产品详情

这是一套完整的数控加工ER弹簧夹头刀柄工具套装,包含铣削钻削刀具,专为需要高精度夹持但不愿支付高昂溢价的车间设计。刀柄主体采用42CrMo钢加工,淬硬至HRC 58-62,鼻端跳动(TIR)保证在0.005毫米以内。我们标准ER20和ER32套装可在10天内发货,由于我们是位于中国东莞的精密制造工厂,您能以比德国或日本刀柄低30-40%的成本获得同等品质。

ER弹簧夹头如何实现无跳动夹持刀具

ER弹簧夹头利用锥形夹头,在锁紧螺母拧紧时均匀压缩包裹刀具柄部。关键在于刀柄主体内部的8°锥角——如果该角度偏差哪怕0.1°,就会出现夹持不均和跳动。我们在内部使用Studer S41磨床磨削锥面,将角度控制在±0.002毫米以内。这就是为什么我们的TIR能保持在0.005毫米,而不是廉价供应商常见的0.015毫米。套装包含以1毫米为增量、精度达标的ER夹头,确保您的铣削钻削刀具每次都能精准居中安装。

我们使用的材料与热处理工艺

我们的刀柄主体采用42CrMo合金钢——与汽车传动系统齿轮相同的材料等级。我们进行预加工,然后真空淬硬至HRC 58-62,而非进口刀柄常见的HRC 48-52。淬火后,我们进行一次回火以消除应力,然后精密磨削内孔和锥面。锁紧螺母采用20CrMnTi渗碳淬硬至HRC 60 ± 2,轴承表面研磨至Ra 0.4 µm。由于我们使用碳势传感器控制炉内气氛,您不会看到氧化皮、脱碳层或软点。

工具套装内容:您将获得的具体配置

这是一套即装即用的套装,而非单个刀柄。您将获得:1个ER弹簧夹头刀柄主体(可选ER20或ER32),10个精密夹头(ER20规格为1-10毫米,ER32规格为2-20毫米),1个带扳手孔的淬硬锁紧螺母,1把C型扳手,以及1根拉杆(如订购BT40或BT30锥柄版本)。针对铣削钻削刀具,我们还附带一套3把ER夹头扳手(带扭矩标定)和1把清洁刷。每个夹头在包装前均单独测量TIR——任何超过0.005毫米的均被剔除。

每次发货前的检验流程

我们不进行批次抽检。每一套数控加工ER弹簧夹头刀柄工具套装(含铣削钻削刀具)均经过3阶段检验。首先,使用三坐标测量机(蔡司Contura)检查锥角、内孔直径和同轴度。其次,使用跳动测量仪在3个位置检查TIR:夹头鼻端、距鼻端10毫米处、距鼻端50毫米处。第三,我们将锁紧螺母扭矩测试至50 Nm,并验证夹头闭合无卡滞。每笔订单均附带一份签署的检验报告,包含实测TIR值——而非一张笼统的“合格”标签。

为何我们的TIR优于标准ER刀柄规格

大多数ER刀柄宣称TIR为0.010-0.015毫米。这是因为它们将锥面磨削作为独立工序,然后螺栓连接鼻端,从而引入累积误差。我们在5轴马扎克机床上一次装夹完成锥面和内孔加工,因此零重复装夹误差。结果是0.005毫米的TIR,直接提升您铣削钻削刀具的表面光洁度和刀具寿命。如果您在铝材或钢材上进行精加工,您将在第一个零件上看到差异——无振纹、无返工。如需深入了解刀具选型,请阅读我们的CNC切削刀具选型指南

适用于您机床主轴的定制锥柄选项

我们备有BT30、BT40、BT50、HSK63和直柄版本。如果您的 spindle 使用Capto或专用锥度,请将图纸发送给我们,我们将加工匹配的锥柄——前10件不收取额外刀具费用。该套装是中国制造的精密制造产品,但我们在锥柄上绝不偷工减料:锥度研磨至AT3级(ISO 1947),意味着在全量规长度上锥度误差小于0.005毫米。对于定制长度,我们可将锥柄延长至150毫米而不影响TIR。

面向CNC车间的包装与运输

每套产品均采用泡沫内衬钢制箱体包装,保护夹头和刀柄免受冲击。箱内使用防锈VCI纸,零件到达时清洁且可立即安装——首次使用前无需脱脂。对于国际订单,我们通过DHL或FedEx发货(2-5天),或大批量订购时选择海运(15-25天)。箱体尺寸为320 x 220 x 120毫米,重量为3.8公斤(ER20套装)或5.2公斤(ER32套装),因此运费可预测。我们将包裹标注为“精密刀具”,并附低价值商业发票以避免海关延误。

你们的最小起订量是多少?

无起订量——您可以订购一套数控加工ER弹簧夹头刀柄工具套装(含铣削钻削刀具)作为试用,我们仍会提供与批量订单相同的检验报告和包装。

你们可以定制夹头范围或锥柄尺寸吗?

可以,我们可以更改夹头规格(例如全公制或全英制),并加工任何锥柄锥度、长度或拉钉配置——只需发送您的图纸,我们将在12小时内报价。

你们如何控制定制订单的质量?

对于定制套装,我们生产首件并发送CMM报告和照片供您确认后再批量生产;如果首件未通过您的公差要求,我们将免费重做——请参阅我们的CNC加工公差指南了解我们可达到的精度。

该套装的标准交期是多久?

标准ER20和ER32套装10天内发货;定制锥柄或定制夹头范围需15天,因为我们需要采购原材料并编程磨削循环。

12小时内获取确定报价。发送您的图纸,或仅提供您的 spindle 类型和夹头范围——我们将回复价格、交期和刀柄技术图纸。电子邮件 sc@bquq.com 或WhatsApp +86 13713157787。无起订量,标准套装免设计费,我们从东莞工厂全球发货。
