DIY: Creating Through-Tool Coolant Capability

New retrofit systems make it possible to quickly, easily and cost effectively transform the standard external-coolant live tooling heads on turning machine turrets into those with through-tool-coolant capability. And shops that have done the retrofit are experiencing longer tool life, more efficient chip control and less heat generation.

What’s Next in Grinding?

Many precision grinding machines on the market already offer their users near-perfect tolerances, leaving one to wonder: What’s next in grinding? But tool builders still have plenty of room to add valuable new improvements, machine shop owners say.

Not Going Down the Drain

Metalworking fluids have never been the most glamourous part of manufacturing. That’s been reserved for areas such as additive manufacturing, where complete parts are printed from a digital file, one layer at a time. However, most manufacturing today still consists of parts being cut, shaved or otherwise machined.

Milling vs. Grinding for Rapid Stock Removal

A recent effort by the Norton Advanced Applications Engineering Group demonstrates that for difficult-to-machine materials, grinding can be an economical alternative to other machining processes.

Advanced Technologies for Machining Oil-Field Parts

Despite falling oil prices, the investment valve in the oil and gas industry remains on—for now—as manufacturers continue their race to provide large, precision parts for fracking, subsea drilling and other related activities. But as anybody in the energy sector knows: this is the land of boom or bust.

Extrusion and Drawing Knowledge

Extrusion and drawing, two related, stalwart topics in material forming, are covered from top of punch to bottom of die in more than 200 papers in the SME Technical Paper library. The range of contributors is broad, from companies like Alcoa, Westinghouse, ASEA, Western Electric and General Electric to universities in Japan, Germany and the US, as well as individual entrepreneur metalworking shops.

Change-up Pitch: From Metal to Plastic

Even though it’s been around since the 1950s, when engineering-grade resins were first introduced, many manufacturers still are not familiar with the many benefits that metal-to-plastic conversion provides.

Mix and Match for Lightweight Autos

It is common sense—a vehicle that weighs less requires less fuel to move it. A number of studies show that reducing the mass of a vehicle by 10% results in anywhere from 4.5 to 6% better fuel economy—well worth the effort.

Interpreting the Language of GD&T in Metrology

The industrial world is continuing its adoption of Geometric Dimensioning and Tolerancing (GD&T), the advanced tolerancing methodology. The symbolic language is intended to be both more precise while providing more latitude in allowable variations, replacing the simpler method of adding tolerances to each dimension.
