The jaws of most lathe chucks can be reversed to switch form external to internal chucking.Jaws may be adapted to fit workpiece shapes that are not round.The means of attaching a lathe chuck to different machine tools have been well standardized,so that chuks made by different manufacturers can be easily interchanged.
In addition to their standard jaws,lathe chuks may also be fitted with a variety of special purpose jaws to accommodate different types of workpiece surfaces and configurations.The principal types of chuck jaws used for these purposes are called softjaws and are generally made of cast aluminum.
大多数车床夹头的下巴可以扭转转形式的外来内部chucking.Jaws可能会进行调整，以适应工件形状不属于附加车床夹头不同机床round.The手段已得到很好的标准化，使夹头了不同制造商可以很容易地互换。
除了他们的标准下巴，车床夹头也可能与颌骨的特殊用途，以适应各种安装不同类型的工件表面和用于这些目的夹头颌骨configurations.The主要类型称为softjaws，一般的铸铝制造。
尝试翻译一下哈
The jaws of most lathe chucks can be reversed to switch form external to internal chucking.
大多数机床卡盘的啮合机件（是虎钳口吗）能够反转，从外卡具转换成内卡具。
Jaws may be adapted to fit workpiece shapes that are not round. 虎钳口能够调整来适应非圆形工件的形状。
The means of attaching a lathe chuck to different machine tools have been well standardized,so that chuks made by different manufacturers can be easily interchanged.
车床卡具配置不同机器母床的方法是定好型的，因此，不同生产厂商生产的卡具都能很容易的互换。
In addition to their standard jaws,lathe chuks may also be fitted with a variety of special purpose jaws to accommodate different types of workpiece surfaces and configurations.
除了标准的虎钳口，车床卡具也可以与用于特殊目的的各种各样的虎钳口相配备，以适应不同类型的工件表面和外形的要求。
The principal types of chuck jaws used for these purposes are called softjaws and are generally made of cast aluminum.
用于这种目的的卡具虎钳口的主要类型被叫做软虎钳口，一般用生铝制成。
