Punch-Laser Combo Engineered to Optimize Throughput
Amada America, Inc., Buena Park, CA, introduces the LC-C1NT combination punch- laser machine, engineered to reduce the time required to transition a sheetmetal blank between modes from the typical 5 sec. down to as little as 2.2 sec. The cumulative effect of this time savings across a full sheet of nested parts, say company officials,
can easily add up to 2 min. or more per sheet of reduced run time.
In addition to the reduced tran- sition time, the C1 has been designed with new Y-axis punch- and laser- positioning drive modules that employ digital direct-drive servo motors, eliminating the need for gearboxes. This provides positioning accuracy to ±0.003 in., some 25 percent more accurate than machines that use a gearbox in their Y-axis drives,
the company says.

Experts Solve Press-
Pit Challenge for
Automotive Stamper
Progressive-die stamper and tool and die shop Wellington Industries, Belleville, MI, recently installed a 2000-ton press that required a unique foundation solu- tion. When preconstruction soil testing revealed a water-soaked sand base insuf- ficient to support the 1 million-lb. press, machine-foundation and press-pit experts Delta Industrial, Chesterfield, MI, exca- vated the site to remove the sandy soil.
The 22-ft.-deep excavation project required support by 30-ft. steel pilings; Delta pumped water from the pit through six well points. Then, after allowing the ground to dry, Delta used an epoxy-based non-shrink grout for the press pit that the firm says is five times stronger than concrete. During press installation, Delta
