A lathe is a machine tool that rotates a
workpiece rapidly; the cutting tool is then slowly moved
into the workpiece, removing material as the piece spins
against it. Lathes are a common part of professional and
amateur workshops, and are highly versatile tools. The cutting bits for a lathe, in particular a metal lathe, require occasional sharpening. Lathe tool bits aren’t like the often fragile bits found on a normal drill; their blocky shape and the overall design of the lathe means that the tool itself does much of the work, not the bit. However, lathe cutting bits do require sharpening or dressing up, refinishing the edges that come into contact with the workpiece and preventing them from rounding off. Bits that have lost their edge can result in chattering or poorly-finished surfaces. |
