此夹头卡盘的功能及其重要性

这是一款数控加工自动车床46型圆孔弹簧夹头卡盘,专为圆棒料的大批量车削加工而设计。其夹持孔径范围为3 mm至46 mm,总指示跳动(TIR)为0.005 mm,这意味着您的成品零件无需二次磨削即可保持同心度。我们将夹持表面硬化至58–60 HRC,使其在100,000次以上循环中耐磨耐用。标准尺寸的典型交期为15天,从我们的东莞工厂发货,无起订量要求。

46型圆孔夹持几何结构如何减少跳动

46型名称指DIN 6343标准夹头锥度,包含角为16度。我们的圆孔在热处理后一次性装夹磨削完成,而非热处理前——这是保持0.005 mm TIR的关键。弹簧槽采用线切割加工,切缝宽度为0.3 mm,确保六个槽均匀径向收缩。与使用螺母压缩的ER夹头不同,此弹簧夹头卡盘采用拉杆后拉式动作,自动定心棒料。您可获得40–80 N·m的可重复夹持力,且不会损伤软铝或黄铜棒料表面。

我们使用的材料及热处理工艺,确保60 HRC长寿命

我们采用42CrMo4(AISI 4140)钢材,预硬化至28–32 HRC以便加工。经过数控车削和铣削后,进行真空淬火至58–60 HRC,然后在-80°C下深冷处理2小时,以转化残余奥氏体。这确保了稳定的微观组织,使夹头在高速主轴运转时不会变形。内孔和锥度采用CBN砂轮精磨,夹持区域表面粗糙度达到Ra 0.4 µm。对于腐蚀性环境,我们提供可选化学镀镍层,厚度为8–12 µm——但标准交付为普通磨削钢表面。

每次发货前的检验:跳动和硬度检查

每件夹头卡盘均进行100%全检,而非批次抽检。我们检查:(1) 使用测试棒插入后,用0.001 mm千分表检测鼻端TIR;(2) 使用正弦规和量块检测锥度角;(3) 使用洛氏硬度计检测夹持表面硬度;(4) 使用工具显微镜检测槽宽和槽深。您将收到附有序列号和实际测量值的打印检验报告。如果任何夹头超过0.005 mm TIR,将被报废处理,绝不会交付给您。这就是我们退货率低于0.3%的原因。

特殊应用定制孔径和槽型

标准孔径磨削至H7公差,但我们可制作3 mm至46 mm范围内任意孔径,以0.1 mm为增量。对于薄壁管材,我们提供12槽版本替代标准6槽,可更均匀分布夹持力并防止塌陷。对于方形或六角棒料,我们可线切割匹配孔径——只需发送您的截面图纸。我们还可根据铜或PTFE等较软材料调整槽深,如您要求,可将夹持压力降低最多30%。所有定制加工仍在中国东莞工厂完成,30 mm以下孔径同样享受15天交期。

与常见自动车床主轴的兼容性

此夹头卡盘适配大多数46型主轴鼻端,包括Citizen、Star、Tsugami和Hanwha走心式车床,以及Tornos和Esco的固定主轴箱自动车床。标准后部螺纹为M20 x 1.5,但可根据要求加工M18、M22或3/4-16 UNF。总长度为68 mm,可适配大多数导套而无需修改。如果您不确定主轴鼻端规格,请测量锥度角和拉杆螺纹螺距——或发送当前夹头的照片,我们将在一个工作日内确认兼容性。

是否接受单件订单?

是的,我们无起订量——您可以订购单个夹头卡盘用于测试,我们将随附完整检验文件发货。

能否将孔径定制为我的精确棒料直径?

可以,我们以0.1 mm增量磨削3 mm至46 mm范围内的孔径,如果您发送图纸,我们还可切割方形、六角或花键轮廓。

每批次如何确保质量?

我们对每件产品进行100%尺寸检验,包括TIR、硬度和锥度角,并随每次发货附上签署的检验报告。

定制尺寸的典型交期是多久?

标准孔径15天发货;定制轮廓或非标准槽型需20–25天,具体取决于复杂程度。

12小时内获取正式报价——发送您的图纸

我们会在12小时内回复所有询盘,提供正式的分项报价,包括价格、交期和运输选项。请发送邮件至sc@bquq.com或通过WhatsApp联系+86 13713157787。附上您的2D图纸或3D STEP文件,我们将在报价前确认孔径、锥度和螺纹配置。如果您仍在为车床选择刀具,请参阅我们的数控刀具选择指南,以匹配适合的刀片和刀柄。如需了解更多关于我们如何保持0.005 mm TIR的信息,请阅读我们的数控加工公差指南。这就是精密制造,精益求精——中国制造,无起订量,12小时响应。
