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.

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.

End mills, traditionally made with two to four flutes, are used in one of the oldest mechanized machining processes—milling.

ANCA Inc. opened its technical center expansion May 23-24, 2018, in Wixom, MI, hosting more than 200 customers, vendors, and community members at the event. This multi-million-dollar investment provides a larger demonstration floor, classrooms for training, and a larger machine assembly and process development area.

Solid-carbide micro cutting tools about the diameter of human hair or smaller—some producing parts visible only under a microscope—are making a huge impact on manufacturing highly advanced electronics, automotive and aerospace fuel injection systems, and medical instruments and implants.

If John Winter of toolmaker Sandvik Coromant (Fair Lawn, NJ) were to start his own machine shop, all of his machines would be equipped for through-spindle coolant (TSC).

Additive manufacturing (AM) pioneer Charles Hull introduced the first commercial 3D printer, the SLA-1, in 1987. Jaws dropped, machinists wondered about their next career, pundits said it spelled the death of traditional manufacturing. None of that happened, thankfully; in fact, some said 3D printing was a bunch of hype, good for little more than investment casting patterns and proof of concept prototypes.

For Dale Mickelson, Yasda product manager at Methods Machine Tools Inc. (Sudbury, MA) and author of several books on hard milling, tackling heat-resistant superalloys (HRSAs) requires the perfect combination of machine, workholding, tooling, tool paths and coolant.

Cryogenics offer an alternative to traditional liquid coolants when conventional cooling methods can’t or don’t do the job well enough.

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.
