装圆刀头的端铣刀,可用于精铣和半精铣淬火钢、铸铁和青铜零件的平面.圆刀头是一圆柱体,其侧面起前面作用,其端面起后面作用,而两者的交点则形成圆弧切削刃.四个圆刀头成负前角装入铣刀体孔内并用螺钉紧固.利用调节螺钉和螺帽,按指示表调节圆头的伸出量.随着切削刃有效部分的磨损,将圆刀头绕轴线旋转,便可使新的圆弧切削刃参加工作,直至刀刃全部长度磨损为止.圆刀头转动的次数由切削刃有效部分长度决定,根据具体情况可转动4至8次.刀头的刃磨和研磨用普通刃磨机进行,只磨后面(端 Round cutter end mill, can be used for finishing and semi-finish hardened steel, cast iron and bronze parts of the plane round head is a cylindrical body, the side from the front of the role of the end of its role from the back, and both Of the intersection point of the arc cutting edge is formed. Four circular cutter into a negative angle into the mill body bore and screwed with the use of adjusting screws and nuts, according to the instructions to adjust the round head of the projection. With Cutting the effective part of the wear and tear, the circular knife around the axis of rotation, you can make the new arc cutting edge to participate in the work until the entire length of the blade wear so far round knife rotary cut the number of effective parts of the length of the decision, depending on the specific The situation can be rotated 4 to 8. Sharpening and grinding head with a common sharpener, grinding only the back (end
