METAL FORMING & FABRICATING

Fabricating Cranes in Record Time

With increased competition from regional cran builders, one builder has reduced its lead-time benchmark further through lean fabricating and metalworking techniques.

Pressworking Excellence: Precision Deep Drawing: Leaving Little Trace

Project = deep-drawn coffee urn. Eliminate three operators. Reduce Scrap. Reduce Buffing. Yield higher-quality product with fewer secondary operations and less labor.

METAL CUTTING

Careful Handling: Eliminating Part Scratching on Multi-Spindles

Bar straightness and roundness. Stock-stops. Collets. Each can potentially scratch surface-critical material feeding into a multi-spindle screw machine. The key is not overlooking any of them.

Editor's Forum: Before You Move, Do the Math

In today's global world, you must pick up the part and ask, "What is the total logistics cost of this?"

Swiss-Turning Workholding: Gaining a Firm Grasp

The latest Swiss CNCs scream up to 20,000 rpms, producing more parts - dropped complete - per hour than ever. Of course, all this is for naught without proper, precise workpiece support

Welding

Cutting Edge: Net-Shaping Repairs, A Welding Alternative

Military installations have received their mission: Stretch the lifespan of vital equipment. But how do they carry it out?

Aluminum Welding: The Cost and Cure of Porosity

Porosity can be a problem in aluminum welding. Less than 3-percent by volume passes most industry codes and standards. But go over, and costs build, hour by $50-dollar hour.

Automating for Uncertain Volumes

Price pressures make manual welding operations too expensive, while low volumes make automation a not-so-obvious solution.
