When choosing among coated-abrasive flap discs to remove metal and finish parts, grit size is just the beginning.

Bar feeders, once known as slow and inefficient 'rattle tubes,' are now high-speed, automated units.

Significant progress in metalworking productivity most often results from the combined efforts of toolmakers, machine tool builders and software developers. Plunge, or Z-axis, milling is a good example.

As the U.S. strives to become less dependent on foreign energy sources, energy producers are increasingly employing hydraulic fracturing, or "fracking," to drill shale deposits and extract natural gas and some oil. That booming market requires a range of parts from shops around the country.

Where there are drilled holes, there are burrs. The only question is how large the burrs will be, according to Dave Lopes, vice president of sales and marketing for Cogsdill Tool Products Inc., Camden, S.C.

Dynomax Inc. is taking self sufficiency to a new level. For example, while machine tool builders often use their machines to produce parts for making other machines, Dynomax stands out by building machines for its own contract part manufacturing operation.

As demand for vehicle transmissions and other systems requiring quieter, more compact and lighter gear mechanisms increases, gear manufacturers seek to continually boost productivity while lowering costs.

Robust and stiff often come to mind when considering the characteristics that make for a productive milling machine. However, Juanjo Zulaika, a researcher at the applied-research center Tecnalia Research & Innovation, thought otherwise and developed a "softer" milling machine with reduced weight and stiffness. That's achieved while increasing productivity.

States near the Marcellus Shale, a huge natural gas formation centered in Pennsylvania, are feverishly pursuing a $4 billion ethane "cracker" to be built by Royal Dutch Shell. The cracker will process ethane-rich gas from the Marcellus Shale into ethylene, and the ethylene will be used by the pharmaceutical, chemical and plastics industries.

Many large corporations are well versed in total productive maintenance, but smaller companies are probably not. To learn more about the concept, I attended a 1-day seminar about TPM at a local technical college.

At my shop and others I've been in contact with, cash flow and timely payment have become issues that require greater scrutiny. If that's the case at your shop, dealing with them effectively will be a test of your management skills.
