For the New Giddings & Lewis V-Series VTL, the “V” Stands for “Value”

Fives Giddings & Lewis has long had a sweet spot for vertical turning centers. Its VTC series of vertical machines established the company’s reputation for a solid machining platform and operational versatility, especially with shops that prefer to mount workpieces on a horizontal rotating table, which simplifies clamping and protects ring-shaped parts that might otherwise be distorted in a vertical chuck. For shops producing jet engine components, vertical turning represents an especially advantageous “sweet spot” among machining processes.

This week, Fives is introducing a Giddings & Lewis vertical lathe with a 1,600-mm table for its V series to complement the 800-, 1,000- and 1,250-mm models in this series. The rigidity and flexibility of these models make them popular with shops that must strongly consider value in machine purchases—that is, getting an affordable machine without compromising capability.

“In the last 10 years or so, we saw that the market for a larger turning center was growing, but we didn’t have a V-series model to match this segment,” says Peter Beyer, the company’s sales and application director. The new V-1600 is designed to hit this new “sweet spot” and fill a gap in the company’s vertical turning offerings.

At the booth, Fives has a demo intended to highlight the capabilities and features of the new Giddings & Lewis machine. “We looked hard at the customer base to see what they needed in this size machine. For example, we engineered a 50-hp table but made sure a shop could take advantage of the full power of this table by providing the appropriate features for heavy but highly accurate cutting applications,” Beyer says. These features include heavy-duty table bearings, dual scale feedback, a hydrostatic ram and adjustable crossrail to maximize rigidity for heavy, chatter-free cutting and improved part finish typical in jet engine machining and parts with hard metals such as Inconel. That is why the demo workpiece combines the most common and challenging features found in the typical jet engine component, he says. “None of the power in the table or the rigidity in the machine structure gets wasted or goes unused, because the entire configuration and construction of the machine are matched to this capability. We will put this machine up against any machine in its class.”

In addition, because value is important to job shops, the rigidity of the machine helps prolong the life of cutting tools, reduces tooling costs and minimizes tool changes. And the rigidity for roughing cuts can help them produce accuracies and finishes that eliminate or reduce semi-finishing steps, another important processing economy. In addition, using standard modular tooling such as Kennametal’s KM80 or Sandvik Coromant’s Capto C8 holders and accessories means that tooling up the V-1600 need not break the bank for a job shop.

The Giddings & Lewis V-1600 in Fives’ South Hall booth is the tall-column version, showing that workpieces requiring additional X-axis height have a place on a vertical machine. The show machine also has the milling spindle option, enabling this model to mill, drill and tap turned parts in one setup. Beyer sums it up aptly: “It’s a sweet machine, that’s the most I can say.”

Future of manufacturing

I’d like to ask everyones help in imaging what US manufacturing will become. In my area (Houston) oil and gas manufacturing is huge. I think O&G employs almost 20% of the entire metro area! But it’s clear that the global desire for oil is on the decline which means there will be a vacuum within the manufacturing sector. In addition the sentiment of the country seems to be wanting to move away from plastics and other products with a negative environmental impact.

How do we shift US manufacturing moveing away from O&G and the numerous industries that surround it in a way that supports both business owners and working class employees?

Last month we shared an incredibly impressive example of how you can do some pewter casting with a laser cutter. Since pewter melts at a relatively low temperature, materials like MDF can withstand the heat wel enough to be a decent mold. However, that tutorial really needed a laser to create the details and 3d effects.

On twitter, Dave Sanderson showed a great example of how things don’t need to be so complicated.

in his example you can see how cutting simple shapes in wood, and layering them will let you create 3d shapes out of the molten metal. Looking at his elephant you can see that you could realistically do this by hand if you wanted, or with a jigsaw, no fancy laser cutter required.

As you can see by looking through the media on his twitter account, Dave simply broke down the elephant into basic shapes in roughly 5 layers, then cut them from wood with a nice lined up hole for some bolts going through the whole stack. He bolted them all together and poured in the pewter and voila! A 3d sculpture from 2d simple cuts.

The Federal Reserve reported October 2020 industrial production rose 1.1%.

October 2020 industrial production rises

Per the Fed, October 2020 industrial production rose but remained 5.6% lower than the pre-pandemic level in February.

However, the Fed also noted the industrial production index has recovered most of the 16.5% decline posted from February to April.

Manufacturing gains

As the U.S. continues to battle the pandemic and its impacts across the board, manufacturing showed positive signs in October.

Manufacturing output ticked up 1.0% last month after a 0.1% increase in September.

Nonetheless, the sector still has a ways to go. Manufacturing output in October remained 5.0% below its February level.

Manufacturing capacity utilization rose 0.7 percentage point to 71.7%, up 11.6 percentage points from April. However, the rate remained 6.5 points below the long-run average (1972-2019).

“The index for durable manufacturing stepped up 0.9 percent, as small drops in the indexes for furniture and related products, fabricated metal products, and motor vehicles and parts were outweighed by gains elsewhere, especially for aerospace and miscellaneous transportation equipment and for miscellaneous manufacturing,” the Fed reported.

Meanwhile, the index for nondurables ticked up by 1.2%.

Mining output slips

Meanwhile, mining output in October fell 0.6%, the Fed reported.

Furthermore, oil and gas extraction fell in October after rising in September.

On the other hand, the utilization rate for mining dropped to 77.9%. The long-run average for minig is 87.2%.

Employment gains

Meanwhile, on the job market, the Bureau of Labor Statistics reported manufacturing sector jobs rose by 38,000 in October.

Even so, manufacturing employment remained down by a whopping 621,000 jobs compared with February.

In the metals sectors, the fabricated metals sector saw employment rise by 7,000. Meanwhile, the primary metals sector added 6,000 jobs.
