Chris Koepfer has been involved in metalworking for 30 years. His first 14 were in the machine tool group at Cincinnati Milacron where he honed his technical writing skills in turning, machining and grinding before joining Modern Machine Shop in 1992 as an associate editor. In 2001, he helped found MMS’ sister publication Production Machining, which speaks to the precision machined parts segment of the industry. Chris is graduate of Xavier University in Cincinnati, as are three of his four children, and an XU basketball fan—which can be as daunting as working in metalworking, he says.

Worth the Trip

Getting to Elmira, New York is not the easiest thing to do. Earlier this month, I jumped a plane from Cincinnati to Philadelphia to Elmira. Each plane got smaller and smaller, starting with a 50-passenger CRJ and finally a wing-over, prop-driven 20-seater for the last leg. But it was worth it.
The occasion was a visit to Hardinge for its second HMTS (Hardinge Machine Tool Show). The company welcomed more than 750 visitors to the company’s headquarters in Elmira June 6 and 7. A lineup of turning, grinding, milling, automation, rotary and workholding applications were on display in the 50,000-square-foot showroom.
Also included were more than 40 of Hardinge’s industry partners including tooling, software and accessory providers, which rounded out the trade show atmosphere. Technical people from Hardinge’s varied product lines and its suppliers were on hand to discuss technology and applications with visitors.
A neat thing about having a show in your shop is that it allows for a plant tour. Hardinge’s tour consisted of 11 stops throughout the manufacturing facility with presentations by the team members who actually do the work.

The idea seems to be catching—this year’s event covered four times the floor space of last year’s premier exhibition. Elmira may not be on the beaten path, but it’s a worthy destination for metalworking manufactures to see made in America alive and well.

Senator Mitch McConnell Visits MAG

On Friday, March 2, Senator Mitch McConnell dropped by the Hebron, Kentucky facility of machine tool builder MAG. We were invited to listen in as company executives explained the nature of the facility’s business, which is primarily aerospace and renewable energy, and sought help from the senator on issues affecting manufacturing.
The list included export control reform, extended R&D tax credit and bonus depreciation, financing support for the EXIM bank, promotion of job training and creation of a “smart force.”  MAG’s Hebron operation relies heavily on exports, with about 60 percent of the machines built there exported, MAG President Dan Janka explained to the senator.
After meeting with the company executives, the senator addressed the assembled employees with brief remarks followed by a Q&A session. Standing on the main assembly floor and surrounded by large machines used to produce composite components for the aerospace and renewable energy industries, he began his remarks by commenting that it is “stunning what you do here.”

He’s right: It is stunning what companies like MAG and shops like yours do everyday to maintain a critical manufacturing base in this country. Perhaps we keep our light under a bushel basket, but if more of our officials would come out and see what vital and successful manufacturing in the United States looks like, the list of needs from companies like MAG and shops like yours might not only be heard but acted upon.

Stepping Up to the Plate

Home-grown initiatiatives are popping up to help find skilled workers
to replace the aging population already employed.
Well, it’s time to ring out 2011. And barring any last-minute hiccups, according to most information I’m privy to, it’s been a good year for manufacturing.
Shops I talk to are busy and do not see a let-up in the foreseeable future. Even the catastrophe earlier in the year in Japan that lead to critical shortages in many industries seems to be working itself out sooner than was expected.

As we round the corner into 2012, I wanted to mention two bright spots that recently came to my attention. They have to do with home-grown initiatives to help with our industry’s most pressing problem: finding appropriately skilled workers to fill the current demand for jobs and replacing an aging population already employed. Read how two companies are solving this problem.

Trolls Beware!


I just retuned from a delightful and educational week in Sweden as the guest of Sandvik. Every EMO year they put together a pre-show program for the world press. The idea is for us to get a sneak preview of new stuff they will be showing. Twice a year, the company unveils what it calls a “Coropack,” which is made up of some 1,500 to 2,000 new products. Needless to say, there will be many new things at Hall 5 Stand B20.
This was my third trip to Sweden with the Sandvik folks, and each trip has been a perfect blend of work (new innovations, directions and advancements that keep the company at the forefront of technology) and play (doing things Swedish).
This year, we did a Swedish metalworking exercise. Perhaps it was a little tongue in cheek—you know, metalworking editors actually working metal instead of writing about it. I, for one, loved it. With a foundry background, this was not my first time on an anvil.
Our assignment was to make an amulet that is designed to ward off trolls. Apparently they are common in the wood of Sweden. As we were heading into the woods by canoe for a BBQ dinner, I soon realized that the amulet was as important as the life vest. However, the magic only works if you make your own.

This is my amulet, which is worn around my neck to ward off trolls.

We donned coveralls and the smithy had a forge, anvils, hammers and raw material for the group to make the amulet. The real smithy showed us the design and then walked us through the steps to make it. We were then on our own. It was pretty fun to watch this manufacturing process in all of its various permutations. Beating hot metal with a hammer is science; beating it into what you want is the art. Needless to say, in our group we had many scientists and fewer artists. It was fun.

Our smithy showed us how to make our troll protector.


Here is my colleague, Russ Willcutt, working hard on his amulet.
Unfortunately, he failed to properly close the curls on the ends to keep in the luck.
He was carried off by trolls shortly after this picture was taken.

Look for more about the trip to Sandvik in upcoming article in Production Machining.

Road Report: Wish You Were Here, Day 4

It is day four, and we arrive at the reason for traveling to Germany: Grooving tool maker P.H. Horn is holding its Technology Days open house and seminar in Tubingen. Last year at this time, I had my airline ticket in-hand, ready to attend the event. The day before I was supposed to leave, the Iceland volcano closed German airspace. I’m here after waiting a year, and the visit has been excellent. 
The entrance to P.H.Horn’s Tublingen HQ welcomes its guests to Technology Days.
I have a long history with Horn and admire its dedication to the U.S. market as demonstrated by the company’s manufacturing facility in Franklin, Tennessee. It goes well beyond many other OEMs that want to sell here but not manufacture here. We need the jobs. The visit started early with a bus ride from our hotel to the company HQ. Dave Fabry, who heads up the U.S. operation, took us on a spin through the plant.
Dave Fabry, operations manager at Horn USA, stands in front of some of the new CNC machines that the apprentices (photo below) are learning to use.
One of our first stops was at the incredibly large and well-equipped apprentice area. Most German manufacturers have apprentice programs, but this is special both in its size and the quality of equipment these future manufacturers use. Sure they have bed lathes and mills, but they also use brand new DMG VMCs. (Although, I did notice a wooden cutting tool in one spindle, but heck, the kids are learning on state-of-the-art machine tools. Caution is good practice.)

Some of the apprentices in Horn’s in-house program learn about manufacturing.

Next, we meander through the massive grinding hall. Horn uses high-precision VMCs, all DMG, to grind the insert blanks. It also presses, sinters and PVD coats to the tune of 20,000+ inserts a day. After the tour, we sat in on a seminar, which was thankfully in English. Duane Drape, Horn’s U.S. sales manager and a long-time friend of mine, did a presentation on coating technology and manufacturing that I thought was perfect in its level of detail. That stuff can get technically deep. I hope to convert his presentation into an article so you can experience it too.

Duane Drape, U.S. sales manager, imparts knowledge in his coatings seminar.

Horn is a class act, and it’s not just me saying that—more then 2,000 customers and distributors from around the world showed up at this event. We Americans were well represented by almost 50 people who flew over the pond to participate. The take-away from the seminars was they were designed to push process rather than product. Horn gets a lot of tough jobs thrown its way, and it responds creatively and competently to these challenges. It was a day well spent and a trip well worth it.
