The fault on the tool post may be due to the breakdown of machinery,electrical as well as control system.

0引言TDNC150A数控车床属台式数控车床，体积轻巧、结构紧凑，装有四工位自动回转刀架，使用WA-21S数控系统；它是典型的由单片机和步进电机组成的经济型数控车床，由于其价格低、适应性好，常常用于教学和普通零件加工；它的刀架结构是蜗杆蜗轮式，能够独立控制，要使其正常工作，涉及到机械、电气、控制系统等的稳定可靠工作。

This paper elaborates,in the lathe numerical control system GSK 996T,under the condition of guarantee of cutting accuracy,how reasonable use of the tool is made by setting proceed complex components repeatedly when there is no four-way tool post in machine tool body,i.

本文阐述了在GSK996T车床数控系统中，当机床本体没有四方刀架，即只有排刀架时，在保证切削精度的前提下，如何利用多次对刀对复杂零件进行合理加工。

From the tool carrier with the design principle, only two will be able to support the claw, as a result of cutting tools to the workpiece resistance F'r, so that the work put in to live with the tool carrier on the two supporting legs.

从跟刀架的设计原理来看，只需两只支承爪就可以了，因车刀给工件的切削抗力F'r，使工件贴住在跟刀架的两个支承爪上。

By turning slender shaft with the tool easy to have a "bamboo-shaped", mainly due to claw card with the tool carrier on the work pressure.

用跟刀架车削细长轴容易产生&竹节形&，主要原因是跟刀架卡爪对工件压力过大造成的。

In the left tool carriage, the ball leadscrew、the servo motor and single gear reducer were displaced,and the coordinated movement about X and Z axis could be implemented by semi-closed loop control of SINUERRIK 802D numerical system.

左刀架采用滚珠丝杠、伺服电机和一级齿轮减速，并利用SINUMERIK 802D数控系统的半闭环控制实现左刀架的X轴和Z轴联动控制，机床改造后，大大扩大了机床的加工范围，同时提高了生产效率和加工精度。

Like the Trunk rack and the Spare Tire Rack when your bikes are on the rack it is often hard to get into the back of the car.

像架干线和备用轮胎架当你的自行车在机架上往往是很难进入的车后座。

The utility model belongs to a massage body-building device, composed of a grip, a grip connecting piece, a tension spring, a roller connecting piece, a roller carrier and a roller, wherein, two connecting plates on the roller carrier and the roller are respectively connected and fixed by a connecting shaft, the roller whose surface is smooth is cylindrical, a connecting piece of the roller carrier is made by gripping round steel into a circular hole, and after two ends of the connecting piece of the roller carrier, which is connected with the connecting plates, are pressed into a flat shape, a drilling hole and the connecting plates are connected and fixed by the connecting shaft.

本实用新型属于按摩健身器，是由握把、握把连接件、拉簧、滚轮连接件、滚轮架及滚轮组成，其特点是：滚轮架上的两个连接板及滚轮均有连接轴连接固定；滚轮为圆柱形，其表面呈光滑；滚轮架连接件由圆钢握成圆孔，同连接板连接的两端压成扁形后钻孔与连接板由连接轴连接固定。

The main difficulty in maintaining the low-flying, right before the target stopped before there are some mountains, trees also more than the flying height, waiting for the alarm, flying low over the tree would die a hurry, here is a pattern even distracted skills tree from the woods and trees around the gap between the wearing, wearing a back end, failed several times, the requirements of high technology is,豁出去later, and is not even a few fighter planes like you play, the beginning fly, warning a short while, and soon the hills, two aircraft from put a red 4 missiles, missile thought more terrible, the result was even easy to flash, I saw a missile fly in front of the explosion really fun, in fact, the missile is a good hide, and more attention after the perspective to observe the missile position, when the missile away from you, almost 100 distance of 100 -200 m,(their estimate of the distance from there anyway) who has risen sharply and optional, you can play to stimulate the rapid decline in almost a sudden sharp rise in the ground, of course, elections are the rapid turn right turn left, air giant slalom, flip aircraft line, multi-练练, the computer is the point of missile小意思, nothing after playing air combat, interesting ah ~~~~ even the highest record was 28 to avoid a meeting, including surface-to-air missiles, the computer told me to fly by the tail I am thrown to the ground the trees the mountains 11 miles or a word and the computer novice and more air play than the simple low wear and more trees to the

难度主要在保持低空飞行，快到目标前有一些高山挡住，树还特别多，飞的比树高，等着报警把，飞的比树低想死着急，这里偶愣是用花样技巧，从树林里树与树的缝隙之间穿了过来，最后又穿了回去，失败几次，要求技术实在是高，后来豁出去了，不就是几架战斗机偶就跟你们玩玩，一开始就高飞，不一会报警了，快到山头， 2架飞机冲过来放了4导弹，原以为导弹多可怕，结果，被偶轻松闪过，看见导弹飞到我前面爆炸真好玩，其实导弹是很好躲的，注意多用后视角，观察导弹位置，当导弹离你差不多100-200米百距离，(自己估计的反正有段距离)可选者急速上升，还可以玩刺激急速下降快到地面时突然急速上升，当然选者急速右转左转，空中大回转，翻转飞机都行，多练练，电脑那点导弹完全是小意思，以后没事耍空战，有意思啊~~~~偶最高纪录是1次避了28枚导弹包括地对空，电脑跟我机尾飞被我甩在地上山上树上海里11次总之新手还是和电脑多玩玩空战比起超低空穿树简单的多的去了

Two of our wheels are driven by rotating power system to made the cylinder rotate . The swinging rack is driven by a set of crankshaft swinging bar which is mounted on the frame and the swinging rack is supported on the frame.

在四个支撑滚轮中，其中两个传动轮由转动动力系统拖动使转筒产生转动；摆动架由一组曲柄摆杆机构来驱动，曲柄摆杆机构装在机架上，摆动架由轴承组件支撑在机架上。
