So you’ve heard all sorts of good things about Swiss-style, sliding headstock CNC lathes and have been thinking about investing in one.

Holemaking. A layperson might think, “what could be simpler?” But a machinist knows better because there’s a lot to consider when creating a streamlined toolpath.

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.

While the initial investment for a modular quick-change tooling system is higher than that of traditional toolholders, significantly improving the connection between spindles and tooling is well worth it.

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.

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.

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.

Machine operators can replace time-consuming manual setups and gauging with the precision of digital metrology through a conversational CNC interface.

While fossil fuels dominate the energy market, expect a new mix of parts as renewable energy and EVs grow in market share.
