Turning is the processing of metal or any other material by cutting. The cutting tool has a high hardness and is made from special tool steels. The processing of the outer and inner surfaces of the material makes it possible to obtain the required shape according to the drawing, which subsequently allows the finished part to perform a rotational function.
As a rule, turning works are provided if the parts have a cylindrical round or conical surface. Facing, chamfering, cutting, fillet machining, grooving, internal and external threading are performed mainly on lathes.
Turning is one of the most ancient technical operations, which was mechanized using a primitive lathe.
The workpiece clamped into the chuck rotates, and the translational movement of the cutting tool or cutter performs the cutting function. The surface finish of the part being produced most often depends on the feed rate of the cutting tool, as well as on the rotation speed. The accuracy of these works is also directly dependent on the condition of the equipment, in particular the lathe, the sharpening of the cutter, the technical characteristics of the lathe and, of course, on the experience and qualifications of the turner.
