style="text-indent:25px">一般大件的材料為灰口鑄鐵,成份為石墨+珠光體或游離鐵素體。在普通鑄鐵內(nèi)加入銅、錳、鋅等合金成份,可以大幅度地提高導(dǎo)軌的耐磨性,如銅錳鑄鐵，廣州工具磨床生產(chǎn)廠家、銅磷鈦鑄鐵等。但這幾種鑄鐵成本較高。在鐵水中加入鎂或鈰使石墨在鑄造狀態(tài)成球狀結(jié)晶出來，廣州工具磨床生產(chǎn)廠家,這樣的**度鑄鐵,即球墨鑄鐵。鑄件的穩(wěn)定性,主要靠澆鑄后在砂型中緩慢均勻地冷卻下來<正確的砂型設(shè)計(jì),足夠的冷卻時(shí)間>零件是否有內(nèi)應(yīng)力或消除了內(nèi)應(yīng)力,主要取決于加工方法。只要環(huán)境、溫度是穩(wěn)定的，廣州工具磨床生產(chǎn)廠家,幾何關(guān)系將不因其周圍溫度數(shù)值的高低而受到影響。鑄件的不穩(wěn)定性實(shí)質(zhì)上是由于加工方法、彈性變形,多數(shù)性況是由于溫度變化等原因而引起的。磨床可以加工各種表面，比如說平面，內(nèi)外圓柱面，圓錐面等。廣州工具磨床生產(chǎn)廠家</p><div

style="text-indent:25px">平面磨床磨削時(shí),工件安放在帶電磁吸盤的工作臺(tái)上,適宜加工中小型鋼件或鑄鐵件的平面,磨削后工件上有剩磁,應(yīng)去磁。多件磨削時(shí)高度一致,磨削剛性好,操作方便,生產(chǎn)率高。平面磨床用于磨削各種零件的平面。根據(jù)砂輪的工作面不同,平面磨床可分為用砂輪輪緣(即圓周)進(jìn)行磨削和砂輪端面進(jìn)行磨削兩類。用砂輪輪緣磨削的平面磨床,砂輪主軸常處于水平位置:而用砂輪端面磨削的平面磨床,砂輪主軸通常為立式的。根據(jù)工作臺(tái)的形狀不同,平面磨床又可分為矩形工作臺(tái)和圓形工作臺(tái)兩類。因此,根據(jù)砂輪工作面和工作臺(tái)形狀的不同,普通平面磨床可分為4類:臥軸矩臺(tái)式平面磨床;立軸矩臺(tái)式平面磨床;臥軸圓臺(tái)式平面磨床;立軸圓臺(tái)式平面磨床。</p><p style="text-indent:25px">無心磨床磨工安全操作規(guī)程： 1．用手送磨削工件時(shí)，手離砂輪應(yīng)在50毫米以上，不要握的太緊。 2．用推料棒送料肘，要拿牢推料棒，禁止用金屬棒。 3．修正砂輪時(shí)，要慢慢進(jìn)刀，并給充分的冷卻液。 4．工件在砂輪中間歪斜時(shí)，要緊急停車。 5．磨棒料時(shí)，要求托料架與砂輪，導(dǎo)輪之間的中心成一直線。嚴(yán)禁磨彎料。 6．工件未從砂輪磨出時(shí)，不準(zhǔn)取出。手接工件時(shí)，要迅速把工件握住，停止其轉(zhuǎn)動(dòng)。 7．料架上的工件要放好，以防滾掉下來傷人。 8．安裝螺旋輪時(shí)，要戴手套。拿螺旋輪的端面內(nèi)孔，不準(zhǔn)拿螺旋輪的外面。 9．無心磨刀板的刃部要磨鈍，以防割破手。 10．不得將超過規(guī)格的大料加入。 11．更換砂輪應(yīng)遵守磨工一般安全規(guī)程。數(shù)控磨床工作時(shí)，禁止操作者離開磨床或托人代管。如因停電或其他原因必須離開時(shí)，應(yīng)將砂輪離開工件后停車。</p><div style="width:100%;text-align: center;"><img

style="text-indent:25px">在磨床的加工制造中,外圓磨床的下工作臺(tái)、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(shí),加工后零件的幾何精度,必然會(huì)引起變化,掌握零件加工的臨床精度與其在實(shí)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。車間里加工主軸、絲桿、鏜桿完工后,均用鋼繩、鐵絲扎后吊在鐵架上,這是自由狀態(tài)安裝,而撓性零件的自由狀態(tài)是在A和B點(diǎn)支承的2/9L安裝。2/9L安裝時(shí)的自重變形量與二端支承和中間支承安裝的變形量相比都不足十幾分之一,說明2/9L安裝在生產(chǎn)中可當(dāng)作自由狀態(tài)安裝。磨床可以根據(jù)不同的用途和工藝方法進(jìn)行不同類別的分類。廣州工具磨床生產(chǎn)廠家</p><p style="text-indent:25px">磨床也可以使用油石、砂帶等其他磨具和游離磨料進(jìn)行加工。廣州工具磨床生產(chǎn)廠家</p><p style="text-indent:25px">刨削加工,以往采用**刨夾具而依靠操作者調(diào)節(jié)墊鐵壓板來達(dá)到加工要求,不但調(diào)節(jié)費(fèi)時(shí),而且加工質(zhì)量不穩(wěn)定,常因刨削質(zhì)量不佳,將零件送回退刨。為此設(shè)計(jì)制造了適合于加工下工作臺(tái)的**刨夾具,這樣能穩(wěn)定加工質(zhì)量,提高生產(chǎn)效率。刨夾具是由5個(gè)**部分組成,直接安裝在龍門刨床的工作臺(tái)面上,相當(dāng)于5套墊鐵。位于距離零件端面2/9L位置的二套墊鐵作主要定位支承一套墊鐵有2個(gè)固定支承點(diǎn),另一套墊鐵有相當(dāng)于1個(gè)固定支承點(diǎn)的一對(duì)浮動(dòng)支承點(diǎn),因而符合三點(diǎn)定位的原則。二端和中間墊鐵作輔助支承,其數(shù)量可按零件的長(zhǎng)短而增減,適當(dāng)選擇輔助支承墊鐵的數(shù)量和間隔可滿足不同長(zhǎng)度零件的加工要求。二端輔助墊鐵帶有壓板座,對(duì)工作進(jìn)行壓緊。這種壓緊方式的優(yōu)越性在于壓板的位置浮動(dòng),零件被夾緊時(shí)不產(chǎn)生變形,因而適合于精加工和零件夾緊點(diǎn)比較薄的場(chǎng)合。廣州工具磨床生產(chǎn)廠家</p></p><br
