its useful life by 15 or 20 times. The regrind process reduces the producer's overall out-of-pocket tooling expenses, while helping to ensure the tooling continues to produce a consistent-quality product at the required speeds. A better understanding of the process, especially familiarity with the types of flaws that reconditioning can and cannot resolve, can go a long way toward a better working relationship between a tube and pipe producer and its regrind contractor.

April 11, 2006 | By Eric Lundin

Newspapers and business magazines are filled with stories about offshoring, layoffs, and plant closings. Quasar Industries, a prototyping and low-volume production shop near Detroit, has bucked this trend and recently increased its manufacturing capability when it purchased a new building. A diverse fabricator, the company provides tooling development and also does stamping, laser cutting and welding, robotic welding, tube fabrication, and machining. The company's client base includes the automotive, appliance, and aerospace industries, among others. But all the equipment it has and processes it performs don't make it successful. Its success is a result of its employees' expertise and its corporate culture.

Metalfab: All that glitters is metal

April 11, 2006 | By Kate Bachman

Lights. Camera. Fabricate?! You get home from work after fabricating all day, kick back with a cool one, and turn on the tube just to see more metal fabrication, on-screen, as entertainment. If it's not "American Chopper" or "Monster Garage," it's "Biker Build-Off," "Monster House" or "American Hot Rod." What's the fascination with fabrication?
