Machining Center Drill/Tap Boring Mill Milling Machine Machine Type: The Machine Tool Search Engine job that had consistently produced chatter prob- lems. Among the tools tested for this job were a 1.25-inch-diameter knuckle rougher and 2-inch- diameter finisher. "Again, the results were positive, as the chat- ter was eliminated, and it produced the best finish we have ever seen on these parts," says Curtis Sampson, shop leadman. "After that, we bought 50 more pieces and immediately noticed improvements all around the table. We've been increasing their use over time ever since." According to JMPP President John Stoneback, "By significantly increasing the speed of machines via eliminating the problems that were designed into V-flange tooling, conservative estimate sav- ings of 10 to 15 percent can be achieved. The high-torque knobs transform V-flange tooling into the most cost effective, reliable and precise tooling system available." Since these initial tests, HEC has progressively converted to high-torque retention knobs in its 14 C N C m a c h i n e s, re q u i r i n g a p p rox i m ate l y 120 per machine. Jose Campos, tool crib buyer, says the 15 percent increase in productivity has led to the same rate of decreased downtime due to less change-out of tool cutters across the board. Mr. Campos praises the knobs' performance Two buildings on HEC's 43,000-square-foot-facility campus boast a wide array of major CNC equip- ment including high-speed, five-axis machining centers, horizontal machining centers with dual tombstones, three-axis machining centers, and a machining center with dual-shuttle tables.
