定制CNC加工自动车床46型六角孔加长夹头

每只夹头均从精密磨削的毛坯开始。我们在CNC自动车床上完成外形车削,然后在专用内圆磨床上磨削内孔和锥度。发黑层在淬火后施加,在不改变关键尺寸的前提下增加耐腐蚀性。对于大批量订单,我们使用多主轴自动车床,将单件节拍控制在30秒以内。

客户向我们发送图纸的三个理由

1. 批次可追溯的质量。 每炉材料都有唯一的批号。该批号从进料检验到最终硬度测试全程跟随钢材。如果您需要将失效零件追溯到原材料,我们可以向您展示准确的钢厂质保书和热处理曲线。无需猜测。

2. 每批次附检测报告。 您无需主动索取质量数据。我们会自动发送。每批次随货附尺寸检测报告,涵盖内孔尺寸、锥度角、圆度和同心度。每个样件三个位置的硬度读数均包含在内。如果您需要带SPC控制图的100%全检,我们也可以做到——只需在采购订单上注明即可。

3. 一家工厂完成CNC加工、冲压、弹簧和散热器。 您的夹头并非孤立存在。它安装在主轴中,通常配合弹簧推料器或冲压保持架使用。我们在同一厂房内制造所有这些零件。这意味着一个采购订单、一个交货日期、一个质量标准。您无需再为协调三家互不沟通的供应商而头疼。

这些零件的应用领域

本系列定制CNC夹头专为高速、高精度夹持工况而设计,应用于:

  • 走心式车床,用于医用骨钉、牙种植体和手表齿轮轴——跳动量必须低于0.005 mm。
  • 自动棒料送料机,用于紧固件生产,夹持直径1 mm至42 mm的六角、方型和圆型棒料。
  • 磨床主轴,用于刀柄和导向轴套,发黑层可防止夹头外径发生咬合。
  • 弹簧卷绕机和线材成型机,夹头须夹持线材而不损伤表面。
  • 电子行业散热器加工线,频繁换刀要求夹头在数千次循环后仍能保持定位精度。

淬火发黑处理并非仅为外观。它降低了夹头与主轴锥孔之间的摩擦,防止高速分度时发生卡死。同时,相比普通磨削表面,发黑层排屑和排液性能更佳,延长主轴鼻端的使用寿命。

客户下单前常问的问题

问:真的没有起订量吗? 答:是的,没有起订量。我们经常为配合测试发货单件打样产品。单件订单的单件价格较高,因为装夹调试和检验时间占主导。但如果您发送图纸给我们,我们会如实报价——无论您需要一件还是五万件。

问:如何保证定制夹头的公差? 答:我们按照您的图纸加工,同时还会根据您指定的实际主轴锥度对零件进行校验。如果您提供锥度角和配合零件编号,我们会使用气动量仪和三坐标测量机验证内孔和锥度。检测报告显示的是实测值,而非仅仅是合格/不合格的盖章。

问:你们的常规交期是多久? 答:对于GCr15等标准材料配合发黑处理,打样产品7–12个工作日发货。500件以上的批量生产需15–20个工作日。如需加急,我们可提供3天打样服务,加收20%费用。

问:你们提供材质证明吗? 答:提供。每批次均包含原材料钢厂质保书,以及我们自检的硬度和化学成分测试结果。对于航空航天或医疗订单,我们可提供包含批号和热处理记录的完整可追溯性文件。
