6、························································································································34www.bzfxw.comJB/T4373－1999前言本标准是非等效采用ISO3070–4∶1998《卧式铣镗床检验条件精度检验第4部分：带移动立柱的刨台式机床》，对JB4373—86《刨台卧式铣镗床精度》的修订。本标准与ISO3070–4∶1998主要技术差异：——将G19检验项目的名称由“镗轴

7、在其移动方向上（Z轴）的挠度”改为“镗轴移动（Z轴）的直线度”；——在G14项“工作台0°、90°、180°和270°的定位精度”检验项目中，增加了“注：本项检验仅适用于普通卧式铣镗床”等文字；——将5.10“数控轴线的定位精度和重复定位精度”的允差值作了技术性修改；——第6章“工作精度检验”，补充了直线和圆弧插补铣削精度检验和镗孔的孔距精度检验。本标准对JB4373—86的重要技术内容改变情况：——标准的适用范围扩大了，即也适用于数控卧式铣镗床。——增加了以下检验项目：a)G2立柱移动（W轴）的角度偏差；b)G4工作台移动（X轴）的角度

8、偏差；c)G6主轴箱垂直移动（Y轴）的角度偏差；d)G22滑枕移动（Z轴）对主轴箱移动（Y轴）的垂直度；e)G29~G34定位精度和重复定位精度的检验；f)P11~P13直线和圆弧插补铣削精度
