class="khcont5">絎磨與內(nèi)圓磨不同之處絎磨與內(nèi)圓磨不同,加工是用一珩磨頭伸進(jìn)孔內(nèi),然后由機(jī)器帶動(dòng)旋轉(zhuǎn),往復(fù),并漲出磨條進(jìn)行切削加工.機(jī)器是專用的珩磨機(jī).有立式和臥式之分.立式較適于大批量的較短件連續(xù)生產(chǎn),如氣缸套類(lèi).臥式的較適合較長(zhǎng)件的生產(chǎn).如果是加工鑄鐵類(lèi)的,生產(chǎn)效率轉(zhuǎn)內(nèi)圓磨的方式高幾倍.但鋼件珩磨效率比鑄鐵等要差點(diǎn),不過(guò)比起內(nèi)圓磨的方式還是要快很多.精度方面不是什么問(wèn)題,比起內(nèi)圓磨有過(guò)之而無(wú)不及.絎磨出來(lái)的管材主要應(yīng)用于液壓油缸、氣缸等叉車(chē)油缸管上絎磨管的應(yīng)用知識(shí)絎磨管是一種通過(guò)冷拔或熱軋?zhí)幚砗蟮囊环N高精密的鋼管材料。由于精密鋼管內(nèi)外壁無(wú)氧化層、承受高壓無(wú)泄漏、高精度、高光潔度、冷彎不變形、擴(kuò)口、壓扁無(wú)裂縫等優(yōu)點(diǎn)，所以主要用來(lái)生產(chǎn)氣動(dòng)或液壓元件的產(chǎn)品，如氣缸或油缸，可以是無(wú)縫管。絎磨管的化學(xué)成分有碳C、硅Si、錳Mn、硫S、磷P、鉻Cr。<br

4、加工后有殘余應(yīng)力層,提高疲勞強(qiáng)度提高30%。<br /> 5、提高配合質(zhì)量，減少磨損，延長(zhǎng)零件使用壽命，但零件的加工費(fèi)用反而降低。 <br /> 珩磨管和無(wú)縫鋼管的區(qū)別 <br /> 1、無(wú)縫鋼管主要特點(diǎn)是無(wú)焊接縫，可承受較大的壓力。產(chǎn)品可以是很粗糙的鑄態(tài)或冷撥件。<br /> 2、絎磨管是近幾年出現(xiàn)的產(chǎn)品，主要是內(nèi)孔、外壁尺寸有嚴(yán)格的公差及粗糙度。<br /> 20號(hào)優(yōu)質(zhì)絎磨管是一種根據(jù)冷扎或冷拉解決后的精密加工的無(wú)縫鋼管;全名：冷扎或冷拉20號(hào)優(yōu)質(zhì)絎磨管。因?yàn)榫茕摴軆?nèi)外壁無(wú)空氣氧化層、承擔(dān)髙壓無(wú)滲漏、高精密、高光滑度、冷拔不形變、擴(kuò)口、擠扁無(wú)縫隙等優(yōu)勢(shì)，因此關(guān)鍵用于制造氣動(dòng)式或液壓件的商品，如汽缸或液壓缸，全是用無(wú)縫鋼管。精密鋼管的成分有碳C、硅Si、錳Mn、硫S、磷P、鉻Cr。<br /> 絎磨管采用加工工藝油缸管采用滾壓加工，由于表面層留有表面殘余壓應(yīng)力，有助于表面微小裂紋的封閉，阻礙侵蝕作用的擴(kuò)展。從而提高表面抗腐蝕能力，并能延緩疲勞裂紋的產(chǎn)生或擴(kuò)大，因而提高絎磨管疲勞強(qiáng)度。通過(guò)滾壓成型，滾壓表面形成一層冷作硬化層，減少了磨削副接觸表面的彈性和塑性變形，從而提高了絎磨管內(nèi)壁的耐磨性，同時(shí)避免了因磨削引起的燒傷。滾壓后，表面粗糙度值的減小，可提高配合性質(zhì)。</div><p><img
