这是一款CNC加工自动车床20型方孔弹簧夹头,专为夹持方形或六角棒料设计,确保零变形。我们保证跳动精度(TIR)为0.005 mm,硬度为HRC 58–60,东莞工厂生产交期15天。该夹头专为大批量瑞士型及自动车床加工而设计,可夹持3 mm至20 mm方棒,且不会损伤工件表面。

为什么方孔夹头在自动车床加工中优于圆爪

方棒在圆爪中会打滑,这会浪费您的循环时间并产生废品。此夹头的方孔与工件几何形状完全匹配,将夹紧力分布在四个平面上,而非四个点上。与同材料的圆孔夹头相比,扭矩传递能力提升30%。弹簧钢本体在受控范围内弹性变形,因此无需液压辅助即可在2秒内完成零件装卸。

我们使用的材料牌号及热处理工艺顺序

根据您的批量大小,我们选用65Mn弹簧钢或SK5高碳钢。对于不锈钢或淬硬工件,我们推荐采用表面渗氮处理的SK5版本。热处理工艺为:830°C淬火、油冷、380°C回火2小时,然后-80°C深冷处理以消除应力。最终硬度为HRC 58–60,每个夹头在三个点使用洛氏C标尺测量。内孔表面粗糙度为Ra 0.2 µm,可防止软铝或黄铜工件出现咬合现象。

跳动控制:从毛坯管料到最终磨削

跳动控制绝非事后考虑。我们在CNC外圆磨床上以一次装夹同时磨削外圆和内孔,将20型锥度控制在0.003 mm以内。然后,我们在距夹头端部20 mm处的精密心轴上测试每个夹头。最大允许TIR为0.005 mm,该数值印在随订单附带的检验卡上。任何超过0.005 mm的产品均被拒收——绝无例外,也绝不通过放宽公差来返工。

20型自动车床的尺寸范围及槽型几何结构

此夹头适配标准20型自动车床主轴(如Citizen、Tsugami、Star、Hanwha)。我们常备的方孔尺寸:3、4、5、6、8、10、12、14、16、18、20 mm。槽宽为1.2 mm,底部带有60°卸荷角以防止应力断裂。夹头头部外径为20.00 mm(+0.000 / -0.005 mm),锥角为16°(包含角)。每个夹头重约85克,因此单件运输成本较低。

每次发货前的检验:绝非纸上盖章

每个夹头在包装前均经过四步检查。第一步:使用三丰HR-530硬度计进行硬度测试。第二步:使用三点内径千分尺检查内孔尺寸。 第三步:使用带校准测试棒的同轴度指示器进行跳动测试。第四步:在10倍放大镜下进行目视检查,查看是否有烧伤或微裂纹。我们保留数字记录5年。若您在30天内发现任何缺陷,我们将免费更换并承担运费。

如何根据您的工件材料匹配此夹头

对于软材料(铝、黄铜、铜),请使用标准槽型的65Mn版本。对于硬度超过HRC 40的淬硬钢,请订购带渗氮表面的SK5版本——其耐磨性提高3倍。对于六角棒料,订购20件以上时,我们可以免费将内孔修改为六角形状,无需额外刀具费用。对于带尖角的方棒,请在图样上注明圆角半径;我们可将圆角半径公差控制在0.1 mm以内。

从东莞到您手中的包装与运输

每个夹头均单独包裹防锈纸,置于泡沫衬垫中,并附带QC报告装箱。5 kg以下的订单,我们通过DHL或FedEx发货,通常3–5天可达美国或欧盟。较大订单可选择海运,采用木托盘包装。每个箱子均标注零件号、批次代码和您的采购订单号。每箱绝不混批——确保可追溯性。

最小起订量是多少?

无起订量——订购1件用于测试,或1000件用于生产,我们均以相同的质量标准发货。

能否定制内孔尺寸或材料?

可以,我们可生产3 mm至20 mm的方形、六角形或异形内孔,并可根据您的工件硬度改用SK5或9SiCr合金钢。

单件订单如何控制质量?

即使是单件产品,也会经过相同的四步检验(硬度、内孔尺寸、跳动、目视检查),并附有签名的QC卡发货。

定制方孔夹头的交期是多久?

标准尺寸15天内发货;定制形状或材料需20–25天,如需加急至10天,需加收15%的加急费。

需要明确报价?请发送您的图样,或仅提供方棒尺寸和材料规格。我们将在12小时内回复,提供固定价格和交货日期。邮箱:sc@bquq.com。WhatsApp:+86 13713157787。如需了解更多刀具选择信息,请阅读我们的CNC切削刀具选择指南。如果您正在检查下一个项目的公差限制,请参阅我们的CNC加工公差指南。此夹头为精密制造产品,中国制造,无起订量——现可立即发货。
