Machining Centers & Milling Machines

The term “machining center” describes almost any CNC milling and drilling machine that includes an automatic toolchanger and a table that clamps the workpiece in place. On a machining center, the tool rotates, but the work does not. The orientation of the spindle is the most fundamental defining characteristic of a machining center. Vertical machining centers generally favor precision while horizontal machining centers generally favor production—but these are loose generalizations, and plenty of machining centers break out of them. Another common machining center type is the five-axis machining center, which is able to pivot the tool and/or the part in order to mill and drill at various orientations.

Secrets to the Art of Hand Scraping

By: Mark Albert
Hand scraping of mating surfaces on a machine tool enables the surfaces to be flatter, more accurately aligned, longer wearing and freer to glide across one another. No automated or mechanical operation can match these benefits. Machine builder Okuma explains how this seeming paradox is true.

Video: Robot Changes Vise Jaws for Continuous Machining

By: Peter Zelinski
If a robot can load and unload parts, why can’t it do the same for workholding? Here is video of a robot changing the vise jaws so the same machining center can run different operations in unattended machining.
