There is no need to change the tool during the conversion of the above process, which saves the processing time and improves the processing efficiency and precision, thus saving the cost.

附图说明Description of drawings

下面结合附图和实施例对本发明进一步说明。The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

图1是本发明的正视图。Figure 1 is a front view of the present invention.

具体实施方式Detailed ways

参照图1，本发明公开了一种连续角加工铣刀，包括刀杆1，所述刀杆1的端头设有若干均布的组合刃部，两相邻的组合刃部间设有排屑槽2，所述组合刃部包括前刀面3、后刀面4以及由前刀面3和后刀面4相交构成的组合切削刃，所述前刀面3为排屑槽2的一侧壁面，所述组合切削刃包括从刀杆1的端头到尾部依次设置的后斜直切削刃5、圆弧削刃6，所述圆弧削刃6的刃形线的半径为3mm，所述后斜直切削刃5与刀杆1中心轴线的夹角为70度。Referring to Fig. 1, the present invention discloses a milling cutter for continuous angle processing, which includes a cutter bar 1, and the end of the cutter bar 1 is provided with a number of evenly distributed combined blades, and a row is arranged between two adjacent combined blades. The chip flute 2, the combined edge portion includes a rake face 3, a flank face 4, and a combined cutting edge formed by the intersection of the rake face 3 and the flank face 4, and the rake face 3 is a part of the chip flute 2 On the side wall surface, the combined cutting edge includes a rear inclined straight cutting edge 5 and an arc cutting edge 6 arranged successively from the end to the tail of the cutter bar 1, and the radius of the edge line of the arc cutting edge 6 is 3 mm.
