Grinding Gamma Titanium Aluminide

Titanium aluminides possess many characteristics that make them highly attractive for high-temperature structural applications in automotive and aerospace industries. Their high specific strength, high-temperature stability and oxidation resistance relative to conventional titanium and nickel alloys make them beneficial for use in low-pressure turbine blades for aerospace engines, as well as turbochargers and exhaust values in automotive engines.

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.

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.

Automation: The Right Job-Shop Choice

Mention automation and most people think high-volume production environments in which millions of parts are pumped out on a regular basis. While that may be true in many instances, it is definitely not the case at Choice Precision Inc. (Whitehall, PA).

Automating the Grinding Process

Whether the process is cylindrical or profile grinding, automation, which can increase cycle time, throughput, consistency of part quality and taking real-time in-process measurements, is once again in demand. The reasons can be found in the benefits found in typical applications and the innovative and effective forms of automation available from machine builders like United Grinding Technologies Inc. (UGT; Miamisburg, OH), and their automation integrator of choice, Matrix Design Inc. (Elgin, IL).

Machining with Robots

Robotic machining technology has advanced to where it poses a serious alternative to metalcutting applications on more traditional machining centers. With the latest robotics equipment and related software, automation suppliers and robotic system integrators are gaining some traction using robots in many material-removal applications previously done only with machine tools.

Edge Finishing — Product Enhancement or Wasted Cost?

Edge finishing is a relatively new term in manufacturing. It’s a new and deeper focus on what many used to call deburring, edge honing, edge preparation, edge prepping, burring, chamfering, or edge blending. Edge finishing goes beyond any of those definitions. Deburring, which is often considered wasted effort by managers, wrongly carries a negative connotation. In reality, deburring and edge-finishing processes add many benefits to parts—they create highly desirable edge quality—the quality most products need.

Tool-Coating Advances Continue

New coatings are going the boutique route, using multiple layers and new materials to optimize for a particular application

Medical Implants in One Setup

Supplying the 700 level-one trauma centers in the US is an intensively competitive business. Not only must suppliers like Smith & Nephew Orthopedics Inc. (Memphis, TN) produce very fine surface finishes on implantable devices and surgical instruments made from difficult-to-machine materials, but they also must deliver quality products, as surgeons need them.
