為提高精拉刀的使用壽命，保證其輪廓的正確性，設(shè)計(jì)時(shí)拉刀輪廓取輪槽輪廓的尺寸，這樣拉刀實(shí)體處于輪槽輪廓的尺寸。在全齒型精切削時(shí)，拉力突然增大，拉刀容易產(chǎn)生振動(dòng)，產(chǎn)生崩齒或拉刀折斷情形，不僅工件毀損，而且會(huì)造成拉刀的損失，為避免這種情況的發(fā)生，設(shè)計(jì)精拉刀時(shí)要計(jì)算出全齒型切削時(shí)的齒數(shù)，將這些齒的齒根、齒底開分屑槽，才能保證有效地?cái)嘈?。拉刀的修銳研磨拉刀在使用時(shí)會(huì)逐漸的磨損，當(dāng)拉刀磨損到一定情況時(shí)會(huì)影響后加工的度和整組拉刀的壽命，所以當(dāng)加工中出現(xiàn)異常情況，如表面質(zhì)量突然下降或拉刀振動(dòng)增大時(shí)必須將拉刀置在刀具磨床上重新磨銳，一般磨銳的拉刀僅限于粗拉刀齒的部位，研磨的位置也僅限于后斜角的那一面，研磨拉刀大多使用CBN砂輪或鉆石砂輪，一次研磨一個(gè)齒，并應(yīng)注意校正齒距，避免過多地研磨，刀刃磨過后，每把拉刀必須進(jìn)行探傷、消磁、才能再次使用。

不銹鋼制品以其精外表、優(yōu)良的抗腐蝕性、抗高溫氧化性及高低溫強(qiáng)度，而愈來愈廣泛地用于很多行業(yè)。由于這類產(chǎn)品外觀質(zhì)量要求較高，在產(chǎn)品的整個(gè)加工過程中，要保證高光亮度的產(chǎn)品表面不劃傷和擦傷難度確實(shí)很大，特別是由于不銹鋼薄板拉深特性所帶來的模具選材、熱處理、加工及工藝潤滑等問題直接影響到產(chǎn)品質(zhì)量、產(chǎn)量、成本及模具壽命。模具工作部分材料選擇，針對(duì)皺紋問題，經(jīng)過實(shí)踐證明：選用鑄鋁青銅、硬鋁青銅防粘效果較好;采用碳化鎢鋼結(jié)硬質(zhì)合金制造凹模比用Cr12Mov軟氮化制造凹模壽命提高數(shù)倍，且不粘模;如果采用代號(hào)354合金鑄鐵，只需在模具表面進(jìn)行火焰淬火，模具表面不會(huì)出現(xiàn)皺紋。
