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.

What makes a CAM system “good,” in our opinion, is the quality of its post processor and the technical support provided by the vendor. When programming questions are answered quickly and accurately, and the system produces good code, programming is simplified and machine utilization goes up, while both setup and cycle times drop.

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.

3D Systems announced enhancements to its reverse engineering software products.

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.
