A part may be turned in a lathe, sent off for hardening and tempering and then ground between centers in a cylindrical grinder.
Secondly, how does a lathe dog work? A lathe dog, also known as a lathe carrier, is a device that clamps around the workpiece and allows the rotary motion of the machine's spindle to be transmitted to the workpiece.
