Machine tool feed system is usually driven by AC servo motor ball screw feed drive to achieve, to simplify the structure.

机床的进给系统通常是通过交流伺服电机驱动的驱动滚珠丝杠饲料，简化结构，实现。

The system of drive are all driven by stepping motors.the machine system design includes every free degrees,computation of drive and transmission system .the third and four degree of freedom are performed by the feed screw having the spline of ball bearing which is design specially for robot .with the textual study,it can be believe the user will have an overall understanding to the way of thinking and steps of the machine system.

在机械系统设计上，对每个自由度驱动、传动系统进行了计算与校核，其中第三四自由度有专为机器人设计的带滚珠花键的丝杠来实现。通过本文的学习，相信使用者会对它的机械系统设计的步骤和方法有一定的了解。

Super audio guides are hardening, the use of stepper or servo motor driven ball screw feed realize seamless exercise.

These issues include: the main axis may cause a similar problem with the main axis of the fault has affected the accuracy of bending; workpiece clamping possible problem is that the workpiece center and the main discrepancies, which could lead to instability in rotating workpiece; servo motor failure: the feed system Ball Screw bending and oil do not lead to rust long run can also be caused by poor, such as the same issues.

这些问题包括：主轴主要可能引起类似问题的故障有主轴弯曲影响精度；工件装夹方面可能的问题是工件中心和主轴不一致，由此可能导致工件转动不稳；伺服电机出现故障：进给系统中滚珠丝杠的弯曲和长时间不上油导致生锈运行不畅等也可能引起相同的问题等。

Two-way from the X-Y table driven precision CNC workpiece completed X, 2 Y direction of the movement to X, Y, Z direction of the 3 Feed Movement ball screw, by AC servo motor drive.

由X-Y双向精密数控工作台带动工件完成X， Y两个方向的进给运动；X， Y， Z三个方向的进给运动均滚珠丝杠，并由交流伺服电机驱动。

And they shall put upon it all its utensils with which they minister upon it, the firepans, the forks, and the shovels, and the basins-all the utensils of the altar; and they shall spread over it a covering of porpoise skin, and put in its poles.
