Creep-feed grinding (CFG) was a grinding process which was invented in Germany in the late 1950s by Edmund and Gerhard Lang. Normal grinding is used primarily to finish surfaces. But CFG is used for high rates of material removal, competing with milling and turning as a manufacturing process choice.

Move the tool sideway about 1/2 its diameter while going down about 1/8 the diameter; this creates room for the chips to get out. It is not ideal but it works. They leave a very nice finish on the inside of the hole. You will have to go slower than a drill, but there's no problem evacuating the chips.

Creep Feed Creep-feed grinding is characterized by increased depths of cut a e and much slower table speeds v w. With increased depth of cut a e, the length of the arc of contact l k increases exponentially, following a square root function ƒ (l k) = l k x (a e) 1⁄2. (Doubling the depth of cut ae will increase the length of arc l k by √2.)
