Definition of lathes and machine tools

Lathe is a metal processing machine tool, mainly used for the turning of metal materials. The lathe is usually composed of a bed, a spindle, a feed mechanism, a cutting tool, and a tailframe. The lathe has a rotary cutting function and can be used to process different shapes such as outer circle and inner circle. The machine tool is a processing machine in a broad sense, including a variety of cutting, drilling, hydraulic, grinding and other processing methods. Machine tool is an important equipment in the manufacturing industry, which can process various metal and non-metal materials.

Two, the difference between lathes and machine tools

1. Different functions: lathes are mainly used for rotary cutting in metal processing, suitable for making workpiece with smaller diameter, longer length and relatively simple shape. The machine tool is a universal processing machine that can be processed in a variety of ways, including turning, stamping, forging and so on.

2. Different uses: lathes are often used to make various precision parts, such as wheels, bearings, pistons, etc. The machine tool is mainly used for processing various mechanical parts and other various types of parts.

3. Different structure: lathe is usually composed of bed, spindle, feed mechanism, cutting tool, tail frame and other parts; The machine tool usually includes the bed, the machine tool spindle, the feeding system, the precision adjustment system, etc.

4. Different modes of operation: the lathe is a machining method that the workpiece rotates and the tool cuts the residual material along the rotation track of the workpiece; The machine tool can carry out a variety of motion modes, such as rotation, translation, tilt and so on.
