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

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.

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.

Recycling equipment manufacturer Harris Equipment Co., Cordele, Ga., saved 50 percent per job tapping Hardox 450 steel wear plates by switching to taps from Emuge Corp., West Boylston, Mass.

Workholding needs to be super-sized when machining workpieces like truck transmission housings, wind turbine blades, rocket bodies, and more, for industries like aerospace and defense, agricultural, energy, marine, rail, and on- and off-road transportation.

Mold-and-die shops thrive on the latest technology in tooling, software, and machines. Process success often depends on using best-in-class solutions from the past as well as from the latest advances of today. New ways of using older technologies often depend on advances in enabling technologies.

The evolution to high speed machining (HSM) is continuing and toolholders are playing a crucial role in that process, which includes the interlinking of machining center, programming, high-speed spindles, advanced cutting tools, balancing, and high-performance toolholders in order for shops to take full advantage of HSM.

At first glance, ceramic cutting tools appear doomed to failure, but the reality is just the opposite.

Machine shops use a variety of techniques to track the condition of their cutting tools, ranging from simple to sophisticated. No matter what monitoring method is used, it can be crucial in preventing catastrophic tool failure. At its best, monitoring also significantly boosts tool life and slashes tooling costs.
