杠

"Please don't grudge anyone for what happened," celia said to her father, she gulped her water,"it was my fault for missing the bar."

&请不要 8 Tt t 8。 com 发生的事情怨恨任何 dd dtt。 com 人，&西莉亚对父亲说。她咽下几口水。&没有抓住杠，是我自己的过错。&

The following areas: design of transmission of the table, mainly the use of ball screws; the overall structure of the design table to understand the strengths and weaknesses, take full account of the principal contradiction, merit-based selection; control system design, its applications become more familiar with the Stepper motor-driven feed location can be accurate but the drawback is the lack of output power, so consider the source of the hydraulic motor as the driving force and the stepper motor drive system into the compound, hydraulic feeding Although it is impossible to locate, but with high output power, the two complement each other, so that accurate feed motion can be stable.

有以下几个方面：工作台的传动机构设计，主要是滚珠丝杠的运用；工作台整体结构的设计，了解优缺点，充分考虑主要矛盾，择优选取；控制系统的设计，进一步熟悉其应用步进电机驱动进给可以进行准确的定位但有个缺点就是输出力不足，所以考虑将液压电机作为动力源与步进电机驱动进给系统复合，液压进给虽然无法进行定位，但具有高输出力，二者优势互补，使进给运动可以准确稳定的进行。

Both numerical control induction machine tool X-Z axis and slew workbench of part drive by numerical contral, the coil feed motion is drived with servo motor which joins to ball screw assemblly to carry out.

数控感应淬火机床X-Z轴和工件的回转工作台均采用数控驱动，感应头的进给运动通过伺服电机带动滚珠丝杠来实现。

The output end of the gear box is connected to the feed rod and lead screw.

一台典型的车床的主轴每旋转一圈，通过光杠可以获得从0。

It is connected to both the feed rod and the lead screw and enables selecting a variety of feeds easily and rapidly by simply shifting the appropriate levers.

它是连接到了饲料杆和丝杠，使选择不同的饲料容易和迅速，只需把相应的杠杆。

Independent leadscrew and feed rod.

独立丝杠和饲料杆。

Thus, through this gear train, leading from the spindle to the quick-change gear box, thence to the lead screw and feed rod, and then to the carriage, the cutting tool can be made to move a specific distance, either longitudinally or transversely, for each revolution of the spindle.

叩2到0.118英寸尺寸范围内的48种进给量；而使用丝杠可以车削从1.5到92牙／英寸范围内的48种不同螺纹。

In this paper, the authors refer to problems about high-speed of ball screw feed system in high-speed machining, and introduce some important problems in details.

本文指出了高速加工中滚珠丝杠进给系统高速化后所面临的一系列问题，并针对几个重要问题进行详细介绍，同时提出了改进措施。

Ball screw feed system of the bending and non-oil long run lead to poor, such as rust can also be caused by the same problem.

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。

High-speed feed may Ball screw, sport, high efficiency, small heat, so can achieve high-speed feed.

高速进给可能滚珠丝杠副由于运动效率高、发热小、所以可实现高速进给。

She gently rebuff ed him, but agreed that they could be friends

她婉言拒绝了，但同意作为朋友相处。

If in the penal farm, you were sure to be criticized.

要是在劳改农场，你等着挨绳子吧！
