ShopBot Tools, a manufacturer of CNC routers, has launched a “virtual workshop” for ShopBot customers and CNC users. While individuals, businesses, and educational institutions work to adapt to the changing environment surrounding the COVID-19 pandemic, ShopBot is providing virtual tools to make CNC accessible to small and mid-sized manufacturers, including education, training, information, support.

East Iowa Machine Co. (EIMCo) in Farley, Iowa, is a full-service machine and fabrication shop. It is an ISO 9001:2015 certified manufacturing company, employing about 150 people on three shifts at its single 130,000 ft2 (12,077 m3) location, and converts raw metals into finished component parts and assemblies using a wide variety of CNC equipment and state-of-the-art manufacturing processes.

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.

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

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.

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.

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.
