溫州米勒流體設(shè)備科技有限公司衛(wèi)生級(jí)不銹鋼常壓人孔的常用拋光方法有以下幾種
1、磁研磨拋光 磁研磨拋光是利用磁性磨料在磁場(chǎng)作用下形成磨料刷對(duì)工件磨削加工。這種方法加工效率高質(zhì)量好加工條件容易控制
工作條件好。采用合適的磨料表面粗糙度可以達(dá)到Ra0.1μm。
The Wenzhou Miller Fluid Equipment Technology Co., Ltd. Sanitary stainless steel atmospheric manhole common polishing methods following
1, magnetic polishing magnetic polishing is formed under the magnetic field magnetic abrasive the abrasive brush workpiece grinding. Processing efficiency of this method is high good quality and easy to control the processing conditions
Good working conditions. Appropriate abrasive the surface roughness can be achieved Ra0.1μm.
2、流體拋光 流體拋光是依靠高速流動(dòng)的液體及其攜帶的磨粒沖刷工件表面達(dá)到拋光的目的。常用方法有磨料噴射加工、液體噴射加工不銹鋼常壓人孔拋光。
、流體動(dòng)力研磨等。流體動(dòng)力研磨是由液壓驅(qū)動(dòng)使攜帶磨粒的液體介質(zhì)高速往復(fù)流過(guò)工件表面。介質(zhì)主要采用在較低壓力下流過(guò)性好的特

, Fluid power, such as polishing. Grinding by means of fluid power to flow through the surface of the workpiece to carry the abrasive particles in the liquid medium is driven by hydraulic speed reciprocating. The medium is mainly used at a lower pressure downstream good Laid
The special compound the polymer-like substance doped abrasive made of the abrasive silicon carbide powder can be used.
3、超聲波拋光 將不銹鋼常壓人孔工件放入磨料懸浮液中并一起置于超聲波場(chǎng)中依靠超聲波的振蕩作用使磨料在工件表面磨削拋光。超聲波加工宏觀力
小不會(huì)引起工件變形但工裝制作和安裝較困難。超聲波加工可以與化學(xué)或電化學(xué)方法結(jié)合。在溶液腐蝕、電解的基礎(chǔ)上再施加超聲波
振動(dòng)攪拌溶液使工件表面溶解產(chǎn)物脫離表面附近的腐蝕或電解質(zhì)均勻超聲波在液體中的空化作用還能夠抑制腐蝕過(guò)程利于表面光亮

4、不銹鋼常壓人孔電化學(xué)拋光過(guò)程分為兩步：
1、宏觀整平 溶解產(chǎn)物向電解液中擴(kuò)散材料表面幾何粗糙下降Ra1μm。
2、微光平整 陽(yáng)極極化表面光亮度提高Ra1μm。 電解拋光 電解拋光基本原理與化學(xué)拋光相同即靠選擇性的溶解材料表面微小凸
不銹鋼常壓人孔出部分使表面光滑。與化學(xué)拋光相比可以消除陰極反應(yīng)的影響?yīng)バЧ^好。
5、機(jī)械拋光 機(jī)械拋光是靠切削、材料表面塑性變形去掉被拋光后的凸部而得到平滑面的拋光方法一般使用油石條、羊毛輪、砂紙等以
不銹鋼常壓人孔手工操作為主特殊零件如回轉(zhuǎn)體表面可使用轉(zhuǎn)臺(tái)等輔助工具表面質(zhì)量 要求高的可采用超精研拋的方法。超精研拋是采用特制的磨具
在含有磨料的研拋液中緊壓在工件被加工表面上作高速旋轉(zhuǎn)運(yùn)動(dòng)。利用該技術(shù)可以達(dá)到Ra0.006μm的表面粗糙度是各種拋光方法中
最高的。光學(xué)鏡片模具常采用這種方法。這種方法目前是國(guó)內(nèi)外最常見(jiàn)的方法，溫州米勒流體設(shè)備科技有限公司也是采用這種方法。主要優(yōu)
點(diǎn)在于光潔度可以很好的控制，達(dá)到高難度要求。
6、化學(xué)拋光 不銹鋼常壓人孔化學(xué)拋光是讓材料在化學(xué)介質(zhì)中表面微觀凸出的部分較凹部分優(yōu)先溶解從而得到平滑面。這種方法的主要優(yōu)點(diǎn)是不需復(fù)雜設(shè)

6, chemical polishing of stainless steel atmospheric pressure the manhole chemical polishing is more concave part of the surface microstructure protruding part of the material in the chemical medium priority dissolved resulting smooth surface. The main advantage of this method does not require complicated set
You can prepare polishing the complex shape of the workpiece polished workpiece efficiency. Chemical polishing the core problem is the preparation of the polishing liquid. The surface roughness is generally obtained by the chemical polishing
Number of 10μm.
