这套ER夹头卡盘分解件为您带来的价值

这是一套完整的ER夹头卡盘分解零件套件:夹头螺母本体、背紧螺母和精密磨削的锥形座。您将获得鼻端0.005 mm TIR(总指示跳动)、Ra 0.4 µm的表面光洁度,以及夹持表面HRC 58-60的硬度。标准尺寸交期为15天,我们从东莞发货,首次工程样品无起订量。

ER夹头螺母本体如何将旋转力转化为夹持压力

夹头螺母本体是关键的扭矩传递路径。当您拧紧螺母时,内部30度锥面迫使夹头瓣径向向内收缩。我们的螺母本体螺纹按照ISO 6H公差加工,即使在40 N·m扭矩下也能确保顺畅啮合且无卡滞。锥形座经过磨削而非仅车削加工,以确保夹头外径与主轴轴线的同心度在0.003 mm以内。这正是消除刀具振颤并实现切削刃处0.005 mm跳动的关键。

我们用于夹头螺母本体的材料与热处理工艺

我们采用42CrMo4合金钢加工螺母本体,而非廉价的1045钢。CNC车削和铣削后,我们对螺纹和锥面进行渗碳处理,渗碳层深度为0.8 mm,然后淬硬至HRC 58-60。外表面进行发黑处理以提高耐腐蚀性,但锥面和螺纹侧面保持清洁以确保尺寸精度。对于不锈钢或铝制主轴应用,我们可根据要求提供17-4PH版本,硬度为HRC 40-45。每批次均使用洛氏硬度计进行硬度测试,任何低于HRC 57的零件均被拒收。

分解件:包装盒内的配置清单

| 规格 | 数值 | |------|-------| | 产品类型 | ER夹头卡盘分解件(螺母本体+背紧螺母+锥形座) | | 夹头范围 | ER11, ER16, ER20, ER25, ER32, ER40 | | 柄径选项 | 1/8"至1-1/4"(可提供公制等效尺寸) | | 螺纹类型 | 公制细牙(M12x1.5至M40x1.5)或英制(UNF) | | 材料 | 42CrMo4(标准),17-4PH(可选) | | 硬度 | HRC 58-60(表面硬化) | | 锥角 | 每侧30°,磨削至±0.05° | | 跳动(TIR) | 鼻端0.005 mm,4倍直径处0.008 mm | | 表面光洁度 | 锥面Ra 0.4 µm,螺纹Ra 0.8 µm | | 公差 | 螺纹螺距±0.01 mm,外径±0.02 mm | | 交期 | 标准尺寸15天,定制20天 | | 起订量 | 样品无起订量,生产订单10件起 |

每次发货前的检验:跳动与螺纹检测

我们绝不盲目发货。每件夹头螺母本体均经过螺纹环规(6H级)和带千分表的锥度规检测。跳动在测试心轴上使用分辨率为0.001 mm的指示表测量。我们还使用便携式洛氏硬度计检测硬度点,并将数值记录在批次报告中。如果任何零件超过0.005 mm TIR,将被报废处理,绝不会送到您手中。每次发货均附带数字检测报告,包括材质证书和热处理曲线。

该设计为何能与您现有刀具系统兼容

分解式设计让您只需更换磨损的螺母本体或锥形座,无需购买整套卡盘。与整体式卡盘相比,刀具成本可降低约40%。螺母本体带有滚花表面,适用于标准扳手,背紧螺母预钻了平衡螺丝孔,适用于15,000 RPM以上的运行工况。我们将锥度与任何品牌的ER标准夹头匹配——Rego-Fix、Techniks或通用品牌——因为30度锥角是通用标准。

适用于您主轴的定制尺寸与高速选项

如果您使用BT30或HSK主轴,需要更短的螺母本体以减少悬伸量,我们可以将外径加工至0.5 mm壁厚而不损失螺纹强度。对于20,000 RPM以上的高速加工,我们在螺母本体上增加平衡孔,并将组件动态平衡至G2.5@25,000 RPM。只需发送您的主轴图纸或现有卡盘尺寸,我们将在48小时内提供CAD模型。

常见问题解答

这些夹头螺母本体的最小起订量是多少?

样品无起订量——您可以订购一件进行配合和跳动测试,生产订单10件起订。

能否根据我的主轴定制螺纹尺寸或锥角?

可以,我们可以加工任何公制或英制螺纹,并可修改锥角±0.5度,但我们建议标准ER夹头保持30度锥角。

如何确保热处理后跳动保持在0.005 mm?

我们在淬火后进行锥面磨削而非之前,并使用重复精度为0.002 mm的活顶尖来消除渗碳引起的变形。

定制ER夹头卡盘分解套件的交期是多久?

标准尺寸15天内发货;定制螺纹或材料需20天,我们会在采购订单确认时提供物流跟踪号和确定的交货日期。
