3、刀具與夾具 切削加工及刀具是裝備制造業(yè)的基礎(chǔ)工藝，是制造業(yè)重要工業(yè)部門如汽車工業(yè)、家電制造業(yè)、航空航天、能源工業(yè)、模具工業(yè)等發(fā)展的關(guān)鍵技術(shù)。 現(xiàn)代切削技術(shù)經(jīng)過近百年的快速發(fā)展，到 20 世紀末，隨著數(shù)控機床、數(shù)控系統(tǒng)、刀具材料、涂層技術(shù)等制造技術(shù)的全面進步，達到了新的水平，使切削加工進入了高速切削的新階段，其主要技術(shù)特征表現(xiàn)為切削速度有 5 10 倍的提高。高速切削技術(shù)的出現(xiàn)，對制造領(lǐng)域又提出了高要求。一是機床本身剛性、精度高，二是裝夾系統(tǒng)剛性、精度高。三是刀具的材料性能和加工精度要高。四是冷卻效果要好。 。

4、專用鉆床 夾具 是針對特定零件孔加工時使用的夾具。此類鉆床夾具能較易保證孔之間的位置精度，提高生產(chǎn)效率。應用此鉆模能 極大地提高勞動生產(chǎn)率、降低操作工人的勞動強度 ,減小鉆頭的損耗 ,長刀具的使用壽命 。 在夾具設計工作中，一般具有下列特點： 1、夾具的設計周期較短，一般不進行強度和剛度計算； 2、專用夾具的設計，對產(chǎn)品零件有較強的針對性； 3、確保產(chǎn)品加工質(zhì)量，提高勞動生產(chǎn)率是夾具設計工作的首要任務； 4、夾緊裝置的設計對整個夾具的結(jié)構(gòu)具有決定性的影響。夾具設計的原則是經(jīng)濟和實用，夾具設計的基本要求有以下三方。
