一种铣削刀具
摘要：
一种铣削刀具，包含有圆盘形的刀架(1)和多个刀片(2)，多个刀片(2)均匀间隔位于圆盘形刀架(1)的周围，该刀片为硬质合金或立方氮化硼，刀架(1)上具有容纳刀片(2)的多个刀片座，刀片(2)固定在刀片座上，该刀片(2)具有前角(a)和后角(b)，该前角为6-10度，后角为17-20度，刀架(1)进行过度硬化，使得整个刀架截面上的硬度达到50HRC，该铣削刀具具有在高载荷下的高疲劳强度，且能有效避免裂纹，同时结构简单，降低成本。
摘要（英）：

The invention discloses a milling cutter which comprises a disc-shaped cutter rest (1) and a plurality of blades (2), wherein the blades (2) are uniformly positioned around the disc-shaped cutter rest (1) at intervals, and are made of hard alloy or cubic boron nitride; a plurality of blade bearings for accommodating the blades (2) are arranged on the cutter rest (1), the blades (2) are fixed on the blade bearings and are provided with front angles (a) of 6-10 DEG and rear angles (b) of 17-20 DEG; and the cutter rest (1) is excessively hardened so that the hardness of the section of the cutter rest reaches 50HRC (Rockwell hardness). The milling cutter has high fatigue strength under a high load, can effective avoid cracks, and has the advantages of being simple in structure and reducing cost.
