style="text-indent:25px">車刀材料應(yīng)具備的性能刀具材料是指刀具切削部分的材料。金屬切削時(shí)，刀具切削部分直接和工件及切屑相接觸，承受著很大的切削壓力和沖擊，并受到工件及切屑的劇烈摩擦，產(chǎn)生很高的切削溫度。因此，刀具材料應(yīng)具備一定的性能。1.足夠的硬度一般來說，刀具材料的硬度必須高于被切工件材料的硬度，常溫硬度要求60HRC以上，除此之外，還必須具備較高的高溫硬度（熱硬性）和顯微硬度（金相組織硬度）2.高耐磨性和耐熱性刀具材料的耐磨性是指抵抗磨損的能力。一般說，刀具材料硬度越高，耐磨性也越好，但材料的耐磨性不單純?nèi)Q于材料的硬度，也并非材料越硬耐磨性越高。因?yàn)橛捕冗^高，內(nèi)應(yīng)力增加，可能會(huì)加快表層的破壞，使耐磨性降低。硬質(zhì)合金焊接車刀所謂焊接式車刀。</p><div
