定制CNC加工自动车床52型方孔弹簧夹头

我们使用CNC车床加工毛坯,然后采用真空炉淬火以避免脱碳。最终内孔研磨在坐标磨床上完成,分辨率为0.005 mm。槽在淬火后切割,以防止变形。

客户将图纸发给我们加工的三大理由

1. 批次可追溯质量。 每个炉号和批次均有记录。如果您需要将零件追溯到其材料批次,我们可在数分钟内完成。记录保存5年。

2. 每批次附检验报告。 每次发货均附带尺寸报告。内孔ID、外径、硬度和槽宽均经测量并记录在案。您的来料检验不会出现意外。

3. 同一工厂完成CNC + 冲压 + 弹簧 + 散热器。 夹头并非您唯一采购的零件。我们还在同一厂区内生产弹簧、冲压件和散热器。供应商更少、邮件更少、质量标准统一。

应用领域

25型圆孔夹头是批量车削加工的主力工具。常见应用包括:

  • 钟表零件自动车床 – 小齿轮、齿轮、摆轮轴。淬火内孔在数千次循环中保持严格公差。
  • 医疗器械制造 – 小型骨螺钉、牙种植体基台。0.005 mm内孔重复精度保证螺纹切削的一致性。
  • 电子连接器插针 – 黄铜和铍铜插针,直径1–5 mm。夹头夹持时不损伤表面。
  • 紧固件生产 – 螺钉毛坯和铆钉。淬火钢可抵抗不锈钢等磨蚀性材料带来的磨损。
  • 汽车燃油喷射器部件 – 针阀和喷嘴。内孔光洁度可防止导致泄漏的微划痕。

在上述所有应用中,夹头是原材料棒料与成品零件之间的最后一道环节。一旦夹头失效,整批零件即报废。这就是我们坚持淬火+研磨,而非简单车削后直接发货的原因。

客户下单前常见问题

问:起订量是多少? 答:无起订量。打样可做1件,批量可扩展至10,000件,工艺不变。单件需支付少量调机费,但100件以上单价大幅下降。

问:如何保证淬火后0.005 mm的公差? 答:我们在热处理后研磨内孔,而非之前。毛坯车削时内孔预留0.2 mm余量。淬火后研磨至最终尺寸,消除热处理步骤产生的变形。每个内孔均使用气动量仪检测。

问:典型交期是多久? 答:打样7个工作日,批量生产15个工作日。如需加急,标准材料如65Mn可在5天内完成。我们承诺的交期一定可以兑现。

问:能否提供材质证明? 答:可以。我们提供原材料钢厂证书及自有热处理报告,显示淬火温度和硬度曲线。每笔订单均免费附带。
