机床

Therefore a manufacturing factory in a medium turnery is usually used for Labor of mechanical processing of a part of the container kind, and it accounts for 15%~20% of the processing amount of the whole product approximately.

因此，一般中型机床制造厂用于箱体类零件的机械加工劳动量约占整个产品加工量的15%～20%。

There are many machine shops which have inserted a brush of the right configuration on their turret lathe and used it as their final operation for cleaning, deburring, or finishing.

许多机械工厂的机床用合适的刷子来完成清洁修整、打磨修边的工作。

The main components of the lathe are the headstock and tailstock at the oppoaite ends of a bed,and a tool-post between them which holds the cutting tool.the tool-post stands on a cross-side which enblesit to move sidewards across the saddle or carriage as well as along it,depending on the kind of job it is doing.the ordinary centre lathe can accommodat only one tool at at time on tool-post,but a turret lathe is capable of holding five or more tools on the revolving tueeet.

刀架位于一个纵面板上，小拖板使刀架能够根据加工操作的不同作纵向移动；同时又随大拖板作横向移动。普通顶尖车床只能在刀架上夹持一件刃具，但六角车床可以在其旋转的六角刀架上夹持五件或更多的刃具。车床的床身必须很牢固结实以避免在受力的时候弯曲和变形。请提问的同学最好参观一下工厂的金属切削/机加工车间。那里有车床，还有其他种类的金属切削机床。

They are advocates of green environmental protection energy-saving power supply, has been formed are: crystal-like medium, high, ultra-high frequency induction heating machine, high frequency quenching machine, high-frequency annealing machine, IF forging furnace, medium frequency melting furnace, high-frequency brazing welding machine, such as a series of high-tech products.

他们正在倡导绿色环保节能电源，目前已形成有：晶体式的中、高、超高频感应加热机，高频淬火机床，高频退火机，中频锻造炉，中频熔炼炉，高频钎焊机等一系列的高新技术产品。

The newly built precision workshop has the capacity to produce high-speed precision low-noise bearings which are used in precision machines such as the main shaft of machine tools, large/medium motors and precision rolling mills, so as to substitute imported ones or make up domestic underproduction, which saves the cost for customers, shorten the receipt period and contributes to the industry development and technical advance.

新建成的精密车间可生产高速精密、低噪音轴承用于机床主轴、中大型电机、精密轧机等精密机械上，以替代进口或补充国内生产不足，为用户节约成本，减少进货周期，为产业发展和技术进步做出了贡献。

It is shown that the most unstable period of machine tool is the period of starting and there exists the so-called starting undershoot phenomenon.

所以，在研抛加工中，如果避开机床的起动阶段，就可以达到稳定加工过程的目的。

The greatest advantage in CNC machining comes from the unerring and rapid positioning movements possible.

CNC机床的最大优势来自无错的和快速的可能运动的控制。

NC simulation software is applied in numerical controlled experiment,it has enhanced the unideal results and low efficiency of the experimental sector in the teaching of numerical controlled course.

在数控实验中，数控仿真软件的应用，改善了目前数控技术课程教学中实验环节效果不理想、效率较低的现象，提高了学生数控编程能力、数控机床的操作能力及系统的维护能力

A method to develop a reciprocating translation with uniform moving velocity was provided.

在某些机床中，往复运动基本上是用曲柄摇杆机构或曲柄导杆来实现的。

Then, the universal CNC class is established using the thoughts of O-O technology and the models of send process, receive process and remote process is expressed by UML language.

提出了针对串行通信数控机床构建局域网式DNC通信结构的技术方案，即基于以太网的DNC通信技术。

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
