The utility model relates to a high speed steel plated screw taper for numerical control equipment, which solves the problem that when the existing common taps are processed, the iron chips are easy to stick to the processed threads, easily lead to the drop of the thread smoothness, seriously damage the thread and affect the thread precision, and the two sides of the taps are set with a slots on both sides of the thread. The cuttings trough is concave arc, the front end of the chip slot is set with a deepened snails slot, the snails slot is concave arc, the screw slot faces the side edge of the cutting edge of the taper thread to the screw tip to the taper thread, and the side depth of the edge is gradually increased. The tip slot is deepened, the tip groove is concave arc, the spiral groove is deepened from the arc of the chip slot to the center of the taps, and the arc of the spiral groove is deflected, so the taps are removed from the front of the taps when the taps are tapped, so that the iron chips will not go with the taps. The thread is damaged by processing thread.

数控设备用高速钢镀层螺尖丝锥
本技术涉及一种丝锥,尤其是一种数控设备用高速钢镀层螺尖丝锥。
技术介绍
在工件上加工内螺纹,一般都用到丝锥,通过转动丝锥的螺纹段来完成内螺纹加工。但是,普通丝锥加工螺纹铁屑容易粘在被加工螺纹上,造成螺纹光洁度下降,严重的话还会拉伤螺纹,影响螺纹精度,所以用丝锥加工螺纹时的切削速度不能太快,否则铁屑卡在螺纹里,还会造成丝锥断裂,因此普通丝锥对难加工材料(比如不锈钢、钛合金等)不容易攻丝。
技术实现思路
本技术解决了现有的普通丝锥在加工螺纹的时候,铁屑容易粘在被加工螺纹上,容易造成螺纹光洁度下降,严重的还会拉伤螺纹,影响螺纹精度的缺陷,提供一种数控设备用高速钢镀层螺尖丝锥,丝锥两侧设置有导屑槽,在导屑槽的前端设置有加深的螺尖槽,使得铁屑可以从丝锥的前端排出,不会留在螺纹孔内影响螺纹精度。本技术的具体技术方案为:一种数控设备用高速钢镀层螺尖丝锥,丝锥的两侧设置有导屑槽,导屑槽呈凹弧状,导屑槽的前端设置加深的螺尖槽,螺尖槽呈凹弧状,螺尖槽朝向丝锥螺纹切削前刃的侧边到螺尖槽朝向丝锥螺纹切削后刃的侧边深度逐渐加大。导屑槽前端设置加深的螺尖槽,螺尖槽呈凹弧状,螺尖槽是从导屑槽的弧形面向丝锥中心部位加深,而且螺尖槽的弧形相对导屑槽的弧形是呈偏转的,因此丝锥在攻丝的时候,铁屑从丝锥的前端排出,这样铁屑就不会随丝锥进入到被加工的螺纹处,对加工的螺纹造成伤害。作为优选,丝锥的前端为锥形光段,丝锥螺纹段的前段为锥形状,后段为柱形状,导屑槽从丝锥前端一直延伸到丝锥螺纹段结束。作为优选,导屑槽的深度从丝锥前端向后逐渐变浅。作为优选,丝锥螺纹段后端为柄部,柄部 ...
