Without a doubt, cutting tools for machining titanium must be well-engineered. This was reinforced for CTE Editor Alan Richter while attending Horn Technology Days 2017, held May 10 to 12 at Hartmetall-Werkzeugfabrik Paul Horn GmbH, Tübingen, Germany.

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. 

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.

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.

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 recent report, “Global Ultra Hard Material Cutting Machines Market” by Transparency Market Research, forecasts a healthy compound annual growth rate of 10.8 percent for these machines for the years 2016 to 2024, with the total market reaching $1.8 billion by the end of that period. The report’s authors expect rising demand to lead to more competition and lower prices.

Are you being asked to quote secondary machining operations on a handful of 3D-printed metal parts? If so, how do you cut these parts? 

Cutting Tool Engineering Editor Alan Richter ponders the machine shop of the future in his Lead Angle column for the May 2017 issue.

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. 

New, ultraresilient workpiece materials with high strength-to-weight ratios have cutting tool vendors and CAM developers scrambling to design new tools and toolpaths to efficiently cut them. To succeed, the vendors and developers must collaborate with unprecedented frequency.

In an interview conducted by CTE Editor Alan Richter at a global press event held at the company’s headquarters in Sandviken, Sweden, Klas Forsström, president of AB Sandvik Coromant, discussed his new role, the state of the cutting tool market, the importance of attracting talent to manufacturing, tool recycling and the role of R&D.

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. 

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.

Automation isn’t just a boon to complex, multiple-machine manufacturing processes. It can also give a major boost to processes that involve only a single machine.

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?

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.
