數(shù)控加工中所使用的切削刀具包括刀具，也包括用于磨料和磨料的“刀具”以及切削刀片刀具和刀架附件。因此在進(jìn)行加工的時(shí)候要選擇合適的刀具才能保障加工的順利進(jìn)行，那么選擇刀具的時(shí)候應(yīng)考慮哪些因素呢?數(shù)控刀具使用時(shí)應(yīng)該如何進(jìn)行選擇?一、生產(chǎn)性質(zhì)這里指的是生產(chǎn)批量的零件的尺寸及加工成本對于刀具選擇的影響。例如在大批量生產(chǎn)中使用特殊的刀具就比較合適，但在單個(gè)或小批量生產(chǎn)中使用標(biāo)準(zhǔn)刀具才更有利。二、機(jī)器類型在工藝中選擇刀具類型(鉆頭、車削或銑刀)會(huì)影響充電式數(shù)控機(jī)床的完整性能確保系統(tǒng)的工件和刀具系統(tǒng)的剛性和允許高生產(chǎn)力的刀具如切削車床進(jìn)給刀具。三、數(shù)控加工程序不同的數(shù)控加工解決方案可用于不同類型的刀具。例如鉆孔和鉸孔也可以使用鉆孔和鉆孔。四、工件的尺寸和形狀工件的尺寸和形狀也影響刀具的類型和規(guī)格，如表面需要進(jìn)行特殊處理的時(shí)候使用特殊的金屬切削刀具及比較合適。青島精密數(shù)控刀具供應(yīng)商隨著國內(nèi)用戶越來越多使用高級(jí)數(shù)控設(shè)備，超硬刀具將獲得更好的發(fā)展。</p><div

由于過多的熱量和壓力所導(dǎo)致的切削刃扭曲。刀片在前刀面以及刀尖半徑周圍出現(xiàn)下卷的現(xiàn)象。刀片也在前刀面后卷處隆起，第二個(gè)隆起直接位于刀具后刀面的卷曲處。如果任其發(fā)展，熱變形會(huì)導(dǎo)致切削刃斷裂。熱變形是由切削刃高溫和高壓共同作用的結(jié)果。過高的速度加上堅(jiān)硬或堅(jiān)韌的工件材料會(huì)產(chǎn)生足夠的熱量，使切削刃的熱硬度發(fā)生改變。此外，過高的進(jìn)給速度和切削深度共同作用產(chǎn)生出足夠的力使軟化的切削刃變形。由于鑄造、鍛造或熱處理，有些工件可能有外部銹層，這主要是由氧化物組成并且通常很堅(jiān)硬。加工過程中，該堅(jiān)硬的外層會(huì)導(dǎo)致加速磨損，并在切深處形成缺口。 </p><p> 現(xiàn)代制造技術(shù)的發(fā)展及數(shù)控加工設(shè)備的使用，極大地推動(dòng)了切削技術(shù)的進(jìn)步。隨著生產(chǎn)加工過程數(shù)控化和自動(dòng)化的需要，超耐熱合金、鈦合金及含有碳纖維的復(fù)合材料等的出現(xiàn)，對金屬切削刀具的質(zhì)量要求更加苛刻，高可靠度、高精度、長壽命、快速轉(zhuǎn)位更換、斷屑良好等，刀具的熱硬性和刀具磨損問題成為切削加工的關(guān)鍵。常見的刀具磨損形態(tài)在切削加工中，通常出現(xiàn)的刀具磨損包括如下三種形態(tài)：第一種是由于機(jī)械作用而出現(xiàn)的磨損，如崩刃或磨粒磨損等;第二種由于切削熱作用而出現(xiàn)的磨損，如粘結(jié)、擴(kuò)散等;第三種是由于化學(xué)因素導(dǎo)致的切削刃軟化、溶融而產(chǎn)生的破斷、熱疲勞、熱龜裂等。(1)機(jī)械磨損產(chǎn)生的原因切削難加工材料時(shí)，在很短時(shí)間內(nèi)出現(xiàn)刀具磨損，這是由于被加工材料中存在較多促使刀具磨損的因素。多數(shù)難加工材料均具有熱傳導(dǎo)率較低的特點(diǎn)，這種影響的結(jié)果會(huì)使刀具材料中的粘結(jié)劑在高溫下粘結(jié)強(qiáng)度下降，從而加速了刀具磨損。例如在大批量生產(chǎn)中使用特殊的刀具就比較合適，但在單個(gè)或小批量生產(chǎn)中使用標(biāo)準(zhǔn)刀具才更有利。</p><div
