Equipped with manual axial and radial feeding device . it is easy to quick feeding and backing . it is able to bevel the pipe with good cutting results and high efficiency 具有手动径向轴向进刀机构，可实现轻便灵活的手动进退刀，加工坡口质量好、效率高。
Main purpose of carbo rubber control regulating wheel , which not only drives work piece to run , but also can control in feed crossing speed during machine operation 无心调整轮主要用途除了与主轮带动工件运转外，并可在机台作业时做进刀及横送速度之控制，已达工件精度之要求。
Main purpose of carbo rubber control regulating wheel , which not only drives work piece to run , but also can control in feed crossing speed during machine operation . that achieved the precision requirement of work piece 无心调整轮主要用途除了与主轮带动工件运转外，并可在机台作业时做进刀及横送速度之控制，已达工件精度之要求。
Grinding feature is to use work piece for a slow - speed operation , and wheel spindle selects a high - speed revolution and offers a minor amount of in - feed to cooperate with mechanical spinde for forward and backward movement for finishing grinding jobs 研磨特性是利用工作物做慢速运转，而砂轮心轴采高速回转并给予微量进刀配合机械心轴前后运动完成研磨作业。
The research and test results show that single - direction mining and slope cutting in the middle of face may reduce workers ' labor , shorten the working looping time , fasten the working schedule and improve efficiency 研究和实测结果表明，在薄煤层工作面采用单向割煤、中部斜切进刀方式，不但降低了工人的劳动强度，而且减少了循环作业时间，提高了生产进度和效益。
A grinding surface is consisted of multi pillars lump . because better chips of metal wash away better during grinding process and allow more grinding fluid flow and keep the temperature low for work piece , it is suitable for larger in - feed grinding 由多片柱型块组合而成为一个研磨面，由于研磨过程排屑性较好，研磨液渗透较多，研磨工件不易发热所以适合大进刀量之研磨。
1tc series boring and facing head is besed on 1ta series boring head with special cutter disc and cutter driving devicees , it not only functions of 1ta series boring head , but also can complete endface , external , splling and corner cutting 1tc系列镗孔车端面动力头是在1ta系列镗削头基础上配置专用刀盘及进刀装置而成，除具备镗削头的镗孔功能外，还可完成车端面、车外圆、车止口、切槽、倒角等加工工序。
1tc series boring and facing head is based on 1ta series boring head with special cutter disc and cutter driving devicees , it not only functions of 1ta series boring head , but also can complete endface , external , splling and corner cutting 1tc系列镗孔车端面动力头是在1ta系列镗削头基础上配置专用刀盘及进刀装置而成，除具备镗削头的镗孔功能外，还可完成车端面、车外圆、车止口、切槽、倒角等加工工序。
At present company product has " in treasure card " table drilling machine , vertical drilling machine , tapper , get milling machine , automatic feed drilling machine , gear drilling machine , auger attack amphibious machine tool , the 8 old series such as radial drilling machine , more than 60 kinds of breed 目前公司产品有“中宝牌”台式钻床，立式钻床，攻丝机，钻铣床，自动进刀钻床，齿轮钻床，钻攻两用机床，摇臂钻床等八大系列，六十多种品种。
Secondly , this paper gives a searches process of cases . considering techniques of part , this paper provide a likelihood decision rule based on characteristic and processes direction . this rule enhances the veracity of case matching , improves the reuse of cases process 其次，研究了实例零件的相似检索算法，考虑了零件加工工艺性，提出了基于加工特征和进刀方向的相似性判定准则，同时提出了三级搜索策略，从而提高了实例匹配的准确性，增强了实例工艺的重用性。
