您的图纸定义零件,我们的CNC机床负责加工。每一根夹头延长杆在离开我们东莞工厂之前,均经过同心度和锥角验证。我们不交付任何未经检验的产品。

我们可根据棒料或您的锻件,制造定制CNC夹头本体、延长杆及长伸距变体。锥度精度可达AT3或更高,表面粗糙度低至Ra 0.4。机加工件标准交期为15-20天。无起订量限制——一件或一千件,工艺控制完全相同。

概览: 关键直径公差±0.005 mm,跳动≤0.005 mm TIR,硬度58-62 HRC(可选),交期15-20天,无起订量,每批附检测报告。

交期标准15-20天,样品7天
文件材质证书、检测报告、批次可追溯性

我们在热处理后对内锥面进行磨削,这是达到AT3精度的唯一途径。我们不对软态毛坯进行磨削。如需更长伸距,我们将延长杆作为一体件加工——无焊接接头,无压配套筒。一体式结构意味着可预测的刚性和无跳动漂移。

客户将图纸交给我们的三大理由

1. 批次可追溯的质量。 每个零件都有唯一的批号。我们记录材料炉号、操作员、刀具补偿值和检测结果。如果您的装配线上出现问题,我们可以精确追溯到具体批次和日期。绝无含糊。

2. 每批附检测报告。 您无需主动索取。每批货物均附带包含实际测量值的尺寸报告——不仅仅是合格/不合格的盖章。锥角、跳动、硬度、表面粗糙度——我们测量对夹头至关重要的所有参数。

3. 一家工厂完成CNC加工+冲压+弹簧+散热器。 夹头不是您采购的唯一零件。我们在同一厂区内还生产金属冲压件、精密弹簧和铝制散热器。一张采购订单、一套质量体系、一个发货点。供应商更少,意外更少。

应用领域

定制CNC夹头延长杆并非标准货架产品。它们应用于需要在保持刚性的同时获得更大伸距的机床。

  • 深腔加工 – 模具加工中,夹头需越过台阶或伸入型腔。
  • 走心式车床 – 用于小直径棒料加工的长伸距导向轴套和夹头。
  • 汽车动力总成 – 加工气门导管、喷油器孔和齿轮轴时,刀具悬伸不可避免。
  • 航空航天结构件 – 钛合金和铝框架的深腔铣削,需要刚性刀柄。
  • 医疗器械植入物加工 – 用于深骨螺钉孔的小直径钻头和铰刀,由细长夹头夹持。
  • 液压阀块 – 交叉钻孔需要夹头伸入200 mm深的孔内。

在所有应用场景中,客户的需求是一致的:夹头能保持刀具笔直、不振动、不增加跳动。这正是我们交付的产品。

客户下单前常问的问题

问:你们真的没有起订量要求吗? 答:是的。无论是单件原型还是批量生产,我们都能加工。单件价格会变化,但工艺控制不会。许多客户先订一件样品进行测试,然后下单500件。

问:锥度和跳动能保证什么公差? 答:锥角精度可达AT3(如您指定可做到AT2)。鼻端跳动≤0.005 mm TIR。对于长伸距延长杆,我们在距鼻端100 mm处保持≤0.01 mm TIR。每件产品均通过三坐标测量机和精密锥度规验证。

问:标准交期是多久? 答:库存材料机加工件为15-20天。如需样品进行装配测试,可在7天内发货。对于批量重复订单,可安排框架交货计划。

问:能否提供材质证书和检测报告? 答:可以。每批产品均附带材质证书(如需可提供EN 10204 3.1或3.2)和尺寸检测报告。记录保存10年。
