線軌數控車床一般指的是滾動導軌。常見結構有滾珠導軌和滾柱導軌兩種，其區別是滾珠導軌為點接觸型，滾柱導軌為線接觸型，其原理都是一致的，同樣都是在導軌上滾動來帶動滑。線軌有滾珠和滾柱兩種線軌運動速度快精度高穩定性好。線軌經過預緊處理可達到軌道間零間隙以及各方向上的滿承載能力. 線軌數控車床外罩部分(fen)包括外罩、內(nei)蓋(gai)(gai)板(ban)(ban)(ban)(ban)(ban)(ban)、活(huo)動門(men)、觀(guan)察窗、擋(dang)(dang)板(ban)(ban)(ban)(ban)(ban)(ban)、側蓋(gai)(gai)板(ban)(ban)(ban)(ban)(ban)(ban)組、上蓋(gai)(gai)板(ban)(ban)(ban)(ban)(ban)(ban)組、后(hou)(hou)蓋(gai)(gai)板(ban)(ban)(ban)(ban)(ban)(ban)、操(cao)(cao)作(zuo)面(mian)板(ban)(ban)(ban)(ban)(ban)(ban)。外罩固定(ding)于(yu)(yu)(yu)(yu)(yu)底座上，內(nei)蓋(gai)(gai)板(ban)(ban)(ban)(ban)(ban)(ban)及(ji)活(huo)動門(men)活(huo)動連(lian)接于(yu)(yu)(yu)(yu)(yu)外罩，內(nei)蓋(gai)(gai)板(ban)(ban)(ban)(ban)(ban)(ban)及(ji)活(huo)動門(men)夾住觀(guan)察窗并能(neng)帶動其水平移動，內(nei)蓋(gai)(gai)板(ban)(ban)(ban)(ban)(ban)(ban)及(ji)活(huo)動門(men)上開(kai)設(she)(she)有與(yu)觀(guan)察窗相對(dui)應的窗口，擋(dang)(dang)板(ban)(ban)(ban)(ban)(ban)(ban)設(she)(she)置于(yu)(yu)(yu)(yu)(yu)底座以(yi)擋(dang)(dang)住工作(zuo)時產生(sheng)的水和鐵(tie)屑，側蓋(gai)(gai)板(ban)(ban)(ban)(ban)(ban)(ban)組、上蓋(gai)(gai)板(ban)(ban)(ban)(ban)(ban)(ban)組分(fen)別(bie)包括多個可拆(chai)卸的蓋(gai)(gai)板(ban)(ban)(ban)(ban)(ban)(ban)，側蓋(gai)(gai)板(ban)(ban)(ban)(ban)(ban)(ban)組設(she)(she)置于(yu)(yu)(yu)(yu)(yu)外罩靠近(jin)擋(dang)(dang)板(ban)(ban)(ban)(ban)(ban)(ban)一側的側面(mian)，上蓋(gai)(gai)板(ban)(ban)(ban)(ban)(ban)(ban)組設(she)(she)置于(yu)(yu)(yu)(yu)(yu)外罩的頂部，后(hou)(hou)蓋(gai)(gai)板(ban)(ban)(ban)(ban)(ban)(ban)、操(cao)(cao)作(zuo)面(mian)板(ban)(ban)(ban)(ban)(ban)(ban)均為可拆(chai)卸式，后(hou)(hou)蓋(gai)(gai)板(ban)(ban)(ban)(ban)(ban)(ban)設(she)(she)置于(yu)(yu)(yu)(yu)(yu)外罩的后(hou)(hou)端，操(cao)(cao)作(zuo)面(mian)板(ban)(ban)(ban)(ban)(ban)(ban)連(lian)接并覆蓋(gai)(gai)操(cao)(cao)作(zuo)部分(fen)，操(cao)(cao)作(zuo)部分(fen)固定(ding)于(yu)(yu)(yu)(yu)(yu)外罩上。
線(xian)軌數控車床(chuang)優點：
1、線性導(dao)軌(gui)由滾(gun)動零件支(zhi)撐，其滾(gun)動滑行性能要強(qiang)于硬(ying)軌(gui)磨擦(ca)滑行性能，無爬(pa)行現(xian)像；
2、同樣因(yin)為磨擦系數小(xiao)(xiao)，所以磨損(sun)較小(xiao)(xiao)；
3、一(yi)般線性導軌都選用較(jiao)好的材料和較(jiao)精(jing)(jing)密(mi)的設備制造，所(suo)以其(qi)精(jing)(jing)度也較(jiao)高；
4、由于其磨擦系(xi)數小，所(suo)以移(yi)動速度較(jiao)快；
5、后期維修方(fang)便(bian),在導軌磨損(sun)后，線軌更換方(fang)便(bian)，硬軌較麻煩(fan)，因為(wei)要調間隙。
缺點：由于其接觸面較小，所以其剛性要低于硬軌。
