数控刀具的小编聊聊螺纹柄英制钴高速钢内冷短麻花钻是应用广泛的孔加工刀具,通常直径范围为0.25~80毫米,它主要由工作部分和柄部构成,因为工作部分有两条螺旋形的沟槽,形似麻花,因而得名,螺纹柄英制钴高速钢内冷短麻花钻的优点在于:

1.节约钢材,其成型加工是通过成型铣刀除毛坯材料的方法加工出螺旋槽,而它的成型加工是无屑加工,能够对毛坯外圆反复轧制使材料挤压拔长,然后通过扭槽机加工出螺旋槽,所以,更节约了高速钢材料。

2.生产效率高,以26mm锥柄麻花钻为例,对铣削加工麻花钻的沟槽及清边时,铣削工时每件为3.5min;而采用轧扭制方法只要0.5min,使其生产下来得到了提高。

3.提高内在质量,在成型加工时槽形需经过反复轧制,并且不破坏金属内部纤维,材料芯部组织更致密,产品芯厚增量参数较稳定,由于是在高温下产生的变形,因此起到细化晶粒组织的作用,改变了碳化物分布,使其更均匀,从而提高了内在质量。

4.提高产品硬度,由于内部晶粒细化,热处理后轧,工作部分硬度可达到65.3-65.8HRC,而采用铣制方法加工的麻花钻热处理后,工作部分硬度只能达到64.5HRC左右。
