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.
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.
Tool coating is ubiquitous. The variations are dizzying. And, we’re at an inflection point in the technology in the U.S. So, whether you’re a tool user or a tool manufacturer, it’s a good time to dive into this topic.
Adaptive Milling. Dynamic Motion. hyperMILL. Profit Milling. VoluMill. Waveform machining. If you’re one of the lucky people who machines parts for a living, chances are about 50-50 that you’re using one of these or a comparable high-performance programming technology.
For machine shops in a competitive global marketplace, keeping spindles running and making product is the only way to stay in business. Still, adding a new piece of equipment, even with the promise of improving the efficiency of your existing ones, may be a difficult sell to management.
For Dale Mickelson, Yasda product manager at Methods Machine Tools Inc. (Sudbury, MA) and author of several books on hard milling, tackling heat-resistant superalloys (HRSAs) requires the perfect combination of machine, workholding, tooling, tool paths and coolant.
At the Nirvana Machine Shop on planet Perfection, every workpiece is clamped to a custom-built fixture mounted on a dedicated machine tool. Each workpiece is dimensionally identical to the one before and the one after. All the fixtures are totally automatic—instantly positioning, clamping, machining, inspecting, and releasing the part with the ultimate precision.
Do you have what it takes to raise your milling productivity to the next level? In addition to the requisite know-how, you need cutters and machine tools that will allow you to employ milling techniques that exceed what’s normally possible. Aided by the right hardware, you may soon be performing feats like pushing your feed rates to new highs and cutting harder materials than ever before.
Swiss-style machine tools can be a good choice for making complex parts. On the downside, however, Swiss machining itself has a reputation of being complex—and, therefore, more difficult to master than standard machining.
In a perfect CNC world, the first part is always a good one. There’s no need for extra blanks or barstock. Setup times are only as long as is needed to swap out a few tools and load a new program. There’s never a crash, never the need to reprogram an inefficient bit of code. The operator just pushes the green button and out pops a finished workpiece minutes or hours later.
