这是一款CNC加工自动车床52型六角孔弹簧夹头,专为在走心式和固定主轴自动车床上夹持六角棒料而设计。您可获得夹持直径处保证的0.005 mm总指示跳动(TIR)、Ra 0.4 µm的表面光洁度,以及HRC 58-60硬度的淬硬本体,可在200,000次以上循环中保持几何精度。标准尺寸的交货期为10-15个工作日,我们从东莞工厂全球发货。

为何52型六角孔夹头优于圆孔夹持

六角棒料的旋转和滑动方式与圆棒不同。圆孔夹头仅在两个点上接触平面,导致振动并在工件上留下痕迹。我们的52型六角孔弹簧夹头采用完全成型的六角形凹槽,具有120°角间距,与棒料横截面精确匹配。这可将夹紧力分布到所有六个平面上,与圆孔等效夹头相比,棒料回推减少30%。对于以6,000 RPM运行的自动车床,这意味着更少的废品和更长的刀具寿命。

材料选择与热处理,确保20万次循环寿命

我们采用20CrMnTi合金钢,这是一种精密制造中常见的渗碳钢种。在CNC加工内孔和槽后,我们进行渗碳处理,渗碳层深度为0.8-1.2 mm,然后淬火和回火至表面硬度HRC 58-60。芯部保持在HRC 35-40,为夹头提供足够的回弹灵活性,使其能够开合而不会开裂。我们不使用12L14或1215易切削钢——这些钢种在生产环境中磨损过快。

槽几何形状:抓取与夹持的区别

弹簧夹头在槽过宽(失去同心度)或过窄(无压缩范围)时会失效。我们激光切割三个槽,间隔120°,每个槽宽0.3 mm、长25 mm,距后端面8 mm处停止。这提供了六角尺寸上0.2 mm的压缩范围,足以应对供应商棒料公差的变化。槽边缘去毛刺至0.1 mm半径,因此高速装载时不会划伤棒料。

每次发货前检验:无批次抽样

每一件夹头——而非随机样品——在离开我们东莞工厂前都经过三项检查。首先,三坐标测量机(CMM)根据您的图纸验证六角孔轮廓。其次,测试卡盘测量距鼻端20 mm和50 mm处的TIR,并将两个数值记录在检验报告中。第三,硬度测试确认夹持表面HRC 58-60。任何夹头不合格即报废。每笔订单随附一份签署的检验报告,简化您的来料检验流程。

与常见自动车床品牌的兼容性

我们的52型六角孔弹簧夹头适配标准DIN 6343安装模式,可直接用于Star、Citizen、Tsugami和Hanwha走心式车床。它也适配许多台湾机床,如JSL和Fidelity。如果您有非标准主轴鼻端,我们可按您的规格加工后锥度和螺纹——这是定制选项,交货期延长5天。将您当前的夹头卡盘图纸发送给我们,我们将精确匹配拉回距离。

定制六角尺寸和特殊内孔轮廓

标准六角尺寸从3 mm到32 mm,常用规格备有库存(3、4、5、6、8、10、12、14、16、19、22、25、32 mm)。对于7.5 mm或11 mm等非标尺寸,我们按您的图纸加工内孔,公差同样为0.005 mm。我们还从相同的52型本体制造方形、三角形和双D形内孔。定制形状的最小订单为一件——这是我们所有产品均适用的无起订量政策。

此夹头的最小起订量是多少?

无起订量——我们接受标准和非标六角尺寸的单件订购。

能否将六角孔定制为非标尺寸?

可以,我们可加工3 mm至32 mm范围内的任何六角尺寸,公差为+0.005 / -0.005 mm,单件定制内孔交货期为7天。

大批量订单如何确保质量控制?

每件夹头均经过CMM、TIR测试和硬度检查的单独检验——无批次抽样,每次发货均附有签署的检验报告。

标准52型六角夹头的交货期是多久?

库存尺寸在10-15个工作日内发货;定制尺寸增加5天加工时间,紧急订单可提供快递服务。
