请问这个8米滚珠丝杠表的精度是多少？

数控铣床滚珠丝杠是数控铣床的重要部件之一，它是传动机构的一种，用于将电机的旋转运动转换为机床工作台的线性运动。滚珠丝杠由滚珠丝杠母和滚珠丝杠子组成，滚珠丝杠子由滚珠组成，滚珠丝杠母则是通过内螺纹与外螺纹的配合，使滚珠丝杠子在旋转时沿轴向移动，从而实现工作台的线性运动。滚珠丝杠具有精度高、刚性好、寿命长等优点，因此被广泛应用于数控铣床等高精度机床中。

这个8米滚珠丝杠表可以测量哪些尺寸范围内的物体？

8mm rolling ball screw gauge are both measuring tools used to measure the dimensions of objects. The main difference between the two is the type of mechanism used to take the measurement. The 8mm rolling ball screw gauge uses a rolling ball screw mechanism to take the measurement. This mechanism consists of a ball screw that rotates in response to a force applied to it. The rotation of the ball screw moves a gauge attached to it, allowing the user to take the measurement. On the other hand, the 8mm rolling ball screw gauge uses a micrometer mechanism to take the measurement. This mechanism consists of a spindle that moves in response to a force applied to it, and a scale that allows the user to read the measurement. Both tools are accurate and reliable, but they are used in different applications. The 8mm rolling ball screw gauge is often used in industrial settings, while the 8mm rolling ball screw gauge is commonly used in laboratory and scientific research settings.
