The elements that make up a lathe are the spindle that grips (grabs) the material and causes it to rotate, and the tool holder that moves the cutting tool. There is an auxiliary push rod to dampen material jumping. Since lathe machining is performed by rotating the material, the parts being machined are machined into cylindrical, conical or spherical shapes. Geometrically, the shape of a cross-section perpendicular to the axis of rotation is a circle. Not only round, but also outer diameter and tapping inner diameter can be machined.
Click to view-Turning And Milling Parts Circular machining has a higher degree of roundness compared to other cutting processes, such as when machining outside and inside diameters, producing products with less runout. In addition, since the diameter can be easily adjusted by changing the position of the tool, it is a machining method that can easily improve dimensional accuracy. In summary, lathe machining can be said to be a machining method suitable for rotating parts such as shafts.

For example, it is difficult to flatten the sides of a cylinder with a lathe, and machining with a milling machine is common. With a lathe, only surfaces perpendicular to the axis of rotation can be leveled.

It is a lathe suitable for heavy workpieces, called a vertical lathe, and has the characteristics of being less susceptible to gravity. Click to view-Cnc Machining Turning Parts In order to improve the machining accuracy of the lathe, the material must be centered when it is clamped to the spindle. In the case of cylindrical materials, a three-chuck chuck is often used. The material does not necessarily have to be round, it can be clamped with a four-chuck collet, but it will take time to center. Mass production-oriented processing requires initial costs, but by preparing dedicated chucks, the processing time per piece can be shortened.

The outer diameter and face machining use the outer diameter tool, the inner diameter machining uses the center tool, the thread cutting uses the thread cutting tool, and the cutting process uses the parting tool. There are two types of knives, one is made by sharpening tool steel to make the cutting edge shape, and the other is used by screwing the tip (blade) to a special handle. Since the accuracy of the type used for sharpening depends on the skill of the person handling it, the type that uses a tip has become mainstream in recent years.
