Fitness equipment manufacturer pumps up

October 11, 2005

Paramount 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.

Blanking questions have you on the edge?

October 11, 2005

By:

Reducing the damaging effects of fractures, burnishing, burrs, and rollover improves subsequent forming processes. The blanked edge condition can be improved by adjusting the punch and die clearance tolerance, shaving the area of the defected blanked edge, designing an appropriate contact profile of the tool and die, and understanding the mechanical properties of the sheet metal used.

Laser cutting and welding with one tool

October 11, 2005

By:

Today's laser sources have the power and beam quality needed to cut and join metal in an expeditious and repetitious manner. The market demands that type of flexible production, so those characteristics are basic requirements in modern laser devices. The market demands also have promoted the idea of multifunctional processing. That has led to the development of a combination head capable of laser cutting and welding 3-D metal work pieces.

Keys to success in laser welding

September 13, 2005

By:

Although 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.

Get your schedule in order

September 13, 2005

By:

The quality of resistance-welded components depends on the weld schedule, which comprises several machine settings. Although many resistance welding machine and electrode suppliers offer standard weld schedules for common metal combination, special weld schedules often are necessary to address increased use of special metals, joint combinations, coatings, and weld-through sealants and adhesives.
