这款ER11夹头刀柄对您的钻孔循环有何作用

这是一款数控加工的ER11弹簧夹头刀柄,附带钻头,可直接安装到您的主轴或刀柄上。它可夹持1.0毫米至7.0毫米的圆柄钻头,鼻端跳动精度保证为0.005毫米TIR(总指示跳动),该数值在装配后测量。刀体经过淬火处理,硬度达到58-60 HRC,标准规格产品可在48小时内从我们东莞工厂发货。与紧定螺钉刀柄相比,您将获得刚性更强、重复性更好的夹持力,可消除钻头偏移,并将刀具寿命延长最多30%。

ER11夹头如何实现无跳动夹持刀具

ER11夹头采用锥形外表面,当您拧紧锁紧螺母时,夹头会围绕钻头柄部均匀收缩。我们的刀柄本体由整块42CrMo合金钢坯料加工而成,而非焊接或组装件。锥角经过磨削加工,精度为8度,公差为±0.002毫米。这种精密制造工艺确保夹头完全且同心就位,使您的钻头在20,000 RPM或更高转速下保持真圆旋转。我们在发货前使用千分表对每支刀柄进行测试。

我们用于刀柄本体的材料与热处理工艺

我们选用42CrMo钢材,该材料具有高韧性和耐磨性。经过数控车削和铣削后,我们对表面进行渗碳处理,渗碳层深度为0.8-1.2毫米,然后淬火至58-60 HRC。内孔经过珩磨加工,表面粗糙度达到Ra 0.4 µm。锁紧螺母采用20CrMnTi材料制造,渗碳淬火至60-62 HRC,其螺纹采用滚压而非切削工艺成型,使拧紧操作更顺畅且使用寿命更长。无涂层、无镀层——只有干净坚硬的钢材,可在大量使用冷却液的钻孔应用中保持稳定性能。

为什么整体坯料优于焊接组装刀柄

许多低成本刀柄采用易切削钢甚至冷拉棒材制造,这些材料在受热时容易变形。我们在五轴数控车床上从实心42CrMo坯料加工ER11刀柄本体,然后在专用内圆磨床上磨削锥面。这一工艺消除了残余应力,使刀柄在数千次夹持循环后仍能保持几何精度。如果您将我们的刀柄与铸造或锻造的竞品进行比较,在钻削前100个零件时就能看到差异。

每批发货前的检验流程

每支刀柄均经过100%全检,而非抽检。我们使用三坐标测量机(CMM)验证锥角、内孔直径和同心度。然后,我们将刀柄与标准ER11夹头和5.0毫米钻头组装,在测试主轴上旋转,并使用激光传感器测量跳动值。实际跳动值记录在质检报告中,随发货文件一并提供给您。如果跳动超过0.005毫米,该刀柄将被报废——绝不返修。

适配您的机床主轴或刀具夹持系统

标准柄部为直柄,直径10毫米、长度30毫米,但我们可以加工您需要的任何柄部配置:螺纹柄、锥柄或带紧定螺钉平面的柄部。请将您的主轴图纸或刀柄零件号发送给我们,我们将精确匹配几何尺寸。我们还提供预装您所选尺寸ER11夹头的刀柄,这样您无需单独购买夹头。对于深孔钻削,我们可以在刀柄本体上增加内冷孔。

最小起订量是多少?

无起订量——您可以订购单件用于设备测试,订购10件起可享受数量折扣。

能否定制柄部或夹持范围?

可以,我们可根据您的图纸或样品零件加工定制柄部、加长长度以及最高7.0毫米的特殊夹持范围。

大批量订单如何控制质量?

我们对每批次采用SPC(统计过程控制),每支刀柄均附带三坐标检测报告和跳动证书。

定制ER11夹头刀柄的标准交期是多久?

标准规格48小时内发货;定制柄部或材料需5-7个工作日,加急订单可收取额外费用。

购买前,请查阅我们的数控刀具选型指南,了解这款刀柄如何融入您的整体刀具策略。如需了解刀柄本身的更高精度要求,请参阅我们的数控加工公差指南,了解我们能为您的定制零件保证的精度范围。

这款数控加工ER11弹簧夹头刀柄带钻头为中国制造,专为停机即产生成本的生产环境而设计。每支刀柄均经过检验、测试并附带检测报告发货。我们是一家拥有20年经验的精密制造工厂,我们为自身的产品质量负责。

请将您的图纸或主轴接口详细信息发送给我们,我们将在12小时内提供正式报价。邮箱:sc@bquq.com 或 WhatsApp:+86 13713157787。无起订量,无最低订购要求——只需一支真正精密的刀柄。
