    聊聊什么是硬轨立式加工中心

    对于硬(ying)轨(gui)(gui)(gui)(gui)(gui),J9九游会AG 聊得比(bi)较少,特(te)别是(shi)(shi)硬(ying)轨(gui)(gui)(gui)(gui)(gui)立(li)式(shi)加(jia)(jia)工(gong)(gong)中(zhong)(zhong)心。它不好(hao)用(yong)吗?其(qi)实不然。那(nei)么(me),硬(ying)轨(gui)(gui)(gui)(gui)(gui)立(li)式(shi)加(jia)(jia)工(gong)(gong)中(zhong)(zhong)心的特(te)点又是(shi)(shi)什么(me)?带着这样的疑问,今天小编(bian)就(jiu)为(wei)(wei)大家总结一下硬(ying)轨(gui)(gui)(gui)(gui)(gui)立(li)式(shi)加(jia)(jia)工(gong)(gong)中(zhong)(zhong)心的特(te)点吧。硬(ying)轨(gui)(gui)(gui)(gui)(gui)就(jiu)是(shi)(shi)指在机床(chuang)(chuang)的床(chuang)(chuang)身、立(li)柱等固定部件上直(zhi)接(jie)加(jia)(jia)工(gong)(gong)导轨(gui)(gui)(gui)(gui)(gui)使(shi)之成为(wei)(wei)一体,通过滑座(zuo)和工(gong)(gong)作台或其(qi)他移动部件连(lian)接(jie)。硬(ying)轨(gui)(gui)(gui)(gui)(gui)的刚性比(bi)较好(hao),能够承载(zai)的重(zhong)量(liang)比(bi)较大,对于重(zhong)切削方面的能力也很(hen)强。通过直(zhi)传使(shi)三轴(zhou)联动,轴(zhou)向推力大,采用(yong)宽广的底座(zuo),四(si)轨(gui)(gui)(gui)(gui)(gui)支承结构(gou)。因(yin)此应立(li)式(shi)加(jia)(jia)工(gong)(gong)中(zhong)(zhong)心适合用(yong)于大中(zhong)(zhong)型工(gong)(gong)件加(jia)(jia)工(gong)(gong),特(te)别是(shi)(shi)模具(ju)加(jia)(jia)工(gong)(gong)。硬(ying)轨(gui)(gui)(gui)(gui)(gui)立(li)式(shi)加(jia)(jia)工(gong)(gong)中(zhong)(zhong)...

    艾格玛加工中心是硬轨还是线轨的好?

    艾格(ge)(ge)玛(ma)加(jia)工中(zhong)心是硬(ying)轨(gui)(gui)还(hai)是线(xian)(xian)轨(gui)(gui)的好(hao)(hao)?其实艾格(ge)(ge)玛(ma)硬(ying)轨(gui)(gui)加(jia)工中(zhong)心和艾格(ge)(ge)玛(ma)线(xian)(xian)轨(gui)(gui)加(jia)工中(zhong)心没什么好(hao)(hao)不好(hao)(hao)之(zhi)说,只能(neng)说适(shi)合(he)不适(shi)合(he),因为他(ta)们的侧重(zhong)点不同。J9九游会AG 来看一(yi)(yi)下(xia)他(ta)们各自(zi)的优缺点。1.艾格(ge)(ge)玛(ma)硬(ying)轨(gui)(gui)加(jia)工中(zhong)心的优缺点及(ji)应用艾格(ge)(ge)玛(ma)硬(ying)轨(gui)(gui)加(jia)工中(zhong)心滑(hua)动(dong)接(jie)触(chu)面较大,刚性好(hao)(hao)、抗震(zhen)能(neng)力(li)强、承重(zhong)能(neng)力(li)强,适(shi)合(he)重(zhong)负(fu)荷切削。艾格(ge)(ge)玛(ma)硬(ying)轨(gui)(gui)加(jia)工中(zhong)心属于干摩(mo)擦(ca),由于接(jie)触(chu)面大,使得磨擦(ca)阻力(li)也(ye)较大,移动(dong)速(su)度不能(neng)太快。同时易产生爬行现象,移动(dong)表面存在间隙(xi)会导致加(jia)工误差。机床轨(gui)(gui)道的保养是重(zhong)中(zhong)之(zhi)重(zhong),一(yi)(yi)旦(dan)轨(gui)(gui)道润滑(hua)不充分(fen),就(jiu)会引起轨(gui)(gui)道烧死或...

    如何提高加工中心的加工精度?

    加(jia)工(gong)(gong)(gong)精(jing)度是指零件(jian)经机(ji)械(xie)加(jia)工(gong)(gong)(gong)后,其(qi)几何参(can)数(尺寸,形状,表面相互(hu)位置(zhi))的(de)(de)实(shi)际值与理(li)论值的(de)(de)符(fu)合程度。符(fu)合程度越高,加(jia)工(gong)(gong)(gong)精(jing)度越高。实(shi)际值与理(li)想值之(zhi)差(cha),称为(wei)加(jia)工(gong)(gong)(gong)误(wu)差(cha)。加(jia)工(gong)(gong)(gong)误(wu)差(cha)分(fen)为(wei)两(liang)大类:系统(tong)误(wu)差(cha)和随即误(wu)差(cha)。为(wei)提(ti)高加(jia)工(gong)(gong)(gong)中心的(de)(de)加(jia)工(gong)(gong)(gong)精(jing)度,生产厂家在提(ti)高数控系统(tong)分(fen)辨率(lv),提(ti)高位置(zhi)检测精(jing)度及在位置(zhi)伺(si)服系统(tong)中采用前(qian)馈(kui)控制与非线性控制等方法的(de)(de)同(tong)时,还(hai)开发、应(ying)用了多种补(bu)偿(chang)功(gong)能,对伺(si)服系统(tong)进行补(bu)偿(chang)。如齿轮间隙补(bu)偿(chang)、丝杠螺距(ju)误(wu)差(cha)补(bu)偿(chang)、空(kong)间误(wu)差(cha)补(bu)偿(chang)、刀县补(bu)偿(chang)等技术(shu)、热补(bu)偿(chang)技术(shu)等,以保证产品质(zhi)量。影(ying)响加(jia)工(gong)(gong)(gong)精(jing)度...
