这款2J夹头卡盘的独特之处

这是一款用于车床的CNC加工2J夹头卡盘。它以0.003 mm总指示跳动(TIR)夹持您的棒料或刀具柄部。这不是营销数字。这是我们在东莞工厂每件产品出厂前实测的结果。夹持表面硬度为58–60 HRC。表面光洁度为Ra 0.4 µm。标准尺寸的交货期为7–10天。定制内孔需增加3天。无最小起订量。一件或一千件——单价相同。

2J轮廓如何消除振颤和滑移

2J夹头采用20度锥形座。与依赖薄狭缝的ER夹头不同,2J设计使用全长槽和硬化钢体。这提供了0.02 mm的径向弹性。足以吸收棒料直径变化达±0.05 mm而不损失夹持力。在40 N·m扭矩下,鼻端夹持力为12 kN。您可获得用于二次加工的重复夹持。无喇叭口变形。无刀具拉出。这就是为什么这款夹头卡盘是瑞士型车床和排刀式车床的标准配置。

我们使用的材料和热处理工艺

我们从AISI 8620合金钢开始。这不是现成库存。我们从中国认证钢厂采购,附带材质证明。CNC加工成2J轮廓后,我们在920°C下对夹头进行渗碳处理4小时。渗碳层深度为0.8–1.2 mm。然后淬火回火至58–60 HRC。随后在坐标磨床上磨削内孔,以实现0.003 mm TIR。锥面最后磨削,与内孔在同一装夹中完成。这是保证锥面与夹持面同心度的唯一方法。如果您指定贯通冷却液版本,我们在热处理前增加一个1.5 mm横孔。硬化后不进行二次钻孔。

每次发货前的检验

每件2J夹头都附带完整检验报告。我们不抽样。我们100%检验所有产品。报告包括:使用内径千分尺测量内孔直径至0.001 mm精度,使用0.0005 mm指示表在精密主轴上测量TIR,使用洛氏硬度计检查硬度,以及使用轮廓仪测量表面粗糙度。报告由我们的质检工程师签署并随货附送。如果您要求,我们还会提供跳动测试视频。我们已坚持此做法20年。即使小订单也不会省略。

为非标工件定制2J夹头

您的零件并不总是圆形的。我们加工定制内孔轮廓:六角、方形或阶梯形。2J本体保持不变。我们只需更改内孔几何形状。对于六角棒料,我们磨削60度内部让位以防止角部应力。对于阶梯零件,我们增加后导向孔以轴向定位工件。定制内孔的公差为±0.005 mm。我们需要您的DXF或STEP格式图纸。如果您有样品零件,我们可以在此测量并匹配轮廓。典型定制内孔交货期为10–12天。20 mm以下内孔不收取刀具费用。

何时使用2J夹头与ER夹头

当您需要二次加工的死长度精度时,请使用2J夹头。ER夹头在拧紧时会将刀具向后拉。2J夹头不会轴向移动。这就是为什么它能将长度公差保持在±0.01 mm。对于钻孔或铣削等轴向移动无关紧要的场合,请使用ER。如果您正在切削螺纹或切槽,2J是正确的选择。有关刀具与切削匹配的更多信息,请参阅我们的CNC刀具选择指南。如需深入了解实际可行的公差,请阅读我们的CNC加工公差指南

这款2J夹头卡盘的最小起订量是多少?

无最小起订量。您可以订购单个夹头用于打样,或订购一千件用于生产——单价保持不变。

您能为我的非标棒料定制内孔吗?

可以,我们加工定制内孔轮廓(六角、方形、阶梯形),公差为±0.005 mm;发送您的DXF或STEP文件,我们将在12小时内报价。

您如何确保0.003 mm跳动的一致性?

我们在同一装夹中磨削锥面和内孔,然后用0.0005 mm指示表对每件产品进行100%检验,并发送签署报告给您。

标准2J夹头订单的交货期是多久?

标准尺寸在7–10天内发货;定制内孔增加3天,我们通过DHL或FedEx全球发货。

12小时内获取确定报价

发送您的图纸或仅发送内孔尺寸和柄部类型。我们将在12小时内回复确定价格和交货期——无猜测,无隐藏刀具费用。这是中国制造的精密加工,拥有20年CNC加工经验。将您的图纸发送至sc@bquq.com或通过WhatsApp联系我们:+86 13713157787。我们每周7天在线。
