Machinability of 4140 Steel?? - Practical Machinist

Jul 24, 2019 · 4140 is very nice to machine and the pre-hardened version is a real winner for surface finish. Try 400 fpm for roughing, .020" feed and as big a DOC as you have horsepower for. I was doing .19" DOC in a 3" diameter pre-hardened bar while testing a new Iscar tool (.032 nose rad) and that was about the limit for my 10hp spindle.

machining 4140 Engineers Edge Forum

Although there are several materials tougher and of which work harden more readily, it is a strong consideration while machining 4140 steel. One reason is because poor drilling methods (or with dull drills) may weld or embed protions of the drill itself into the work area. This creates a serious problem often resulting in the work being scraped.

Turning Process, Defects, Equipment

Turning is a form of machining, a material removal process, which is used to create rotational parts by cutting away unwanted material. The turning process requires a turning machine or lathe, workpiece, fixture, and cutting tool. The workpiece is a piece of pre-shaped material that is secured to the fixture, which itself is attached to the
