style="text-indent:25px">應用無心磨削法磨削工件的旋轉(zhuǎn)表面的磨床，通常指無心外圓磨床。在無心外圓磨床上，工件不用前列定心和支承，而是放在砂輪和導輪之間,由托板和導輪支承。砂輪一般裝在主軸端部,寬度大于250毫米的砂輪則裝在主軸中部,砂輪zui大寬度可達900毫米。砂輪高速旋轉(zhuǎn)進行磨削,導輪以較慢速度同向旋轉(zhuǎn)，帶動工件旋轉(zhuǎn)作圓周進給。貫穿磨削時，通過調(diào)整導輪軸線的微小傾斜角來實現(xiàn)軸向進給，適于磨削細長圓柱形工件、無中心孔的短軸和套類工件等。切入磨削時,通過導輪架或砂輪架的移動來實現(xiàn)徑向進給,適于磨削帶軸肩或凸臺的工件，以及圓錐體、球體或其他素線是曲線的工件。無心磨床的生產(chǎn)率較高，加上各種上下料裝置后易于實現(xiàn)自動化，大多用于大量生產(chǎn)，可由不很熟練的工人操作。</p><p style="text-indent:25px">鑄件的淬硬：對導軌表面進行淬火,可以提高導軌的耐磨性。用火焰粹火和感應加熱淬火二種方法,可以獲得大面積淬硬,而且硬化深度大、耐磨性高,但由于加熱面積大,溫度不易控制,導軌變形大。需重磨導軌面,影響生產(chǎn)周期。采用交流電點觸淬火的方法效果好,淬火導軌變形小,而且設(shè)備簡單、成本低,操作方便。點接觸淬火是用表面刻有波形凸紋的銅輪,以定的速度在導軌表面滾動,電流從銅輪和導軌間流過,并轉(zhuǎn)變?yōu)闊崃?使導軌表面局部加熱到相應溫度,隨著銅輪移開,加熱表面將迅速冷卻,這樣表面就形成硬化條紋。操作時條紋軌跡要封閉,否則局部地方容易磨損。硬化深度與電流大小和銅輪滾動速度有關(guān)。數(shù)控磨床工作完畢后，應將砂輪退離工件，切斷總電源，各手柄放置空位上，恢復磨床正常狀態(tài)，做好日常保養(yǎng)。</p><div

style="text-indent:25px">用光刨代磨的方法,加工達到導軌磨床的磨削要求。以加工床身長10.72m的**磨床Hl43的床身導軌為例,具體方法為第一步床身前面向下,底面對龍刨側(cè)刀架,校正零件刨底面和后面,第二步床身底面向下,前面對龍刨側(cè)刀架,校正零件刨各級臺面及沉割槽,刀具檢查面,刨前床身10°導軌面;刨后床身平V導軌面。光刨代磨達到的技術(shù)要求如下:前床身導軌與后床身導軌的水平方向的平行度允差為在1米長度上:0.015mm,在全長上0.10mm,在垂直方向的平行度允差為1米長度上:0.02mm;在全長上010mm。后床身導軌在垂直平面內(nèi)的直線度允差為在1米長度上0.01mm,在全長上:0.10mm;在水平平面內(nèi)的直線度允差為在1米長度上:0.01mm在全長上:0.10m,兩導軌面間的平行度(即扭曲)允差為在1米長度上0.02/1000,在全長上0.10/1000。要達到上述要求,首先要調(diào)整龍門刨床床身的平直度精度,用吸鐵拷表吸在龍刨刀架上,校正加工零件的平直度并保證在距二端點2m(全長2/9)二點水平高度相同,然后在零件二端用樁頭支緊,用三個以上的壓板壓緊。磨床的加工余量小生產(chǎn)效率高，加工精度高，表面質(zhì)量好。江蘇小型外圓磨床</p><p style="text-indent:25px">磨床的種類有很多，對于磨床的選購者來說一定要根據(jù)自己的實際情況來考量。河北無芯磨床價格表</p><p style="text-indent:25px">零件的工藝分析是了解零件的形狀、尺寸、材料、重量、技術(shù)要求、批量,然后確定零件的加工方法加工余量、定位基面、裝夾方法。不同的零件形狀和要求,可以采用不同的加工方法,而每道工序可由不同的機床來加工,也可用相同的機床來加工,同種零件也有各種不同的加工方法。在磨床的加工制造中,外圓磨床的下工作臺、大型外圓磨床的床身等均屬于撓性零件,由于零件是撓性的,在加工過程中,安裝條件不同時,加工后零件的幾何精度,必然會引起變化,掌握零件加工的臨床精度與其在實際使用安裝條件下精度的變化規(guī)律就成為保證撓性零件加工質(zhì)量的關(guān)鍵。因此在加工過程中,必須正確地裝夾這類撓性零件。河北無芯磨床價格表</p></p><br
