    Machining tool inserts

    2017-05-08T18:16:36Z

    The Hoffman Group says its new Garant HB 7010-1 indexable insert features a multi-layer coating system and a gradient carbide substrate. The company claims this CVD coating protects the carbide substrate at high cutting speeds and process temperatures. The coating’s resistance is due to straightened crystal structures and a smooth ...

    击败低效率

    2017-03-15T13:20:59Z

    与供应商合作相适应的工具革新对汽全球车机械工厂提高竞争力极为重要。 福特英国布里真德(Bridgend)发动机工厂一年生产750,000多台柴油发动机。工厂与Mapal进行切削工具合作,帮助工厂实现SPC目标,以及发动机关键组件的精确度。为了这个目标,Mapal工厂已经永久聘请工程师Wayne Keepins。Keepins说,“我们努力帮助Ford实现改进生产力,降低年成本10-15%的目标。” 像很多现代发动机一样,福特公司动力系统采用了轻质铝材缸体,内壁压上烧结贴衬垫,支持移动磨损部件,而Mapal产品很大部分都用于发动机缸体铣削和钻孔作业。该工具公司称,为了解决这个难题,公司专门开发了多步钻孔方案。 组合工具提高生产力 Keepin是说,“为了提高效率、生产力、工具寿命并降低成本,我们不得不走出之前更换钻孔工具的方法,我们必须设计全新的理念。比如,为1.5升和1.6升发动机生产线加工阀座。之前的工序以来3个不同的可转位替换刀片,完成4个程序。这中操作包括加工混合进气口、进气门座半加工、气门导管领航,阀座完成,以及引导。我们开发了一种新的组合工具,能够把3个工具降低到2个,降低了成本、启动时间,而且提高了生产力。” Mapal说,取消单程库存材料,就不需要单独的气口混合和阀座工具。新的组合工具降低了循环时间。从64秒降低到34秒,而且切削工具固定时间减少了30%,每年能够减少800次工具更换次数。 公司还开发了其他工具,解决发动机内在缸体加工问题。在JLR V8发动机生产线上,工具后侧受到木屑颗粒污染的时候,连杆大端孔流程就可以阻止钻具导料块上的木屑。为了解决这个问题,Mapal开发了一个双工具流程,替代之前3工具设备。把粗镗工具拿走,并从板材一侧加工整孔,双工具加工降低了衬垫消耗,提高了工具寿命,每年节省5,200英镑(约合64,000美元)。 一部分原因是新工具需要4个衬垫,而不是8个,节约了50%。生产线每年生产145,000个发动机,得益于精准的钻孔机表面抛光,每小时发动机产量提高了,工具更换次数将少了。 粗加工,光洁整理 在铣刀工具更新上,还有一个切削工具专家,那就是Sandvik Coromant公司。公司引进了一个平面铣刀,专门用于不锈钢涡轮增压安装外壳粗加工。涡轮排气装置粗加工的主要难点在于,薄壁组件的外形很复杂,而且夹具(用于振动操作)很精致。Sandvik Coromant公司开发的M612平面铣刀的几何结构非常优良,据说可以消除振动,从而优化面板切削操作。反过来,也可实现较高的金属切削率。 Sandvik Coromant公司汽车应用工厂是Jacques Gasthuys说,“不锈钢将成为涡轮装置的最佳选择,其性能优于传统的铸铁,有助于提高抵抗排气温度(最高可达1,300摄氏度),同时也可以抗腐蚀。” “每年大约生产5,000万个涡轮增压器 — 有铸铁的,也有不锈钢的 — 但是加工不锈钢的成本要高出20倍,因为这些操作非常短,而且刀片寿命不确定,而且磨损不均匀。考虑这些因素,我们的目标就是开发牢固的道具,可以降低组件成本。” 在特点级别为GC4240刀片的客户项目中,使用M612铣刀,周转速可以从212rpm提高到273rpm,切削速度也会从70m/min提高到90m/min,而且给料速度也会从0.13mm/rev提高到0.18mn/rev。同时,切削深度可以达到2.5mm。实验结果显示,M612平面铣刀可以降低每个组件27%的加工时间,而工具寿命增加了172%。 Advances in CBN tooling are introducing new compounds, coatings and geometries to improve tool life 工具的艰难时刻 在汽车硬态切削加工也需要不断提高生产力,降低生产前置时间,以满足成本节约的要求。最新CBN(立方氮化硼)工具采用特殊混合物、高效率涂层及新的几何结构,提高受热、表面加工,抵抗断续切削带来的机械冲击。 有一个很好的例子就是Sumitomo Electric Hardmetal公司新开发的“混合”系列CBN硬态切削刀片。SumiBoron混合物,BNC2010和BNC2020都具有多层,在烧制CBN粉缸体时采用抗热抗磨损微观结构涂层,而底层融合了碳氮化物粘合剂。 此外,公司还开发了一种名为 “Break Master” 的木屑轧碎机,以及用于加工淬火钢的N-FV和N-LV,还有能够提高消除碳化层过程中的碎屑控制。 在对比传统涂层CBN刀片(用于传动轴硬态切削)的试验中,BC2010刀片能够提高230%的工具寿命。此外,当BC2010用于恒速万向节切削的时候(加工过程中会有断续切削),工具寿命可以提高150%。 有了这些优点,用户可以提高材料单个操作战略的生产力优势,可以超过45HRc,因此可以消除研磨和EDM加工。实际上, ...

    研磨霍霍

    2017-01-30T15:49:04Z

    为汽车业生产高质量棱柱机加工件这条路,已经走过了漫漫数年 今天的汽车制造工厂似乎更加钟爱柔性制造系统(FMS)或单元,与专门转运线截然相反。这是因为今天的车型使用寿命比过去的短,因为制造商频繁改进设计,以便提高市场份额。 为了保证FMS的效率和生产率,投资最新CNC机床中心技术就成为必备。最近Starrag UK报道中提到,公司将另一个Heckert水平HEC 400D机床中心提供给顶级供应商 — 第14个现场机床 — 以扩大生产单元,生产各种钢铁和铝悬挂组件。 据Starrag称,这个4轴加工中心在汽车部门广泛应用 — 比如制造商和顶级供应商 — 用于工件的单一加工组合,比如变速箱、连接筒室和阀盖,在用于单元或FMS配置的时候提高效率。 采用模块化途径 在德国机床制造商Heeler公司,理念更趋向机床模块化,尤其是生产气缸体、气缸盖、曲轴、凸轮轴、变速器和底座组件等零部件方面。为了能够应用于各种生产需要,从小型辆缸摩托车发动机,到V12建筑机械发动机,Heller选择可量化生产系统。 据德国汽车制造商协会(VDA)称,2015年在全球生产了7,870万辆乘用车,比前一年增长1.7%。仅仅在德国,就生产了570万辆汽车,增长率近2%。德国的汽车制造商收到逐渐变短的创新循环,以及车型变体多样化的推动。 Heller集团首席营运官Manfred Maier及时了机床制造商对汽车制造商的意义:“对很多汽车制造公司来讲,高度的灵活性能带来最高产量 — 当然投资要尽可能少。减少投资决策与实际生产行动之间的时间也是非常重要的。” 这个理念已经在4轴和5轴机床得到实现,实现直接装在、客户定制,并且在任何时间点都可以连接的程序设计,创造了全自动化制造平台。 According to Starrag, four-axis machining centres are being used by OEMs tier suppliers for single set-up machining of workpieces such as gearboxes, coupling housings, etc 更高的复杂性,更低的产量 机械加工面对种种挑战,比如批量规模不断减少、组件更加复杂,创新技术不断组合,最终实现完整的加工操作。 ...
