Scope
This part of JB/T 8483 specifies the inspection methods and corresponding tolerances for geometric accuracy and working accuracy of general-purpose ordinary-grade versatile lathes. This part applies to versatile lathes with maximum swing diameter over bed of 250 mm to 400 mm and maximum workpiece length up to 1 000 mm. This part applies only to the accuracy inspection of the machine tool, and does not apply to the running inspection of the machine tool (such as vibration, abnormal noise, creeping of moving parts, etc.), or the parameter inspection of the machine tool (such as speed, feed rate, etc.). These inspections should be carried out before the accuracy inspection.
JB/T 8483 的本部分规定了一般用途的普通级精度多用车床的几何精度、工作精度的检验方法以及相应的公差。本部分适用于床身上最大回转直径250 mm～400 mm、最大工件长度至1 000 mm 的多用车床。本部分仅适用于机床的精度检验，不适用于机床的运转检查（如振动、非正常的噪声、运动部件的爬行等），或机床的参数检验（如速度、进给量等）。这些检验应在精度检验前进行。
