When weighing the choice of replaceable-tip mills and drills or solid-carbide tools, consider this succinct statement from one industry expert: carbide equals cost.
Located in their new North American Tech Center, LK Metrology offers a new CMM measurement services department for performing contract dimensional inspection.
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.
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.
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.
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.
Basic trends in modern manufacturing are driving growth in 3D optical metrology. “One is the highly complex and high-tech material that manufacturers are using today. For example, in the aerospace turbine blade market, they simply cannot touch the part like they used to—the surface finish of the material is too readily affected by any kind of contact metrology."
Technology is changing ever more rapidly. Sometimes this means topics learned in engineering or technical school become obsolete. Whole new fields emerge within a few years, so that even those with freshly minted educations suddenly find themselves faced with new challenges.
Celebrating its 80th year, Kennametal, the Latrobe, (PA), tooling manufacturer, says it has solved the age-long problem of tool stability when drilling in deep cavities, alongside tall shoulders, and past bulky fixtures. Reaching deep inside a workpiece to drill holes can be challenging.
