As new composite materials are developed, parts manufacturers face new challenges when routing them. Fortunately, cutting tool manufacturers continually develop new solutions so parts manufacturers are not forced to cut tomorrow’s composites with outdated routers. 

Most folks who run an engine lathe often work on the ends of long shafts, or rods, that protrude unsupported out of the headstock. Depending on the shaft diameter and how much unsupported length sticks out, this operation can be dangerous because of the high potential for shaft whip. However, with the proper tooling, this operation is a cinch to perform safely. 

Machine tool builder Zimmermann Inc., Wixom, Mich., the U.S. arm of Neuhausen, Germany-headquartered Zimmermann GmbH, specializes in very large machine tool installations. The company offers milling machines with working ranges from 2.5m to 30m (8.2' to 98.4') along the X-axis and from 3m to 6m (9.8' to 19.7') along the Y-axis. 

Just in time (JIT) manufacturing, by nature, increases setups and shrinks batch sizes. This puts shops in a bind, because more setups and smaller batches are typically less profitable; but saying "no" to work can be even more painful. The burden to search out creative ways to reduce cycle and setup time in order to realize a profit falls to the shops that commonly perform JIT work and on the shops that can’t afford to turn it down when the opportunity arises.

A new CS-50 deposition system from Duralar Technologies uses a process called DualArmor that is capable of applying DLC coatings of 50µm or thicker — and apply them at rates averaging 15µm to 20µm per hour. Conventional DLC coatings, which have a practical total thickness limit of around 5µm, are deposited one or two atoms at a time. As a result, it can take more than 8 hours to deposit a 1µm-thick DLC coating. 

Every person who works in a machine shop probably has at least one task they absolutely hate. For Tom Lipton, who writes Cutting Tool Engineering's Shop Operations column, one task stands out above most others: shortening small screws and fasteners. He says he just doesn't not like to do it. 

When your primary market tanks to its lowest level in 30 years, the impact can be drastic, according to the Manager's Desk column in the May 2017 issue of Cutting Tool Engineering magazine. Is your shop well managed and in a position to overcome such a hit?

Craftsman Jasper Röders set up shop during the early 1800s to make pewter tableware for his neighbors in Soltau, Germany. Six generations later, his descendants still produce pewter but have expanded into blow molds and CNC machine tools.
