1.Engine Lathes ［1］Engine lathes，of course，are general purpose
machines used in production and maintenance shops all over the world. Sizes range from small bench models to huge heavy duty pieces of equipment. Many of the larger lathes are equipped with auxiliary parts which are not commonly available in ordinary shops，such as automatic stops for the carriage.
Text & Translation
The first screw machines were designed to feed bar stock and wire used in making small screw parts. At present，however， the turret lathe is frequently used with a collet attachment，and the automatic screw machine can be equipped with a chuck to hold castings.
Text & Translation
In the single spindle automatic screw machine，a specific length of stock is automatically fed through the spindle to a machining area. At this point，the turret and cross slide move into position and automatically perform whatever operations are required. After the machined piece is cut off，stock is again fed into the machining area and the entire cycle is repeated.

cooling system is built into the engine ． There are hollow spaces
around each engine cylinder and combustion chamber．These hollow spaces are called water jackets ， since they are filled with water．When the engine is running，the water takes heat from the engine，becoming hot in the process．A water pump pumps the
The purpose of the fan is to provide
a powerful draft of air through the radiator．The radiator is a device for
holding a large volume of water in
close contact with a large volume of

混合气的燃烧在
发动机中产生大量 的热，其中部分热 量通过废气被排出 以阻止发动机过热。 但是，残留在发动 机中的余热仍足以 使发动机受到严重 损坏，冷却系统就 是专门用来消除余 热的。冷却系统还 有一个重要任务， 就是让发动机迅速 预热，然后就让发 动机保持恒定的温 度。
