这是一款BT40弹簧夹头刀柄,配备ER32弹簧夹头,由20CrMnTi合金钢整体坯料加工而成。它可夹持立铣刀和钻头,刀尖处总指示跳动(TIR)≤0.005毫米,夹头锥度磨削至16°夹角,表面粗糙度Ra 0.4 µm。标准规格产品15天内发货,夹持表面经渗碳淬硬至HRC 58-62,可在高扭矩CNC铣削中保持长久使用寿命。

ER弹簧夹头如何在不使用液压或热缩配合的情况下锁紧刀具

ER夹头是一种开槽钢套,当锁紧螺母拧紧时径向收缩。BT40锥度(7:24)将刀柄主体定位在主轴中,而夹头内孔夹持刀杆,每个夹头规格的夹持范围为1毫米。例如,ER32夹头覆盖2–20毫米的刀具直径,每个单独夹头覆盖1毫米范围(如10–11毫米、11–12毫米)。这消除了液压膨胀或感应加热的需求,车间换刀时间不到30秒。

我们用于BT40刀柄主体的材料与热处理工艺

刀柄主体由20CrMnTi(一种低碳合金钢)加工而成,该材料对渗碳处理响应良好。我们将锥度和夹头座进行表面渗碳淬硬,深度为0.8–1.2毫米,表面硬度达到HRC 58-62。芯部保持HRC 30-35的韧性,可吸收断续切削时的振动。拉钉(MAS BT-403型)由42CrMo制成,整体淬硬至HRC 40-45,在10,000转/分钟的主轴负载下不会拉伸变形。

磨削顺序确保装配后0.005毫米跳动精度

大多数供应商分别磨削锥度和夹头座,这会导致跳动误差累积。我们首先磨削BT40锥度,然后将刀柄主体安装在精密心轴上,磨削夹头座使其与该锥度同心。最终装配跳动使用插入夹头的10毫米测试棒进行检测。我们的标准是在距刀尖50毫米处≤0.005毫米;如果您需要≤0.003毫米用于精加工,我们可以选配并匹配单个夹头,需收取少量附加费用。

表面光洁度与涂层选项:排屑与耐腐蚀性

外表面光洁度为Ra 0.8 µm,而锥度和夹头座磨削至Ra 0.4 µm。标准配置为黑色氧化处理,可防轻锈并提高润滑性。对于大量使用冷却液的环境,我们提供在刀柄主体上镀氮化钛(TiN)涂层,可将表面硬度提升至HV 2200并降低摩擦系数。该涂层会增加3天交期,但推荐用于铝加工,因为铝屑容易焊接到钢材表面。

每次发货前检测:锥面接触率与拉钉扭矩

每支BT40刀柄均使用锥度规检测接触面积——我们要求7:24锥面上的接触率至少达到90%。拉钉拧紧至65 N·m,并标记扭矩条纹以显示运输过程中未松动。我们还使用通止规验证夹头螺母螺纹(M40 × 1.5),并在刀柄主体上记录序列号,以便追溯至东莞工厂的热处理批次和磨削日期。

为什么这是无起订量的中国制造选项

我们拥有4,500平方米的工厂,配备20台CNC车床和12台外圆磨床,因此无需将您的订单与其他客户合并批次即可盈利。您可以订购单支BT40弹簧夹头进行测试,或订购500件用于生产线。单价从1件时的38美元降至50件时的22美元(不含夹头)。所有精密加工均在厂内完成,从原材料毛坯到最终磨削,这就是我们能够以日本或德国品牌60%的价格保持同等公差的原因。
