国内数控机床发展概括数控机床是由美国发明家约翰帕森斯上个世纪发明的。随着电子信息技术的发展,世界机床业已进入了以数字化制造技术为核心的机电一体化时代,其中数控机床就是代表产品之一。数控机床是制造业的加工母机和国民经济的重要基础。它为国民经济各个部门提供装备和手段,具有无限放大的经济与社会效应。欧、美、日等工业化国家已先后完成了数控机床产业化进程,而中国从20世纪80年代开始起步,仍处于发展阶段。作为现代工业基石的机床产业,是工业经济发展过程中无论如何都不能绕过一个关键性问题,中国机床产业由于先天不足,一直在中高端机床项目发展上落于国外主流水准,正处于一个追赶的过程当中。中国数控机床仍然较为落后。中国数控机床市场巨大,与国外产品相比,中国的差距主要是机床的高速高效化和精密化上,中国正处于工业化中期,即从解决短缺为主的开放逐步向建设经济强国转变,从脱贫向致富转变,煤炭、汽车、钢铁、房地产、建材、机械、电子、化工等一批以重工业为基础的高增长行业发展势头强劲,构成了对机床市场尤其是数控机床的巨大需求。中国机床行业加速转型面临四大制约因素。中国的数控机床技术现在目前最多只能做到五轴联动,并且据有关人士说这个五轴还是作秀成份居多,五轴以上几乎就是全部进口,并且在多点联动的技术上也和国外技术水准存在非常大的差距。国内市场国际化竞争加剧由于中低档数控机床市场萎缩和生产能力过剩,加之国外产品低价涌入,市场竞争将进一步加剧。而高档产品由于长期以来一直依赖进口,国内产品更加面临着国际化竞争的严峻挑战。以技术领先的策略正在向以客户为中心的策略转变经济危机往往会催生大规模的产业升级和企业转型,机床工具行业实现制造业服务化,核心在于要以客户为中心,积极提供客户需要的个性化服务。因此,从简单的卖产品转向提供整体解决方案、从以技术为中心向以客户为中心转变成为当今的趋势。中国的产品与中国市场需求反差较大,产品结构亟待快速调整中国机床行业虽然保持多年持续快速发展,但是产业和产品结构不合理的现象依然存在,整个行业大而不强,高档产品还大量依赖进口。国产机床的国内市场占有率虽然已经有一定的提高,但是高档数控机床、核心功能部件在国内市场占有率还很低,全行业替代进口的潜力非常巨大。企业技术创新模式有待完善由于中国机床企业的地位、工业化水平和品牌影响力在逐步提升,要成为工业强国,其技术的获得再也不能依赖别人。过去,中国走了一条从模仿到引进的道路,从现在开始必须走自主创新的道路。企业技术遇到新的封锁,建立自主、新型、战略性的产学研创新模式是支撑产品结构调整技术来源的惟一途径。中国数控机床行业将延续结构调整的势头,不断以新产品、新亮点占领更大市场。数控切割机床按切割方式可分为火焰切割和等离子切割两大类。随着下游行业需求的不断提高,对数控机床配件提出了更大的需求和更高的要求。东北地区发展不快,其他地方的发展也比较缓慢。三是调结构促转型取得成效。专家认为面对金融危机,广大企业应不断调整结构、提高质量、增加品种及推动产业升级,再加上企业加强管理,降低费用,所以企业效益明显好转。数控切割机床装饰性发展趋势可见一斑,数控切割机床更多的是强调在机械性能、操作简便、价格经济、加工精度稳定等方面。在金属材料加工日益要求普及和批量化的今天,数控切割机床除了要满足上述功能性外,还要具有多切割方式的适用性。国内数控机床企业为了提高自身实力,更快地拓展国际市场,将采取多种手段加快和国外企业的融合以提高产品质量、提高竞争力。在继续开拓美国、日本等国家市场的同时,在东南亚、中东、俄罗斯、欧洲、非洲等也全面开花。据了解,当前金属切割数控机床行业运行具有以下几个特点一是外销企业困难较大。从规模以上企业来看,以内销为主的品牌企业发展势头较好。没有品牌的中小企业发展比较困难。二是各地区发展不够均衡,浙江、山东、河北、北京以及四川发展比较快,广东的民营企业发展也较快。数控切割机床行业多数企业都是依靠降低产品售价来获得市场,造成的后果是产品价格低、附加值低、利润低,企业没有足够的资金持续发展。随着产业的发展和竞争的升级,提高产品技术含量,拥有自主的专利、设计,注重品牌的打造和营销才是企业长期发展的最佳选择。中国机床行业在过去几年实现了持续超高速的发展,一直到2011年上半年,需求仍很旺盛,但是从下半年开始,需求增势明显趋缓,新增订单剧烈下滑,经济效益状况逐渐趋于严峻,利润率持续下降。在十二五期间,国家实施积极的财政政策和稳健的货币政策,随着科技进步、产品升级以及国家重点工程、地方投资项目的不断推进,国民经济各行业对机床工具产品的需求水平将进一步提高,国防现代化对高水平机床的需求将更为迫切,市场需求将向更高层次发展,新一轮的市场竞争也将更加激烈。由于行业景气度低迷,下游制造型企业对机床需求下降,所以我国机床行业一直处于低迷状态,升级转型成为行业近几年的关键词,经济型数控机床则成为振兴装备制造业的重点之一。我国的铸造机床产业取得了一定的成绩,但是其发展仍然面临着许多制约性问题,技术创新一直是国内铸造机床行业的硬伤。与国外的铸造机床产业相比,我国的铸造机床产业在制造工艺水平上明显落后,这使得其在核心运行部件的技术水平和运行速度、产品精度保持性以及机床的可靠性上有着明显的不足。我国铸造机床企业缺乏自主创新和基础理论研究的意识与能力,这就制约了我国铸造机床技术的发展,要改变这种现状,就要深入研究用户行业产品工艺的特点和要求,结合工艺特点开发出高水平加工设备,同时,还要注重基础理论工作的研究,这样才能让我国铸造机床产业在不久的将来有更好的发展。国家出台的一系列政策,大力建设新兴企业,高新技术企业,抓住了这一时机,企业内部出台了调整与振兴、自主创新等一系列政策,升级企业机床技术,严格保证产品质量,为加快铸造机床行业的发展提供了良好的环境跟市场。机床工具行业作为国家基础性和战略性产业,在十二五规划中,已明确将自主创新战略作为最主要的一个组成部分,着重强调了要以技术创新工程来支撑和引领行业发展。我国机床工具行业的发展必须立足于自主创新,通过自主研发原始创新、引进技术消化吸收再创新、集成现有技术创新等方式,实现关键技术突破和产业升级。构建和完善以企业为主体、以市场为导向、产学研用相结合的技术创新体系坚持加大研发费用投入加强关键技术、共性技术的研究,力争在基础和共性技术攻关上有所突破,提高产品开发技术水平。技术发展高速、精密、复合、智能和绿色是数控机床技术发展的总趋势,近几年来,在实用化和产业化等方面取得可喜成绩。主要表现在1、机床复合技术进一步扩展随着数控机床技术进步,复合加工技术日趋成熟,包括铣车复合、车铣复合、车镗钻齿轮加工等复合,车磨复合,成形复合加工、特种复合加工等,复合加工的精度和效率大大提高。一台机床就是一个加工厂、一次装卡,完全加工等理念正在被更多人接受,复合加工机床发展正呈现多样化的态势。2、数控机床的智能化技术有新的突破,在数控系统的性能上得到了较多体现。如自动调整干涉防碰撞功能、断电后工件自动退出安全区断电保护功能、加工零件检测和自动补偿学习功能、高精度加工零件智能化参数选用功能、加工过程自动消除机床震动等功能进入了实用化阶段,智能化提升了机床的功能和品质。3、机器人使柔性化组合效率更高机器人与主机的柔性化组合得到广泛应用,使得柔性线更加灵活、功能进一步扩展、柔性线进一步缩短、效率更高。机器人与加工中心、车铣复合机床、磨床、齿轮加工机床、工具磨床、电加工机床、锯床、冲压机床、激光加工机床、水切割机床等组成多种形式的柔性单元和柔性生产线已经开始应用。4、精密加工技术有了新进展数控金切机床的加工精度已从原来的丝级(0.01mm)提升到微米级(0.001mm),有些品种已达到0.05μm左右。超精密数控机床的微细切削和磨削加工,精度可稳定达到0.05μm左右,形状精度可达0.01μm左右。采用光、电、化学等能源的特种加工精度可达到纳米级(0.001μm)。通过机床结构设计优化、机床零部件的超精加工和精密装配、采用高精度的全闭环控制及温度、振动等动态误差补偿技术,提高机床加工的几何精度,降低形位误差、表面粗糙度等,从而进入亚微米、纳米级超精加工时代。5、功能部件性能不断提高功能部件不断向高速度、高精度、大功率和智能化方向发展,并取得成熟的应用。全数字交流伺服电机和驱动装置,高技术含量的电主轴、力矩电机、直线电机,高性能的直线滚动组件,高精度主轴单元等功能部件推广应用,极大的提高数控机床的技术水平。发展问题国内数控机床的需求日益增长,数控机床的发展推动了数控机床功能部件的创新升级。目前我国高档数控机床关键功能部件工业还不能满足国内需要,国内数控功能部件产业主要存在以下问题。1、适应性和满足度远达不到市场需求从当前我国数控机床的发展趋势来看,国产功能部件的适应性和满足度远远达不到市场的需求。主要表现在1)我国功能部件的产品水平和国外有一定差距。我国生产的功能部件多数以劳动密集型为主,技术含量低,难以适应国产数控机床的发展速度和技术要求,特别是高档数控机床。2)我国功能部件开发能力较弱,新产品开发速度慢,多数功能部件需要与国外合作开发、合作生产、合资经营,甚至只能组装。虽然这两年形势有显著变化,但高技术、最新型的功能部件,我国尚在研制过程中,市场占有率前景依然不容乐观。2、我国数控功能部件生产企业的规模小据统计我国固定资产达到1000万元以上的功能部件生产企业有70多家,占全部生产企业的10以下。我国的功能部件生产企业的出身有4种一是从研究院所、大专院校以技术支撑发展而来的企业,可称为院所型。这些企业的特点是有一定技术基础和人才基础,有多项技术的发展潜力,但生产手段较弱,难以在短时间内形成产业规模,在成本、营销、服务等方面也存在一些差距二是从主机厂逐步独立、分离出来的以生产某种功能部件为主发展起来的企业,可称之为主厂型。这些企业在生产能力、工艺水平和使用经验上都可以适应市场需求,在一定程度上可以形成规模,但由于其与原主机厂有着千丝万缕的联系,在竞争中往往让用户产生疑虑,影响其市场开拓,同时,其开发能力也有一定的局限性,所以难以形成著名品牌三是在江浙一带大量涌现出的民营企业,可称之为民企型。这些企业主要以劳动密集型、单一品种为主,如护链罩、拖板、喷油管、排屑器、照明设备等。由于竞争激烈,其质量和价格都能满足中低档数控机床的市场需要。虽然这些品种的高档产品尚不能制造,还需依赖进口,但在很大程度上,适应了我国数控机床发展的总体需求还有一部分外商合资企业或独资企业生产部分较高水平的功能部件,但批量较小,且没有独立的技术开发能力,难以成为功能部件的主体和主流。3、核心零部件大量依靠进口中国数控机床行业的发展令人瞩目,2008年中国数控机床工具工业完成工业总产值34723亿元,产品销售产值3348.3亿元,同比分别增长27.5和26.0。20022008年中国是世界机床第一消费国和第一进口国。但行业迅速发展的背后,一个不能忽视的事实是,我国关键零部件生产依然受制于人,出现了利润不高、产品缺乏核心竞争力的局面。4、缺乏高技术含量威胁产业安全我国机床出口连年保持增长的喜人态势,不过量增价减的尴尬直接反映出我们的技术水平。大量核心技术的缺乏和关键零部件的依赖直接影响到我国的机床产业安全。因此,我们需要强化预警工作意识,凝聚行业智慧和力量,维护产业安全。DomesticCNCmachinetoolsdevelopmentNcmachinetoolsisbyAmericaninventorJohnparsons,inventedinlastcentury.Alongwiththedevelopmentofelectronicinformationtechnology,theworldmachinetoolindustryhasenteredtheeraofdigitalmanufacturingtechnologyasthecoreofelectromechanicalintegration,oneofncmachinetoolsis
