Dear Doc: I sell grinding wheels and frequently find myself pulling my hair out when recommending wheels to customers. One customer achieved great success with a resin-bond, 400-mesh diamond wheel when grinding ¾"-dia. carbide endmills.

I'm thankful to share that our machining business has picked up and we're running near capacity. I can't get overly optimistic just yet, but good news nonetheless. We haven't required new equipment, new employees or a second shift, but that could change if business continues at this pace or improves.

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.

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.

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.

Lindquist Machine Corp. is a custom-machinery builder that relies on its CAD/CAM system to keep its workflow flexible, break bottlenecks and reduce lead times. The Green Bay, Wis., shop has one programmer to do complicated programming, but most of the workers on the shop floor can write, or at least modify, programs.

Hypertherm Inc. designs and manufactures plasma, laser and waterjet cutting systems, as well as CNC motion and height controls, CAM nesting software and consumables. The Hanover, N.H.-based company opened a 165,000-sq.-ft. facility—Hypertherm's newest—in Lebanon, N.H., in 2012.

Teach your robot well: A new control system can reduce the time to set up and program industrial robots from an hour or more to just minutes, according to the Finnish research organization that developed it.

Networking option: Could the introduction of a small electrical cabinet turn out to be a big step toward more widespread implementation of the Industrial Internet of Things? This special electrical cabinet, called the SmartBox, was developed by machine tool builder Mazak Corp., working in collaboration with networking equipment provider Cisco Systems Inc.

... in these golden years," crooned the late David Bowie in one of his smash hits.The term "golden years" is also used in Albert B. Albrecht's book "The American Machine Tool Industry: Its History, Growth, Restructuring & Recovery," which he revised in 2015 for the third edition.

In today's hypercompetitive, globalized economy, businesses are pressured to do more, do it faster, do it right the first time and do it all with fewer resources.

Presented this month are more programming tips to help prevent machine tool crashes.
