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.

Most manufacturers finish their sintered ceramic parts with grinding equipment designed for metals. Tratech Corp., however, has introduced what it says is the first commercially available CNC grinding machine designed specifically for the demanding needs of machining fully sintered ceramics.

Proactive security measures become even more important as manufacturing software moves into the cloud, machine tool intelligence and automation continue to grow, and the Industrial Internet of Things makes big data an increasingly big deal.

All shops are concerned with burrs, a natural side effect of cutting. They are all looking for a single solution to prevent or remove burrs. Unfortunately, there is no panacea.

As automation becomes more flexible and less expensive, work cells are propagating at smaller shops.

A growing number of manufacturers in the medical industry are seeing the light when choosing a machining option for micro parts and features. The light they're seeing emanates from laser micromachining systems.

Manufacturing microscale endmills and drills requires ultraprecise machinery and specialty grinding wheels—never mind extreme skill, the right carbide grade and abundant patience. Thankfully, a number of toolmakers have become proficient at this microscopic task, leaving shops to worry about just one thing: making parts.

Three primary elements play a heightened role when machining molds for plastic injection molding of microparts compared to moldmaking for the macro realm: part size, feature size and dimensional tolerances.

Machinist's Corner Columnist Michael Deren shares a cautionary tale for vendors and machine shops. Do your vendors realize how important they are to you? Do they appreciate your business or do they think they're the only game in town?

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.
