Metalworking and metal spinning both make extensive use of lathes. A lathe is one of the most significant material removal technologies in industrial technology. CNC lathe machines are the most often utilized form of lathe because they are fast, accurate, and the most sophisticated type of lathe. They can cut almost any material including wood, plastic, metal, and even glass.
A lathe consists of a rotating head with cutting tools that remove material from the workpiece. The lathe head can be hand-operated or powered by an electric motor or hydraulic system. Lathes can be divided into three main types: horizontal lathes, vertical lathes, and hybrid lathes. In hand-lathing, the operator turns the head manually while using the other hand to hold the workpiece. With a power lathe, an electric motor drives the head and can either be self-feeding (auto-feed) or manual-fed. A manual-feed lathe requires that the operator put more effort into feeding the workpiece whereas an auto-feeder does this task for the operator. An automatic spindle chuck holds the workpiece during operation of the head. This type of chuck uses pneumatic pressure or mechanical springs to close around the workpiece. A manual spindle allows the operator to place the workpiece inside the spindle before starting the lathe. This type of chuck uses vacuum or magnets to secure the workpiece.
A lathe is a type of machining tool that is usually used to shape metal or wood. The workpiece is rotated around a fixed cutting tool. The primary application is to eliminate undesired sections of the material, leaving a neatly formed product left. Lathes can be divided into two main groups: tail-spin and live-center.
Tail-spin lathes have a motor at one end and a spindle with a single tool attached to it. The other end of the spindle has a ball bearing that allows it to spin freely while the motor shaft continues to turn as the spindle spins. This type of lathe is used when a fixed tool is not needed because either there is only one operation that needs to be done or many different operations could need to be performed with the same piece of stock. For example, this type of lathe is often used by hobbyists to shape small items like jewelry or buttons. Tail-spinning lathes are easy to use and maintain, but they cannot cut very deep into the surface of the material. Also, since the tool is fixed, changing tools is difficult unless the entire unit is pulled out from time to time.
Live-center lathes have a motor inside the body of the machine instead of at one end. This motor drives a spindle with multiple tools attached to it.
What exactly is a lathe? Lathes are available as either hand or CNC (computer numerical control) controlled.
Lathes can be divided into three main groups: horizontal lathes, vertical lathes and hybrid lathes. Horizontal lathes have their axis of rotation lying in a plane parallel with the base of the tool post. Thus, they can cut across surfaces of the workpiece that are parallel with the base of the tool post. Vertical lathes have their axis of rotation lying in a plane perpendicular to the base of the tool post. They can therefore cut along surfaces of the workpiece that are parallel with the base of the tool post, but not across them. Hybrid lathes have their axis of rotation lying in a plane at an angle to the base of the tool post. They can therefore cut both along and across surfaces of the workpiece.
The most common use for lathes is to make parts from bar stock that are then further processed or used in some other way. However, they can also be used to create items by shaping single pieces of material. This may sound like an easy task for a human being, but it is not.
The lathe machine is a power mechanical device that holds and rotates the work against an appropriate cutting tool to produce a cylindrical shape in metal, wood, or any other machineable material. The lathe was invented by Joseph Bramah in 1852.
The basic parts of a lathe include a headstock and a tailstock. The headstock is the part that grips the end of the barrel or handle during operation. The tailstock releases the piece after it has been turned down to the desired diameter. Both headstock and tailstock are mounted on a single shaft called the chuck axis. The chuck axis can be moved back and forth along its length by a motor-driven chuck screw. This allows the headstock to grip different sizes of barrels or handles without changing the position of the tailstock.
A second set of jaws called a cradle jaw set is used to hold the work while being turned. These are attached to the headstock so that they rotate with it. They can be opened and closed by hand or automatically via a clutch mechanism. When operated manually, this process is known as free turning because there is no tool used to cut off pieces as they are turned out. When operated automatically, a small cutter called a mandrel is used to slice through the center of each piece as it is turned out.
