GB/T 19362.1-2003 in English

《GB/T 19362.1-2003龙门铣床检验条件 精度检验 第1部分:固定式龙门铣床》由TC22（全国金属切削机床标准化技术委员会）归口，TC22SC2（全国金属切削机床标准化技术委员会铣床分会）执行，主管部门为中国机械工业联合会。
GB/T19362的本部分规定了一般用途和普通精度的固定式龙门铣床的几何精度、工作精度和轴线定位精度检验以及相应的公差。本部分适用于工作台移动且双立柱固定的龙门铣床。不适用于单柱及工作台固定和立柱移动的龙门铣床。
本部分仅用于机床的精度检验，不适用于机床的运转检查（如振动、不正常的噪声、运动部件的爬行等），也不适用于机床的参数检查（如速度、进给量等）。这些检查应在精度检验前进行。

Scope

This part of GB/T 19362 specifies the geometric accuracy, working accuracy and axis positioning accuracy inspection and corresponding tolerances of general-purpose and ordinary-precision stationary gantry milling machines. This section applies to gantry milling machines with movable worktables and fixed double columns. It is not suitable for single-column and gantry milling machines with fixed worktable and movable column. This part is only used for the accuracy inspection of the machine tool, not for the operation inspection of the machine tool (such as vibration, abnormal noise, crawling of moving parts, etc.), nor for the parameter inspection of the machine tool (such as speed, feed rate, etc.) . These checks should be performed prior to the accuracy test. This part gives the terminology of the main components of the machine tool, and names the axis according to JB/T 3051-1999.
