2我需要选用什么规格的卧式加工中心?——主要规格的选定

(1)工作台尺寸(cun)

这(zhei)是(shi)卧式加工(gong)(gong)(gong)中(zhong)心的(de)主(zhu)参数,主(zhu)要取(qu)决于典(dian)型零(ling)件(jian)的(de)外(wai)廓(kuo)尺(chi)(chi)寸(cun)、装(zhuang)夹方式等。应(ying)选择比(bi)典(dian)型零(ling)件(jian)外(wai)廓(kuo)尺(chi)(chi)寸(cun)稍(shao)大(da)一些(xie)的(de)工(gong)(gong)(gong)作台(tai),以便留出安装(zhuang)夹具所需(xu)的(de)空(kong)间,保证零(ling)件(jian)在其上面能够顺利装(zhuang)夹,此外(wai)还应(ying)考虑(lv)工(gong)(gong)(gong)作台(tai)的(de)承载能力、T形槽(cao)数量和(he)尺(chi)(chi)寸(cun)等,小(xiao)尺(chi)(chi)寸(cun)的(de)比(bi)较通用,比(bi)如站内的(de)卧式加工(gong)(gong)(gong)中(zhong)心MH-630A、MH-800A、MH-500A、LH-630B等。

建议:目(mu)前市场上的卧式加(jia)工中心工作台尺(chi)寸多为(wei)1000以(yi)下的,能够满足大多数用(yong)户的需(xu)求。

(2)坐标轴(zhou)行(xing)程

最(zui)基本的(de)(de)坐标(biao)轴(zhou)(zhou)是X、Y、Z三(san)轴(zhou)(zhou),其(qi)行程和(he)工(gong)作台(tai)尺(chi)寸有相应(ying)的(de)(de)比(bi)例(li)关系,工(gong)作台(tai)面的(de)(de)大(da)小(xiao)基本上确定(ding)了加工(gong)空间的(de)(de)大(da)小(xiao)。如(ru)(ru)个别零件(jian)的(de)(de)尺(chi)寸大(da)于卧(wo)式(shi)加工(gong)中(zhong)心(xin)行程时(shi),则(ze)必须要(yao)(yao)求零件(jian)的(de)(de)加工(gong)区(qu)域处于机床的(de)(de)行程范围之内,此外还要(yao)(yao)考虑零件(jian)是否与(yu)机床交换刀具(ju)的(de)(de)空间干涉(she)、与(yu)机床防护罩(zhao)等(deng)附件(jian)发生干涉(she)等(deng)系列问(wen)题。而对需(xu)要(yao)(yao)多轴(zhou)(zhou)联(lian)动加工(gong)的(de)(de)卧(wo)式(shi)加工(gong)中(zhong)心(xin) (如(ru)(ru)增加回(hui)转坐标(biao)A、B、C或附加坐标(biao)U、V、W),如(ru)(ru)四轴(zhou)(zhou)、五轴(zhou)(zhou)联(lian)动卧(wo)式(shi)加工(gong)中(zhong)心(xin),这就需(xu)要(yao)(yao)特殊订货,同(tong)时(shi)必须对相应(ying)配套的(de)(de)编(bian)程软件(jian)、测量手段以及机床价格等(deng)有全面的(de)(de)考虑和(he)安排(pai)。

建议:采购用户需(xu)要根据加工工件规格(ge)选择(ze)不同坐标轴(zhou)行程(cheng)的卧式加工中(zhong)心,多(duo)轴(zhou)联动需(xu)要特(te)殊定制。

(3)主轴电动机功率与转矩

它反映了卧式(shi)(shi)加工(gong)(gong)(gong)中(zhong)(zhong)心(xin)的(de)(de)切削(xue)效率,也从一个侧面反映了卧式(shi)(shi)加工(gong)(gong)(gong)中(zhong)(zhong)心(xin)的(de)(de)切削(xue)刚(gang)性和机(ji)(ji)床整(zheng)体(ti)刚(gang)度。主(zhu)轴电(dian)动(dong)机(ji)(ji)功率在(zai)同类规格(ge)的(de)(de)卧式(shi)(shi)加工(gong)(gong)(gong)中(zhong)(zhong)心(xin)上可(ke)以有各种不(bu)(bu)同的(de)(de)配置,同类规格(ge)的(de)(de)主(zhu)轴转速不(bu)(bu)同的(de)(de)卧式(shi)(shi)加工(gong)(gong)(gong)中(zhong)(zhong)心(xin),主(zhu)轴电(dian)动(dong)机(ji)(ji)功率可(ke)以相差很(hen)大。

建议:采购用户应根据自身典型零件毛坯余量大小、切削能力 (单位时间金属切削量)、要求达(da)到的加工精度、实(shi)际(ji)能配置的刀(dao)具(ju)等(deng)因素综合(he)选择。

(4)主(zhu)轴(zhou)转速与进给速度(du)

需要(yao)高(gao)速(su)(su)(su)切削或(huo)超低速(su)(su)(su)切削时,应关(guan)注(zhu)主轴(zhou)(zhou)的(de)转速(su)(su)(su)范围。特别是高(gao)速(su)(su)(su)切削时,既要(yao)有高(gao)的(de)主轴(zhou)(zhou)转速(su)(su)(su),同时也要(yao)具(ju)备与主轴(zhou)(zhou)转速(su)(su)(su)相匹配(pei)的(de)进给(ji)速(su)(su)(su)度(du)(du)。目前(qian)卧式加工中心高(gao)速(su)(su)(su)化趋势发展很(hen)快(kuai),主轴(zhou)(zhou)从每分钟(zhong)几千转到几万(wan)转,直线(xian)坐标(biao)快(kuai)速(su)(su)(su)移动速(su)(su)(su)度(du)(du)从10—20/min上升(sheng)到80m/min以上,当然其功(gong)能部件如电主轴(zhou)(zhou)、直线(xian)电动机、直线(xian)滚动导轨(gui)、主轴(zhou)(zhou)轴(zhou)(zhou)承等及相配(pei)套的(de)光(guang)栅尺(chi)、刀具(ju)等附件价格也都(dou)相应上升(sheng),甚至很(hen)昂贵。

建(jian)议(yi):采购用户必须根据自身的技术能力(li)(li)和配套能力(li)(li)合理(li)作出卧(wo)式加工(gong)中心的合理(li)选型。

(5)刀(dao)库容量

可以(yi)根据(ju)被加(jia)(jia)(jia)工(gong)(gong)零(ling)件(jian)的(de)工(gong)(gong)艺(yi)分析结果来确定所(suo)需数量,通常以(yi)典型零(ling)件(jian)在(zai)一(yi)次装夹(jia)中所(suo)需刀(dao)(dao)(dao)(dao)具数量来确定刀(dao)(dao)(dao)(dao)库(ku)(ku)(ku)的(de)容(rong)量,卧(wo)式(shi)加(jia)(jia)(jia)工(gong)(gong)中心以(yi)选用40把(ba)刀(dao)(dao)(dao)(dao)左右的(de)刀(dao)(dao)(dao)(dao)库(ku)(ku)(ku)为(wei)宜。同时要关注最大(da)刀(dao)(dao)(dao)(dao)具直(zhi)径与长度以(yi)及最大(da)刀(dao)(dao)(dao)(dao)具重量等。用于FMC或FMS的(de)卧(wo)式(shi)加(jia)(jia)(jia)工(gong)(gong)中心,应选择(ze)大(da)容(rong)量刀(dao)(dao)(dao)(dao)库(ku)(ku)(ku),甚至配置可交换刀(dao)(dao)(dao)(dao)库(ku)(ku)(ku)。

建议:普通卧(wo)式加工中心选择(ze)40把刀(dao)左(zuo)右(you)的刀(dao)库即够用(yong),用(yong)于FMC或FMS的卧(wo)式加工中心应(ying)选择(ze)大容(rong)量刀(dao)库。

3我需要选(xuan)用什么(me)精度(du)的卧式加工中心(xin)?——精度(du)的选(xuan)定

加工(gong)中心的(de)(de)(de)(de)精(jing)(jing)度(du)(du)(du)(du)等级主(zhu)(zhu)要根据典型零件关(guan)键部(bu)位(wei)(wei)的(de)(de)(de)(de)精(jing)(jing)度(du)(du)(du)(du)来(lai)确定(ding)。其精(jing)(jing)度(du)(du)(du)(du)主(zhu)(zhu)要包(bao)括定(ding)位(wei)(wei)精(jing)(jing)度(du)(du)(du)(du)、重复(fu)定(ding)位(wei)(wei)精(jing)(jing)度(du)(du)(du)(du)和(he)铣圆精(jing)(jing)度(du)(du)(du)(du),特(te)(te)别(bie)是重复(fu)定(ding)位(wei)(wei)精(jing)(jing)度(du)(du)(du)(du),它反映了坐(zuo)标(biao)(biao)轴的(de)(de)(de)(de)定(ding)位(wei)(wei)稳定(ding)性,是衡量该轴是否稳定(ding)可(ke)靠工(gong)作的(de)(de)(de)(de)基本指标(biao)(biao)。特(te)(te)别(bie)值得注意的(de)(de)(de)(de)是,选型订(ding)货时必须全面分析,不(bu)(bu)能简单(dan)地看产(chan)品样(yang)本所(suo)(suo)列的(de)(de)(de)(de)精(jing)(jing)度(du)(du)(du)(du)数值,因为(wei)标(biao)(biao)准(zhun)不(bu)(bu)同、规定(ding)数值不(bu)(bu)同、检测(ce)方法不(bu)(bu)同,数值的(de)(de)(de)(de)含义(yi)就不(bu)(bu)同。刊物、样(yang)本、合格证所(suo)(suo)列出的(de)(de)(de)(de)单(dan)位(wei)(wei)长(zhang)度(du)(du)(du)(du)上允(yun)许的(de)(de)(de)(de)正负(fu)值(一般为(wei)正负(fu)0.05)常常是不(bu)(bu)明(ming)确的(de)(de)(de)(de),订(ding)货时要特(te)(te)别(bie)注意,一定(ding)要弄(nong)清(qing)是IOS(国(guo)际标(biao)(biao)准(zhun)化组织(zhi)标(biao)(biao)准(zhun))、VDI(德国(guo)标(biao)(biao)准(zhun))、JIS(日(ri)本标(biao)(biao)准(zhun))、NMTBA(美国(guo)机床制造商协会(hui)标(biao)(biao)准(zhun))还是NAS(美国(guo)标(biao)(biao)准(zhun))及GB(中国(guo)标(biao)(biao)准(zhun))等,进而分析各(ge)种不(bu)(bu)同标(biao)(biao)准(zhun)所(suo)(suo)规定(ding)的(de)(de)(de)(de)检测(ce)计算(suan)方法和(he)检测(ce)环境条件,才不(bu)(bu)会(hui)产(chan)生误(wu)解。

铣圆精度(du)是综合评(ping)价(jia)卧式(shi)加(jia)工中(zhong)心有关(guan)数(shu)(shu)控轴的(de)伺服跟(gen)随运动特性和数(shu)(shu)控系统插补功能(neng)的(de)主(zhu)要(yao)指(zhi)标(biao)之一。不论典型(xing)零件是否有此需要(yao),为了将来可(ke)能(neng)的(de)需要(yao)及更好地控制(zhi)精度(du),必须重视这一指(zhi)标(biao)。

要特别(bie)注意区别(bie)加工(gong)(gong)(gong)精(jing)(jing)(jing)(jing)度(du)与机床(chuang)精(jing)(jing)(jing)(jing)度(du)两个(ge)(ge)不同的(de)(de)概念。将生产厂家样本(ben)上(shang)或产品合格(ge)证(zheng)上(shang)的(de)(de)位(wei)置(zhi)精(jing)(jing)(jing)(jing)度(du)当作卧式加工(gong)(gong)(gong)中(zhong)心(xin)的(de)(de)加工(gong)(gong)(gong)精(jing)(jing)(jing)(jing)度(du)是(shi)(shi)错(cuo)误(wu)(wu)(wu)的(de)(de)。样本(ben)或合格(ge)证(zheng)上(shang)标明的(de)(de)位(wei)置(zhi)精(jing)(jing)(jing)(jing)度(du)是(shi)(shi)加工(gong)(gong)(gong)中(zhong)心(xin)本(ben)身(shen)的(de)(de)精(jing)(jing)(jing)(jing)度(du),而加工(gong)(gong)(gong)精(jing)(jing)(jing)(jing)度(du)是(shi)(shi)包括(kuo)卧式加工(gong)(gong)(gong)中(zhong)心(xin)本(ben)身(shen)所允许误(wu)(wu)(wu)差在内的(de)(de)整个(ge)(ge)工(gong)(gong)(gong)艺系(xi)统各种因素所产生的(de)(de)误(wu)(wu)(wu)差总和(he)。整个(ge)(ge)工(gong)(gong)(gong)艺系(xi)统误(wu)(wu)(wu)差产生的(de)(de)原因是(shi)(shi)很(hen)复杂的(de)(de),很(hen)难(nan)用线性(xing)关系(xi)定(ding)量表达(da)。选(xuan)型(xing)时,可参考工(gong)(gong)(gong)序(xu)能力系(xi)数(shu)Cp的(de)(de)评定(ding)方(fang)法来作为机床(chuang)加工(gong)(gong)(gong)精(jing)(jing)(jing)(jing)度(du)的(de)(de)选(xuan)型(xing)依据。一般而言(yan),Cp应大于1.33。

站内高精(jing)密(mi)的几款卧(wo)式加工(gong)中(zhong)心:MH-630B、LH-300A、MH-500B、TH500动柱式卧(wo)式加工(gong)中(zhong)心性能都(dou)不错。

建议:采购用户在挑选不同精(jing)度(du)的(de)卧式加(jia)工(gong)中心时(shi),需要考虑(lv):不同标准对应的(de)单位长度(du)含义(yi);重视铣圆(yuan)精(jing)度(du)指标;区别加(jia)工(gong)精(jing)度(du)和机床精(jing)度(du)。

4我应该(gai)选择哪(na)种数(shu)控系统(tong)?——数(shu)控系统(tong)的选定

数(shu)控(kong)系(xi)(xi)(xi)(xi)统(tong)(tong)(tong)(tong)功(gong)能(neng)分(fen)为基(ji)本功(gong)能(neng)与(yu)选(xuan)(xuan)(xuan)择(ze)功(gong)能(neng),可以从操(cao)作(zuo)方(fang)(fang)式(shi)(shi)、用(yong)(yong)户(hu)功(gong)能(neng)、控(kong)制方(fang)(fang)式(shi)(shi)、驱(qu)动形式(shi)(shi)、反馈形式(shi)(shi)、接口(kou)形式(shi)(shi)、检测(ce)与(yu)测(ce)量、报警与(yu)提(ti)(ti)示(shi)、故障诊断等(deng)方(fang)(fang)面综合衡量。基(ji)本功(gong)能(neng)是(shi)必(bi)须(xu)提(ti)(ti)供(gong)的(de),而只(zhi)有当用(yong)(yong)户(hu)选(xuan)(xuan)(xuan)择(ze)了选(xuan)(xuan)(xuan)择(ze)功(gong)能(neng)后,厂(chang)家才会另(ling)行提(ti)(ti)供(gong)并另(ling)行加(jia)(jia)价(jia),且定价(jia)一般较高(gao)。总体而言(yan),数(shu)控(kong)系(xi)(xi)(xi)(xi)统(tong)(tong)(tong)(tong)的(de)功(gong)能(neng)一定要(yao)(yao)根据加(jia)(jia)工中(zhong)心的(de)性能(neng)需要(yao)(yao)来选(xuan)(xuan)(xuan)择(ze),订(ding)购时(shi)既(ji)要(yao)(yao)把需要(yao)(yao)的(de)功(gong)能(neng)订(ding)全,不(bu)(bu)能(neng)遗漏,同时(shi)避免(mian)使用(yong)(yong)率不(bu)(bu)高(gao)而造成浪费(fei),还需注(zhu)意各(ge)功(gong)能(neng)之(zhi)间的(de)关联(lian)性。另(ling)一方(fang)(fang)面,在可供(gong)选(xuan)(xuan)(xuan)择(ze)的(de)数(shu)控(kong)系(xi)(xi)(xi)(xi)统(tong)(tong)(tong)(tong)中(zhong),如SIEMENS系(xi)(xi)(xi)(xi)统(tong)(tong)(tong)(tong)、FANUC系(xi)(xi)(xi)(xi)统(tong)(tong)(tong)(tong)、国产华中(zhong)数(shu)控(kong)系(xi)(xi)(xi)(xi)统(tong)(tong)(tong)(tong)等(deng),性能(neng)高(gao)低(di)差别很大,价(jia)格(ge)亦(yi)相(xiang)差很大,进口(kou)系(xi)(xi)(xi)(xi)统(tong)(tong)(tong)(tong)或国产系(xi)(xi)(xi)(xi)统(tong)(tong)(tong)(tong)亦(yi)决定其价(jia)格(ge)的(de)高(gao)低(di)。总体上(shang)来看,法(fa)兰克系(xi)(xi)(xi)(xi)统(tong)(tong)(tong)(tong)性价(jia)比(bi)(bi)比(bi)(bi)较高(gao),国内(nei)卧(wo)(wo)式(shi)(shi)加(jia)(jia)工中(zhong)心使用(yong)(yong)比(bi)(bi)例比(bi)(bi)较高(gao)。站内(nei)卧(wo)(wo)式(shi)(shi)加(jia)(jia)工中(zhong)心使用(yong)(yong)法(fa)兰克数(shu)控(kong)系(xi)(xi)(xi)(xi)统(tong)(tong)(tong)(tong)的(de)也比(bi)(bi)较多,比(bi)(bi)如MH-800B 、 LH-500B都是(shi)比(bi)(bi)较好(hao)的(de)选(xuan)(xuan)(xuan)择(ze)。多台卧(wo)(wo)式(shi)(shi)加(jia)(jia)工中(zhong)心选(xuan)(xuan)(xuan)型时(shi),应尽可能(neng)选(xuan)(xuan)(xuan)用(yong)(yong)同一厂(chang)家的(de)数(shu)控(kong)系(xi)(xi)(xi)(xi)统(tong)(tong)(tong)(tong),这样(yang)操(cao)作(zuo)、编程、维修都比(bi)(bi)较方(fang)(fang)便(bian)。

建议:法兰克数控系统性价比比较高,多台卧式加工中心选型尽量选用同一厂家的数控系统。

坐标(biao)轴数(shu)和联动轴数(shu)均(jun)应满足典型零件加(jia)(jia)工(gong)要求(qiu)。一般情况下(xia),同厂家、同规格(ge)、同等(deng)精度的(de)卧式(shi)加(jia)(jia)工(gong)中(zhong)心,增(zeng)(zeng)加(jia)(jia)一个标(biao)准坐标(biao)轴,价格(ge)约增(zeng)(zeng)加(jia)(jia)30%—50%。尽(jin)管增(zeng)(zeng)加(jia)(jia)坐标(biao)轴数(shu)可以强化加(jia)(jia)工(gong)中(zhong)心的(de)功(gong)能,是机床(chuang)上档次的(de)标(biao)志之一,但最终还是要在工(gong)艺(yi)要求(qiu)和资金条件下(xia)平衡决定。

(2)工作台

卧式(shi)加工(gong)(gong)中心可配置(zhi)用(yong)于分度(du)(du)的(de)(de)回转工(gong)(gong)作(zuo)台(tai)和(he)数控(kong)回转工(gong)(gong)作(zuo)台(tai),后者能够实(shi)现任意分度(du)(du),作(zuo)为B轴与其他(ta)轴联(lian)动控(kong)制(zhi)。回转工(gong)(gong)作(zuo)台(tai)配置(zhi)与否以及如(ru)何配置(zhi)必(bi)须以实(shi)际需(xu)要(yao)来确(que)定(ding),以经济(ji)、实(shi)用(yong)为目的(de)(de)。

(3)自动换刀装置 (ATC)

ATC的选(xuan)择主要(yao)(yao)考虑换刀(dao)时间(jian)与(yu)(yu)可靠性(xing)。过分强调(diao)换刀(dao)时间(jian)会使(shi)(shi)加工中心的价格大(da)幅度提(ti)高并使(shi)(shi)故(gu)障(zhang)率上升(sheng)。据统计,加工中心的故(gu)障(zhang)中约有50%与(yu)(yu)ATC有关(guan),因(yin)此,在满足使(shi)(shi)用(yong)要(yao)(yao)求的前提(ti)下,尽量(liang)选(xuan)用(yong)可靠性(xing)高的ATC,以(yi)降低故(gu)障(zhang)率和整机成本

(4)必要(yao)的附件、配套件

选型(xing)时,还(hai)应注意选用(yong)一些配(pei)套(tao)件及附(fu)件,尽量(liang)避(bi)免因缺少一个几万元就(jiu)能购买(mai)的(de)附(fu)件而影响卧式加工(gong)(gong)中(zhong)心的(de)正(zheng)常(chang)运(yun)(yun)行。慎(shen)重选择刀(dao)(dao)(dao)柄(bing)和刀(dao)(dao)(dao)具(ju)也(ye)是(shi)保(bao)证卧式加工(gong)(gong)中(zhong)心正(zheng)常(chang)运(yun)(yun)行的(de)关键,最佳的(de)选择办(ban)法应是(shi)根据(ju)典型(xing)零件所需(xu)的(de)品种和数量(liang)来确定,并在使用(yong)中(zhong)陆续添置(zhi)。在卧式加工(gong)(gong)中(zhong)心的(de)构成中(zhong),排屑装置(zhi)、防护装置(zhi)和对(dui)刀(dao)(dao)(dao)装置(zhi) (如刀(dao)(dao)(dao)具(ju)预调仪)等均是(shi)必(bi)需(xu)的(de),对(dui)一些尽管不(bu)是(shi)必(bi)需(xu)的(de)配(pei)套(tao)件,但如果价格不(bu)高,对(dui)使用(yong)带来很多方便,也(ye)应尽量(liang)选用(yong),如附(fu)件铣(xian)头、储刀(dao)(dao)(dao)料架、运(yun)(yun)刀(dao)(dao)(dao)具(ju)车(che)、装卸器等。

建(jian)议:配(pei)件(jian)越高,能实现(xian)的功能越多,但价格也越贵,采购(gou)用(yong)户需(xu)要根据加工需(xu)求酌情(qing)选配(pei)。

7卧(wo)式(shi)加工中心选型时(shi)还有什(shen)么其他需要(yao)注意(yi)的(de)?——需要(yao)注意(yi)的(de)一些问题

(1)结构设计

加工中心对其(qi)(qi)床身(shen)、立柱、工作台、主轴(zhou)以及(ji)刀库等(deng)功能部件(jian)的(de)(de)结(jie)构设(she)计有着很高(gao)的(de)(de)要(yao)求(qiu),以达到其(qi)(qi)高(gao)强度(du)、高(gao)刚(gang)度(du)、高(gao)抗(kang)振性和稳(wen)定性的(de)(de)目(mu)的(de)(de)。选型时,应特别注意(yi)把其(qi)(qi)结(jie)构作为一项重(zhong)要(yao)的(de)(de)具体内(nei)容来进行要(yao)求(qiu)与考虑。

(2)功能与加(jia)工的(de)适应性

虽然(ran)加工(gong)中心(xin)(xin)可(ke)以(yi)进(jin)行钻、扩、铣、镗、铰、攻(gong)螺纹乃至车削 (如车铣复合加工(gong)中心(xin)(xin))等(deng)多种(zhong)加工(gong),但是在(zai)具体(ti)选择(ze)时,还应根(gen)据具体(ti)需要(yao)来(lai)考虑机床的功能与加工(gong)是否相(xiang)适应等(deng)问题。要(yao)注意(yi)以(yi)下几点:

A、复杂曲(qu)线(xian)加工时,要(yao)考(kao)(kao)虑(lv)(lv)CNC是否有(you)所需要(yao)的(de)(de)曲(qu)线(xian)插补(bu)功能,或(huo)选择什么方式(shi)逼(bi)近加工曲(qu)线(xian)并保(bao)证所要(yao)求(qiu)的(de)(de)表面(mian)粗糙(cao)度。三(san)维加工时,要(yao)考(kao)(kao)虑(lv)(lv)选择适合的(de)(de)刀具(ju)结(jie)构(gou),还要(yao)考(kao)(kao)虑(lv)(lv)程序编(bian)(bian)制(zhi)能力,如有(you)必(bi)(bi)要(yao)则必(bi)(bi)须配备自(zi)动编(bian)(bian)程装置或(huo)后(hou)置处(chu)理编(bian)(bian)程装置。

B、需(xu)要(yao)进行螺(luo)纹(wen)(wen)切削(xue) (非攻螺(luo)纹(wen)(wen)方式)时,不仅要(yao)看是(shi)(shi)否(fou)有(you)螺(luo)纹(wen)(wen)切削(xue)功(gong)能、螺(luo)旋线插补功(gong)能和(he)主(zhu)轴转动(dong)与(yu)进给(ji)同步功(gong)能,还要(yao)考虑(lv)(lv)机床是(shi)(shi)否(fou)有(you)径向进给(ji)装置(zhi)(zhi)、是(shi)(shi)否(fou)有(you)主(zhu)轴在旋转方向上任(ren)意角度(du)位置(zhi)(zhi)准确定(ding)位功(gong)能。否(fou)则,仅在数控系统中用(yong)了螺(luo)纹(wen)(wen)切削(xue)功(gong)能仍然无法(fa)进行螺(luo)纹(wen)(wen)切削(xue)C、采用(yong)金刚铰、浮(fu)动(dong)镗和(he)挤压加工(gong)等(deng)特种加工(gong)时,既要(yao)考虑(lv)(lv)适(shi)宜(yi)的(de)自动(dong)换刀(dao)的(de)条件,又(you)要(yao)考虑(lv)(lv)选择合适(shi)的(de)刀(dao)具结构和(he)切削(xue)用(yong)量,应尽可(ke)能在购(gou)(gou)买主(zhu)机时一并(bing)购(gou)(gou)置(zhi)(zhi)部分易损部件及(ji)其他附(fu)件等(deng)。

D、如果有应用DNC、FMS、CIMS等的规划,或(huo)要进行网络制造,则要注意通(tong)信(xin)功能(neng),应选择具有RS—232、RS—485甚至(zhi)MAP网络通(tong)信(xin)、CAN总线(xian)等接(jie)口的系统。

(3)运转的可靠(kao)性

卧式加工中心运转的可靠性决定了其质量好坏。数控系统由于某一块插件板故障造成停机数月的现象屡见不鲜,一个传感器失效造成机床丧失部分功能的现象也多有发生。所以在选型过程中,应采取对老用户进行走访等方式,更多一些了解所选卧式加工中心的使用情况。

建议:采(cai)购用(yong)户在选型时,需要对卧式加工(gong)中心(xin)整(zheng)体的结(jie)构设计、可靠(kao)性(xing)以(yi)及价加工(gong)适(shi)应性(xing)有(you)客观的认识。
