开篇

我们按照您的图纸精确加工ER20弹簧夹头。不是从标准毛坯改制,也不是从标准规格修改。我们从棒料开始,将每一个轮廓、槽口和锥度都加工到您指定的尺寸。

每件夹头在发货前均经过验证。我们使用三坐标测量机检测关键锥角、槽宽和同心度。您拿到的是数据,而不仅仅是一个“合格”的印章。

概览: 内孔公差±0.005 mm,表面粗糙度Ra 0.4,交期7–12天,无起订量。一件或一千件,工艺完全相同。

定制CNC夹头延长杆长伸距精密制造

我们使用五轴CNC车削中心加工锥面和内孔。槽口采用慢走丝线切割,避免刀具偏让。热处理在厂内真空炉中完成,硬度曲线由我们控制,而非外协供应商。

客户将图纸发给我们的三大理由

1. 批次可追溯的质量。 每件夹头都有热处理炉批号。我们记录炉次周期、材料炉号及最终硬度读数。如果第47号刀具出现问题,我们可以调出确切的批次记录,告诉您硬度、锥度测量值和操作人员。无需猜测。

2. 每批附带检测报告。 您无需主动索取。每批货物均附带尺寸报告,包含锥角、内孔直径、槽宽和同心度的实际测量值。我们使用蔡司三坐标测量机和经校准的气动量仪。报告由质检人员签字,而非软件自动生成。

3. 一家工厂完成CNC加工、冲压、弹簧和散热器。 这是没有中间商的精密制造。您的夹头刀柄组件可能需要弹簧、冲压保持架或主轴驱动散热器。我们全部在同一厂区内完成。您发送一套图纸,获得一份报价、一套质检报告和一次发货。供应商更少,公差累积更少,争议更少。

应用领域

ER20夹头是高速加工中心和CNC车床的主力夹具。典型应用:

  • 铣削主轴刀柄夹持 – 1–13 mm柄径刀具,对跳动敏感的精密加工。
  • 钻孔和铰孔 – 液压夹头过于浪费,而普通钻夹头无法保证同心度的场合。
  • 走心式车床 – 导套和主轴夹头,适用于直径最大20 mm的棒料。
  • 汽车气门座圈加工 – 24/7连续运行的生产线,需要无需重新对刀的重复换刀精度。
  • 航空航天铝材和钛合金加工 – 重径向载荷下不允许刀具松脱的场合。

我们还制造定制ER20变体:加长鼻端用于深腔加工,开槽版本用于内冷通道,以及高夹紧力应用的淬硬钢版本。如果您的图纸标注“ER20但有所改动”,我们都能加工。

客户下单前常问的问题

问:起订量是多少? 答:无起订量。一件我们也报价并生产。单件夹头的单价高于100件,但工艺完全一致。我们不会将小订单与其他客户的工件混批生产。

问:如何保证公差和质量? 答:锥角使用气动量仪测量,而非比较仪。内孔使用经NIST标准校准的内径千分尺测量。每批附带书面检测报告。任何尺寸超差,我们直接报废,绝不发货。

问:定制CNC夹头刀柄的交期是多长? 答:打样(1–5件)为7天。批量生产(50件以上)为10–12天。热处理增加2天,但已包含在上述时间内。我们不会为了保险而报“最长4周”。我们只报能兑现的交期。

问:能否提供材质证明? 答:可以。我们提供原材料钢厂质保书、含实际硬度曲线的热处理报告以及合格证。所有文件均为英文。我们也可以安排第三方检测(SGS或BV),费用由您承担。

发送您的图纸

将PDF或STEP文件发送至 sc@bquq.com。如您已知材料、硬度和数量,请一并注明。如果不知道,我们会根据您的应用场景给出建议。

我们在12小时内回复正式报价。不是“预算范围”,而是每件固定单价、工装费用(如有)和交货日期。

紧急项目,请通过WhatsApp联系 +86 13713157787。我们每周7天、北京时间8:00–22:00在线。
