这款ER20夹头刀柄为您的主轴带来的优势

这是一款数控加工的ER20弹簧夹头刀柄,专为夹持硬质合金立铣刀设计,保证跳动量0.005毫米TIR(在距鼻端3倍直径处测试)。刀柄本体淬硬至58 HRC,锥面和内孔经过磨削加工,从我们东莞工厂发货,交货期15天。您可获得用于精加工工序的重复性刀具夹持,而不仅限于粗加工。

ER20锥度如何无弹性地锁定刀具

ER20夹头刀柄采用8°锥角。拧紧螺母时,夹头径向压缩,而非轴向。这种径向夹紧力在20毫米全长夹持范围内均匀作用于硬质合金立铣刀刀柄。无紧定螺钉、无侧向压力、在重切屑载荷下刀具不会推出。结果是刚性连接,在12,000 RPM转速下刀具偏摆低于0.01毫米。

我们用于刀柄本体的材料与热处理工艺

我们采用AISI 4140合金钢加工刀柄本体,而非廉价的45#碳钢。经过数控车削和铣削后,整体淬硬至58–60 HRC,然后回火消除应力。锥面在容克磨床上磨削,表面粗糙度Ra 0.4 μm。夹头槽和螺纹采用线切割加工,避免产生可能导致跳动漂移的毛刺。

为何我们使用硬质合金立铣刀进行匹配测试

我们发货的每一支ER20夹头刀柄在包装前均与6毫米硬质合金立铣刀(两刃、AlTiN涂层)进行试装。我们在刀柄处和切削刃处测量跳动。若读数超过0.005毫米,则予以剔除。这不是随机抽检,而是每件产品100%全检,跳动检测报告随箱附上。

每次发货前的检测——我们测量什么

我们的质检室使用蔡司三坐标测量机检测锥角(8° ± 5′),马波斯量规检测内孔直径,TIR指示表检测跳动。我们还使用通止规检测螺纹螺距。每支夹头刀柄均激光蚀刻序列号。通过该编号可追溯热处理批次和磨削操作员。没有这些文件,我们不会发货。

规格与订购——无起订量,可混合批次

我们常备ER20夹头刀柄,柄径规格为16毫米、19.05毫米(3/4″)、20毫米和25.4毫米(1″)。提供直柄、CAT40、BT30和BT40规格。您可订购1件用于样件试制,也可订购500件用于批量生产。无最小起订量。同一订单可混合不同规格——单价保持不变。

最高转速20,000 RPM(可选G2.5动平衡)
交货期标准规格15天
起订量无最低要求——可订购1件或更多

如何避免常见夹头刀柄故障

大多数跳动问题源于锥面脏污或螺母过紧。每次换刀前用溶剂清洁刀柄内孔和夹头。使用扭矩扳手——ER20标准扭矩为60–70 Nm,而非100 Nm。若发现夹头槽有磨损痕迹,请更换夹头,而非刀柄。按照此方法操作,我们的刀柄本体设计寿命为10,000次以上夹持循环。

这款ER20夹头刀柄的最小起订量是多少?

无起订量——您可订购单件用于样件试制,价格与批量订购相同。

能否定制柄长或动平衡等级?

可以,我们提供定制柄长、内冷孔和用于高速主轴的G2.5动平衡,工程图纸出图周期为3天。

小批量订单如何控制质量?

每支夹头刀柄,无论订单大小,均经过相同的100%全检,使用三坐标测量机和TIR指示表检测,发货前我们会将检测报告通过电子邮件发送给您。

如果订购100件,实际交货期是多少?

100支标准ER20夹头刀柄(同规格),图纸确认后交货期为12天;混合规格则为15天。

中国精密制造为何对此零件至关重要

我们位于东莞的工厂自2004年起一直生产数控刀柄。我们自有30台数控车床和5台磨床,因此可控制整个流程——车削、淬火、磨削和检测。您不是从贸易商处购买。这是一家精密制造企业,中国制造,具备与德国或日本工厂相同的质量控制纪律,但成本更低。下单前,请阅读我们的数控刀具选型指南,以匹配您的主轴。并查看我们的数控加工公差指南,了解0.005毫米对您的应用意味着什么。

索取正式报价,12小时内获得图纸审核

请将您的主轴型号、柄径和夹头范围发送给我们。我们的工程师将确认确切的ER20夹头刀柄配置,并在12小时内通过电子邮件向您发送附有技术图纸的正式报价。我们接受样件订单和批量生产。无起订量,无隐藏刀具成本。将您的图纸发送至sc@bquq.com,或通过WhatsApp联系我们:+86 13713157787。数控加工ER20弹簧夹头刀柄配硬质合金立铣刀CNC铣削已为您的 spindle 准备就绪。
