图中所示的凹槽铣刀的刀片为切向安装并带有正前角,其用途广泛。这种刀具特别适于在数控加工中心上铣削凹槽,它既可用于钻削,又可用于铣削。用该种刀具进行加工,可获得较高的金属切除率。这种刀具在功率较小的机床上使用时也能实现稳定的铣削加工。根据使用厂的报告,在大功率的机床上使用时,这种刀具所采用的进给速度要比高性能高速钢铣 The grooved cutter blade shown in the figure is tangentially mounted with a positive rake angle for a wide range of uses. This type of tool is particularly suitable for milling grooves on a CNC machining center, both for drilling and for milling. With this type of tooling, higher metal removal rates are achieved. This type of tool also enables stable milling when used on less powerful machines. According to the report of the use of the plant, when used on high-power machine tools, this tool feed rate than the high-performance high-speed steel milling
