All metals are not created equal. Therefore, neither are the machine tools for cutting them. Parts for extreme aerospace applications, such as in engines, landing gear and flap tracks, must be made of a heat- and corrosion-resistant metal, which typically has a high Young’s modulus of elasticity and is difficult to machine. These include titanium, stainless steel and high-nickel alloys.
The “hard metal” machines that process the parts must be stiff, typically requiring a large mass, and have a large servomotor to create lots of thrust. They also need a high-torque spindle to effectively move the cutter through the material and a high thrust load on the axes of the ballscrews, which often have a low 8mm pitch, to offer an effective mechanical advantage, according to Scott Walker, president of machine tool builder Mitsui Seiki USA Inc., Franklin Lakes, N.J. He explained that the machines are built that way because aerospace customers typically run them slower than 600 rpm, require around 2,000 ft.-lbs. of torque and take maximum chip loads from 0.002 to 0.006 ipt. “So you build this big, rugged machine,” Walker said. | View Article

The process of displacing metal instead of cutting it is called many things. But whether they call it form tapping, cold form tapping, thread forming, cold roll forming, roll forming, thread rolling, roll tapping or cold roll tapping, many metalworking professionals are unfamiliar with it, according to Peter Gennuso, applications engineering supervisor for OSG Tap & Die Inc., Glendale Heights, Ill. | View Article

| Trending Toward Productivity

The U.S. economy appears to be on the mend. In January, the Manufacturers Alliance for Productivity and Innovation gave a tentative thumbs up to sustained business expansion through the first half of 2013. And the Institute for Supply Management’s manufacturing index rose again in January, painting an optimistic picture. Maybe it’s time to buy that machining center you’ve been thinking about.
Before you whip out your checkbook, though, some homework is in order. There’s a lot more to machining centers than spindle speeds and rapid traverse rates. Sure, you’ve had good results over the years buying machines based on that, but that might be the wrong criteria in this brave new manufacturing world. You’re facing growing competition from overseas and down the street, so you owe it to yourself to take a look at what’s changed in the years since you bought your tried and true 20"×40" vertical machining center. | View Article
