定制CNC夹头制造

我们在热处理后采用CNC磨削加工内孔和锥面,确保几何精度一致。我们绝不省略磨削工序。如需特殊槽型、键槽或顶出孔,我们在磨削后使用线切割加工。

客户选择将图纸发给我们加工的三大理由

1. 批次可追溯质量。 每个批次均配有炉号、材料批号和工艺卡。如果您的装配线上出现问题,我们可以追溯到确切的热处理周期和砂轮。随货附完整追溯报告。

2. 每批次检测报告。 我们不只是口头承诺"会检测"。您将收到一份包含内孔、锥面、螺纹中径和跳动度实际测量值的尺寸报告,由QC工程师签字确认。关键尺寸附Cpk值。如需第三方检测(SGS、TÜV),我们可按成本价安排。

3. 同一工厂完成CNC加工+冲压+弹簧+散热器。 您的夹头不是唯一的零件。您可能还需要夹头拉紧弹簧、冲压保持板或主轴电机散热器。我们可在同一厂区内完成全部制造。一张采购订单、一套质量体系、一个交货日期。这缩短了您的供应链,减少了检验工作量。

应用领域

25型外螺纹加长夹头用于自动车床(走心式和滑动主轴箱式)夹持棒料。典型应用:

  • 钟表零件 – 小齿轮、齿轮、摆轮轴,要求跳动度低于0.005 mm。
  • 医疗器械部件 – 骨螺钉、牙种植体基台、小型手术器械,要求材料可追溯性。
  • 电子连接器 – 接触针、插座端子,表面粗糙度影响镀层附着力。
  • 汽车燃油喷射 – 喷嘴针阀、衔铁,批量一致性在数千件生产中至关重要。
  • 航空航天紧固件 – 小型钛合金和Inconel螺钉,夹头须夹持牢固且不损伤材料。

在上述所有应用中,加长头部可深入导套区域,减少棒料振动并提高同心度。外螺纹设计使夹头可直接安装到主轴鼻端,无需单独的转接套。

客户下单前常见问题

问:起订量是多少? 答:无起订量。我们可以制作一件用于样品测试。批量生产建议至少订购50件以分摊砂轮修整成本,但如果您只需10件,我们也接受。

问:如何控制公差和质量? 答:我们在热处理后磨削内孔和锥面,使用内径千分尺和校准锥度环规测量。跳动度在精密主轴上用千分表检测。每批次附检测报告。尺寸超差即报废,不进行返工。

问:交期多久? 答:样品(1-10件)7-10个工作日。批量生产15-20个工作日。如需加急,可分批交货,首批20%在5天内发出。空运费由您承担,我们负责订舱。

问:是否提供材质证明? 答:提供。我们提供原材料钢厂证书、含硬度值的热处理证书,以及如指定电镀则附电镀证书。所有证书均为英文,随货附上。
