产品详情

这是一套CNC加工的5C夹头圆形精密车床刀具系统——一种用于夹持圆形棒料或刀柄的卡盘,夹持精度≤0.005 mm TIR。我们将本体淬硬至58–60 HRC,将锥面磨削至Ra 0.4表面粗糙度,标准规格15天内发货。这是我们东莞工厂的精密制造产品,中国制造,标准型号无起订量。

我们如何消除5C锥度座中的跳动

跳动源于锥度。我们在CNC车床上加工5C夹头座,然后用坐标磨床精加工。结果:在整个配合长度上,锥角误差小于0.002 mm。我们用千分表在距鼻端25 mm处测量每一只卡盘。最大TIR为0.005 mm。大多数竞争对手的卡盘跳动在0.010–0.015 mm之间。这一差异会体现在您最终零件的圆度和刀具寿命上。

圆形棒料的夹持力与夹持范围

此卡盘适配直径1 mm至26 mm的标准5C夹头,以0.5 mm为增量。内部拉管提供4,500 N的轴向拉力。这相当于在20 mm棒料上产生9,000 N的径向夹持力。在200次循环中,夹持重复精度可达±0.005 mm。我们对每台设备使用校准过的扭矩扳手进行测试,确保夹头在夹持薄壁管材时不会变形。

我们使用的材料与热处理工艺

卡盘本体采用40Cr或S45C钢。粗车后,我们对锥度座进行渗碳处理,渗碳层深度为0.8–1.2 mm。工作表面硬度达到58–60 HRC。背板采用20CrMnTi,淬硬至55 HRC。随后,零件在-80°C下深冷处理2小时,以稳定微观组织。这可以防止高速生产运行中的尺寸漂移。

表面光洁度与耐腐蚀性

锥度座磨削至Ra 0.4 µm。外圆柱面为Ra 0.8 µm。本体采用发黑处理,以抵抗车间冷却液腐蚀。针对不锈钢环境,我们提供镀镍版本(厚度5 µm)。前端面经研磨至平面度0.003 mm。这一平面度确保夹头垂直就位,直接减少零件锥度误差。

每批发货前的检验

每只卡盘均经过12项检验。我们使用正弦规检查锥角,用0.001 mm千分表检查跳动,用洛氏硬度计检查硬度。我们还进行功能测试:夹持一根10 mm磨削棒料,在5个位置测量TIR,并将数值记录在测试证书上。该证书随货附上。我们不做批次抽检——100%全检。

与现有5C主轴和拉杆的兼容性

我们的卡盘可安装到任何采用1.5 mm螺距螺纹的标准5C主轴鼻端。后部螺纹为1-1/16" x 12 TPI。适配Hardinge、Royal及大多数中国车床主轴。我们附带一个拉杆适配器,兼容手动和动力拉杆。如果您的主轴采用不同螺纹,我们可在7天内加工定制背板。只需发送您的主轴图纸即可。

面向全球工程师的包装、运输与起订量

我们采用带泡沫内衬的木箱包装。每只卡盘用VCI防锈纸包裹,防止海运途中生锈。标准规格通过DHL或FedEx在15天内发货。批量订单(超过50件)海运25天内发货。标准型号起订量为1件——定制背板同样无起订量。上一季度,我们已向14个国家发货,包括德国、美国和日本。
