我们加工用于传动系统壳体、传感器支架和阀体的CNC加工汽车零部件及组件。您可获得±0.005毫米位置公差、关键孔0.008毫米跳动度以及耐磨表面58 HRC硬度。典型交期为原型7天、批量生产15天,我们从拥有20年精密制造经验的东莞工厂发货。

为何我们的3轴和5轴铣床比您现有供应商保持更严格的公差

我们运行12台Fanuc控制的加工中心,包括两台5轴DMG MORI设备。所有机床安装在环氧树脂灌浆基础上,消除振动漂移。我们在首次切削前对每个夹具进行探测,并每加工50个零件后重新探测以捕捉热膨胀。这就是我们能在铝材上保持±0.005毫米、不锈钢上保持±0.008毫米公差的原因。如果您当前的零件在0.02毫米处失效,您将看到配合和噪音方面的差异。

适用于发动机舱和底盘工况的材料与热处理

我们加工6061-T6和7075-T6铝材用于轻量化支架。对于转向节和悬挂连杆,我们使用4140铬钼钢,热处理至28-32 HRC。如果您需要耐磨性,我们提供8620渗碳钢至58-62 HRC。我们还切削304和316L不锈钢用于排气法兰和传感器壳体。每批材料附带钢厂证书,我们使用洛氏硬度计验证每批硬度。

我们如何控制旋转部件的跳动度

汽车皮带轮、主轴和电机轴不能承受摆动。我们在5轴铣床上通过单次夹紧操作加工这些零件,消除重新装夹误差。然后我们在Talyrond圆度仪上检查TIR(总指示跳动)。我们保证直径小于50毫米的零件TIR为0.005毫米,较大零件为0.01毫米。如果您曾因振动而提前更换轴承,这就是解决方案。

可承受10,000小时运行的表面光洁度和边缘处理

我们使用80巴高压冷却液切削以防止积屑瘤,在铝材上获得干净的0.8 Ra光洁度,钢材上为1.6 Ra。对于密封表面,我们可以抛光至0.4 Ra。除非您的图纸另有规定,我们为每个尖锐边缘倒0.2毫米圆角。这防止了循环载荷下产生裂纹的应力集中点。我们还通过流穿式磨料工艺去除内部交叉孔的毛刺,确保没有松散切屑进入您的装配线。

每次发货前检验:CMM和三坐标光学报告

我们不会在没有完整检验报告的情况下发货。我们的Zeiss三坐标测量机检查所有关键尺寸,光学比较仪验证螺纹形状和小半径。每个包装箱附带材料证书、硬度报告和表面光洁度曲线。如果您需要PPAP Level 3,我们为汽车Tier 1和Tier 2客户提供。我们保存记录10年,使您可以将任何零件追溯到其原材料炉号。

CNC切削刀具选择与公差策略

刀具磨损是汽车零件尺寸超差的首要原因。我们使用涂层硬质合金刀片加工钢材,PCD刀具用于大批量铝材生产。对于深腔和薄壁,我们动态调整进给速率以避免偏转。如果您正在设计新零件,请阅读我们的CNC切削刀具选择指南以避免昂贵的换刀成本。对于紧密配合,我们的CNC加工公差指南说明了我们在不同特征上可保持的公差。

无最小起订量的中国制造零件定价与物流

我们是一家中国制造工厂,但定价如同本地机加工车间。我们的小时费率为$45,根据循环时间加装夹时间按件报价。无最小起订量——您可以订购1个原型或50,000件。对于批量生产,我们提供带计划发货的框架订单。我们通过DHL或FedEx发送原型(3-5天到达美国),大宗订单通过海运。我们处理出口文件,并可通过激光蚀刻在零件上标记您的零件号和炉号。
