After working in this industry for even a short time, you are in tune with all the things around you that have been created on a metalworking machine tool and realize how extensive the list is. Almost everything made in a factory contains at least one part that was manufactured on a machine tool.

My realization of this came especially clear when I began working in the industry (almost 10 years ago) shortly after my father broke his hip after slipping on a sheet of ice in a parking lot. The screws surgically implanted in his hip bone were created on a metalworking machine, but at the time of his accident, I didn’t think anything of it. During the healing process, Dad had some irritation problems with the screws, and therefore had them removed. When he showed these four long bone screws to me, I remember being in awe of how long they were and how strange it seemed that they were once “screwed” into his hip bone.

These bone screws were created by a metalworking process called thread whirling, which is a common medical machining process. To read more about thread whirling, how it works, what applications are best for this type of machining and more, visit Thread Whirling Basics. Thread whirling is also discussed as a medical application in Tooling Up for Micromachining

  • Swiss-Type Machines: More Than Just A Lathe

    CNC Swiss-Type machines have more capability built in than ever before. Many of these capabilites can be accessed using attachments that increase the throughput of the machine tool, improve the quality of the work coming off the machine and reduce or eliminate the need for secondary operations even for very complex workpieces.

  • Making Micro Threads

    Production of micro threads can be challenging, but using the most suitable tools for a given application can simplify the task.

  • Broaching On A Lathe

    Producing a keyway, spline or similar longitudinal feature on a turned part usually necessitates an additional, time-consuming, secondary operation on a broaching or slotting machine. That means moving the part to and from a secondary operation, an extra setup, additional labor and hourly machine costs and all of the other headaches that go with secondary operations.
