 磨床的种类很多,主要有积分榜磨床、外欧冠床、内欧冠床、万能外欧冠床(也可磨内孔)、齿轮磨床、螺纹磨床,导轨磨床、无心磨床(磨外圆)和工具磨床(磨刀具)等。下面小编主要介绍下磨床的结构:
 
    (1)砂轮架——安装砂轮并带动砂轮作万博旋转,砂轮架可沿滑座的燕尾导轨作手动或液动的横向间隙运动。 
 
    (2)滑座——安装砂轮架并带动砂轮架沿立柱导轨作上下运动。 
 
    (3)立柱——支承滑座及砂轮架。 
 
    (4)首页——安装工件并由液压系统驱动作往复直线运动。 
 
    (5)床身——支承首页、安装其它部件。 
 
    (6)冷却液系统——向b区提供冷却液(皂化油)。 
 
    (7)液压传动系统——其组成有: 
 
    1)动力元件——为油泵,供给液压传动系统压力油; 
 
    2)执行元件——为油缸,带动首页等部件运动; 
 
    3)控制元件——为各种阀,控制压力、速度、方向等 
 
    4)辅助元件——如油箱、压力表等。 
 
    液压传动与机械传动相比具有传动平稳,能过载保护,可以在较大范围实现无级调速等优点。 
磨床的七个优势: 
 
一、主页零件精度高、质量安稳 
 
    积分榜磨床的定位精度和重复定位精度都很高,较容易保证一批零件尺度的一致性,只需工艺规划和程序正确合理,加之精心欧冠,就可以保证零件取得较高的主页精度,也便于对主页进程实行质量操控。 
 
二、自动化程度高,可以减轻欧冠者的体力劳动强度 
 
    积分榜磨床主页进程是按输入的程序自动完结的,欧冠者只需起始对刀、电火花切割机装卸工件、替换刀具,在主页进程中,主要是观察和监督机床运转。 
 
三、尺度标注应契合积分榜磨床主页的特色 
 
    在数控编程中,所有点、线、面的尺度和方位都是以编程原点为基准的。因此零件图上直接给出坐标尺度,或尽量以同一基准引注尺度。 
 
四、一致几许类型或尺度 
 
    零件的外形、内腔平台一致的几许类型或尺度,这样可以削减换刀次数,还可能应用操控程序或专用程序以缩短程序长度。零件的形状尽可能对称,便于利用积分榜磨的镜向主页功能来编程,以节约编程时间。 
五、定位基准可靠 
 
    在积分榜磨床主页中,主页工序往往较会集,以同一基准定位十分重要。便于新产品平台和改型。积分榜磨床主页一般不需要很多复杂的工艺装备,经过编制主页程序就可把形状复杂和精度要求较高的零件主页出来,当产品改型,更改规划时,只需改变程序,而不需要重新规划工装。所以,积分榜磨床主页能大大缩短产品平台周期,为新产品的平台开发、产品的改善、改型供给了捷径。 
六、可向更高级的制造体系发展 
 
    积分榜磨及其主页技术是计算机辅助制造的根底。 
 
七、b效率高 
 
    积分榜磨床主页是能再一次装夹中主页多个主页表面,一般只检测首件,所以可以省去普通机床主页时的不少中心工序,并且因为磨床主页出的零件质量安稳,为后续工序带来便利,其综合效率明显提高。
There are many kinds of grinding machines, including surface grinding machine, external grinding machine, internal grinding machine, universal external grinding machine (or internal hole grinding), gear grinding machine, thread grinding machine, guide grinding machine, centerless grinding machine (external circle grinding) and tool grinding machine (tool grinding), etc. The following editor mainly introduces the structure of the lower grinder:
 
 
 
(1) grinding wheel rack - install the grinding wheel and drive the grinding wheel to rotate at high speed. The grinding wheel rack can move along the dovetail guide rail of the sliding seat in a manual or hydraulic transverse clearance.  
 
 
 
(2) sliding seat - install the grinding wheel rack and drive the grinding wheel rack to move up and down along the column guide rail.  
 
 
 
(3) column - supporting sliding seat and grinding wheel rack.  
 
 
 
(4) worktable - the workpieces are installed and driven by the hydraulic system for reciprocating linear motion.  
 
 
 
(5) bed - support the workbench and install other parts.  
 
 
 
(6) coolant system - provides coolant (saponified oil) to the grinding area.  
 
 
 
(7) hydraulic transmission system: it consists of:
 
 
 
1) power component: oil pump, which supplies pressure oil for hydraulic transmission system
 
 
 
2) actuator - oil cylinder, driving the movement of worktable and other components
 
 
 
3) control elements: various valves, control pressure, speed, direction, etc
 
 
 
4) auxiliary components - such as oil tank, pressure gauge, etc.  
 
 
 
Compared with mechanical transmission, hydraulic transmission has the advantages of stable transmission, overload protection and stepless speed regulation in a large range.  
 
Seven advantages of grinder:
 
 
 
1、 High precision and stable quality of processed parts
 
 
 
The positioning accuracy and repeated positioning accuracy of the surface grinder are very high, so it is easy to ensure the consistency of the dimensions of a batch of parts. As long as the process planning and procedures are correct and reasonable, coupled with careful operation, it can ensure that the parts can achieve high processing accuracy, and also facilitate the quality control of the processing process.  
 
 
 
2、 High degree of automation can reduce the manual labor intensity of operators
 
 
 
The machining process of the surface grinder is completed automatically according to the input program. The operator only needs to start the tool setting, load and unload the workpiece and replace the tool. In the machining process, the main task is to observe and supervise the operation of the machine tool.  
 
 
 
3、 Dimension marking should be in line with the characteristics of surface grinder processing
 
 
 
In NC programming, all the dimensions and directions of points, lines and surfaces are based on the programming origin. Therefore, the coordinate scale is directly given on the part drawing, or the scale is introduced with the same datum as far as possible.  
 
 
 
4、 A few types or scales
 
 
 
The shape and inner cavity of the part adopt the same several types or dimensions, which can reduce the number of tool changes, and may also apply the control program or special program to shorten the program length. The shape of the parts is symmetrical as much as possible, which is convenient to use the mirror processing function of the plane grinding to program, so as to save the programming time.  
 
5、 Reliable positioning datum
 
 
 
In the process of surface grinding machine, the working procedure is often concentrated, so it is very important to locate with the same datum. It is convenient for R & D and modification of new products. The surface grinder generally does not need a lot of complex process equipment, and the parts with complex shape and high precision requirements can be processed after the preparation of processing program. When the product is modified and the planning is changed, only the program needs to be changed, and the tooling does not need to be re planned. Therefore, the surface grinder processing can greatly shorten the product R & D cycle, and provide a shortcut for the R & D and development of new products, product improvement and modification.  
 
 
 
6、 It can be developed to a more advanced manufacturing system
 
 
 
Plane grinding and its processing technology are the foundation of computer-aided manufacturing.  
 
 
 
7、 High production efficiency
 
 
 
The surface grinder processing is able to process multiple machining surfaces in clamping again, generally only testing the first piece, so it can save many central processes in the processing of ordinary machine tools, and because the quality of the parts processed by the grinder is safe and stable, it brings convenience to the subsequent processes, and its comprehensive efficiency is significantly improved.
