Zone: Machining Centers & Milling Machines

OVERVIEW: 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. Most machining centers are “vertical” or “horizontal” based on the articulation of the spindle. While vertical machining centers can be high-end machines because of their precision and/or their size, a small and simple vertical machining center is a relatively low-cost CNC machine tool that often represents a new machine shop’s first machine tool purchase. Vertical machines generally favor precision while horizontal machines generally favor production—but these generalizations are loose, and plenty of machines break out of them. Other choices in machining center orientation include the universal machining center, which can change between vertical and horizontal spindle arrangement. More common than this is the five-axis machining center, which adds rotary motion to the machine’s linear motion. The machine pivots the tool and/or the part not only to mill and drill at various angles, but also to mill swept surfaces.

Secrets to the Art of Hand Scraping

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. ...MORE
