Boring

 

(in Russian, rastachivanie), a mechanical process for machining interior surfaces by boring (cutting) tools in order to increase the diameter of a hole. Boring is done on lathes, boring machines, and other metal-cutting machines. It is possible to machine blind and through holes, both cylindrical and conical, as well as grooves and slots. Boring yields a machining precision of classes 4 or 5 and a surface roughness of classes 2 or 3.
