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.


Boring

 

(in Russian, rassverlivanie), mechanical working of an existing hole with a drill in order to increase the diameter. It is done either by machine, using drilling and boring machines, lathes and other metalcutting machines, or by hand, using pneumatic or electric drills. The precision achieved is of the fourth to fifth class, and the surface roughness is of the second to third class.
