Additive Joins Subtractive on Advanced All-in-One Machines

Senior Editor Jim Lorincz

4/1/2014

The path of precision machining has taken a decidedly unexpected change in direction. Yes, machining centers, in their various configurations of horizontal, vertical, and universal, continue to hold their preeminent positions in shops for their ability to create value-added benefits to individual workpieces or parts in serial production.

Laser Welding Applications Expand



Contributing Editor Bruce Morey

3/1/2014

Lasers for welding have proven their worth in the last 35 years in select applications. Despite their high capital cost, the precise, intense heat source makes lasers the right choice where there are tight tolerances, close fit-ups, and thin materials. These are applications where lasers produce less distortion, with their smaller heat-affected zone (HAZ) around the weld. Full Article

Drilling Small, Deep Holes with Precision EDM



Senior Editor Jim Lorincz

11/1/2013

Electrical Discharge Machining (EDM) has been removing metal by spark erosion for more than half a century—with sinker (ram/Elox-) style EDMing for molds and wire EDM for precision parts cutting, especially dies. A third type, EDM drilling, has emerged for precision holemaking in the smallest sizes, going beyond its use initially as an EDM “popper” for starting holes in hard metals. Full Article

Scaling Down Waterjets to the Micro Level



Senior Editor Patrick Waurzyniak

11/1/2013

Shrinking an abrasive waterjet machine down to work at micro sizes is no small task. Adapting abrasive waterjets for micromachining requires greatly reducing the size of the waterjet nozzles and mixing tubes that carry smaller garnet abrasives through the waterjet’s high-pressure cutting tool delivery system.
