Traditionally used for the manufacture of valves, rings, and other large parts 30" in diameter or larger, a Vertical Turning Lathe (VTL) is a cost-effective solution for the manufacture of parts as small as 6" in diameter. The higher upfront cost of a VTL as compared to a horizontal lathe is often offset by substantial long-term savings: VTLs reduce cycle times and minimize floor space requirements while dramatically increasing tool life by working with gravity, not against it.
Corkscrew milling involves simultaneously feeding on all three axes: advancing on the Z-axis while simultaneously interpolating on the X and Y axes to enlarge the hole. The process, requiring a machine with interpolating capability, is said to out-perform spade drilling, progressive twist drilling, trepanning and flame cutting. Proponents say it often produces a finish good enough to eliminate finish boring.
"Machine Tools" is not a phrase you hear very often these days, and you would be hard-pressed to find it in an index of books on America's economic development, or biographies of inventors. Yet, machine tools and their relatively small group of designers are the lifeblood of a modern industrial economy. A nation which does not have a supply of machine tools is doomed to third- or fourth-world conditions.
Increasingly, manufacturers are turning away from producing offshore and returning production to the U.S.
In November 1995, the U.S. precision custom manufacturing industry was warned that Asian tool-and-die makers had formed a coalition with their governments, targeting new business in the U.S. market.
The response from many American producers was "it won't happen," or "my customers are loyal."
The Asians had a 10-year plan to take over the market.Flash forward to 2009. The U.S. industry has lost over 30 percent of its companies and the jobs they supported. More are in danger as the auto market has ground to a halt.
MAG introduces a fast volumetric error compensation (VEC) system capable of analyzing and correcting positioning errors in all machine-tool axes simultaneously to achieve significantly improved machining accuracies on large parts.
Three + 2 machining is a technique whereby a three-axis milling program is executed with the cutting tool locked in a tilted position using the five-axis machine's two rotational axes, hence the name, 3 + 2 machining.
There's more to leasing or purchasing a turning center than writing a check and keeping fingers crossed. A decision based on needs, capabilities, and costs can help avoid expensive mistakes.
Not since the revolution in aerospace manufacturing has the need for lean solutions that combine composite fabrication and large-part machining been so critical to an industry's advancement as it is now for wind energy.
MAG's new SPECHT® 500/630 horizontal machining center takes modularity to a new level offering linear-motor or ballscrew drives, CAT-40 through HSK-100 tool interfaces, six spindle options, four control options and three 5-axis configurations to suit needs ranging from one-off work in job shops to agile machining lines
The 4-Axis Center-Drive Lathe is ideal for maximizing machining efficiency. One 12-station turret machines the front end of the work piece while a second 12-station turret simultaneously machines the back end. In addition to this integrated workholding capability, the Bardons & Oliver Center-Drive Lathe allows the critical surfaces at each end of the part to be machined concentric to each other.
Messer leads it's respective category in Metal Center News' new Top 10 Service Center Equipment Brands lists for 2010. The final ranking, based on the total number of votes each company received, gives a rough indication of which brands currently command the largest share of mind, and highest levels of customer satisfaction, among service center executives
