【正文】 urther research. The procedure to design for the main shaft, launched a rigorous research and design.Lathe spindle is not only a single axis shaft, hollow shaft, the steps of the length to diameter ratio is less than 12 rigid shaft. Main processing surface is the surface of internal and external rotation, secondary surface with keyway, thread, and end face bined with holes, etc. Its mechanical processing mainly is turning and grinding, followed by milling and drilling. When turning, apply a clamp one or two top form. Avoid the shaft radial circular runout, which guarantees the stability of the processing of the workpiece, also make the workpiece dimensional accuracy.Grinding, use special hole grinding fixture, make consistent with the center line of the clamp workpiece axis, ensure the grinding hole of the inner hole machining accuracy.Turning and grinding using special fixture, cutting tools, measuring tool, not only ensure the dimensional accuracy, but also to reach a shaft assembly with other parts of tolerance and fit precision.To guarantee the cutting performance of the spindle, the finished product has enough hardness, wear resistance, shock resistance, and between different processing stages arranged heat treatment.Lathe spindle is one of the typical parts, processing is difficult, the craft route is longer, involves many basic process of shaft parts processing problem.Keywords: Process planning, Jig, The cutting tool, Measuring tool, Abrasive resistance序 言隨著科學(xué)技術(shù)的發(fā)展，各種新材料、新工藝和新技術(shù)不斷涌現(xiàn)，機(jī)械制造工藝正向著高質(zhì)量、高生產(chǎn)率和低成本方向發(fā)展。為了保證主軸的切削性能，成品具有耐磨性、抗震性及足夠的硬度，在不同的加工階段之間安排熱處理。磨削時，采用專用磨孔夾具，使工件軸線與夾具中心線保持一致，保證了磨孔時內(nèi)孔加工的精度。在車削時，應(yīng)用一夾一頂或兩頂尖的形式。它的機(jī)械加工主要是車削和磨削，其次是銑削和鉆削。車床主軸既是單一軸線的階梯軸、空心軸，又是長徑比小于12的剛性軸。 機(jī)械制造工藝學(xué)課程設(shè)計裝訂線題 目：階梯軸零件的加工工藝規(guī)程學(xué) 號： 姓 名： 教 學(xué) 院： 機(jī)械工程學(xué)院專業(yè)班級： 13級本（1）班指導(dǎo)教師： 完成時間： 2016年07月18日教務(wù)處制目錄摘要 4Abstract 5零件的工藝分析 7 軸的作用 7 軸的工藝分析 7 軸的零件圖 8確定毛坯 9 選擇毛坯 9 確定毛坯的尺寸公差 9．公差等級： 9： 9： 9．零件表面粗糙度： 9定位基準(zhǔn)的選擇 9 粗基準(zhǔn)的選擇 9 精基準(zhǔn)的選擇 10制定 工藝路線 10（公差等級由《互換性與測量技術(shù)基礎(chǔ)》附表5
