开篇

您的图纸决定公差,我们的任务就是精准达标。我们从实心棒料加工您的ER50弹簧夹头和夹头螺母,而非使用可能存在内部气孔的铸造毛坯。每一处螺纹均为切削加工,每一处锥面均经磨削,每一处同轴度在零件出厂前均经过验证。

我们不会交付连自己主轴都不愿装夹的零件。图纸上标注的,我们逐一测量;图纸上未标注的,我们先与您确认。

  • 同轴度:鼻端 ≤ 0.005 mm TIR
  • 螺纹精度等级:6H / 6g
  • 表面粗糙度:锥面及内孔 Ra 0.4 µm
  • 定制批次交期:15-20个工作日
  • 无起订量——一件或一千件,工艺管控标准一致

定制CNC夹头卡盘套装

我们使用马扎克(Mazak)和斗山(Doosan)带动力刀具的CNC车床加工本体,随后在斯图特(Studer)内圆磨床上精磨锥面。螺纹采用CNC螺纹磨床磨削,而非板牙套丝。这就是夹头真正夹持精准与摆动晃动的本质区别。

客户选择将图纸交给我们的三大理由

1. 批次可追溯的品质管控 每个批次均配有独立炉号和工单。我们记录材料证书、机床参数和操作人员签名。如果六个月后您的装配线上出现问题,我们可以精确追溯到具体班次和刀片。贸易公司做不到这一点。

2. 每批附检测报告 每次发货均附带尺寸检测报告,列出锥角、螺距、同轴度和硬度的实测值。我们不只是说"在公差范围内",而是用数据说话。对于关键航空航天或医疗批次,可根据要求提供CMM点云数据。

3. 同一工厂完成CNC加工 + 冲压 + 弹簧 + 散热器 您的弹簧夹头并非孤立零件。它需要与拉杆弹簧、冲压保持板或高速主轴壳体中的散热器配合使用。这些我们都在同一厂区内制造。您只需提供一套图纸,我们统筹协调各工序,您收到一次合并发货。供应商更少,借口更少,延误更少。

应用领域

我们的定制CNC弹簧夹头正运行在那些让廉价刀具不堪重负的生产环境中:

  • 走心式车床——用于医用骨螺钉和牙科种植体,0.005 mm的跳动直接决定零件合格与否。
  • 多轴自动车床——汽车燃油喷射器生产线,ER50夹头可夹持直径达34 mm的棒料,承受高频夹持循环。
  • 刀具预调仪和磨削夹具——夹头螺母必须在每次夹紧时重复定位到相同位置,因此我们磨削螺纹牙侧以保证一致的导程。
  • 机器人去毛刺单元——带键槽的重型夹头本体可防止侧向载荷下旋转。
  • 高速主轴维修厂——用我们的产品替换磨损的OEM夹头,按原图纸加工,但钢材更优。

如果您的应用涉及夹持圆棒料、通过内孔输送切削液,或10,000+ RPM高速旋转,这就是您需要的零件。

客户常见问题

问:起订量是多少? 答:无起订量。我们先加工一件原型供您测试,确认满意后再批量生产至5,000件。单价随数量递减,但品质管控流程不变。

问:如何保证公差和品质? 答:我们在同一装夹中磨削锥面和内孔,消除累积误差。每只夹头均通过马波斯(Marposs)量仪检测锥角和同轴度。检测报告随货附上。如有任何尺寸超差,我们自费更换。

问:交期多久? 答:标准定制批次为图纸确认后15-20个工作日。如需样品进行装配测试,可在7天内加急交付。重复订单更快,因为我们保留您的工装和程序文件。

问:能否提供材质证书? 答:可以。我们提供原材料钢厂质保书、热处理报告和硬度检测结果。对于不锈钢或高合金钢,还可提供独立实验室的化学成分分析报告。

发送您的图纸

不要再猜测标准目录夹头是否适配您的主轴。将图纸发给我们,我们会明确告知可达到的公差、价格和交付时间。

  • 12小时内给出正式报价——含刀具成本、单件价格和交期
  • DFM可制造性反馈——如果您的设计存在难以加工的内尖角或成本较高的严苛公差,我们会在您付款前提前告知
  • 无起订量、无隐藏费用——报价即最终发票金额
