There’s more than one way to finish a hole. The most effective option will depend on the number of parts, cycle time and tolerances. One of the most effective options is boring.

Many job shops hold onto traditional, inexpensive tooling systems. ER collets and Weldon flats are tried and true; they work and are proven. At the same time, newer, advanced machining technology, such as multi-axis machines, may perform better when newer, advanced (and more expensive) toolholders are deployed.

Vibrations, chatter marks, and tool failure are all problems that can be prevented with intelligent monitoring and feedback systems.

Unlike its name, the use of shrink-fit tooling is expanding. A shrink-fit toolholder starts with a slightly undersize bore that is heated to enlarge the inner diameter enough to accept a cutting tool and then grip the cutter as it cools and contracts.

The history of cutting tools goes back a ways—a long, long way. Our prehistoric ancestors were pretty good at making stone tools, and the technology has improved from there. I saw how much on a February visit to the Deutsches Museum in Munich, which has an exhibit on the history of machining.

Not long ago, the mention of workholding might call to mind the traditional vise or three-jaw chuck. The integral nature of proper fixturing to successful machining has forever changed that paradigm and made workholding as critical to the manufacturing process as any of the machines or systems of which it is a part.

When weighing the choice of replaceable-tip mills and drills or solid-carbide tools, consider this succinct statement from one industry expert: carbide equals cost.

Vollmer of America has announced an Open House Celebration for its new facility in Findlay Township, Pa., scheduled for Oct. 22-23. Vollmer broke ground on May 11, 2019 at the new site, near Pittsburgh International Airport.

United Grinding North America Inc. announced it has entered into a partnership with Dynamic Machine of Detroit, a Troy, Mich., based CNC equipment dealership.

A Swedish manufacturer of high strength stainless steel fasteners, BUMAX, has reduced the energy it uses for heating and electricity at its Åshammar facility by over 50 percent since 2011 – to significantly reduce its carbon emissions and further streamline the production of BUMAX products.
