Creep-feed Grinding Is A Milling Process | Modern …
Nelson Beaulieu, grinding product manager with Hardinge Inc., says it makes more sense to characterize creep-feed grinding as a milling process. After all, creep-feed grinding employs a deep cut and a high metal removal rate, and it features a low feed rate in place of fast reciprocating motion. The "tool" in creep-feed grinding—the ...

0.38, and the specific grinding power is just over 10 Hp/in. When developing new creepfeed grinding applications, it is common to estimate the spindle power requirements in the range of 12-18 Hp/in to initially develop the process. These values can also be used to estimate grinding forces on new fixture and part designs for new applications.
Creep Feed
Creep-feed grinding is characterized by increased depths of cut ae and much slower table speeds vw. With increased depth of cut ae, the length of the arc of contact lk increases exponentially, following a square root function ƒ (lk) = lk x (ae)1⁄2. (Doubling the depth of cut ae will increase the length of arc lk by √2.) There are many advantages of creep-feed …
