Machining

While it's nearly impossible to quantify the most common challenges or most important considerations when turning, experts agree that the five aspects of turning discussed below should be considered. It's important to note that each factor has the potential to impact the others.

When drilling, perhaps no variable is as important as the workpiece material. It dictates drill geometry and substrate, tool coating, coolant application, and speeds and feeds. While known for its relative softness and ductility, misconceptions abound among those who regularly drill aluminum.

Italy-based Samputensili S.p.A. unveiled a machine that eliminates the need for cutting oils when manufacturing gears, thereby reducing grinding costs. During grinding, oil-based lubricants cool the workpiece, as well as reduce friction and help evacuate chips. On the downside, however, oil use accounts for a significant amount of a grinding operation's total cost.

Everyone crashes, I was once told. It's likely true. However, not all crashes are created equal. There are fender benders that just break small tools, and then there are head-on collisions that ruin much more—including your day. CNC machine crashes are relatively easy to avoid. They often occur during setup and debugging.

Additive and subtractive manufacturing may be conceptual opposites, but a new partnership aims to show that the two can make a good team. Two of the partners are New York organizations: the Rochester Institute of Technology (RIT) and Elmira-based Hardinge Inc. RIT researchers are incorporating additive-manufacturing capabilities into Hardinge's Bridgeport GX 250 5-axis vertical machining center.

Ask the Grinding Doc: When I ran out of single-point dressing diamonds and got desperate, I mounted a PCD insert to dress an Al2O3 wheel. Is there any danger in doing that?

With 2015 being a year of changes and volatility in our market, the importance of strong, supportive business relationships was made even clearer. Longtime business associates became friends, and new business relationships formed with former employees who stayed in touch, neighbors, contacts made through my local chamber of commerce and even my brother's gym-workout partners.

Perceptron Inc., Plymouth, Mich., recently launched the Expert Coordinate Measuring Machine, a CNC multi-sensor system that seamlessly integrates touch-probe and laser scanning functionality into a single measuring station, according to a company news release issued Feb. 8.

With version 4.7 of the Sinumerik Operate graphical user interface software, Siemens Industry Inc. reportedly improved multi-tasking with machine tools, according to a company announcement release today.

GF Machining Solutions, Meyrin, Switzerland, announced in January that Antonio Faccio replaced Bernhard Kasper as head of the European market region, according to a Feb. 1 company news release. Kasper, who held the position for more than 15 years, will retire this summer.

Seco Tools LLC, Troy, Mich., has further optimized the high-precision reaming performance of its modular Precimaster Plus™ indexable head system by adding floating and adjustable shank designs to the mix, the company announced in a news release today.
