走心机 数控车床 ER系列延长杆 钻杆
型号说明
以 SL20-ER20A-70 为例:
| 代码 | 含义 |
|---|---|
| SL20 | SL代表柄部具有侧固平面(供刀座螺丝压紧固定),20代表柄径为 20mm |
| ER20A | ER20代表适配ER20系列夹头与螺母;A代表A型六角螺母(可用普通扳手锁紧) |
| 70 | 代表柄部有效长度为 70mm |
螺母类型详解
ER延长杆的锁紧螺母主要有以下三种类型,适配不同加工场景:
| 代号 | 名称 | 结构特点 | 适用场景 |
|---|---|---|---|
| A | A型六角螺母 | 标准六角外形,可用通用开口扳手或专用扳手锁紧 | 通用加工场景,刀位空间充足,使用最便捷 |
| M | MINI迷你型螺母 | 体积小巧的轻量化紧凑型螺母,扳手位为斜槽设计 | 安装空间受限的小型雕刻机、小直径延长杆、狭窄刀位 |
| UM | 高速精密型螺母 | 预做动平衡的直槽高精度螺母,属高速加工专用型 | 数控机床、CNC加工中心的高速刀柄,高精度夹持需求 |
