　　Main parameters to be noticed in the selection of guide screw? The ball pressure inside the screw can strengthen the rigidity of the screw mother when it is used in mechanical installation. What main parameters should be noticed in the selection process of the ball screw? Let's look at it in detail.

　　1、公称直径。也就是丝杠的外径，常见的规格有很多，但是很多厂家准备的规格并不齐全，所以选择直径时要多留意下。

　　1. Nominal diameter. That is, the outer diameter of the lead screw, there are many common specifications, but many manufacturers are not ready for the specifications, so when choosing the diameter, we should pay more attention to it.

　　2、螺母方式。丝杠有很多螺母方式，型号中的前几个字母表示螺母方式，在装置尺寸和性能允许的状况下，倡议大家选择常规方式。

　　2. Nut mode. There are many nuts for the screw. The first letters in the model represent the nuts. If the size and performance of the device permit, it is advisable that you choose the conventional way.

　　3、导程。简单来说就是螺距，螺杆每旋转一周螺母直线运动的间隔，导程是与直线速度有关系的，在输入转速一定的状况下，导程越大速度越快。

　　3. Guide. Simply speaking, the pitch of the screw is the interval between the straight-line movement of the nut in each rotation cycle. The lead is related to the straight-line speed. Under the condition of a certain input speed, the larger the lead, the faster the speed.

　　选择适宜的导轨丝杠参数，丝杠才干发挥作用，也能保证加工质量，后期我们会给大家继续引见滚珠丝杠相关内容，欢送继续关注http://tianboo.net。

　　Choose the appropriate parameters of guide screw, lead screw can play a role, but also ensure the quality of processing. Later we will continue to introduce the ball screw related content, welcome to continue to pay attention to http://tianboo.net.
