在铣削加工中,往往由于铣削经过热处理的硬质材料或难加工材料而造成刀具的磨损,或者为了补偿刃磨时产生的铣刀直径的变化,而采用图示的回转型铣头。铣头体6相对于底座3以销轴12为回转中
In milling, tool wear is often caused by the milling of hard-to-heat or hard-to-machine materials, or rotary milling heads of the type shown are often used to compensate for mill diameter changes during sharpening. The milling head 6 is pivoted relative to the base 3 about the pin 12
