Motion Mechanics Spindles
from Machine Tool Maniacs · host Matt Dvoracek
In this continuation of our Machine Talk series, Will Mund and I set out to cover multiple components and ended up going deep on one of the most critical parts of any CNC machine: the spindle. Whether it’s spinning the cutter in a mill or spinning the part in a lathe, the spindle is what makes material removal possible. We break down what separates a good spindle from a great one, what impacts precision and longevity, and what to look for when evaluating a machine. We also briefly touch on gibs and drawbars, and how those supporting components play a role in overall performance and reliability.
