Lathe machining is a method of processing in a cutting tool called a bite, which is used to cut an object, and cut a rotating object with a fixed bite. This method is generally used for machining of round objects. It is processed while the object is fixed in the chuck and rotated. By changing the bite, it is possible to process the outer diameter, holes, cuttings, etc. By using an NC lathe or turning center equipped with NC, it is also possible to perform complex machining such as grooves, spherical surfaces, and curved surfaces.
