25-700系列涵盖范围及其重要性

这是从25号到700号的完整自动车床夹头系列,覆盖您在瑞士型和CNC自动车床上会遇到的所有标准主轴孔径。我们采用淬硬合金钢加工这些夹头,夹持直径公差研磨至±0.005mm,最大跳动量为0.005mm TIR。这意味着您的棒料在第一次走刀时就能精准对中——无需返工、无废品、无振纹。该系列任何尺寸的标准交期为10个工作日,我们常备25、42、65和100号尺寸的毛坯库存。

该系列专为连续生产而设计。夹持表面硬度保持在HRC 58至62之间,我们对内孔进行氮化处理,以减少加工303不锈钢或17-4PH等磨蚀性材料时的磨损。在整个范围内您都能获得一致的夹紧力,这直接转化为更长的刀具寿命和更好的车削零件表面光洁度。对于精密制造作业而言,这不是奢侈品——而是能否稳定保持±0.01mm公差与整班追着公差跑的区别。

我们如何在25至700范围内消除跳动

跳动是精度的天敌。我们在磨削阶段解决这一问题,而非装配阶段。此CNC加工自动车床全系列25至700夹头集合中的每一只夹头均在单次装夹中完成磨削,使用固定式无心磨床配合金刚石修整器,每加工50件即重新修整一次。结果:在测量最终零件之前,夹持直径与锥度座已同心至0.003mm以内。

槽口在热处理后采用线切割加工,而非热处理前。这防止了淬火过程中的变形。25-200号尺寸切6条槽,300-700号尺寸切8条槽,使夹头在无应力集中的情况下均匀径向收缩。当夹头闭合于棒料时,夹紧力沿圆周均匀分布,不会产生导致零件失圆的"三瓣"效应。我们每批次均在Talyrond圆度仪上验证这一点,检测报告随货附入箱内。

能够承受高速加工的材质与热处理工艺

我们采用8620渗碳钢制造本体,6150弹簧钢制造夹爪。本体渗碳层深度0.8mm,淬硬至HRC 60-62。夹爪经淬火回火至HRC 52-56,使其具备数百万次循环而不开裂所需的弹性回复能力。这种组合并非随意选择——它与欧洲高端主轴刀具所用冶金工艺相同,但我们在东莞以更低成本制造。

对于夹持表面,我们在300号以上尺寸施加氮化钛涂层。该涂层将摩擦系数降至0.4,可防止夹持预磨棒料时产生咬合。如果在高进给机床上使用无涂层夹头,一周内就会在棒料上看到粘附痕迹。使用我们的TiN涂层后,这些痕迹消失。涂层厚度为2-3微米,我们每10件用Fischer测厚仪检测一次。

每次发货前的检测——我们测量什么及为何重要

没有完整的尺寸检测报告,我们不会发出任何一只夹头。每只夹头均测量内孔直径、锥度角、跳动量和硬度。锥度角使用正弦规和量块检测,而非量角器。跳动量在配备0.001mm千分表的精密主轴上测量,最大TIR值记录在报告中。硬度使用洛氏硬度计分别在本体和夹爪尖端测试。

报告包含批次号、操作人员和检验员签名。任何一只夹头都可以追溯到热处理炉和砂轮。我们还使用5倍放大镜进行100%外观检查,查看边缘崩口、毛刺或磨削烧伤。如果发现烧伤痕迹,该夹头直接报废——不返工。这就是此CNC加工自动车床全系列25至700夹头集合的标准,也是为什么我们的汽车和医疗器械制造客户无需重新发送图纸即可重复下单。

无需图纸即可选择正确的夹头尺寸

如果您不确定哪种尺寸适合您的主轴,请将主轴鼻端锥度角和最大棒料直径发送给我们。我们将与系列对照表进行交叉比对,在一小时内告知您确切的产品编号。25系列适配1/8"至1"棒料,42系列适配1/4"至1-5/8",700系列适配最大2-3/4"。我们还为每种尺寸提供公制等效型号,您无需进行任何换算。

对于定制内孔直径,我们按照您的确切棒料尺寸加工夹头,而不仅限于标准增量。如果您使用12.7mm棒料但标准夹头为12.5mm,我们将扩孔至12.7mm,公差为+0.005/-0.000。定制内孔的交期仍为10个工作日,价格仅比标准尺寸上浮15%。这是我们精密制造服务的一部分——我们不会强迫您购买不适合您工艺的标准尺寸。

全球运输的包装与文件

每只夹头均单独用VCI防锈纸包裹,防止海运过程中腐蚀。纸张含油但不会在钢材上留下残留物。25-100号尺寸每盒装10件,300-700号尺寸每盒装5件。外箱为双层瓦楞纸板配泡沫内衬,确保夹头在运输中不会相互碰撞。过去五年中我们已发货超过12,000只夹头,无一例损坏索赔。

文件包括材质证书、尺寸检测报告和热处理证书。如果您需要PPAP三级提交文件,我们也可以生成——需额外2天时间,每个零件编号收费$50。对于欧洲或北美客户,我们可提供EU RoHS声明和REACH合规声明。我们不是贸易公司,我们就是工厂,因此所有文件均来自我们自己的质量体系。

成本构成及我们如何保持价格竞争力

价格取决于尺寸和数量,以下是标准系列的参考价格:25号在100件时每件$8.50,42号每件$12.80,100号每件$24.50,700号每件$68.00。这些价格包含TiN涂层和完整检测报告。如果您订购全系列(25至700号各一件),我们给予20%折扣,并将所有产品装入一个木箱发货以提供保护。

我们保持低成本是因为我们在内部控制整个流程——热处理、磨削、线切割和涂层。我们不外包任何工序,因此没有中间商加价。这是直接与工厂合作的中国制造的真实优势。无起订量意味着您可以订购5件试运行或500件用于生产线。我们的最小订单量为零。

何时使用此夹头而非液压卡盘

当您需要在标准棒料尺寸上实现快速换型和重复精度时,应使用这些夹头。液压卡盘提供更好的减振性能,但更换需要20分钟。我们的夹头使用紧定螺钉或快换螺母仅需2分钟即可更换。对于一天内运行10种不同棒料尺寸的加工车间,节省的时间比液压系统略微的减振优势更有价值。

如果您加工直径低于3mm的长而细的零件,液压卡盘更合适,因为它能更均匀地支撑棒料。但对于6mm至70mm的任何尺寸,我们的夹头是正确的选择。我们还销售配套的夹头卡盘,锥度匹配,因此您无需混用品牌。如果您不确定您的应用需求,请将零件和主轴的图纸发送给我们,我们将推荐正确的配置。我们的工程师会在12小时内回复。

该夹头系列的最小起订量是多少?

无起订量——您可以订购一只夹头进行测试,我们当周发货。

您能否定制内孔直径以匹配我的确切棒料尺寸?

可以,我们可在25至700的任何尺寸上加工定制内孔,公差±0.005mm,价格调整15%,交期同样为10天。

你们如何保证每件产品的跳动和硬度?

每只夹头均使用Talyrond圆度仪进行100%跳动检测,使用洛氏硬度计进行硬度检测,报告随货附入您的发货中。

全系列集合的标准交期是多少?

标准尺寸10个工作日内发货,定制内孔12天,全系列木箱装15天。
