JB/T 3317.3-2011

Designers, process engineers, and procurement staff in machinery manufacturing use this standard to select and specify the types and parameters of multi-tool chucking lathes. It standardizes the series composition and dimensions, ensuring consistency and interchangeability of equipment. This is critical for improving production efficiency and maintaining machining accuracy.

机械制造企业的设计人员、工艺人员和采购人员使用本标准，用于选择和设计卡盘多刀车床的型号与规格。该标准统一了机床的系列构成和参数，确保设备选型的一致性和互换性，对提高生产效率和保证加工精度至关重要。

This standard specifies the series composition, application and performance, varieties, and parameters of multi-tool chucking lathes, applicable to newly designed machines with a maximum turning diameter on the tool post from 80 mm to 500 mm. It defines six series: basic, simplified, copying, turret, CNC, and twin-spindle, detailing their intended uses, performance characteristics, and accuracy requirements. Parameter tables provide key specifications such as maximum turning length, spindle nose dimensions, tool section height, main motor power, spindle speed, and feed rate for various sizes, offering a unified basis for machine design and selection.

本标准规定了卡盘多刀车床的系列构成、用途及性能、品种和参数，适用于刀架上最大车削直径80mm至500mm的新设计机床。标准定义了基型、简易、仿形、转塔、数控和双轴六种系列，并给出了各系列的用途、性能特征和精度要求。参数表列出了不同规格机床的最大车削长度、主轴端部尺寸、刀具截面高度、主电动机功率、主轴转速和进给量等关键参数，为机床设计和选型提供了统一依据。
