这款卡盘在您的自动车床主轴中的独特优势

这是一款为自动车床36型主轴设计的CNC加工夹头卡盘。它通过加长鼻端夹持圆棒料,实现更深的加工区域伸入。内孔为圆孔,口部无锥度,装载棒料时不会产生摩擦痕迹。鼻端跳动控制在≤0.005 mm。夹持表面硬度为58-62 HRC。标准尺寸交期为10个工作日。这款卡盘将您的主轴转换为刚性、可重复的夹持系统,适用于高速车削和铣削。中国制造,发货前按ISO 2768-mK标准检验。

为什么加长鼻端几何设计能减少36型车床上的刀具干涉

加长鼻端比标准卡盘端面多出25 mm的伸入量。在36型自动车床上,这可以避开主轴鼻端轴承座。您可以将切削刀具更靠近夹头端面。与使用标准卡盘加垫片相比,刀具悬伸量最多减少40%。悬伸量减少意味着振动降低。振动降低意味着长而细的零件表面光洁度更好。圆孔在热处理后进行磨削加工,而非仅车削。这消除了淬火产生的热变形。您得到的内孔在夹紧压力下保持圆度。

我们用于36型圆孔卡盘的材料和热处理工艺

我们选用20CrMnTi合金钢作为原材料。该牌号渗碳性能优异,能保持锋利刃口。本体经过车削,再铣削键槽和螺纹退刀槽。机加工后,进行渗碳处理,渗碳层深度为0.8-1.2 mm。夹持表面硬化至58-62 HRC。鼻端部分单独进行感应淬火,避免影响主体回火。背板采用40Cr材料,硬化至42-46 HRC。我们不使用45#普通碳钢。它在反复夹紧循环下会变形。我们的卡盘本体在最终磨削前进行去应力处理。这防止内孔在数千次循环后偏离圆度。

我们如何实现夹头座和内孔≤0.005 mm的跳动

跳动是三个表面的累积误差:主轴锥度、卡盘背面和夹头座。我们在坐标磨床上一次装夹加工背面和夹头座。这消除了重新装夹零件带来的误差。夹头座直径磨削公差为0.001 mm。圆孔在磨削后进行珩磨,去除进给痕迹。然后我们使用测试夹头组装卡盘,在鼻端和距鼻端50 mm处测量跳动。两个位置都必须≤0.005 mm。我们将此记录在随每个卡盘附带的检验单上。

最小起订量无最小起订量 — 可订购1件
检验100%跳动测试、硬度测试、内孔量规报告

每次发货前的检验 — 您收到的报告内容

每个卡盘都经过全面检验,而非抽检。我们使用分辨率为0.001 mm的千分表测量跳动。硬度使用洛氏硬度计在夹持表面测试。内孔使用气动量规检查圆度和锥度。我们还使用扭矩扳手在拉杆上测试轴向夹紧力。报告包括:实测跳动值、内孔直径、硬度值,以及卡盘安装在测试主轴上的照片。如果任何数值超出规格,该卡盘将被报废,绝不发货。您将在包装盒内收到报告。对于关键订单,我们还可以免费提供三坐标测量报告。

如何将这款卡盘与您现有的拉杆和夹头匹配

检查您的拉杆螺纹螺距和行程。36型自动车床使用标准M20 x 1.5拉杆螺纹。我们的卡盘背面有匹配的螺纹。如果您使用ER夹头,卡盘附带一个与加长鼻端配合的螺母。如果您使用5C夹头,卡盘有一个螺纹鼻端用于夹头闭合器。如果您提供图纸,我们还可以加工背板以匹配您的主轴鼻端。加长鼻端不会改变夹头闭合行程。您现有的拉杆行程可以正常工作。如果不确定,请将您的主轴图纸发送给我们,我们将验证配合情况。

这款夹头卡盘的最小起订量是多少?

无最小起订量 — 您可以订购单件进行测试,或进行批量生产。

你们可以定制背板或加长鼻端长度吗?

可以,我们可以根据您的图纸加工背板、鼻端长度和内孔,交期增加3天。

你们如何确保每个卡盘的质量控制?

我们对跳动、硬度和内孔几何形状进行100%检验,并随每个单元附送报告。

标准36型圆孔卡盘的交期是多久?

标准尺寸在10个工作日内发货;定制背板或鼻端长度增加3-5天。
