In 2006, Jim Pontillo, founder of TRA Medical Inc. (Placentia, CA), saw two distinct trends: his medical mold-making workload was diminishing and demand for guns and gun components was rising. Sizing up TRA Medical’s core competencies, Pontillo saw an opportunity for growth in the development and production of 9-mm handguns. Today, these guns are branded and sold under their own brand FMK Firearms, which is a stand-alone business.

When sizing up an application for a milling toolholder, it is necessary to consider the materials being machined, how aggressively metal is going to be removed, and any machining conditions that are likely to present a challenge to tooling security. By now, the pros and cons of hydraulic, mechanical, and heat-assisted shrink-fit systems are well known and results well documented.
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.
A 1965 Shelby Cobra 427 shown at the Detroit Auto Show was additively manufactured on a Cincinnati BAAMCI machine by DOE’s Oak Ridge National Laboratory (ORNL), one of seven founding members of the Institute for Advanced Composites Manufacturing Innovation. The Detroit IACMI branch will get $70 million to develop a robust supply chain to improve materials, handling, and machining properties for automotive composites.
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.
Don’t overlook advanced technology available for removing the gnarliest burrs from parts large or small
Machine manufacturers are working to streamline the gear-making process, to deliver a more highly finished gear in fewer steps.
A fully programmable B axis is the latest advanced technology for Swiss machines.
The challenge of machining hip replacement implants out of cobalt chrome
That huge backlog of aircraft being recorded by the global giants Boeing and Airbus, along with a lengthening list of regional aircraft, is stretching the supply chain’s capabilities to machine the newest difficult-to-machine materials.
