style="text-indent:25px">砂輪是磨削的切削工具,它由許多細(xì)小而堅(jiān)硬的磨粒和結(jié)合劑粘而成的多孔物體。磨粒直接擔(dān)負(fù)著切削工作，必須鋒利并具有高的硬度，耐熱性和一定的韌性。常用的磨料有氧化鋁和碳化硅兩種。氧化鋁類磨料硬度高、韌性好,適合磨削鋼料。碳化硅類磨料硬度更高、更鋒利、導(dǎo)熱性好,但較脆,適合磨削鑄鐵和硬質(zhì)合金。同樣磨料的砂輪,由于其粗細(xì)不同,工件加工后的表面粗糙度和加工效率就不相同，磨粒粗大的用于粗磨,磨粒細(xì)小的適合精磨、磨料愈粗,粒度號(hào)愈小。結(jié)合劑起粘結(jié)磨料的作用。常用的是陶瓷結(jié)合劑，其次是樹(shù)脂結(jié)合劑，結(jié)合劑選料不同,影響砂輪的耐蝕性、強(qiáng)度、耐熱性和韌性等。天津數(shù)控平面磨床公司平面磨床企業(yè)要努力實(shí)現(xiàn)制造業(yè)服務(wù)化，重點(diǎn)在于要以客戶為中心，積極提供客戶需要的個(gè)性化服務(wù)。</p><div

2）開(kāi)始加工前或每次測(cè)量后繼續(xù)加工時(shí)，工件都要在砂輪開(kāi)始旋轉(zhuǎn)前旋轉(zhuǎn)。每一次加工完成后，工件都要在砂輪停止旋轉(zhuǎn)后停止旋轉(zhuǎn)。 </p> <p> 3）每次對(duì)工件進(jìn)行測(cè)量時(shí)，要等砂輪完全停止旋轉(zhuǎn)后方能從Y軸方向退刀。 </p> <p> 4）測(cè)量時(shí)要輕、穩(wěn)，減少量具的擺動(dòng)，以防折彎或折斷工件。測(cè)量時(shí)應(yīng)對(duì)工件前后兩端同時(shí)測(cè)量，以查看尺寸差a情況。 </p> <p> 5）墊塞尺的厚度依據(jù)細(xì)桿前后兩端的尺寸差計(jì)算，即x＝la/（2×12），其中12為磨削長(zhǎng)度（mm）。為確保定位穩(wěn)定，要同時(shí)墊兩組且不可墊入過(guò)長(zhǎng)，以墊入15mm左右為宜。 </p><p style="text-indent:25px">在砂輪架傳動(dòng)裝置設(shè)采用了多楔帶皮帶和多楔帶帶輪。多楔帶兼有V帶和平帶的優(yōu)點(diǎn)，外輪廓尺寸小，比V型帶傳動(dòng)平穩(wěn)。多楔帶以平帶為基體,內(nèi)表面有等距離縱向楔型的環(huán)形帶傳動(dòng),工作面為楔側(cè)面。為了減少外載荷對(duì)砂輪架影響，提高砂輪架主軸的承載力，在帶輪的安裝方面，采用了卸荷皮帶輪的方案,即多楔帶皮帶輪不是直接安裝在砂輪架主軸上，而是安裝在支架上,然后通過(guò)花鍵套來(lái)傳遞扭矩,帶動(dòng)砂輪架主軸旋轉(zhuǎn)。好處是砂輪架承受的軸向力大幅地減小了,砂輪架主要承受扭矩,達(dá)到減小砂輪架主軸變形、提高砂輪架主軸的承載能力和提高旋轉(zhuǎn)精度等目的。數(shù)控磨床是有數(shù)控平面磨床、數(shù)控?zé)o心磨床、數(shù)控內(nèi)外圓磨床、數(shù)控立式磨床、數(shù)控坐標(biāo)磨床等這些。</p><div
