FASTER INSPECTION FEEDBACK IMPROVES PART QUALITY

Let the Good Times Roll: At the Maryville plant of Kawasaki, Renishaw 5-axis scanning probes now collect data and reduce feedback to machining cells from hours to minutes and may ultimately eliminate the inspection systems for gears and cam lifts.

MAINTENANCE

The vertical turning center at Helac does heavy metal removal on the tube-shaped housings used for many actuator models by utilizing a 3-pallet pool of queued work to stay in production during much of the 80+ hour workweek. Workpieces are DOM tubing and alloy steel weighing 60 lb to 500 lb. The tube style parts have welded steel flanges on each end and some have off-center plates on the sides. These are mounted on an angle plate that has half-rounds to locate off the OD of the tube.(Click on photo to enlarge it)

More Power to You: When Helec Corporation retrofitted a workhorse MAG turning center with a new Fanuc CNC and AC digital axis drives/motors and spindle, it utterly brought new life to the entire shop floor.

Visually inspect consumables on a regular basis for signs of spatter, replacing them as needed. Also, consider adding a nozzle cleaning station (also called a reamer or spatter cleaner) to the weld cell. Like its name implies, a nozzle cleaning station removes spatter (and other debris) that builds up in the nozzle and diffuser. Using this equipment in conjunction with a sprayer that applies an anti-spatter compound can further protect against spatter accumulation.(Click on photo to enlarge it)
