Modern rolling mill running with heavy-duty and high-speed, due to resolve rolling mill roller bearing longevity shortenning and burning problem,against the traditional thoughts of "random phenomenon" and "offsetting roll system position", the new thoughts of relation between rolling mill 1mm~1um micro-dimensional behavior and load characteristic of rolling mill roller bearing and screw-down drive thread pair, is developed.

现代轧机在重载、高速运行中，对轧机设计理论无法解决的轧机滚动轴承短寿烧损难题，挑战&随机现象&和&偏移距辊系定位&学术成见，开辟了探索轧机辊系1mm～1μm微尺度行为与轧机滚动轴承和压下传动螺纹副承载特性有关的新思路与方法。

These induced in transitional zone piercement of drill pipe and many screw thread failures of tool joint.

塔里木油田山前构造带地质结构复杂，同时强化钻井技术在塔里木油田得到应用，使得钻具在井下的使用环境恶劣，钻具工况复杂，导致塔里木油田钻杆加厚过渡带刺漏和钻具螺纹失效事故较多。

Feed system uses open-loop control, stepper motor driven by the slowdown after the ball screw. driven Tool for horizontal and vertical movement; After transformation, the introduction of automatic lathe transfer Tool for automatic tool change function; To achieve automatic screw machining, in the original round of the initiative pegged to the installation of the axis of photoelectric pulse generator.

进给系统采用开环控制，由步进电机经减速后驱动滚珠丝杠，带动刀架进行横向和纵向运动；改造后的车床采用自动转位刀架实现自动换刀功能；为了实现自动螺纹切削加工，在原挂轮主动轴处安装了光电脉冲发生器。

Such as the processing center in NC, CNC machine tools, such as general machine tools used in manufacturing processing professional Cylindrical turning tools, boring holes in the knife, cut, cut trough knives, screw Turning, boring tool, cutter and milling cutter,- Processing tools, super-hard campaign tool.

如在加工中心NC、数控机床，普通机床等制造加工专业用的外圆车刀、内孔镗刀、切断、切槽刀具、螺纹车削刀具、镗削刀具系统、铣刀、立铣刀、孔加工刀具、超硬系列刀具等。

In other words, there is a clearance between the top of the screw threads and the barrel surface.

换句话说，是一个关在顶尖高手之间的螺纹和桶表面。

The characters and factors were analyzed when the laser probe measurement was used in inside screw surface.

分析了激光光针扫描在测量内螺纹曲面时的特性及影响精度的因素。

Screw pump the working principle is: screw pump work, the liquid after being inhaled into the screw pump shell and sealed by Wai space, when the initiative screw rotation, the screw pump seal volume in the squeezed increase Luoya Screw pump pressure, and along the axial movement.

螺杆泵的工作原理是：螺杆泵工作时，液体被吸入后就进入螺纹与泵壳所围的密封空间，当主动螺杆旋转时，螺杆泵密封容积在螺牙的挤压下提高螺杆泵压力，并沿轴向移动。

Objective:To compare the clinical effect between cement screw post and glassfiber post applied in the instant restoration of anterior teeth.

R782B1005-2720（2009）04-0015-02目的：比较螺纹桩与纤维桩在前牙即刻修复中的临床效果。

Results:With 2 years following study,in the cement screw post group 50 of total 57 teeth were good, 2 teeth failed for root fracture、2 teeth failed for post fracture、3 tooth failed for crown loose .The rate of success is 87.72％.

结果：随访两年，其中使用螺纹桩修复57例，良好50例，松动脱落3例，钉折断2例，患牙根折2例，成功率为87.72％。
