Gangs vs. turrets: Turning Performance
If you're shopping for a Swiss-style CNC lathe, the available options and machine configurations are truly staggering. Spindle speeds that compete with many machining centers, convertible spindles that turn a sliding-headstock machine into a chucker, thread whirling capabilities, laser cutting heads and enough axis letters to become the next Words With Friends champion.

Getting a grip: Drilling Performance
There are numerous advantages to rigidly holding a workpiece: feed rates can be increased and cutting times reduced, cutters last longer and impart finer surface finishes, and more-accurate parts are produced. At trade shows where vendors offer demonstrations, you rarely see flimsy, difficult-to-hold parts being machined.

Mother of machine tool parts
When it comes to highly accurate machining technology, jig boring is better. So say proponents of the century-old machining technique. In the early part of the last century, jig boring started as a better way to make holes. But the technology has since evolved into a more-versatile machining option.

Testing, testing…: General Industry Coverage
How often should a metalworking fluid be tested? It depends. Metalworking fluid is used in most machine shops, because it aids in evacuating chips and cooling and lubricating the tool/workpiece interface. To optimize fluid performance, it must be maintained, which is done by testing a fluid for performance and chemistry.
