不銹鋼坯(pi)料(liao)的(de)(de)端(duan)面加工(gong)(gong)(gong)(gong)設備主要完成(cheng)兩道工(gong)(gong)(gong)(gong)序，即平端(duan)面加工(gong)(gong)(gong)(gong)和加工(gong)(gong)(gong)(gong)潤滑(hua)劑錐形(xing)體(ti)。采用(yong)多軸加工(gong)(gong)(gong)(gong)機床加工(gong)(gong)(gong)(gong)坯(pi)料(liao)端(duan)面的(de)(de)一個例子(zi)是德(de)國的(de)(de)DSM12/1400=2/1型(xing)加工(gong)(gong)(gong)(gong)機床，在此機床上可同(tong)時完成(cheng)端(duan)面加工(gong)(gong)(gong)(gong)和潤滑(hua)劑錐體(ti)的(de)(de)加工(gong)(gong)(gong)(gong)。

  不銹鋼坯料逐個被送到機床的第一個工位，一方面加工端面，另一方面初步車出錐體；隨后坯料進入第二個工位，進行錐體的精加工。機床可以加工φ140~250mm,長度350~700mm的坯料。

  加工(gong)平端面的(de)表面粗糙(cao)度為(wei)5μm,平端面與(yu)坯(pi)料軸(zhou)(zhou)線垂(chui)直度的(de)偏差(cha)不大于(yu)0.2mm,錐體部(bu)軸(zhou)(zhou)線與(yu)坯(pi)料軸(zhou)(zhou)線的(de)偏差(cha)不超(chao)過0.25mm,在(zai)端面加工(gong)中，被車削(xue)的(de)金(jin)屬層深度為(wei)2mm.

  不銹(xiu)鋼(gang)坯料(liao)(liao)必須在(zai)前端（相當于穿孔筒內襯的(de)下端）加工(gong)成圓角，在(zai)尾端加工(gong)成喇(la)叭口。而用于穿孔的(de)碳素(su)鋼(gang)和低合金鋼(gang)坯料(liao)(liao)，只需在(zai)前端倒(dao)棱即可。機械加工(gong)后(hou)的(de)不銹(xiu)鋼(gang)坯料(liao)(liao)需要(yao)進行脫脂處理(li)。一般采(cai)用3%的(de)堿溶液，溫(wen)度(du)為(wei)60~80℃,噴洗壓(ya)力(li)500kPa.堿洗后(hou)再用熱水沖洗，然后(hou)熱風吹干，防止在(zai)加熱和擠壓(ya)過程中表面滲碳。
