这是一款CNC加工的HSK63A弹簧夹头,配备钻头夹持器,专为一项任务而设计:在CNC主轴上牢固夹持钻头,确保钻出精准的孔。其具体优势在于:鼻端实测跳动≤0.003 mm,夹持表面硬度为HRC 58-62,从图纸批准到发货的标准交期为15天。您能获得可重复的孔位和孔径精度,避免损坏刀具寿命的振颤,也无需进行侵蚀利润的返工。

HSK63A锥柄为何比BT刀柄锁紧更牢固

HSK63A刀柄为中空结构,采用双面接触系统——锥面和法兰同时接触主轴端面。我们的夹头由整块20CrMnTi合金钢坯料加工而成。锥面以1:10的角度磨削,公差等级为AT3,这意味着接触面积超过理论表面的90%。即使在12,000 RPM转速下承受重型钻孔负载,也能防止刀柄被拉出。您会在进给速率上感受到差异:典型客户使用10 mm钻头以0.15 mm/转的进给量运行,无任何振动。

ER弹簧夹头夹持精度:为何选择ER32而非整体式夹头

我们在此HSK63A刀柄中使用ER32弹簧夹头,因为每个夹头提供1 mm的夹持范围,因此您可以在不更换夹头本体的情况下,从6 mm钻头切换到7 mm钻头。夹头座以8°内角磨削,表面粗糙度Ra 0.4。螺母经过淬硬处理至HRC 48-52,并采用螺纹磨削以防止磨损。当您将螺母拧紧至我们印在主体上的规格(例如ER32为80 Nm)时,夹头均匀压缩,以15 kN的径向夹紧力夹持钻头柄部。

我们使用的材料与热处理工艺

主体材料为20CrMnTi,经渗碳处理至硬化层深度0.8-1.2 mm,然后淬硬至HRC 58-62。芯部保持韧性,硬度为HRC 35-40,以吸收断续切削产生的冲击。钻头座经过精密镗削,然后珩磨至H7直径公差。我们对内孔表面进行氮化处理,达到700 HV的显微硬度,提供干式润滑性,防止钻头柄部产生切屑焊接。锥面不施加任何涂层——采用磨削而非电镀,以保持接触几何精度。

每次发货前的检测

每只夹头均通过三坐标测量机(蔡司Contura)检测锥角与同轴度。跳动在夹头鼻端使用分辨率为0.0005 mm的千分表测量,数值记录在随货附带的检测报告中。我们还使用标准HSK63A主轴进行蓝油测试检查锥面接触率——接触率低于85%的产品一律拒收。钻头夹持器使用标准10 mm HSS钻头进行测试,验证夹头能顺利释放钻头,无卡滞现象。

高速钻孔动平衡

我们对每只HSK63A夹头在15,000 RPM下进行G2.5动平衡。这意味着残余不平衡量小于每公斤刀柄重量2.5 g·mm。对于典型的1.2 kg刀柄,残余不平衡量为3 g·mm。如果您在12,000 RPM以上运行钻头,这能防止导致孔径超差的谐波振动。对于超精密加工,我们提供可选的平衡报告,显示精确的校正重量和角度——这会增加2天交期,但不额外收费。

如何按您的特定钻头直径下单

我们将钻头座加工至您的精确柄径——标准为H7公差,但如果您要求,我们可达到H6。请将您的钻头柄径(例如10.00 mm)、夹头总长(标准为100 mm,我们可做75-150 mm)以及是否需要内冷孔(标准为5 mm中心孔)发送给我们。我们将在24小时内确认图纸。对于非标准柄径(例如9.8 mm),我们生产定制磨削至该尺寸的夹头袋——数量超过10件时无需额外刀具费用。

是否有最低起订量(MOQ)?

无起订量——我们接受单件用于评估,数量达到20件及以上时,单件价格约降低20%。

能否为特定钻头柄定制夹头?

可以,我们将夹头座或钻头孔加工至您的精确直径(H6或H7公差),并可按要求增加内冷孔或定制法兰结构。

如何确保发货后跳动保持在0.003 mm?

我们在最终清洁后对每件产品进行人工检测,并包装在泡沫内衬箱中;检测报告包含包装前测量的跳动值,我们保证在正常搬运条件下该数值有效。

定制HSK63A弹簧夹头的交期是多久?

单件标准交期15天,数量超过50件为20天,我们提供7天加急选项,需加收15%费用。

如需在12小时内获得确定报价,请发送邮件至sc@bquq.com或通过WhatsApp联系+86 13713157787。发送您的图纸或仅提供钻头直径和主轴型号——我们将回复价格和3D STEP文件。如果您正在将此产品与其他刀柄进行比较,请查看我们的CNC刀具选择指南,获取ER、液压和热缩刀柄的全面对比。要了解我们的公差承诺,请阅读我们的CNC加工公差指南。这是精密制造,中国制造,无起订量——我们通过DHL或FedEx在完工后3天内全球发货。
