本夹头系列的优势:夹持牢固、零跳动、快速发货

这是我们完整的数控加工自动车床夹头全系列产品——ER8至ER50,以及5C、R8和定制自动车床夹头。每个夹头在鼻端研磨至跳动≤0.005 mm TIR,淬硬至58-62 HRC,表面光洁度达Ra 0.4 µm。标准尺寸15天发货;定制型材20天发货。无最小起订量——订购一件或一千件均可。

为什么ER夹头比钻夹头夹持刀具更稳固

ER夹头沿刀具柄部全长锥面夹持,而非仅三点接触。这使夹紧力均匀分布,消除了卡爪卡盘常见的摆动问题。我们的自动车床夹头开槽精确——ER11及以下开8槽,ER16及以上开12槽——确保夹头同心闭合。结果是:可在20,000 RPM下运行而无振动,与标准卡盘相比,刀具寿命延长高达30%。

材料与热处理:8620钢,整体淬硬,非表面渗碳

我们所有夹头均采用AISI 8620合金钢加工。经过数控车削和铣削后,整体淬硬至58-62 HRC,然后回火以保证尺寸稳定性。表面渗碳夹头磨损快——我们不采用这种工艺。对于耐腐蚀应用,我们提供17-4 PH不锈钢,硬度45-50 HRC。每个夹头在热处理后进行内孔研磨,确保孔径公差达到+0.005/-0.000 mm。这是中国制造的精密加工,但符合ISO 9001标准,而非“差不多就行”的标准。

全系列覆盖:从ER8微型夹头到ER50重型卡盘

我们的系列涵盖您数控车床和铣床所需的所有标准尺寸:

每次发货前检验:气动量仪和光学投影仪

我们不做抽检。本全系列中的每个夹头均逐件检验。首先,使用气动量仪测量孔径,分辨率达0.001 mm。然后将夹头安装在测试夹具中,用千分表在鼻端和距鼻端25 mm处检查跳动。最后,在光学投影仪上验证槽几何形状和锥角(ER系列为8°)。每批订单随附签字的检验报告。如果夹头任何一项检查不合格,即报废处理,不返修。

定制自动车床夹头:我们加工您的型材,而非仅标准尺寸

标准夹头夹持圆形棒料。但您的零件可能是六角形、方形或不规则型材。将您的图纸发送给我们,我们将数控加工定制夹头型材,精确匹配您的零件。我们保持相同公差——≤0.005 mm跳动——以及相同硬度。定制型材交期20天。我们已为瑞士型车床、滑动头机床和多主轴自动车床制造过夹头。直径50 mm以下的型材免收刀具费用。

如何匹配夹头与主轴:您需要的三个参数

下单前,请检查机床上的三项内容:夹头锥角(ER标准为8°)、拉杆或螺母的螺纹尺寸(例如ER16为M12,ER25为M16),以及您将进给的最大棒料直径。如果不确定,我们的工程师将协助您匹配——只需发送主轴图纸或机床型号。这与我们在CNC刀具选择指南中阐述的逻辑相同,我们在其中详细分析了夹头与卡盘的选型决策。关于使用这些夹头加工的零件公差限制,请参阅我们的CNC加工公差指南

为什么直接从东莞工厂采购

我们是BQUQ,一家位于中国东莞、拥有20年历史的工厂。我们在内部完成机加工、冲压和研磨——无贸易公司中间环节。这意味着您获得工厂价格(通常比分销商价格低20-30%)、直接工程支持以及材料证书的完整可追溯性。我们的夹头被全球汽车、航空航天和医疗器械制造商广泛使用。由于我们是工厂,我们可以在无最小订单限制的情况下将任何夹头适配到您的机床。

该夹头系列的最小起订量是多少?

无最小起订量——我们接受单件夹头订单,但每个尺寸订购10件以上时价格略有优惠。

能否为非标准棒料形状制作定制夹头?

可以,发送您的图纸或样品;我们在20天内数控加工定制型材(六角、方形、花键),并保持相同的≤0.005 mm跳动。

如何确保大批量生产中的质量一致性?

我们对每批产品采用SPC(统计过程控制)——硬度测试按5%比例抽检,100%的产品通过气动量仪进行孔径测量。

如果今天下单,实际交期是多少?

标准ER夹头在订单确认后15天内发货;定制型材20天内发货;紧急订单可提供空运快递服务。

发送您的图纸,12小时内获得正式报价

不要再猜测夹头是否匹配。将您的主轴图纸、零件型材或仅机床型号发送给我们。我们将在12个工作小时内回复正式报价——价格、交期和推荐夹头尺寸。将图纸发送至sc@bquq.com或通过WhatsApp联系+86 13713157787。对于标准尺寸,您也可以直接从本全系列中订购——无需图纸,只需提供ER编号和孔径尺寸即可。
