    當(dāng)機械加工過程為深孔材料加工時,因在切削加工中主軸高速轉(zhuǎn)動,會產(chǎn)生大量的熱量,而傳統(tǒng)的冷卻方法為將切削液澆注到工件表面,切削液只能帶走工件表面熱量,無法為深孔中的工件和刀具降溫。尤其是鉆孔時,為保證可靠的冷卻潤滑、提高刀具壽命,通常會采用主軸中心出水的方式進行實現(xiàn)刀具降溫冷卻。
    主軸中心出水特點:
    1.降低刀具磨耗,節(jié)省刀具成本。
    2.改善鐵屑纏繞,有利于自動化導(dǎo)入。
    3.提升切削尺寸穩(wěn)定度,大幅增加工件良率。
    4.冷卻效果加倍,刀具壽命及加工質(zhì)量提升。
    5.濾筒精細過濾,優(yōu)化切削水質(zhì),保護刀具并防止管路阻塞。
    6.有效提升鉆孔深度及切削速度。
