Production Cutting Services was founded in 1985 as a machine shop to supply parts to agricultural equipment manufacturers in and around East Moline, Ill. It used saws and CNC machining centers to provide tubular parts, but later realized it needed to add more value. It purchased two lasers from Mazak Optonics Corp. It hasn't abandoned CNC machining, though. It uses the lasers to complement its other processes.
One form of hybrid welding combines both GMAW with a GTAW process in a welding torch. An electronic interface unit containing a plasma power supply controls the hybrid process. Research has indicated that such an approach to welding leads to faster welding times, deep penetration, and cleaner welds when compared with conventional GMAW technology.

In deep drawing of complex, asymmetrical parts such as stainless steel kitchen sinks, blank holder force (BHF) needs to be controlled locally to regulate the flow of the sheet metal. An MPC blank holder system allows this control by placing individually programmable cushion pins around the blank perimeter, with an appropriate BHF selected at each pin location.

Achieving typical goals in stamping, such as zero development and fewer labor requirements, is made easier when the progressive die strip is kept level through the entire progression. Keeping the strip level can eliminate wave problems caused by incorrect pilot/lifter use occurring in punch forming.

Laser equipment specialists claim that an operator now can change the head for cutting up to 3/4-inch mild steel to welding 3-D parts in less than 15 minutes. So the laser cutting/welding equipment has made a technological leap to support the job shops looking to expand their capabilities. But how have the gas systems evolved to support these advanced capabilities?
