 磨床的種類很多,主要有平面磨床、外圓磨床、內圓磨床、萬能外圓磨床(也可磨內孔)、齒輪磨床、螺紋磨床,導軌磨床、無心磨床(磨外圓)和工具磨床(磨刀具)等。下面小編主要介紹下磨床的結構:
 
    (1)砂輪架——安裝砂輪并帶動砂輪作高速旋轉,砂輪架可沿滑座的燕尾導軌作手動或液動的橫向間隙運動。 
 
    (2)滑座——安裝砂輪架并帶動砂輪架沿立柱導軌作上下運動。 
 
    (3)立柱——支承滑座及砂輪架。 
 
    (4)工作臺——安裝工件并由液壓系統驅動作往復直線運動。 
 
    (5)床身——支承工作臺、安裝其它部件。 
 
    (6)冷卻液系統——向磨削區提供冷卻液(皂化油)。 
 
    (7)液壓傳動系統——其組成有: 
 
    1)動力元件——為油泵,供給液壓傳動系統壓力油; 
 
    2)執行元件——為油缸,帶動工作臺等部件運動; 
 
    3)控制元件——為各種閥,控制壓力、速度、方向等 
 
    4)輔助元件——如油箱、壓力表等。 
 
    液壓傳動與機械傳動相比具有傳動平穩,能過載保護,可以在較大范圍實現無級調速等優點。 
磨床的七個優勢: 
 
一、加工零件精度高、質量安穩 
 
    平面磨床的定位精度和重復定位精度都很高,較容易保證一批零件尺度的一致性,只需工藝規劃和程序正確合理,加之精心操作,就可以保證零件取得較高的加工精度,也便于對加工進程實行質量操控。 
 
二、自動化程度高,可以減輕操作者的體力勞動強度 
 
    平面磨床加工進程是按輸入的程序自動完結的,操作者只需起始對刀、電火花切割機裝卸工件、替換刀具,在加工進程中,主要是觀察和監督機床運轉。 
 
三、尺度標注應契合平面磨床加工的特色 
 
    在數控編程中,所有點、線、面的尺度和方位都是以編程原點為基準的。因此零件圖上直接給出坐標尺度,或盡量以同一基準引注尺度。 
 
四、一致幾許類型或尺度 
 
    零件的外形、內腔采用一致的幾許類型或尺度,這樣可以削減換刀次數,還可能應用操控程序或專用程序以縮短程序長度。零件的形狀盡可能對稱,便于利用平面磨的鏡向加工功能來編程,以節約編程時間。 
五、定位基準可靠 
 
    在平面磨床加工中,加工工序往往較會集,以同一基準定位十分重要。便于新產品研發和改型。平面磨床加工一般不需要很多復雜的工藝裝備,經過編制加工程序就可把形狀復雜和精度要求較高的零件加工出來,當產品改型,更改規劃時,只需改變程序,而不需要重新規劃工裝。所以,平面磨床加工能大大縮短產品研發周期,為新產品的研發開發、產品的改善、改型供給了捷徑。 
六、可向更高級的制造體系發展 
 
    平面磨及其加工技術是計算機輔助制造的根底。 
 
七、生產效率高 
 
    平面磨床加工是能再一次裝夾中加工多個加工表面,一般只檢測首件,所以可以省去普通機床加工時的不少中心工序,并且因為磨床加工出的零件質量安穩,為后續工序帶來便利,其綜合效率明顯提高。
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.
