这是一款数控加工的自动车床15型六角孔弹簧夹头,专为自动车床和CNC车削中心夹持六角棒料而设计。其跳动精度达0.005 mm TIR,硬度为HRC 58-60,表面光洁度Ra 0.4 µm——全部由我们东莞工厂生产,标准交货期为15天。

六角孔夹头如何无变形锁定六角棒料

内孔几何形状经过精密拉削加工,以匹配15型六角尺寸(例如对边距4 mm、6 mm、8 mm、10 mm)。与会压碎六角边角的圆形夹头不同,该设计在平面上施加均匀的径向力。在5,000 RPM转速下无滑动,成品零件上无压痕。每个夹头都开有0.3 mm的释放槽,每种尺寸的夹持范围为0.1 mm。

我们使用的材料牌号及热处理工艺

我们选用65Mn弹簧钢或9SiCr合金工具钢——两者均因其在高循环夹持中的抗疲劳性能而被选中。热处理采用两步工艺:860°C淬火,然后400°C回火90分钟。最终硬度介于HRC 58-60之间,硬化层深度为1.2 mm。这确保您获得200,000次以上的夹持循环而不损失回弹力。

内孔和柄部的跳动控制——不仅限于尖端

大多数夹头故障源于柄部不对中,而非内孔问题。我们在一次装夹中同时磨削15型锥度(30°包含角)和内孔。结果:孔口处跳动0.005 mm TIR,20 mm深度处跳动0.008 mm TIR。我们还在法兰上激光雕刻尺寸和批次号,以便追溯磨削日期。

每次发货前全检——而非仅抽检

每个夹头均通过3点检查:内孔量规检测六角对边尺寸(±0.01 mm)、CMM扫描锥角(±0.5°),以及在测试心轴上进行动态跳动测试。我们随附带有批次号的签字检验报告。如需完整材料证书(EN 10204 3.1),我们免费提供。

为何我们东莞工厂能保持比标准JIS更严格的公差

标准JIS B 6151夹头允许0.01 mm跳动。我们磨削至0.005 mm,因为我们使用配备在线测量的Studer S33外圆磨床。操作员每加工50件调整一次砂轮磨损,而非每班一次。这就是中国制造的精密制造,成本合理——比日本同类产品低约20%。

长途海运的包装与防锈保护

每个夹头单独用VCI(气相防锈)纸包裹,然后放入带泡沫内衬的塑料盒中。订单超过50件时,我们使用带硅胶干燥剂的木箱。即使集装箱在港口滞留6周,也能防止生锈。外箱上标注零件号、尺寸和热处理批次,便于仓库分拣。

定制六角尺寸的最小起订量是多少?

无最小起订量——我们可以为您的试制批次制作单个定制夹头,但非标六角尺寸的工装费用为$50。

能否修改内孔深度或锥角?

可以,我们可以更改内孔深度、锥角(从30°到45°),或增加冷却液孔,但这些改动可能会增加3-5天的交货期。

如何确保500件批次的品质?

我们每20件对内孔尺寸进行一次SPC(统计过程控制)检测,并在包装前在测试心轴上进行100%跳动检查。

重复订单的交货期是多久?

相同尺寸和材料的重复订单10天内发货,我们常备最常用尺寸(6 mm、8 mm、10 mm)的200件库存,可实现5天发货。

请将您的图纸或简单草图(含六角尺寸和棒料公差)发送给我们。我们将在12小时内回复正式报价,包括夹头轮廓的CAD预览。如有紧急需求,可通过WhatsApp联系我们。我们处理出口文件,价格为深圳FOB或您的港口CIF。
