How Does a Lathe Machine Work?

The lathe is an indispensable processing tool in the manufacturing industry. They are considered to be one of the oldest processing tools, and their origins can be traced back to ancient Egypt. It mainly has the functions of cutting, knurling, facing and turning. So, how exactly does a lathe work?

How Lathes Work

Although there are different types of lathes (see below), they work on the same principle, that is, the cutting tool does not move and the workpiece to be processed is rotating. The milling machine works in the opposite way. With a milling machine, the workpiece is stationary, while the cutting tool rotates.

Lathes are designed to use cutting tools to remove excess material on the workpiece to create a specified workpiece. The workpiece is fixed on the lathe, and the workpiece rotates while being pressed into the cutting tool. The rotational movement of the workpiece helps it remove material quickly, efficiently and accurately.

A lathe is a large and complex machine composed of many independent parts. For example, the headstock is a component that holds the workpiece while it is rotating. The lathe also has a tailstock that can hold the workpiece. Tailstocks are usually used for particularly large or long workpieces.

Types of Lathes

There are nearly a dozen types of lathes, each of which are designed for a different purpose.

A glass working lathe is a type of lathe used for glass workpieces. Glasses and optical materials are usually manufactured by a stationary cutting tool.

Woodworking lathes live up to their namesake by supporting wooden work pieces. They typically operate at a speed of 5,00 to 1,000 revolutions per minute (RPM).

In addition to woodworking lathes, there are also metalworking lathes. Metals are generally harder than wood, so metalworking lathes require a stronger and sharper cutting tool than their woodworking counterparts. Metalworking lathes offer a range of different cutting tools, varying in size, shape and material, but they are all designed to cut through common metals like aluminum and steel.

Of course, there are many other types of lathes, some of which include metal spinning lathes, decorative lathes, rod lathes, and mold-making lathes.

In summary

    A lathe is a processing tool with a rotating workpiece and a stationary cutting tool. 

The work piece is fixed on the headstock or tailstock. When the work piece is pressed 

on the fixed cutting tool, it will rotate the work piece to achieve the required shape of 

the work piece.
