style="text-indent:25px">磨床是金屬切削機床的一種,各種類別型號的磨床都有大件零件如床身、工作臺、墊板、砂輪架體殼、拖板等,特大型磨床有30只左右件號的大件零大件。鑄鐵件由于零件的筋、壁的厚薄不均勻,鐵水澆入砂箱后零件的各部分冷卻速度不一樣,筋、壁厚處冷卻得慢,筋、壁薄處冷卻得快,引起收縮不均勻而產(chǎn)生鑄造應力。零件全部冷卻后,內(nèi)應力處于暫時平衡,當切削加工從毛坯表面切去一層金屬后引起內(nèi)應力的重新分布產(chǎn)生加工應力(切削應力)使零件變形。內(nèi)應力是造成零件精度不穩(wěn)定的主要因素。工藝上必須設法把內(nèi)應力消除到zui小的程度,必須采取時效的方法。時效分人工時效和天然時效。廣州磨床加工廠隨著高精度、高硬度機械零件數(shù)量的增加，磨床的性能、品種和產(chǎn)量都在不斷的提高和增長。</p><div

style="text-indent:25px">磨床可進行荒加工、粗加工、精加工和超精加工，可以進行各種高硬、超硬材料的加工,還可以刃磨刀具和進行切斷等，工藝范圍十分普遍。隨著科學技術(shù)的發(fā)展,對機械零件的精度和表面質(zhì)量要求越來越高,各種高硬度材料的應用日益增多。精密鑄造和精密鍛造工藝的發(fā)展,使得有可能將毛坯直接磨成成品。高速磨削和強力磨削,進一步提高了磨削效率。因此,磨床的使用范圍日益擴大。它在金屬切削機床所占的比重不斷上升。目前在工業(yè)發(fā)達的國家中，磨床在機床總數(shù)中的比例已達30%-40%。</p><p> 在外圓磨床上加工制造同軸桿，其定位方式有兩種，一種是對于直徑較大的同軸桿，在車工工序粗加工時，在同軸桿兩端加工出中心孔，進行熱處理后，外圓磨工序?qū)χ行目走M行研磨修整，以后就作為外圓磨削的定位基準；另一種是對于小直徑的同軸桿，在車工工序粗加工時，在同軸桿較粗的一端加工出中心孔，另一端車尖加工，進行熱處理后，外圓磨工序?qū)σ欢酥行目走M行研磨修整，對車尖的另一端進行磨削加工，通過調(diào)整磨床的角度，加工出小直徑端60°外錐前列，來作為磨削外圓時的定位基準。 </p> <p> <br /> 數(shù)控內(nèi)圓磨床，其是數(shù)控磨床中的一種。</p><div style="width:100%;text-align: center;"><img style="max-width: 640px; max-height: 320px;" alt="沈陽自動平面磨床,磨"

style="text-indent:25px">磨床床身和工作臺的導軌筋主要采用直形筋、人形筋、米形筋。導軌主要受壓,米形筋的變形比直形筋、人形筋小,直形筋、人形筋鑄造工藝較米形筋簡單、省料,米形筋剛性好,但鑄造工藝復雜。合理布置及選擇筋的形狀,能提高零件的剛性。床身是磨床的基礎,也是關(guān)鍵的零件之一,它與各部件都有聯(lián)系。床身的導軌不僅是機床各項幾何精度的測定基準,而且它的精度直接影響磨床的加工精度,所以對床身和床身導軌設計加工制造的基本要求,要保證具有一定的精度、剛性、耐磨性、zui小的熱變形以及合理的結(jié)構(gòu)工藝性。磨床要有專人負責保養(yǎng)和使用，定期檢修，這樣才能確保機床是一直處于良好的狀態(tài)。廣州磨床加工廠</p><p style="text-indent:25px">磨床可以分為普通、精加工、專門化磨床。沈陽自動平面磨床</p><p> 磨削準備： </p> <p> （1）機床及輔具的準備：由于該零件位置及尺寸精度要求高，因此要求磨床主軸旋轉(zhuǎn)精度在0.001 2mm以內(nèi)，所用精密分度頭具有調(diào)心功能及精密回轉(zhuǎn)精度。另外，為了保證磨削過程中，工裝中心軸線與砂輪旋轉(zhuǎn)軸心平行，應準備磁力表架、百分表，為了保證所加工工裝的圓柱度要求，方便加工過程中對工裝圓柱度的調(diào)整，同時應準備0.02-1mm塞尺一副。 </p> <p> （2）工件準備：針對零件的使用性能及加工要求，零件材質(zhì)選用高速鋼、碳素工具鋼T10A和合金工具鋼CrWMn等。先進行車削加工，頂部 φ4mm部分完成并加工出中心孔，外圓 φ0.7－0－0.005 mm及 φ0.372－0－0.006 m m部分留0.5～0.6mm磨削加工余量，之后進行淬火處理（要防止熱處理變形）；淬火后，在外圓磨床上自定心卡盤夾持 φ 4mm部分，在φ 0.372mm部分磨出外錐前列，然后夾持將φ4mm部分光亮無錐度，φ0.7mm、φ0.372mm部分留精加工余量0.3mm。 </p> <p> （3）砂輪準備：為達到工件尺寸、形位精度及表面粗糙度要求，砂輪宜選用中軟、細粒度的規(guī)格。沈陽自動平面磨床</p></p><br /><p>文章來源地址:
