Methods Machine Tools Inc. (Sudbury, MA), a leading supplier of precision machine tools, 3D printing technology and automation, recently introduced an automation cell designed to greatly boost 3D manufacturing throughput.
Mazak Corp. (Florence, KY) continues its steady advance toward the complete factory digitization of all its manufacturing operations with the recent transformation of its Oguchi, Japan, facility into yet another Mazak iSMART Factory.
Kennametal Inc. (Pittsburgh) announced June 29 that its board of directors has appointed Christopher (Chris) Rossi as president and CEO and has named him a director. Rossi succeeds Ron De Feo, whom the board has appointed executive chairman. Both appointments are effective August 1.
Overall, there are two overriding customer needs: reducing cycle time and machine downtime. They want higher feed rates and depth of cut for greater metal removal.
Today’s products require high finishes, burr-free edges, freedom from contamination, and often close tolerances. Electropolishing provides all of those conditions and more in a matter of seconds for many metal parts. It is a process that has been used for more than a hundred years. It is widely known and the science is widely discussed, but its ability to run job shop lots and high-precision high-volume parts in the same equipment makes it a bit unique.
It is reported that, not too long ago, before the current precipitous decline in machine-tool shipments, the number of 30-taper machines that were being manufactured and sold in Japan had surpassed the numbers of 40-taper and 50-taper machining centers.
Why use a metrology device on or near a machine tool? It isn’t just useful for making sure a tool is present or monitoring tools for wear or breakage. On-machine measurement technologies can save time and money, by speeding up processes and eliminating extra personnel, and they are a critical step in the movement towards “lights-out” manufacturing.
Micro components continue to shrink in size, demanding ever-greater precision and improved handling of parts with sub-micron-sized features. New approaches in micro machining technology include higher-precision systems from traditional micro machining developers, as well as techniques using additive manufacturing processes and semiconductor wafer-scale technology on the smallest of micro parts.
While precision, part programs and productivity have improved markedly, the basic process is still the same.
The adoption of smart manufacturing processes reminds Bob Willig of his “lean manufacturing journey, years ago,” he said.
