機(jī)床立柱鑄件

型號(hào)說明：
機(jī)床立柱鑄件是機(jī)床重要的結(jié)構(gòu)件，起著機(jī)床上下運(yùn)動(dòng)及支撐作用。機(jī)床立柱鑄件材質(zhì)常見的為HT250,這種材質(zhì)強(qiáng)度、耐磨性、耐熱性均較好，減振性良好，鑄造性能較優(yōu)，需進(jìn)行人工時(shí)

產(chǎn)品詳情

機(jī)床立柱鑄件是機(jī)床重要的結(jié)構(gòu)件，起著機(jī)床上下運(yùn)動(dòng)及支撐作用。

機(jī)床立柱鑄件材質(zhì)常見的為HT250,這種材質(zhì)強(qiáng)度、耐磨性、耐熱性均較好，減振性良好，鑄造性能較優(yōu)，需進(jìn)行人工時(shí)效處理。除此之外經(jīng)常用到的還有HT200 HT300 或球墨鑄鐵，根據(jù)不同工作要求而定。

機(jī)床立柱加工要求主要體現(xiàn)在其導(dǎo)軌面的精度及硬度，檢驗(yàn)標(biāo)準(zhǔn)與機(jī)床床身導(dǎo)軌面相當(dāng)，一般不超過3道，導(dǎo)軌硬度根據(jù)材質(zhì)不同，淬火完成后分別為HT250----HRC46—50 HT300----HRC48—52 ，淬火深度2.5-3mm。

機(jī)床立柱的作用

加工中心立柱主要是對(duì)主軸箱起到支撐作用，滿足主軸的Z向運(yùn)動(dòng)。普遍采用的是雙立柱框架結(jié)構(gòu)設(shè)計(jì)形式，對(duì)于大中型的移動(dòng)立柱固定于滑座上。因?yàn)榱⒅沁B接床身與主軸、刀庫的重要部件，所以它的設(shè)計(jì)必須得到重視。對(duì)于主軸來講，正確的安裝立柱對(duì)于加工中心加工出合格的零件有著不能忽視的作用，而立柱的安裝主要反映在其與工作臺(tái)的垂直度上。
