跟刀架

Methods The reverse feeding turning is used, and a series of effective measures are taken, such as selecting optimum tool parameter and cutting allowance, using a stretching apparatus and an axle sleeve follow-rest.

采用反向进给车削，配合以最佳的刀具几何参数、切削用量、拉紧装置和轴套式跟刀架等一系列有效措施。

Should be a reasonable choice of tool carrier with the structure of the right bearing block Globoidal grinding to a good contact with the workpiece.

应合理选用跟刀架结构，正确修磨支承块弧面，使其与工件良好接触。

In addition to the pad with the installation tool, the workpiece can be based on length of the workpiece in the following of mats equidistant not put pieces of wood (cutting in with the check in with the release, the extension units to ensure normal feeding), pieces of wood directly on the bed pad The thickness of the body in order to be able to firm up slightly better job, made of wood semi-circular pit, run-time increase in lubricating oil.

垫块 除跟刀架装置外，还可根据工件长度，在工件下面垫放不等距的木块(在切削中随放随取，保证拖板正常进给)，木块直接垫放在床身上其厚度以能轻微托牢工件为宜，木块制成半圆弧凹坑，运行时加机油润滑。

Weifang, Shandong Center for non-standard aircraft factory in Shandong are the sole production center rack of the enterprise, wholesale and retail dealers throughout the Recruitment C616, C632, CA6140, CD6140, CDZ6140, CD6140, C620, CA6150, CDZ6150, CA6250, CDZ6250, C630, 6163,6180 Center for various models of aircraft, with the turret, the production of 100,125,160 dividing head top Z32 drill pipe.

山东潍坊非标中心架厂是山东独家生产中心架的企业，诚招各地经销商批发零售C616、C632、CA6140、CD6140、CDZ6140、CD6140、C620、CA6150、CDZ6150、CA6250、CDZ6250、C630、6163、6180各种型号中心架、跟刀架，生产100、125、160分度头顶尖Z32钻杆。

To explore the mechanism of the follower rest,a united model is developed to simulate the formation of the diameter error of the slender bar.

为探索跟刀架的作用机理，开发了一个联合模型用以仿真细长轴车削尺寸误差的形成过程。

In order to reached the requirements of precision machining,in machining process must use follower rest、flexible active thimble、space block and bracket etc fixture and assistive device. According to may appear problem on machining process, must do some with follower rest, tailstock for further improvement.

为了达到所要求的加工精度，加工过程中要使用跟刀架、弹性活络顶尖、垫块和托架等夹具和辅具，针对加工过程可能出现的问题对普通跟刀架、尾座进行改进。

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。
