U.S. companies that adopt electromagnetic workholders heartily endorse the technology.

Eagle Machine Inc., in Abbotsford, B.C., frequently takes on challenging jobs, such as modifying a diving bell for deep-sea submarine rescues or designing and machining a set of solid aluminum wheels for an 800-mph land speed car based on an F-104 jet aircraft. Owner Steve Green said, "People come to us with the craziest things because other people tell them, 'the only place you can go is Eagle Machine.' "

Machine tool users can access the information contained in a stability lobe diagram to greatly increase productivity.

The timing of the IMTS trade show in Chicago last September couldn't have been better for Jason Bromiley. As vice president and co-owner of John R. Bromiley Machine Co. Inc., a job shop in Chalfont, Pa., Bromiley has the lead role in company plans to expand into aerospace manufacturing. Early last fall, the firm already was working on attaining the requisite certification (AS 9100B and ISO 9001:2008). And, as IMTS rolled around, Bromiley was in the market for equipment that would both streamline his shop's current w

Applying "off-the-shelf," standard milling tools to get the job done provides several benefits: the tools are readily available and usually from numerous suppliers, their prices are competitive and the results are predictable. Nonetheless, even with a multitude of standard tools available for nearly every milling application, parts manufacturers often require specials engineered for a specific application.

Because of the array of precision functions grinding machines perform, it's vital to properly maintain them to keep them operating at their peak in terms of accuracy and reliability. You can start by devising a maintenance program and sticking with it. This article provides tips on how to set up key parts of that program.

Manufacturing is an energy-intensive activity. The U.S. government estimates that manufacturing consumes about one-third of the energy used in the country, stated Scott Hibbard, vice president of technology for Bosch Rexroth Corp., Hoffman Estates, Ill., in his paper "Six keys to sustainable manufacturing."

Because they produce chips at high operating temperatures, often with oil-based coolants present, machine tools can easily catch fire. However, if shops plan ahead for this possibility by installing fire suppression systems, they can avoid catastrophic damage to the machine and the shop itself.

Drilling, milling, EDMing, laser cutting, trepanning, punching; there are almost as many ways to make holes as there are holes to be made. Drilling, the most common holemaking method, itself includes many tool material and configuration options.

Shops seeking to true and dress superabrasive grinding wheels need solutions that move beyond 'tried-and-true' methods.

Abrasive waterjet cutting has grown along with the increased use of composites in airframes, and advanced techniques help make it a preferred technology.
