One thing that’s certain in developing the most cost-effective solutions for part-off and grooving applications is that there is not just one way to approach the problem and meet basic process requirements for chip evacuation, tool life and surface finish.

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.

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.

It’s an old challenge: You’re a manufacturer whose customer needs you to assure that the part you’ve contracted to make for them will be held to specified tolerances. So, what’s the best method for making sure the part is within spec?

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.

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.

February 2020 U.S. cutting tool consumption totaled $188.2 million, according to the U.S. Cutting Tool Institute (USCTI) and AMT – The Association For Manufacturing Technology.

New operating software of optical CMM machine enables user independent measurement and evaluation of 3D data.

Sales figures don’t lie: indexable cutting tools—featuring removable cutting tips called inserts—are a smash hit with machine shops.

Live tooling, as the name implies, is driven by the CNC and the turrets of various spindle and powered sub-spindle configurations on CNC lathes.
