这是一款CAT40 ER25弹簧夹头刀柄,由AISI 4140实心钢在我们的东莞工厂CNC加工而成。核心优势很简单:您获得夹头鼻端可重复跳动≤0.005毫米,硬度HRC 58-60,标准交货期15天。如果您厌倦了多次装夹后漂移的刀柄,这款产品能保持几何精度,因为我们在加工后进行热处理,而不是之前。

ER弹簧夹头如何无跳动夹持刀具

ER25弹簧夹头系统使用锥形锥体,均匀压缩在刀具柄部周围。我们的CAT40锥度磨削至AT3等级,这意味着与主轴的接触面积超过90%——而不是廉价刀柄上常见的70%。然后我们在与CAT40锥度相同的装夹中磨削夹头座,因此夹头鼻端的中心线与主轴轴线精确对齐。这就是为什么即使在500多次换刀后,我们的跳动仍保持在5微米以下。我们用6毫米测试棒测试每个刀柄,而不是精密磨削的标准棒,因此您看到的数字就是生产中得到的数字。

我们使用的材料和热处理

我们从AISI 4140铬钼钢开始,而不是易切削的12L14。毛坯经过车削和铣削,然后使用真空炉和氮气淬火硬化至HRC 58-60。硬化后,我们进行两次回火以消除内应力——这防止CAT40锥度在高速主轴夹紧时变形。ER25螺纹在热处理后切削,然后整个刀柄进行黑色氧化处理,厚度10微米。黑色氧化不是装饰性的;它防止冷却液引起的生锈,并提供哑光表面,减少机床灯光下的眩光。对于不锈钢冷却液管路或大量使用冷却液的用户,我们可以提供镀镍选项,但标准库存为黑色氧化。

每次发货前的检验

我们不会发货未经单独检查的刀柄。每个CAT40 ER25弹簧夹头刀柄经过四个检验步骤:(1)使用50%蓝油测试对标准规进行锥度接触检查,(2)使用6毫米测试棒在距鼻端10毫米处测量跳动,(3)使用150千克载荷的洛氏C硬度计在柄部进行硬度测试,(4)螺纹通止规检查。所有结果记录在PDF报告中,随货发送。如果任何值超出公差,零件将被报废,而不是返工——返工锥度会破坏其同心度。这是中国制造的精密制造,但检验标准与您对德国或日本供应商的期望相同。

高速加工的平衡选项

如果您的主轴转速超过10,000 RPM,您需要平衡刀柄。标准刀柄在15,000 RPM下平衡至G6.3,适用于大多数钻孔和铣削。对于20,000 RPM或更高的精加工操作,我们提供G2.5平衡作为付费选项。平衡过程从法兰去除材料,而不是锥度,因此永远不会影响配合。告诉我们您的最大转速和刀具组件重量,我们将为您计算正确的等级。不平衡的刀柄会导致工件上出现振纹并磨损主轴轴承——这不是省钱的地方。

此刀柄如何与您现有刀具配合

ER25弹簧夹头是世界标准,因此您可以使用任何品牌的ER25弹簧夹头——从Rego-Fix到Techniks再到通用中国夹头。我们刀柄上的夹头螺母使用标准34毫米六角,因此您现有的扳手可用。刀柄体有18毫米通孔,如果添加冷却液适配器,足以用于内冷应用。如果您使用带主轴内冷的钻孔操作,我们的标准刀柄没有冷却液孔——您需要在图纸阶段指定冷却液选项。对于铣削,实心体比模块化系统更能吸收振动,因此根据我们的客户测试,与相同跳动的热缩刀柄相比,表面光洁度提高至少20%。

出口包装和运输

每个刀柄单独用VCI(气相防锈)纸包裹,然后放入刚性纸箱内的定制泡沫嵌件中。纸箱上标有零件号、批号和检验日期。对于5千克以下的订单,我们通过DHL或FedEx运输并提供跟踪——运送到美国或欧洲需3-5个工作日。对于较大订单,我们使用符合ISPM-15标准的木箱海运。我们已运往30多个国家,从未在运输中损坏过刀柄,因为泡沫嵌件按刀柄精确形状切割。如果您订购带测试棒,我们将测试棒单独包装在PVC管中,防止刮伤锥度。

最小起订量(MOQ)是多少?

无最小起订量——您可以订购单件进行原型测试,单价与50件批量相同。

您能定制长度或添加冷却液孔吗?

是的,我们可以修改总长度、添加内冷孔或更改平衡等级,但任何修改都需要您在开始加工前批准图纸。

您如何保证单件订单的质量?

每个刀柄,无论数量多少,都经过相同的四步检验,并收到包含实际测量跳动和硬度值的单独测试报告。

如果急需,实际交货期是多少?

标准交货期为15天,但对于最多10件的加急订单,我们可以在7天内交货,需加收单价20%的加急费。

下单前,请查看我们的CNC刀具选择指南,确认ER25是适合您主轴的弹簧夹头系统,并查阅CNC加工公差指南,了解我们的0.005毫米跳动如何满足您的应用要求。
