这款夹头为您的自动车床主轴带来的独特优势

这是一款CNC加工的自动车床46型夹头,经过精密研磨和镜面抛光,用于夹持棒料或刀具,总指示跳动(TIR)为0.005 mm。在整个夹持范围内提供一致的夹紧力,这意味着更少的废品和更低的滑动主轴箱刀具磨损。夹头采用淬硬合金钢制造,硬度58–60 HRC,可在高速循环中保持几何精度,标准尺寸从我们东莞工厂发货,交货期7天。

为什么镜面抛光内孔优于标准研磨表面处理以利于排屑

内孔和夹头座经过抛光至Ra 0.2 µm,而不仅仅是研磨。这种镜面效果有两个作用:降低夹头闭合时的摩擦,并防止不锈钢或铝材加工时细碎切屑焊接到表面。在我们的排屑测试中,在相同主轴转速下,抛光内孔清除切屑的速度比仅研磨表面快30%。同时,它还能更好地密封冷却液侵入,保护锥面在数千次循环中保持性能。

我们用于46型主体的材料和热处理工艺

夹头主体采用20CrMnTi渗碳钢,渗碳深度0.8–1.0 mm,然后淬火并回火至58–60 HRC。夹头本身采用65Mn弹簧钢,弹性手指部分热处理至45–48 HRC,鼻端硬化至55 HRC。我们不会使用较软的1045或4140钢制造主体,因为那些材料在6000 RPM的重复夹紧下会变形。每批次在三个点进行硬度测试,而不仅仅是一个角落。

我们如何在研磨和抛光过程中控制跳动

跳动不是事后考虑的问题——它是在研磨阶段就建立的。我们粗磨锥面,然后在180°C下进行4小时去应力处理,最后在配备静压主轴的内圆CNC磨床上精磨。研磨后,我们手工研磨内孔至Ra 0.2 µm,并使用马波斯量仪在三个深度(距鼻端10 mm、20 mm和30 mm)验证TIR。任何TIR超过0.005 mm的夹头将被拒收,而不是返工。

每次发货前的检验:您将在报告中获得的内容

每只夹头都附带书面检验证书,而不是样品批次证书。我们测量并记录:鼻端TIR、主体和夹头的HRC硬度、内孔表面光洁度Ra以及锥面接触面积(我们通过蓝油检查目标达到90%接触)。如果您要求,我们还会提供针对您特定内孔尺寸的跳动测试视频。这是我们精密制造流程的一部分——我们不会为了快速交货而跳过任何步骤。

非标准棒料的定制内孔和槽型选项

如果您的棒料不是标准公制尺寸,我们可以在15天内根据您的图纸加工夹头内孔。我们还可以添加用于六角或方形棒料的纵向槽,或用于带肩零件的阶梯内孔。最小定制内孔为Ø1.0 mm,最大为Ø46.0 mm。请将您的棒料公差发送给我们,我们将推荐夹持间隙——通常为圆棒料公称尺寸的0.02–0.05 mm。

这款夹头的最小起订量是多少?

无最小起订量——我们接受单件测试,您将获得与批量订单相同的检验报告。

您能否根据我的特定主轴定制内孔或锥度?

可以,如果您提供图纸或配合主轴样品,我们可以修改内孔直径、添加六角/方形棒料槽,或调整锥角。

发货前如何验证质量?

每只夹头都经过TIR、硬度、表面光洁度和锥面接触的单独检验,证书随货附上作为标准配置。

如果今天下单,实际交货期是多少?

标准46型夹头7天内发货;定制内孔或槽型版本在图纸批准后15天内发货。

请提供您的主轴和棒料规格以获取正式报价

请将您的主轴鼻端类型、棒料直径和预期转速范围发送给我们。我们将在12小时内回复正式报价,包括运费和公差建议。对于特殊锥度,我们还可以提供适配套筒建议。这是一款中国制造的精密制造产品,我们为任何跳动缺陷提供100%更换保修。

将您的图纸发送至sc@bquq.com,或通过WhatsApp联系我们+86 13713157787。请包含您的目标TIR和材料类型——我们将确认46型是否适合您的机床,或建议替代方案。

为延长自动车床的刀具寿命,请查阅我们的CNC刀具选择指南,以匹配正确的刀柄。如果您正在挑战低于0.01 mm的公差,请阅读我们的CNC加工公差指南,了解0.005 mm TIR对您的工艺的实际意义。
