6．工件未從砂輪磨出時，不準取出。手接工件時，要迅速把工件握住，停止其轉動。 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，要戴手套。拿螺旋輪的端面內孔，不準拿螺旋輪的外面。 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。

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精度在0.001 2mm以內，所用精密分度頭具有調心功能及精密回轉精度。另外，為了保證磨削過程中，工裝中心軸線與砂輪旋轉軸心平行，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。數(shù)控磨床工件的裝卡必須符合規(guī)定。對因故中斷加工的工件，必須確認狀態(tài)良好后，方準開車工作。</p><div

style="text-indent:25px">鑄件的排列和支承應有利于時效爐內氣的流通和鑄件的均勻受熱。一般按大的、重的在下面,小的輕的在上面的原則搭配放置,而臺面類鑄件須單獨放置。為避免在時效過程中,鑄件發(fā)生變形,一般支距原則上小于600mm。鑄件與烘車火道平面的距離大于100mm,爐頂內壁與zui高鑄件的距離大于300mm,前后爐門內與鑄件的距離大于200mm,二測內壁與鑄件的距離大于200mm。高精度數(shù)控、有特殊要求的磨床零件,須經2-3次人工時效處理。并且希望工作臺比床身導軌硬度要低,烘一次硬度會降低HBI0。磨床的床身及臺面在進時效爐前和出時效爐后抽查硬度,時效后允許硬度降低HB10-15。成都精密外圓磨床廠家</p></p><br
